Basic Information

Virtual office This is a service that provides you with an address which you can use to register your business and for correspondence, as well as to display on your website, Facebook page, business cards and marketing materials – in accordance with the terms of the contract and the terms and conditions. 

By choosing Biuro31, you’ll benefit from: 

  • optimisation of operating costs 
  • privacy 
  • freedom of action – without having to be tied to a single location 
  • a professional business address in the centre of Poland’s largest cities 

The term „virtual office” does not mean that there is no office – the premises at the specified address actually exist and you may use them within the scope set out in the contract and the terms and conditions. 

The service is mainly used by business owners, but also companies and organisations – foundations, associations – as well as private individuals who do not run a business.

Yes – it’s only ‘virtual’ in name. You’ll find photos of our premises in each city in the section gallery.

No. From virtual office It is also available to private individuals who do not run a business, as well as organisations – associations, foundations and other entities. 

The only difference is that for individuals and organisations not engaged in business activities, we issue a personalised invoice without a tax identification number. 

You can use the address, for example, as a correspondence address to share with others for contact purposes, on a website, on business cards, on Facebook or for unregistered business activities. 

We realise that’s a lot of information to take in at the start, so in a nutshell: 

  • You’re renting from us for a year the address for company registration and/or the correspondence address – You can use it when registering your business, as your company’s registered office, on your website, on Google and elsewhere. 
  • Once the contract has been signed and paid for, we’ll collect any post addressed to you that arrives in our postbox. You’ll receive an email notification for each item, including a photo (of the delivery notice or envelope) and instructions on how to collect it – either yourself or via a designated person. 
  • If you receive a delivery notice, you can collect your letter from your local post office. Registered letters can be collected in Poznań as part of Premium package. 
  • We transfer the letters that arrive in our postbox to our premises, into a system of lockable compartments fitted with electronic locks – each compartment has a changeable PIN assigned by us. 
  • You have 3 days from receiving the email notification to collect your letter. 
  • We will store any letter not collected on time free of charge in our archive – you can collect it at a time that suits you. 
  • We can scan your correspondence on request – this is an additional service, charged separately. 
  • As part of your annual subscription, you get 10 hours’ access to the premises – e.g. for remote working or a meeting with a client. The venue operates on a co-working basis, so there may be other customers there during your visit, such as those collecting their post. 
  • You can contact us by email, via chat, by phone or remotely. You sign the contract online – no need to print, scan or sign anything. 

Our operations centre is based in Poznań, where staff are available every day from 8.00 am to 4.00 pm – you can collect your post there yourself or ask the team for assistance. 

In other towns, the service operates entirely remotely, and correspondence is collected on a self-service basis – this enables us to maintain an efficient, automated process at every location. 

You can find more information in the other sections of the FAQs and on the website detailed offer. If you haven’t found what you’re looking for, please get in touch with us: biuro@biuro31.pl.

On a permanent basis – no one. Our staff come to the premises to handle customers’ correspondence, whilst customers come to collect their post, do some work or hold a meeting. The exception is Poznań, where our operations centre is based – there, the team is on site every day from 8.00 am to 4.00 pm. 

There are several ways you can contact us:

  • by email: biuro@biuro31.pl
  • via contact form
  • in Messenger chat (the icon in the bottom right-hand corner)
  • by telephone: +48 22 600 25 00 (landline number, Warsaw area code)

Most of the information you need – including contract template i details of the offer – You can find it on our website.

Safety and Legality

Yes, it is entirely legal. The virtual office service – providing premises for business purposes and handling correspondence – is lawful. By entering into a contract with us, clients acquire the legal right to use our address in the CEIDG or KRS registers. No authority has any grounds to question the legality of a company operating at an address where many other entities are registered – attempts to refuse to issue a tax identification number (NIP) or VAT registration to companies using virtual offices have been overturned by Polish courts, and this issue no longer arises. 

We also hold a certificate from the National Tax Administration (KAS) confirming our entry in the Register of Activities for Companies or Trusts – registration number RDST-380. 

If necessary, you can also arrange a meeting with an official at our office – simply book in advance.

