What is an address verification letter and how do you get one

What is an address verification letter?

If you have ever applied for a business bank account, you have probably hit a point in the application where the bank asks for proof of your business address. For many business owners, this is where things grind to a halt.

An address verification letter is a formal document that confirms a business is associated with a specific address. Banks use it as part of their know your customer (KYC) checks, which they are legally required to carry out before opening an account. Unlike a personal address check, which might accept a utility bill or bank statement, a business address check often needs something more specific.

In this post, we cover what an address verification letter actually is, why banks ask for it, what it needs to contain to be accepted, and how a letter from a virtual address provider differs from other documents you might already have.

Whether you are forming a new limited company or switching banks, understanding this document will save you a lot of back-and-forth.

Why banks require proof of address for your business

Banks in the UK operate under strict anti-money laundering (AML) regulations. Before they open a business account, they must verify who owns the business and where it operates from. Bank address verification is one part of that process.

For sole traders, the address check is often straightforward. A recent utility bill or HMRC correspondence in your name may be enough. For limited companies, it is more complicated. Companies House lists your registered office address publicly, but banks also want to confirm that the address on your application matches your actual operational or correspondence address.

This matters because some business owners use their home address as their registered office, while others use a separate correspondence address for day-to-day post. Banks want to understand which address is which, and they want documented confirmation that you have a legitimate connection to it.

If your business uses a virtual address or registered office service, you will likely be asked to provide a registered address letter bank can accept, issued by your address provider. Without this, your application may be delayed or declined.

What an address verification letter must contain

Not all letters are accepted by all banks. Before submitting anything, it is worth checking your bank's specific requirements. That said, most banks expect the following information to be present in an address verification letter:

• The full legal name of your business, including "Limited" or "Ltd" if applicable
• Your registered company number
• The full address being verified, including postcode
• The date the letter was issued
• The name and contact details of the company issuing the letter
• A signature or official stamp from an authorised representative

Some banks also ask for the letter to be issued on headed paper and sent within the last three months. Older letters are often rejected, so it is worth requesting a fresh one if yours is out of date.

If you are providing a letter from a registered office or virtual address provider, some banks will also want to see your signed service agreement or licence to use the address. It is worth asking your bank exactly what they need before you make a request to your provider, so you can get everything in one go.

Virtual address letter versus a utility bill: what is the difference?

This is a question that trips up a lot of new business owners. When a bank asks for proof of address for business, you might assume a utility bill will do the job. In some cases it will, but there are important differences worth understanding.

A utility bill shows that someone pays for energy or water at a given address. It is a reasonable indicator of residential or operational presence. However, a limited company's registered address is a legal designation, not necessarily a place where someone pays bills. If your registered office is a virtual address, there will be no utility bill in your company's name at that address.

A letter from a virtual address provider, on the other hand, confirms that you have a formal agreement to use that address for your business. It is a contractual document rather than a billing document. Most major UK banks accept letters from reputable address providers, particularly for registered office use, though some challenger banks may have stricter requirements.

The key thing to remember is that a utility bill and an address verification letter are solving the same problem (confirming your connection to an address) but in different ways. Your bank may accept either, both, or have a specific preference. When in doubt, call the bank's business account team before you apply.

Summary: what to do next

An address verification letter is a formal document confirming your business's connection to a specific address. Banks ask for it as part of their legal obligation to verify business customers. To be accepted, the letter should include your company name, registration number, full address, the issue date, and the contact details of the issuing party.

If you use a virtual or registered office address, your provider should be able to issue this letter on request. If you are using a home address or commercial property, a utility bill or HMRC correspondence may be sufficient, but always check with your bank first.

The clearest next step is to contact your bank's business account team, ask them exactly what they need for address verification, and then request the appropriate document from your address provider or prepare it yourself. Getting clarity upfront will save you time and prevent delays to your account opening.
