Does opening a business bank account affect your credit score?

Applying for a business bank account for your limited company usually has little or no effect on your personal credit score. Many banks do run a credit search on the directors, though, and some record it. Asking for an overdraft or credit card at the same time usually means a hard search, which other lenders can see.

We read the account-opening pages of 10 UK providers on 12 October 2026. Starling, Monzo, and Mettle say they run a soft search, and Tide says there's no hard credit check. The high-street banks say they run a credit check without saying which kind.

‍

It depends on whether the bank runs a soft or a hard search

A soft search doesn't affect your credit score, and other lenders can't see it. A hard search is recorded on your file and can lower your score for a while. Banks usually run one when you ask for credit, such as an overdraft or a credit card.

A plain current account isn't credit, so it rarely needs a hard search. An overdraft is borrowing, so the bank assesses it like any other credit application. If you plan to use an overdraft, see how a business overdraft can affect your personal credit before you tick the box.

‍

Banks can check your personal file, the company's file, or both

A limited company has its own credit file, separate from the directors' personal files. Banks often check both, especially when the company is a start-up or has fewer than three directors.

Barclays says that for 'a start-up or a small business with less than three directors, lenders may look at both your personal and business credit scores together'. HSBC UK checks 'both your business and the individual owners' when you borrow.

Your personal file usually comes into it in three situations:

• The bank confirms your identity and address as a director, usually with a soft search.
• The company is new and its own file is thin, so the bank looks at the directors' history.
• You ask for credit backed by a personal guarantee, so the bank checks the director who signs it.

The company's file can carry a hard search too. Monzo, for example, runs a hard search on the company's file when a limited company applies for an overdraft, and a soft search on the director. The steps for opening a limited company bank account are the same either way. To see what lenders see on the company's side, check your company's credit score.

High-street banks run a credit check, app-based banks mostly a soft search

On 12 October 2026, Barclays, HSBC UK, Lloyds Bank, NatWest, and Santander all said they run a credit check when you apply, and only Santander said the search is recorded. Starling, Monzo, and Mettle said soft, and Tide said there's no hard credit check.

Checked on each provider's own website on 12 October 2026. Policies change, so check with the bank before you apply.

'Not stated' means we couldn't find it on the provider's own site, not that it doesn't happen. If it matters to you, ask the bank before you apply: 'Will this application leave a hard search on my file or the company's?'

A hard search stays on your file for about a year

Experian says most hard searches stay on your credit report for 12 months. One hard search matters less than several close together: too many in a short period can affect your score for six months.

That's why the order you do things in matters. If you're also planning a mortgage, a car loan, or business borrowing, open the account without credit features first, and apply for credit later once you need it.

‍

You can usually still open an account with bad credit

Usually, yes. A poor personal credit history makes high-street banks and credit features harder to get, but providers that run only a soft search, or no hard check, are often still open to you.

To give your application the best chance:

• Apply for a basic account first, and add an overdraft or card later once the account has some history.
• Leave out credit features you don't need, so the bank has no reason to run a hard search.
• Apply to one bank at a time, starting with a provider that says it runs a soft search.
• Have the company's registration details, ID for each director, and recent accounts or statements ready.
• Check your personal file and the company's file before you apply, and ask the agency to correct anything wrong.

Be honest about past problems if the bank asks. If one bank says no, ask what tipped it before you apply elsewhere. If you want to weigh up fees and features, compare business bank accounts.

How lenders like iwoca use your business account

When a company applies to iwoca, its business bank statements, shared through Open Banking or uploaded, help us understand its cash flow. Checking your eligibility runs a soft search. A hard search follows only if you accept a loan.

What a lender reads in the account history:

• How regular the money coming in is, and where it comes from.
• How much stays in the account through the month, including the lowest points.
• How the money going out compares with what comes in.

To keep an eye on the company's side, iwoca Credit Compass shows your company's Equifax business credit score free, with four more scores and an overall health score. Those scores cover loan and credit history, financial performance, and the Companies House record, and they show what lenders like iwoca see. Credit Compass refreshes every month, suggests areas to improve, and lets you know as soon as an issue becomes visible. You can also connect your business account through Open Banking for more up-to-date turnover and balance information.

'It's definitely a useful resource for keeping tabs on where your business stands - and it's free, so why not use it?' says Olusegun Shiroye, founder of Bolfis Limited, on the launch of Credit Compass in March 2026.

If a bank turns down the overdraft but the account is open, an iwoca business loan is one alternative for UK limited companies. You can borrow £1,000 to £1m, for one day to five years, and many get an instant decision, or a decision within 24 hours. You only pay interest on what you draw, with no early repayment fees, though borrowing for more than 12 months may add a fee, typically 5% for 13 to 24 months and 6% for longer.

Frequently asked questions

These answers assume a UK limited company applying for a business current account.

‍

Does a rejected application hurt my credit score?

The search is what can affect your score, not the answer. A hard search stays on your file whether the bank says yes or no, and a soft search has no effect. Ask the bank why it said no, fix what you can, and try a provider that runs only a soft search.

‍

Does applying to several banks at once hurt my credit?

Several soft searches don't, because lenders can't see them. Several hard searches close together can affect your score, so apply to one bank at a time if it runs hard searches.

‍

Does switching business bank account affect my credit score?

Switching works like opening a new account: what matters is the search the new bank runs.

The Current Account Switch Service is open to businesses with an annual turnover up to £6.5 million and fewer than 50 employees, and it moves your payments across for you. See how to switch business bank account.

‍

Does a business bank account help build business credit?

It can. Nine banks designated by HM Treasury share current account information on smaller businesses (turnover under £25 million) with designated credit reference agencies, with the business's permission. That means a well-run account can count in the company's favour.

Open the business account before you need to borrow, and keep company money in it. Find out how to build your business credit score.

Will checking my company's credit score affect it?

No. Checking your own score is a soft search. Credit Compass shows your company's Equifax business credit score free and refreshes it every month.