There are many virtual offices on the market. Biuro31 stands out primarily for its technological approach: 

  • Automation and a state-of-the-art system – We build our processes – from contract signing to the receipt of correspondence – around automation and IT tools. This allows us to minimise red tape and maintain efficient, predictable service – and we pass on the time and cost savings to you in the form of a stable service price that remains unchanged year on year. 
  • Access to the office 24/7 or from 6.00 am to 10.00 pm – Whilst other offices close at 5.00 pm on Friday and open at 9.00 am on Monday, we offer non-stop access or extended opening hours, depending on the location. You can even collect your letter at 3.00 am on a Saturday. 
  • Fully contactless – Access to the office is fully automated, so you can collect your post without coming into contact with anyone else. 
  • A fully online contract, available 24/7 – We don’t require you to print, sign, scan or return the contract. Our system generates contracts automatically, so you can sign one even at the weekend or in the middle of the night. 
  • Simplicity and transparency – we describe the scope of our services in detail in detailed offer, we provide a draft contract for you to review before it is signed, and we clearly explain how we handle correspondence, archiving and scanning. 

We invite you to conclusion of a contract.

A virtual office is not for: 

  • carrying out unlawful activities 
  • concealing one’s identity from the authorities or creditors 

Companies registered at the same address may indirectly affect its reputation; therefore, we verify every client before entering into a contract, in accordance with applicable law. 

We also work with tax offices, customs authorities, bailiffs, courts and the police – should we receive an official enquiry or suspect that a customer is breaking the law, we will pass on their details to the relevant authorities.

No. We do not consider owning property to be a significant asset – it is a cost that would affect the price of the service without offering any real benefit to the customer. 

By entering into long-term tenancy agreements (with the option to extend), we acquire the right to operate a virtual office on the premises in question, always with the owner’s knowledge. 

It is not in our interest to cease operations at a given address of our own accord – our approach is long-term, and keeping unnecessary costs to a minimum enables us to maintain stability.

It sometimes happens that companies register using our office address without having entered into a contract with us and without paying the service fee. This has serious legal consequences. 

We are in constant contact with the tax offices and regularly report companies that are listed under our address in the CEIDG, KRS or VAT registers but are not our clients. The tax office then initiates proceedings to remove such a company from the VAT register and subsequently from the CEIDG or KRS – on the grounds of a lack of legal title to the address. Furthermore, VAT invoices issued by such a company and any tax refunds may be challenged. 

Any correspondence sent to our office address and intended for a company using the address without a contract will be destroyed. 

That is why you should always sign a contract with us first, and only then register your company at our address.

Scope of Services

Once we have received your letter, we will send you an email notification with a photo of the envelope (showing the sender’s details), the PO box number, PIN code the collection date, the PIN’s expiry date and directions to the office.

W Poznań and Warsaw access to correspondence is possible 24 hours a day, 7 days a week. At other locations, post can be collected every day between 6:00-22:00. 

Access to the premises is granted via a personal PIN code, which you receive once you have paid for the contract – the code remains active for the entire duration of the contract.

The standard retention period for correspondence in a post office box is 3 days (72 hours) from the time you receive the email notification. After this time, the parcel is moved to the archive, where it remains for the entire duration of the contract. You can request that it be returned to your locker at any time and collect it at your convenience – see the section „What happens to uncollected mail?” below.

In the email notifying you that you have new post to collect, you will find details of how long the PIN is valid for. 

The PIN works in two places: at the front door and at the postbox itself. Once it has expired, you will not be able to enter the premises or collect your post from the postbox. 

If your PIN has expired, log in to Customer Panel and check the „Lists” section to see the status of your list. You can also retrieve your username and password from there if you’ve forgotten them. 

A letter can have one of several statuses: 

  • In the safe – The letter is in the safe deposit box, and the PIN is still valid (the exact date is shown in the Dashboard and in the email). 
  • After the deadline – The letter is still physically in the pigeonhole, but our staff member hasn’t had time to move it to the archive yet. 
  • Archived – The letter was transferred to the archive by one of our staff members. 

If the status is „Overdue”, you can click the mode icon on the right-hand side in the Customer Panel and extend the PIN’s validity by 24 hours – this is an automatic process, and you’ll receive confirmation straight away. 

If the status is „Archived”, you can use the same icon to request that the letter be moved from the archive to your personal locker. A member of staff will do this during their next visit to the premises – in practice, within 0–3 working days. Once the letter has been returned to the locker, you’ll receive a new email notification with the locker number and PIN, and you’ll have 48 hours to collect it. 

You carry out all the management yourself via the Customer Portal – there are no other methods apart from those described above.

Mail that is not collected within the specified time (as set out in the contract and in the email, usually 3 days – 72 hours) is placed in the archive – a lockable metal cabinet on our premises, to which only our staff have access. 

In response to your request, submitted via Customer Panel, we will transfer the post from the archive back to your PIN locker the next time a member of staff visits. You will then receive an email notification, and you will have 48 hours to collect it. 

