What Documents Do You Need to Open a Business Bank Account?

The UK rule is the same at every bank: a government photo ID, a proof of address dated within three months, and the right paperwork for your business structure. Get those three right and most applications go through cleanly.

We’ve broken the checklist down by business type because the load is wildly different. A sole trader can be open on Starling in ten minutes. A limited company with three shareholders applying to NatWest can wait four weeks.

We checked the document lists against UK Finance guidance, the Money Laundering Regulations 2017, and the live application flows at Starling, Tide, HSBC, Barclays, and NatWest in May 2026. What you’ll read below reflects what banks actually ask for, not what their FAQ pages suggest.

What Documents You Need to Open a Business Bank Account: At a Glance

Every UK applicant needs two personal documents: photo ID and proof of address. That covers the MLR 2017 baseline. What you add on top depends on whether you trade as a sole trader, a limited company, a partnership, or an LLP.

Sole traders stop at two documents. Limited companies and LLPs add Companies House records plus ID for every director and anyone holding 25%+ of the shares. Partnerships need ID and address for every partner, with no de minimis threshold.

That’s the simplest case. If your structure is more complex, the list grows.

Got the documents in front of you now and trading as a sole trader? You can be banking by lunchtime. A three-director limited company with a non-UK-resident shareholder should plan for a longer week.

We’ll explain each row below.

Business Bank Account Documents for Sole Traders

Sole traders have the lightest paperwork. There’s no legal separation between you and the business, so the bank only needs to verify you, not a separate company entity.

You’ll need a valid passport or UK photocard driving licence, one proof of address dated within three months, and your National Insurance number. Some banks also ask for your UTR — the 10-digit HMRC reference you got when you registered for self-assessment.

That’s the simplest case. No certificate. No shareholders. No PSC schedule.

On the morning you sit down to apply, have your ID, a recent utility bill, your NI number, and your UTR if you have one. Tide and Starling will then ask for a biometric selfie — a short live video matched against your ID photo.

A note on home addresses: if you work from home, the bank uses your residential address as both the personal proof of address and the business trading address. That’s normal. You don’t need separate documents for each.

Expired ID is an immediate rejection. We’ve watched applicants try to push through a passport that runs out the same week — the bank’s system blocks it before a human even looks. Use a document with at least six months left on it.

Business Bank Account Documents for Limited Companies

Limited companies need everything a sole trader provides, plus documents that prove the company exists and identify the people behind it. The bank has to satisfy two checks: the company is real, and you’re entitled to open an account in its name.

For the company itself, you’ll need the certificate of incorporation, your eight-digit Companies House registration number, your registered office address as it appears on the Companies House record, and your SIC code. High street banks sometimes ask for your Memorandum and Articles of Association too.

For the people, every director needs personal ID and proof of address. So does every Person of Significant Control — that’s anyone holding 25%+ of the shares or voting rights, or who otherwise controls the company.

That last point is where most limited company applications stall. If you have a silent shareholder with 30% and you don’t list them as a PSC, the application is escalated for manual review.

PSCs are the trip-wire. Miss one and the clock resets.

Digital banks verify most of the company side through the Companies House API in real time. You type the company number, the system pulls the record, you confirm the details. That’s how Tide and Starling open a single-director limited company in under an hour.

High street banks frequently want signed, dated copies of the Memorandum and Articles, especially if your structure has share classes or unusual voting arrangements. If you incorporated through a formation agent, those documents will be in the welcome pack they sent you.

Before you apply, check that the registered office address on Companies House matches every document you’re going to upload. Mismatches are the leading cause of delays we see in the provider application logs we’ve been shown.

On the morning you click submit, pull up your Companies House record on screen and have it open next to the application. That way you can copy the exact SIC code and address rather than typing from memory. Five minutes, saves a week.

Business Bank Account Documents for Partnerships and LLPs

Partnerships and LLPs sit between sole traders and limited companies for documentation. The volume depends on whether you’re a registered LLP or an unregistered general partnership.

A general partnership has no Companies House record. You’ll provide a copy of your partnership agreement or deed, personal ID and proof of address for every partner, and a description of the business and expected turnover. There’s no 25% threshold — every partner is checked.

An LLP is registered at Companies House. You’ll need the certificate of incorporation, the LLP agreement, and ID plus proof of address for every designated member. Any member with 25%+ economic interest goes through a full PSC-level check.

Scottish partnerships are a quirk worth flagging. Because Scottish partnerships have separate legal personality, banks treat them more like companies than partnerships. Expect to provide a corporate-style document set.

Collecting documents from multiple people is the main friction point. A week before you start, the partner running the application should send everyone a clear list. Chasing missing proof-of-address documents mid-application is the single biggest delay we see in partnership openings.

What Counts as Proof of Identity for a Business Bank Account

Four types of ID are accepted across the UK market: a valid passport, a UK photocard driving licence (full or provisional), an EU national identity card, or a biometric residence permit.

