Opening a business bank account: what actually holds it up

There is a particular week in the life of a new company where nothing can happen. The company exists, the first customer is ready to pay, and there is nowhere for the money to go, because the bank account application has been sitting in review for nine days with no explanation and no way to chase it.

Almost none of these cases are credit decisions. A plain business current account with no overdraft involves no lending, so nobody is scoring your business. What is happening is an identity check, and identity checks fail on inconsistency rather than on risk.

What the bank is actually doing

Under the Money Laundering Regulations 2017 a bank has to verify who the customer is, who ultimately owns and controls it, and what it intends to do. In practice that means four things: verifying the company against the public register, verifying every director and every person with significant control — anyone holding more than 25% of the shares or voting rights, or otherwise exercising control — understanding the intended activity well enough to spot when it later changes, and forming a view on the expected pattern of money going through the account.

That last point is the one people underestimate. The figures you give at application — monthly turnover, average transaction size, how much cash, which countries — become the baseline your account is monitored against for years. Guessing wildly at that stage is the most common cause of a payment being held six months later.

A business account application is not a credit test. It is an identity test, and identity tests fail on inconsistency, not on risk.

The five mismatches that stall applications

First, the application does not match the public record. A registered office updated on the application but not at Companies House, a director's name given as Danny when the register says Daniel, a date of birth keyed a digit out. The bank's system compares the two automatically and a difference it cannot resolve goes to manual review, where it queues.

Second, the persons with significant control register is missing, wrong, or lists a corporate shareholder with no ownership chain behind it. If your company is owned by another company, expect to evidence ownership all the way up to the human beings at the top.

Third, the SIC code. Plenty of companies are incorporated with a catch-all code because the formation agent's dropdown made it easy — 82990 for other business support services, or 64999 for financial intermediation not elsewhere classified. The second of those puts a builder or a marketing agency into a category the onboarding team reads as financial services, which is exactly the wrong queue to be in. Pick the code that actually describes what you sell, and change it at the next confirmation statement if it is wrong.

Fourth, the address story does not hold together. A registered office at a formation agent, a trading address at home, and no document tying you to either is a common and entirely innocent position for a new business. It still needs evidence: a utility bill, a council tax bill, a tenancy agreement, or a signed customer contract showing the trading address.

Fifth, cash. If you run a barber shop or a market stall, say so and give a realistic cash percentage. A cash-heavy trade that declares itself is ordinary. A cash-heavy trade discovered later, in an account that said it would receive card settlements only, is a review.

Have this ready before you start

Assemble the pack first and the application takes a morning instead of a fortnight. You need the company number and certificate of incorporation; the registered and trading addresses with proof for each; photo ID and proof of address for every director and every person with significant control; the ownership structure written out, including corporate shareholders and the ultimate owners behind them; a plain-English description of what the business does and who pays it; your expected monthly turnover, average transaction value and cash percentage; the countries you expect to send money to or receive it from; and the source of the opening deposit.

If you already trade, add two or three real customer invoices or a signed contract. Evidence that the business exists commercially resolves more manual reviews than any amount of explanation.

Bank or e-money institution — the difference that matters

A lot of small businesses now open with an app-based provider, and the accounts look identical. The protection behind them is not.

Money held with a UK-authorised bank is covered by the Financial Services Compensation Scheme up to £120,000 per eligible depositor per authorised firm, a limit that rose from £85,000 on 1 December 2025. Money held with an electronic money institution is not FSCS-protected at all. It is safeguarded — held in a segregated account at a separate bank, and intended to be returned to you if the provider fails — which is a real protection but a slower and weaker one, and it does not come with a compensation scheme behind it.

You can establish which you are dealing with in two minutes on the Financial Conduct Authority register, which states whether a firm is authorised as a bank or as an electronic money institution. Neither choice is wrong. Holding your entire tax reserve in the one without FSCS cover, without knowing that is what you have done, is. Where your business cash actually sits works through the limits, including the fact that a limited company gets its own £120,000 separate from your personal accounts.

What a freeze actually costs, in numbers

Imagine a company that told its bank at application it expected £15,000 a month, all UK, all by card and bank transfer. Eight months in it wins a good overseas client and a £14,000 payment arrives from a country the account has never seen. The account is restricted pending review, which takes ten working days.

Payroll of £9,200 is due on the 28th. The VAT payment of £6,400 is due on the 7th of the following month. Neither can be moved. Missing payroll costs goodwill you cannot price, and a late VAT payment adds a penalty and interest on top. The cost of the freeze is not the frozen money — that comes back. It is everything that could not be paid while it sat there.

Two habits prevent almost all of this. Tell the bank before the pattern changes, not after: a two-line message saying you have won an international client and expect payments from that country takes minutes. And never run the business through a single account.

The account structure worth setting up on day one

Open three, not one. A trading account that everything flows through. A tax account that receives a standing order after every VAT quarter and every payroll run, holding money that is not yours. And a reserve, ideally at a different institution, so that a review at one provider does not stop the business dead.

It costs nothing and it changes behaviour, because money you have physically moved is much harder to accidentally spend. If you are VAT registered, the moment your return is filed is the natural trigger for the transfer, and the same logic is what keeps January manageable for sole traders — why your January tax bill is bigger than you expected covers the payments on account version of the same trap.

One last thing worth doing while you are in the paperwork: check what your card acquiring actually costs, because it usually sits alongside the account and it is priced separately. Card processing fees and what they cost your margin has the arithmetic.

Common questions

Does a limited company legally need a separate business bank account?

In practical terms, yes. A limited company is a separate legal person and its money is not yours, so mixing it with personal spending makes the director's loan account impossible to track and your accounts expensive to prepare. There is no single statute that says the words, but company law duties around company property and the requirement to keep adequate accounting records make a separate account the only sensible way to comply. Sole traders are in a different position: legally you can use a personal account, but most personal account terms and conditions prohibit business use, so a bank can close the account if it notices.

Why do business bank account applications get declined or delayed?

Far more often on identity than on risk. The common causes are details that do not match Companies House, such as an address or a director's name or date of birth; a persons with significant control register that is missing, out of date, or hides a corporate ownership chain; a SIC code that puts an ordinary trade into a category the bank treats as high risk; no evidence linking the business to its trading address; and an unexplained cash-heavy model. Applications from companies bought off the shelf with a trading history nobody can explain also stall. Fixing the public record first and then reapplying usually resolves it faster than appealing.

Is money in a business bank account protected by the FSCS?

If the account is with a UK-authorised bank, building society or credit union, yes, up to £120,000 per eligible depositor per authorised firm, a limit that increased from £85,000 on 1 December 2025. A limited company or LLP is treated as a separate depositor from its owners, so the business gets its own limit alongside your personal one. Accounts provided by electronic money institutions are not FSCS-protected: your money is safeguarded in a segregated account instead, which is a genuine but weaker protection with no compensation scheme behind it. The Financial Conduct Authority register states which type of firm you are dealing with.

How long should opening a business account take, and can I speed it up?

A straightforward single-director UK company with clean public records is often approved the same day by app-based providers and within about a week by high street banks. Anything that needs manual review adds days rather than hours, and there is rarely a way to escalate once it is in the queue. The realistic way to speed it up is to remove the reasons for review before applying: correct the Companies House record, file an accurate persons with significant control register, choose a SIC code that describes the actual trade, and have identity documents, proof of trading address and realistic turnover and cash figures ready to submit at the first attempt.