If you fail to collect it within that time again, the post will be returned to the archive, and any subsequent transfer of the same item to your postbox will incur a handling fee 10 zł net. 

Go to Customer Panel and click on the link to retrieve your login details. You’ll receive your username and password via text message – the same password is used to log in to the venue booking system and as the PIN for the office door. 

Please note: you will only open the door if you have post to collect (you have received an email about this) or an active booking made via Reservation portal.

Yes. Scanning is an optional service available on request – it is not included in the annual subscription (see price list).

Unlimited scanning is also available as part of Premium package.

The scanning service works as follows: 

  1. When you receive a letter, you’ll get an email notification with a photo of the envelope.
  2. Information about the new list also appears in Customer Panel. 
  3. To order a scan, log in to the Customer Portal and, in the „Tokens” section, select the package that best suits your needs. 
  4. Once you have placed your order, you will receive an email containing a pro forma invoice for payment.
  5. Once the payment has been processed: we issue VAT invoice 23%, credit your account with the purchased tokens, and you can request a scan of the correspondence. 

To request a letter to be scanned: 

  1. Log in to Customer Panel. 
  2. In the „Lists” section, tick the box to the left of the parcel. 
  3. Under the list of correspondence, select „Scan” and click „Proceed”. 

We will scan the document during the employee’s next visit to the office and send it by email. 

The price of the scan is 5 PLN net + 23% VAT for a letter of up to 5 pages, for example: 

  • 1 letter, 5 pages = 5 PLN net + 23% VAT 
  • 1 letter, 7 pages = 10 PLN net + 23% VAT 
  • 2 letters, each 1 page = 10 PLN net + 23% VAT 
  • 2 letters, 4 pages each = 10 PLN net + 23% VAT 
  • 2 letters, one 2 pages, the other 7 pages = 15 PLN net + 23% VAT 

Detailed token price list: 

  • 5 tokens = 25 PLN net + 23% VAT 
  • 10 tokens = 45 PLN net + 23% VAT 
  • 20 tokens = 85 PLN net + 23% VAT 
  • 50 tokens = 200 PLN net + 23% VAT 

One token allows you to scan a letter of up to 5 pages. A 7-page letter requires two tokens.

Yes. The cost of return postage is 25 PLN (net) plus the cost of posting the parcel via a parcel locker and any packaging required. 

To arrange a return, please email us at biuro@biuro31.pl. We will issue a pro forma invoice for 25 zł net — once you have paid it, please send us the parcel tracking code for the Paczkomat, and we will pass it on to our staff, who will dispatch the parcel.

This question usually relates to parcels that require a signature from the addressee or an authorised person. 

As part of Premium package In Poznań, we can, in certain cases, collect such post. In other locations, this service is not available. 

In our offices, staff are not present on site for 8 hours a day, from Monday to Friday. The exception is Poznan — our operations centre, where the team is available every day from 8.00 am to 4.00 pm. As part of Premium package In Poznań, we also collect selected registered post. 

At our other offices, staff visit the office several times a week, once a day, to deal with clients’ correspondence. As a rule, therefore, we do not accept deliveries requiring a signature on receipt or courier parcels. 

However, we do accept any correspondence that can be placed in our postbox — this also applies to most registered letters, provided the sender uses the service "Recommended to the box" offered by Poczta Polska (Check on the Poczta Polska website). 

If the postman or courier is unable to deliver the parcel, they will leave a delivery notice in our letterbox – we will then send you a photo of it so that you can collect the parcel in person or via an authorised representative at the post office. 

In the case of parcels, courier companies often allow you to have your parcel left at the nearest collection point (POP) or redirected to a different address — it’s worth checking the details directly with the courier. 

Thanks to the electronic access system, our clients have round-the-clock, self-service access to the office — without the need for a permanent receptionist, which also affects the price of the service.

Our staff collect post from the letterbox at least twice a week on weekdays — this is guaranteed by contract. We organise this so that collections do not take place on two consecutive days (e.g. Monday and Wednesday, Tuesday and Thursday/Friday, or Wednesday and Friday). 

As the number of customers in a given city increases, the frequency rises until deliveries are made daily. Currently: 

  • Poznan – every day (Monday–Friday) 
  • Warsaw – every day (Monday–Friday) 
  • Wrocław – every day (Monday–Friday) 
  • Krakow – every day (Monday–Friday) 
  • Łódź – 3 times a week (Monday, Wednesday, Friday) 
  • Katowice – Twice a week (Tuesdays, Fridays) 
  • Gdansk – 3 times a week (Monday, Wednesday, Friday) 

We send an email notification as soon as an employee checks their inbox. In practice, given the frequency of checks described above, you will receive them within 0-3 working days from the date the letter or notification is placed in our letterbox.