That’s the list. Paper driving licences are not accepted. We checked this against every bank in our coverage in May 2026.

A few practical points. Your passport must be valid — expired passports are rejected automatically, even by a single day. If yours expires within six months, renew it before you apply. You don’t want to be reopening the application halfway through.

EU national ID cards are accepted by digital banks and most high street banks. Foreign passports outside the EU and UK are accepted but will trigger enhanced checks — we cover those below.

A biometric residence permit works the same way as a passport for identification, with one extra step: digital banks scan the NFC chip on the card to confirm the document is genuine. Have a phone with NFC enabled when you apply.

What Counts as Proof of Address for a Business Bank Account

Proof of address has to be dated within three months. The exception is a council tax bill, which is usually accepted for the full financial year.

Accepted documents are utility bills (gas, electricity, water, or landline phone), bank or building society statements, credit card statements, council tax bills, and HMRC correspondence such as a tax return acknowledgement.

Mobile phone bills are not accepted. We’ve watched this catch out applicants who don’t have a landline — banks treat mobile contracts as too easy to set up under a false name.

PDF documents are fine. Starling, Tide, Monzo, Revolut, and ANNA all accept digital statements uploaded straight from your online banking. HSBC, Barclays, and NatWest now accept digital uploads too on most application flows, though branch-based applications occasionally still want printed originals.

When you’re gathering paperwork, log into your personal current account and download last month’s statement as a PDF. That’s the fastest route. If you only get paper statements, photograph a utility bill in good light against a plain background — corners visible, all four edges in frame.

Digital vs High Street Business Bank Account: How Document Requirements Differ

The document list looks similar across digital and high street banks. The difference is in how the documents are verified, and that drives the speed gap.

Digital banks use three technical shortcuts the traditional banks don’t. An Open Banking identity ping confirms you hold an existing UK bank account without anyone reading a paper statement. The Companies House API verifies incorporation documents in real time. A biometric selfie does a liveness check against your ID photo.

That last bit removes the need for certified copies entirely.

High street banks still rely on signed mandates, branch visits, and manual review. A sole trader on Starling can finish the application on a smartphone in under ten minutes.

The same sole trader on Lloyds waits five to seven working days and may need a branch visit.

That’s the practical gap. The document list is barely different. The verification stack is.

High street wins on breadth of services — overdrafts, lending, FX, branch access. Digital wins on speed and document-handling. Need the account open this week? Digital is the safer bet.

Enhanced Due Diligence: When Your Business Bank Account Application Needs More

Enhanced due diligence (EDD) is the extra review banks must run under Regulation 33 of the Money Laundering Regulations 2017 when an application carries elevated risk. It doesn’t mean rejection. It means a longer process — two to eight weeks on average.

Five common triggers push you into EDD. A director or beneficial owner who is a Politically Exposed Person (PEP) or a close family member of one. Counterparties based in a FATF grey-list or blacklisted country. High volumes of cash — hospitality, retail, scrap metal.

A director who is non-UK-resident and can’t be biometrically verified locally. Or a business model that itself presents elevated money laundering risk. Any one of these is enough.

When EDD kicks in, expect the bank to ask for source of funds documentation, source of wealth records for high-value accounts, a more detailed beneficial ownership map, and sometimes professional references from your accountant or solicitor.

If you know you’ll trigger EDD — a non-resident director, say — gather the additional documents before you apply. Audited accounts, recent business bank statements from your previous account, and a one-page corporate structure diagram will all be asked for. Having them ready cuts review time by weeks.

How to Get Your Business Bank Account Application Approved First Time

Six rejection reasons account for the bulk of failed first applications. We pulled this list from UK Finance guidance and provider rejection logs. Fix these before you apply, not after.

1. Document mismatch. The registered office address on your Companies House record doesn’t match the address on your application or your proof-of-address documents. Update Companies House first, wait for the change to publish, then apply.
2. Expired ID. Use a passport or driving licence with at least six months remaining. A document expiring next week is treated as expired today by most automated systems.
3. SIC code mismatch. The industry code on Companies House doesn’t match what you wrote in the business description on the application. Pick the closest matching SIC code and update Companies House before applying.
4. Missing PSC. Any shareholder with 25%+ economic interest or voting rights must be listed and verified. Forgetting a silent partner is the single most common limited-company rejection trigger.
5. Insufficient trading history. High street startup accounts often want at least three months of trading. Digital banks accept day-zero companies. Pick the channel that matches your situation.
6. Unclear source of funds. If your initial deposit is over £5,000, the bank will want evidence of where it came from — payslips, a sale contract, a loan agreement, or transfer records from a previous business account.

The pattern across all six is the same: information consistency. Banks aren’t looking for tricks. They’re looking for a clean match between what you say, what Companies House says, and what your supporting documents say.

Before you click submit, do one final pass. Open your Companies House record, your draft application, and your uploaded documents side by side. Confirm the company name, address, director names, and SIC code are identical across all three.

That five-minute check catches most rejections.
