In practice, yes — a limited company needs its own business bank account, and the reason sits at the heart of why you went limited. A limited company is a separate legal entity: its money is legally the company's, not yours, even if you own every share and are the only director. Run the company's income and expenses through your personal account and you blur that line — the bookkeeping gets messy, and anything you take out is harder to evidence as a salary, a dividend or a director's loan. There's no single gov.uk line saying "you must, by law, hold a business account", but it's the practical consequence of the company being separate from you, and banks won't let a company trade through a personal account anyway. A sole trader is different: legally they can use a personal account, because they and the business are the same person. For a company, a dedicated account isn't a nice-to-have — it's how you keep the separation real.
General guidance for UK directors, not personal advice. We help you decide and connect you with a partner accountant — we don't open the account for you.
Why does a limited company need its own account?
The whole point of incorporating is that the company becomes a person in its own right — it can own assets, owe money and be sued in its own name, separately from you. When you formed it, you and the company stopped being the same legal entity (gov.uk). That principle has a very ordinary, everyday consequence: the money the company earns belongs to the company, and it should sit in an account in the company's name.
Keep company money in a personal account and three things go wrong. First, your books stop being clean — every personal coffee and every client invoice land in the same place, and someone (probably your accountant) has to untangle them later. Second, you lose the clear audit trail Companies House and HMRC expect a company to keep (gov.uk). Third, and most importantly for tax, you can no longer cleanly show what you've taken out and why — which matters enormously once dividends and director's loans enter the picture.
There's a softer reason too: a business account in the company's name looks like what it is. Clients paying a registered company expect to pay the company, not "R. Vieira", and a company-named account quietly signals you're set up properly.
Here's the honest, precise answer, because a lot of pages get this slightly wrong. There is no single statute that says "every limited company must hold a business bank account". So strictly, it isn't a standalone legal "must" in the way that, say, filing a confirmation statement is.
But that's not the same as "you can skip it". Two things make a business account a practical requirement for a company. One, the separate-legal-entity rule means the company's money has to be kept as the company's money — and the only sensible way to do that is an account in the company's name. Two, banks themselves require a limited company to open a business account rather than run trading through a personal one; a personal account's terms generally don't permit business use by a separate legal entity. Put together, the result is the same as a hard rule: for a company, you need a business account.
This is exactly where a sole trader differs. A sole trader and their business are legally one and the same, so HMRC doesn't require a separate account and they can legally use a personal one — though keeping a dedicated account is still sensible for clean records. If you're weighing the structures, our guide on how to set up a limited company walks through what changes the moment you incorporate.
A quick way to see the contrast:
Sole trader
Limited company
Legal status
You and the business are the same
Separate legal entity
Whose money is it?
Yours
The company's
Personal account allowed?
Yes (legally)
No — needs a business account
The table is the short version; the line that matters is the middle row. Once the money is legally the company's, it has to live somewhere that proves it.
What do you need to open a business account?
Opening a company account is usually quick, and the requirements are broadly consistent whoever you bank with. You'll typically be asked for your certificate of incorporation, your company details (registered name, number and registered office), and identification for the directors and any people with significant control — banks run anti-money-laundering and identity checks as standard. Most will also ask what the company does and your expected turnover, so they can set the account up correctly.
We deliberately won't tell you which provider to use or what it costs each month — the comparison sites and the banks themselves are already doing that, and our value to you is the impartial bit. What we'd say is to open the account early, ideally as soon as the company is formed, so that the very first pound the company earns lands in the right place rather than needing to be reclassified later. If you bought an off-the-shelf (ready-made) company to start trading fast, the bank account is the step to sort straight after the transfer of control.
What about director's loans and keeping money separate?
This is where the separation earns its keep. Because the company's money is the company's, you can't simply move funds from the business account into your own pocket whenever you like. When you do take money out, it has to be classified — as salary (run through payroll), as a dividend (paid from post-tax profit, with the paperwork to match), or, if it's none of those, as a director's loan.
A director's loan is money you've taken from the company that isn't salary, dividend or a repayment of money you put in — and it carries real tax consequences if it's overdrawn at the year-end and not repaid in time. Mixing company and personal funds in one account is precisely how directors end up with an accidental overdrawn loan they didn't realise they'd created. Keep the company's money in the company's account, draw deliberately, and the picture stays clean. Our explainer on how director's loans work covers the tax traps in full.
The first admin step we point new directors to after incorporation is a company bank account — it's the cleanest way to keep the company's money provably separate from your own, and it makes everything downstream, from dividends to your year-end accounts, far simpler. When you're ready to get the rest set up properly, the accountancy support we match you with picks up from there. If you're also working out what you can run through the business, our guide on limited company expenses you can claim pairs naturally with this one.
Keep the company's money the company's
Going limited is, at bottom, a decision to make your business a separate legal person — and a business bank account is simply that decision made concrete. It isn't a box-tick for the sake of it; it's the line that keeps your salary, your dividends and any director's loan provable, your books clean and your year-end painless. Sort the account early, keep the two purses apart, and you've removed most of the admin headaches a new director runs into.

There's no single statute that says a company must hold one, so it isn't a standalone legal "must" in the way filing a confirmation statement is.

You shouldn't. The company's income and expenses are legally the company's, not yours, so they belong in an account in the company's name.

Can a sole trader use a personal account?
Yes — legally a sole trader can, because they and the business are the same person, so HMRC doesn't require a separate account. A dedicated account is still sensible for clean records, but it isn't required the way it effectively is for a limited company.
What happens if I take money out of the company account for personal use?
It has to be classified as salary, a dividend, or a director's loan — you can't simply treat the company's money as your own. An overdrawn director's loan left unpaid at the year-end carries tax consequences, which is exactly why keeping the company's money in the company's account matters.