No. Lockers are not permanently assigned to a customer — each new parcel may be delivered to a different locker, with a different PIN, which you will receive in an email notification. 

Each company has a separate PIN, which is valid for the duration of the contract. You will receive it by email once you have paid for the contract, along with further information about the service. 

It’s worth making a note of it — and if you have several companies registered with us, make a note of all the PINs and assign them to the relevant companies. 

Why is this important? When a parcel arrives for collection, we’ll send you an email notification with a photo of the envelope, so it’ll be clear which company it belongs to. However, you’ll only be able to open the door using the PIN for the company that currently has post to collect — other PINs won’t work at that time. This is a deliberate security measure, as there have been instances where customers have come to the premises without any post to collect and without a booking. 

You will only be allowed to enter the premises if you have post to collect or an active booking within the hourly time limit — you can make a booking via Reservation portal.

Yes. As well as a business address, the service gives you access to physical office space — 10 hours a year arising from the contract.  

You make the booking yourself at online booking system — You’ll be given an account once the contract has been signed. 

The space operates on a co-working basis: a booking does not grant exclusive use. Other customers will not be able to book the space at the same time (the system does not allow this), but they will still be able to come in to collect their post — their PIN will not be blocked whilst you are there. 

We do not offer separate meeting rooms. Our premises usually consist of a single room with a system of lockers for collecting your own post, as well as desk spaces where you can, for example, work within the hourly limit specified in your contract. 

There are exceptions to this — in Poznan i Gdansk We have a dedicated, separate space for work and meetings. If you’d like to organise a meeting at one of our venues, please email us and let us know the city — we’ll let you know what venues we have available there. 

The premises operate on a co-working basis: as part of the virtual office service, you get 10 hours’ access to the office, but a booking does not grant exclusive use of the entire premises. When you book a specific day and time, other customers will not be able to book the premises at the same time (the booking system does not allow this), but they will still be able to come in to collect their post. 

You can find the full range of services on the website detailed offer — including information on The Premium Package i price list. 

Yes. As part of the virtual office service, you can use the workspace for 10 hours, in accordance with the terms set out in the contract. Our premises operate on a co-working basis, so booking a time slot does not mean you have exclusive use of the entire space. During your booked time slot, other customers will not be able to make a booking, but they may still enter the premises to collect their post. 

In Poznań and Gdańsk, there are separate rooms available for work and meetings. In other locations, the possibility of organising a meeting depends on the layout of the venue in question. Please contact us and let us know which city you’re interested in, and we’ll let you know what options are available. 

You can find the full range of services in the section detailed offer.

Conclusion of Contract and Price List

The total cost of the service depends on the contract term you choose. We offer contracts for 3, 6, 12 and 24 months. You can find details of the price in price list. 

Our proprietary IT solutions enable self-service collection of mail and access to the office during extended opening hours, whilst maintaining a high standard of service. 

For customers interested in additional benefits, the following is available: Premium package in Poznań – Its main advantages are the ability to collect registered letters and unlimited scanning of correspondence.

It depends on the number of companies. For two or three, the price is standard — 2 or 3 times the amount of the chosen subscription. For a larger number, the price is negotiable, although the discount will not be in the tens of per cent — our base price already takes into account the savings from process automation. 

For individuals, you can sign the contract earlier – for example, on 20 December – and enter the date of your planned registration with CEIDG as the start date of the service, for example, 1 January. This is an option for those who prefer to have everything prepared in advance rather than at the last minute. In this example, the contract runs from 1 January to 1 January of the following year, even though it was signed on 20 December. 

For companies, the agreement should take effect from the date the articles of association are drawn up – because it is the articles of association, even before entry in the National Court Register (KRS), that specify our address as the company’s registered office. 

Would you like to use the address as a private individual, without running a business? The whole process is available online at 100% – no printing, scanning or visits to the office required. 

  1. Select a location (town) and the status „No business”. Enter your details, mailing address (Your actual contact address, not our office address), start of the contract (no earlier than today) and the address on the invoice: „Our virtual office address”. Send form. 
  2. Do verification transfer 1 grosz from your personal account – it must not come from an account held in the name of our office. You’ll find the account number in the tab Contact. 
  3. Confirm that you wish to enter into the contract by text message — reply to the message we will send you.
  4. Once both steps have been completed, we will automatically generate a contract and a pro forma invoice. Once payment has been made, you will be granted access. As a consumer, you have 14 days to withdraw from the contract.

