If your business turns over under £6.5 million, you can usually follow a simplified evidence route to open a UK business current account. UK Finance and SmallBusiness.co.uk set out the identity, address and company documents most providers will accept, and having them ready avoids the common delays that derail applications. The documents include a single primary identity document, specific proofs of UK address with strict age limits, and business identifiers such as a Companies House registration number and directors' details. Work through the UK Finance checklist and the SmallBusiness.co.uk FAQ before you apply to speed the process.

1. Start with the one question that decides the route

Here is the simplest test that splits applicants. If your business is an existing enterprise with a clearly defined ownership structure, all owners operate in the UK, and turnover is below £6.5 million, most banks will consider you for the simplified documentation route recommended by UK Finance. If any of those three conditions fail, you should expect fuller due diligence and additional paperwork.

That matters because the simplified route isn't a separate product. It's an assessment standard banks use when deciding whether to accept a short, predictable set of documents. UK Finance and SmallBusiness.co.uk both stress that the eligibility rule is a gatekeeper: meet it and you short-circuit much of the paperwork; fail it and you will usually be asked for more evidence.

Worked example: you are a limited company trading for two years, with two directors who both live and work in the UK and annual turnover of £420,000. You meet the conditions and should prepare the simplified evidence set before applying.

2. Gather the primary identity document

Most providers will ask for one primary Identity document. The guidance lists acceptable documents explicitly. Acceptable options are a full and valid UK or foreign passport, a national identity photocard, a full UK paper driving licence, or a full UK or foreign photocard driving licence issued by an EU or EEA member state.

Have the original to hand for inspection or ready to upload when the application is completed online.

Make no assumptions about photocopies. Banks expect originals or institution-issued PDFs. That reduces follow-up requests and is a frequent reason for delay.

Worked example: if a director holds a Spanish photocard driving licence, that licence is listed as acceptable under the guidance, so include it alongside other identity evidence when you apply.

3. Assemble proof of UK address with the correct recency and format

Address evidence is where applications stall. The guidance specifies a short list of acceptable Proofs of address and the maximum age for each. Providers will typically accept a full UK driving licence, a full UK or foreign photocard driving licence issued by an EU or EEA state, a UK or foreign bank or credit-card statement that's less than three months old and not printed from the internet, a UK mortgage statement less than 12 months old and not printed from the internet, a council tax bill, payment book or exemption certificate less than 12 months old, or a letter or bill from a utility company less than six months old.

Two practical points matter. First, banks explicitly recommend avoiding mobile phone bills as primary evidence. Second, statements and mortgage documents printed from internet pages aren't acceptable; providers expect original paper statements or PDFs issued by the institution.

Worked example: you live in a rented flat with a council tax certificate dated seven months ago. That's older than the one-year limit for council tax evidence, so obtain a newer document or use a recent bank statement that meets the three-month rule.

4. Collect business identity and control details

If your business is incorporated, the guidance expects you to supply a Companies House registration number. Banks will use that number, together with directors' names and addresses, to verify company status and control. Providers also ask for succinct figures for turnover, tax identifiers and details of capital or funding available to the business.

Mastheads

For every company director or partner, have full name, date of birth, current address and National Insurance number ready. These data points are routine inputs to anti-money-laundering screening and identity checks.

Worked example: a sole director of a registered limited company should include the Companies House number, the company turnover figure used for the last accounting period, their National Insurance number and current address when prompted on the application form.

The guidance doesn't recommend particular banks or tariffs, but it does set the expectation that most business current account providers will ask for the documents outlined above. After you assemble your paperwork, consult provider product pages and their FAQs to check for any deviations from the standard list.

Confirm whether the provider requires in-branch verification or allows fully digital onboarding, what file size limits they impose for scanned documents, and whether they accept institution-issued PDFs. SmallBusiness.co.uk suggests using its comparison material and frequently asked questions to narrow options and confirm these details before you begin an application.

Worked example: one provider might accept a scanned PDF bank statement up to 5MB and allow a remote identity check, while another will require in-branch sighting of originals. Check the provider FAQ so you know which process applies.

With the right documents prepared, submission is straightforward. UK Finance emphasises that having correctly dated evidence ready reduces delays and the likelihood of banks requesting supplementary documents. Banks often come back for extra material when submitted evidence is missing, older than the permitted window, or printed from the internet.

Be responsive to follow-up requests. A quick reply to an additional verification question normally shortens the onboarding timeline. If a requested statement is too old, obtain a newer one rather than hoping the bank will accept the older copy.

Worked example: after submitting an online application you are asked to provide a mortgage statement less than 12 months old. If your last statement is 14 months old, request an updated statement from your mortgage provider and upload it promptly to avoid a hold on your application.

The guidance highlights a small number of recurring issues. First, the turnover threshold and residency conditions are the main gatekeepers. If turnover exceeds £6.5 million, your business is newly formed without trading history, or owners live outside the UK, expect fuller document requirements and longer checks.

Second, timing and document recency matter. Address documents have strict age limits and bank or mortgage statements must not be printed internet copies.

If a statement is older than the permitted window, obtain a newer one before you apply. If you lack a listed document type, check the provider FAQ or the UK Finance guidance for acceptable alternatives before you submit.

Third, Companies House details and director identification are commonly requested together. Providers will typically cross-check the Companies House registration number with directors' names and addresses. If you are a sole trader without a Companies House number, expect the provider to rely more heavily on personal identity and proof of business activity.

Basically, finally, there are technical variations between providers that the guidance doesn't harmonise. You should expect variation in allowable documents, online upload limits and onboarding turnaround times. SmallBusiness.co.uk recommends consulting provider FAQs to resolve these differences before you start.

First, run your business through the eligibility test. Confirm that you meet the three criteria UK Finance sets out: existing business, turnover below £6.5 million, all owners operating in the UK. Second, use the checklist below to assemble the standard evidence set before you open an application. Third, consult selected providers' product pages and FAQs to confirm any supplementary requirements.

Standard evidence checklist, presented as short actions you can tick off. First, one primary identity document: full UK or foreign passport, national identity photocard, full UK paper driving licence, or photocard driving licence issued by an EU or EEA state. Second, proof of UK address that meets the recency rules: bank or credit-card statement less than three months old, mortgage statement less than 12 months old, council tax bill less than 12 months old, or utility bill less than six months old. Third, business identifiers: Companies House registration number if incorporated, turnover figures, tax identifiers, and for each director or partner, name, date of birth, address and National Insurance number.

Work through the UK Finance checklist and consult the SmallBusiness.co.uk FAQ to prepare before you begin the provider application. That's the single, practical action the guidance recommends to avoid delays.
