Business Current Accounts

What You Need to Know Before You Open One

If you’re starting or running a business in the UK, sorting out a business current account is one of those jobs that sits near the top of the list — right up there with registering with HMRC and getting your insurance in order. It’s not the most exciting part of running a business, but get it right and it makes everything else easier. Get it wrong, or put it off, and it can cause you real headaches down the line.

Here’s everything you need to know: what you’ll be asked for, why it’s worth having one, what it’ll cost you, and how to weigh it all up.

Do You Actually Need One?

This depends on how your business is set up.

  • Limited companies are legally required to have a business bank account. Your company is a separate legal entity from you, so its money has to be kept separate from your own.
  • Sole traders and partnerships aren’t legally required to have one — you could technically run everything through your personal account. But most banks’ terms and conditions don’t actually allow business use of a personal account, and mixing your finances makes bookkeeping, tax returns, and proving your income a lot harder than it needs to be.

In short: if you’re a limited company, it’s not optional. If you’re a sole trader, it’s optional but sensible.

What You’ll Need to Open One

Requirements vary a bit between providers, but you should expect to be asked for a mix of the following:

Personal identification

  • Passport or driving licence
  • Proof of your home address (a recent utility bill or bank statement)

Business documentation

  • Certificate of incorporation, if you’re a limited company
  • Your company registration number
  • Proof of your business address
  • Details of directors, partners, or anyone with significant control of the business
  • A list of anyone who’ll be authorised to sign on the account

Additional information some providers ask for

  • What your business does, and your expected turnover
  • Proof of trading history, if you’re already up and running
  • A financial statement or cash flow forecast, particularly for newer or higher-risk applications

Digital-only providers (like Starling, Tide, or Monzo) tend to verify your identity through the app rather than run a full credit check, which means a poor credit history or a CCJ doesn’t automatically rule you out. Traditional high street banks (Barclays, HSBC, NatWest, Lloyds) are more likely to credit-check you, and lending or overdraft facilities will always involve some form of credit assessment, whichever provider you go with.

How Long Does It Take?

  • Digital/challenger banks: Often minutes to a few hours, assuming your ID checks pass first time.
  • Traditional banks: Typically three to ten working days, and some still want a video call or branch visit before they’ll approve you.

If you need to start trading and invoicing quickly, that turnaround time is worth building into your decision.

The Benefits of Having One

It keeps your finances separate. This is the big one. Mixing personal and business money makes your bookkeeping messy, your tax return harder to complete accurately, and it makes it much tougher to prove to HMRC, lenders, or investors exactly how your business is performing.

It looks more professional. Invoices and payments from a named business account, rather than your personal one, give clients and suppliers more confidence you’re running things properly.

It builds a business credit history. Over time, this makes it easier to access business loans, overdrafts, or credit cards when you need them — separate from your personal credit file.

It often comes with useful tools. Most business accounts now bundle in invoicing software, expense categorisation, receipt scanning, and direct integration with accounting platforms like Xero, QuickBooks, or FreeAgent. If you’re VAT-registered or affected by Making Tax Digital, a bank feed that syncs cleanly with your accounting software saves real time every quarter.

Deposit protection. Money held with a fully licensed UK bank is protected by the Financial Services Compensation Scheme (FSCS) up to £120,000 per eligible depositor. E-money institutions (some fintech providers fall into this category) safeguard your funds differently — worth checking which category your provider falls into if you’ll be holding significant balances.

What Does It Cost?

Pricing varies a lot depending on the type of provider:

  • Digital challenger banks (Starling, Tide, Monzo, Mettle) often have a free tier with no monthly fee, though some charge a small fee per transaction beyond a certain number of free transfers (commonly around 20p each once you’re over your allowance).
  • Traditional high street banks typically charge a monthly fee, often somewhere between £5 and £25, though many offer an introductory free period (sometimes up to 12 or 18 months) for newly formed businesses.
  • Paid tiers on digital banks (for extra features like multiple user access, higher cash deposit limits, or better accounting integration) generally run from around £7 to £20 a month.

A few other costs worth factoring in:

  • Cash and cheque deposit fees, if your business handles physical money
  • International payment and currency conversion charges, which vary significantly between providers
  • Overdraft or lending costs, if you’ll need access to credit

The trick is not to just look at the headline monthly fee. A “free” account that charges per transaction can end up costing more over a year than a paid account that bundles everything in, if you’re processing a high volume of payments.

How to Choose the Right One

There’s no single “best” business current account — it depends on how you work. Some questions worth asking yourself:

  • How many transactions do I make a month, and what does that cost me under each provider’s pricing?
  • Do I need branch access for cash handling, or am I happy banking entirely through an app?
  • Does it integrate properly with the accounting software I use, or plan to use?
  • Do I need multi-currency accounts or competitive international transfer rates?
  • Will I need an overdraft or business lending down the line, and does this provider offer that?
  • How quickly do I need the account up and running?

The Bottom Line

A business current account isn’t just a box to tick — it’s the financial hub your business runs on. Take the time to get the right one for how you actually operate, rather than just picking whichever bank you already use personally. It’ll save you admin, save you money, and set you up properly for the conversations you’ll eventually have with lenders, investors, or your accountant.

If you’re not sure where to start, compare two or three providers side by side against your actual transaction habits before committing — the right fit is rarely the one with the flashiest sign-up offer.