Are you setting up a sole trader business but haven’t yet been registered with CEIDG? You’ll need to enter into the contract as a natural person, using the 100% online form. 

  1. Select the location and the status „New business” → „sole trader”. In the field Company name Enter just the name, without the legal form, and list yourself (the owner) as the representative. Complete mailing address (Your actual address, not your office address) and your contact details. Commencement of the contract set the date as the date of registration with CEIDG or an earlier date — the agreement cannot be dated later than the registration, as this would imply the use of the address without a contract. Send form. 
  2. Make a verification transfer of 1 grosz from the owner’s personal account — it must not come from an account registered to our office’s address. The account number can be found in the tab Contact. 
  3. Confirm that you wish to enter into the contract by text message – reply to the message we will send you.
  4. Once both steps have been completed, we will generate a contract (in your name) and a pro forma invoice. Once you have registered with CEIDG, please contact us and provide your NIP – we will issue a VAT invoice to your company, which you can claim as a business expense.

Are you setting up a limited company? It comes into existence as soon as the articles of association are signed (as a „company in the process of being formed”), which is why we sign the office lease agreement on the day the articles of association are signed. The process is carried out online via 100%. 

  1. Select the location and the status „New company” → limited liability company / public limited company / PSA. You will see a message stating that the entity is established upon the conclusion of the articles of association. Complete the details and submit the form.
  2. Make a verification transfer of 1 grosz from the private account of the person setting up the company — it must not come from an account registered to our office’s address. The account number can be found in the tab Contact. 
  3. Confirm via text message — reply „YES” to the message we’ll send you.
  4. Once we have received confirmation via text message and the bank transfer has been completed, we will send you an email containing consent to the disclosure of our address (PDF) and the contract.
  5. Once the company has been registered with the National Court Register (KRS), please provide your NIP and REGON numbers — we will complete the details, and once the pro forma invoice has been paid, we will issue a VAT invoice.

These companies do not have their own legal personality — we enter into an office lease agreement once they have been entered in the relevant register (CEIDG for a civil-law partnership, KRS for the others). The process is carried out online via 100%. 

  1. Select the location and the status „New company” → [type of company]. You will see a message stating that the entity is established upon the signing of the articles of association. Complete the details and submit the form. 
  2. Make a verification transfer of 1 grosz from the personal account of the person authorised to represent the company — it must not come from an account held in the name of our office. The account number can be found in the tab Contact. 
  3. Confirm via text message – reply „YES” to the message we’ll send you. 
  4. Once we have received your confirmation and the bank transfer, we will send you an email containing consent to the disclosure of our address (PDF) — you’ll use it to register the company. 
  5. Register the company and wait for it to be entered in the register. The contract is deemed to commence on the date of entry.
  6. Once you have submitted your details, please contact us and provide your NIP and REGON numbers – we will draw up a contract and a pro forma invoice, and once payment has been made, we will issue a VAT invoice.

Foundations and associations come into existence upon entry in the National Court Register (KRS) – from that point onwards, they may enter into contracts. We enter into the office lease agreement after entry in the KRS. The process is carried out online via 100%. 

  1. Select a location and the status „New business” → foundation / association. Fill in the details and submit the form.
  2. Make a verification transfer of 1 grosz from the founder’s personal account — it must not come from an account held in the name of our office. The account number can be found in the tab Contact. 
  3. Confirm via text message — reply „YES” to the message we’ll send you. 
  4. Once we have received your confirmation and the bank transfer, we will send you an email containing consent to the disclosure of our address (PDF) — you will use it to register your business. 
  5. Register your foundation or association and wait for it to be entered in the National Court Register (KRS) (this can take from a few weeks to a few months). The start date of the contract is calculated from the date of entry.
  6. Once you have submitted your details, please contact us and provide your NIP and REGON numbers — we will draw up a contract and a pro forma invoice, and once payment has been made, we will issue a VAT invoice.

Is your business already registered? You can sign the contract straight away, online at 100%. 

  1. Select a location and the status „Existing business”, then choose the type of business. Enter Tax Identification Number (NIP) and National Business Registry Number (REGON) (compulsory fields), and in the field Company name Please provide the name only, without specifying the legal form. As the representative, please specify the authorised person: the owner (sole trader), a member of the management board, the chairman, a proxy or authorised signatory (company), or a person authorised to represent the organisation (foundation/association) — if the authority to act is not explicitly stated in the KRS/CEIDG, please attach a power of attorney (PDF). Please provide your correspondence address (your actual address, not an office address), the start date of the contract (no earlier than today) and the billing address. Submit the form.

  3. Confirm that you wish to enter into the contract by text message — reply to the message we will send you.
  4. Once both steps have been completed, we will generate a contract and a pro forma invoice. Once payment has been made, you will be granted access and receive a full set of information to get you started.

No – you sign the contract online. We do not enter into contracts by post or at our office. We operate entirely online at 100%.

Verification transfer For a fee of 1 grosz (0.01 zł), it verifies the details of the individual or company entering into a contract with us — payment of this fee is a prerequisite for the conclusion of the contract. 

We have deliberately chosen not to integrate this payment method with payment gateways, as is common with online shops — we want to avoid any suspicion that this is an attempt to defraud people. You’ll find the account number in the tab Contact — You can make a bank transfer in whichever way is most convenient for you: via your bank’s app, website, at a branch or by telephone. 

The bank transfer must originate from the account of the individual or company entering into the contract — this may be a personal account (e.g. where the company is not yet registered or does not have a business account), a business account held by an existing company, or the account of an authorised representative, if they are entering into the contract on behalf of the company. 

We do not accept bank transfers from accounts registered at our address — this applies to situations where a company has been registered with us without a contract and has subsequently opened a bank account, using our address as its own. Nor do we accept transfers via third-party organisations that do not verify identity before transferring funds (e.g. Poczta Polska) or before opening an account. 

If you do not have a bank account, we will unfortunately have to cancel the contract — a valid verification transfer is essential for us to begin providing the service.

You can pay for the contract itself from any account – a personal account, a business account, a third-party account or another company’s account. Unlike with a verification transfer, you have complete freedom here.

You can find a template contract here. The terms and conditions are standard and do not differ significantly from those of other providers – the difference is that we make the contract available for you to review before you sign it, with no time pressure.

This is a template – there’s no need to print it, sign it or send it back to us.

We do not enter into contracts with a backdated date – this is unlawful and may have serious consequences.

Sign a contract straight away – yes, it’s possible. The system operates online 24/7, so you can sign it even at 10.00 pm or at the weekend, without any unnecessary paperwork or the need to contact us in real time.

This doesn’t mean skipping any steps – you still go through the standard process: you fill in the form, make a verification transfer and confirm via text message. The steps vary depending on whether you have an existing business, are setting up a new company, or are setting up a new sole trader business (JDG) – see the „How to complete the form” section above for details.

Please send us confirmation of the verification transfer to biuro@biuro31.pl — this will speed up the process. 

Once you have completed the formalities, you can start using the address straight away. You will receive the contract (dated on the day it was actually concluded online) and the pro forma invoice for payment by the next working day at the latest.

We offer a contract for 3, 6, 12 and 12 months, payable in advance for the year. Please read a detailed proposal i price list. 

No. You pay for the service as a one-off payment, in advance for the whole year. We’ve decided to do it this way because instalment payments create extra work – reminders, keeping track of payments, and additional invoices. A one-off payment reduces this paperwork and allows us to maintain a simple, automated service process.

You can use the address from the date the contract comes into effect, as specified in the contract — this is not the same as the date on which it was concluded. The contract can be concluded earlier, but its effective date can be set for a future date, depending on the customer’s choice. If the date of conclusion and the effective date are the same day, you can start using the address straight away. 

You have 7 days to pay for the service (the deadline is shown on the pro forma invoice). You can use the address — for example, to register your business or change your company’s address — even before you’ve paid the invoice. 

Access to the premises and the actual provision of the service will only commence once the pro forma invoice has been paid. Therefore, if you receive any post before that date, you will only be able to collect it once you have paid for the service. 

No. We assume that if you wish to continue, you’ll get in touch with us yourself — we don’t tie customers into long-term contracts. Before the contract ends, the system sends email reminders with instructions on how to sign a new contract for the following year, and on the final day — a text message confirming the end of the contract. If you ignore the reminders, the contract simply ends, with no additional charges. 

Yes, we distinguish between several situations here. A consumer — that is, a natural person, including a sole trader — who has entered into a distance contract may withdraw from it within 14 days without giving any reason and at no extra cost. 

After this date, the contract may still be terminated at any time, but without any refund, either in full or in part.
