Business Banking for a Limited Company: Everything You Need to Know
When you set up a limited company in the UK, one of the first practical steps is opening a business bank account. Unlike sole traders — where the line between personal and business finances can sometimes blur — a limited company is a separate legal entity, and that separation should be reflected in how you manage its money.
Your company's business bank account is where client payments land, where you pay suppliers and staff, and where HMRC will look when it examines your records. Getting this right from day one saves significant headaches when it comes to filing your company accounts and tax return.
Key takeaways
- A limited company is a separate legal entity — its money belongs to the company, not to you personally
- Most personal bank accounts explicitly prohibit business use in their terms and conditions
- Business bank accounts range from free challenger bank accounts to full-service accounts at high street banks with monthly fees
- You will need your Companies House registration number, certificate of incorporation, and proof of identity to open an account
- Keeping business and personal finances separate makes bookkeeping, expenses claims, and tax filing significantly easier
Why does a limited company need a business bank account?
A limited company is a distinct legal entity, separate from you as a director and shareholder. The money in the company belongs to the company — not to you personally. Mixing company and personal funds in a single account muddies this distinction and creates problems worth avoiding.
There are three core reasons to open a dedicated business account from the outset:
1. Personal accounts prohibit business use. Most high street banks' terms and conditions explicitly bar you from running a business through a personal current account. If your bank discovers you are doing this, it can close the account with little notice, leaving you unable to send or receive payments.
2. HMRC and your accountant expect clean records. When you file your company tax return (the CT600), your accountant or filing software reconciles income and expenditure against your bank statements. If business transactions are intermingled with personal ones, every statement requires manual sifting — time-consuming and prone to errors.
3. Limited liability depends on legal separation. One of the main advantages of incorporating is limited liability: you are generally not personally liable for the company's debts. Commingling funds blurs the boundary between you and the company, which can complicate matters if creditors or courts scrutinise the arrangement.

What to look for in a business bank account
Does the account suit your transaction volume?
A small consultancy invoicing a handful of clients each month has very different banking needs from a product business processing dozens of daily orders. Think about your anticipated monthly transaction count before choosing — most accounts either include a set number of free transactions or charge per transaction above a threshold.
Fees and charges
Business accounts typically charge in one or more of these ways:
| Fee type | What to check |
|---|---|
| Monthly account fee | Challenger banks often offer free tiers; high street banks typically charge £5–£12.50/month |
| Transaction fees | Some accounts charge per transfer, particularly for Faster Payments above a limit |
| Cash deposit fees | If you handle physical cash, these fees add up quickly |
| International payment fees | Relevant if you invoice overseas clients in foreign currencies |
| CHAPS / same-day payment fees | Typically £20–£30 per payment at some providers |
| Card fees | Some accounts charge for issuing additional debit or prepaid cards |
Integration with accounting software
If you use cloud accounting software — Xero, QuickBooks, FreeAgent, or Sage — check whether the bank offers a live data feed. A bank feed imports transactions automatically, eliminating hours of manual entry and making monthly reconciliation straightforward.
Most challenger banks (Starling, Tide, Monzo Business) have built-in integrations with major accounting platforms. High street banks have historically lagged here, though most now support Open Banking connections.
Customer support
When something goes wrong — a payment is delayed, a card is lost, a large client payment does not arrive — you want to reach a human quickly. Some challenger banks offer support primarily through in-app chat, which suits most situations but can frustrate directors when they need urgent resolution of a payment issue.
Savings and interest
If your company builds up a cash reserve — for example, setting aside funds for a future tax bill — some business accounts now pay meaningful interest on current balances or offer linked business savings accounts. This is worth factoring in if your company holds significant cash.
Overdrafts and credit facilities
If you anticipate needing short-term credit — to bridge a gap between paying suppliers and receiving client payments — check whether the bank offers an overdraft or business credit facility. Challenger banks are generally weaker here; high street banks have established lending products.
Types of business bank account
High street banks
Traditional banks such as HSBC, Lloyds, Barclays, NatWest, and Santander offer full-service business accounts with branch access, telephone banking, and business lending products. Key points:
- Branch access: Useful for cash deposits and counter services
- Lending products: Overdrafts, business loans, and credit cards readily available
- Monthly fees: Typically £6–£12.50/month after an introductory free period (often 12–18 months for new businesses)
- Application time: Can take one to three weeks for new limited companies
- Relationship managers: Available for larger accounts with turnover above a threshold
Challenger and digital banks
Digital-first banks have reshaped business banking significantly. Key players include Starling Business, Monzo Business, Tide, and Revolut Business. Their advantages:
- Fast account opening: Often within hours or a few days via a mobile app
- No or low monthly fees: Free basic accounts are common
- Excellent integrations: Most connect directly with Xero, QuickBooks, and FreeAgent
- Real-time notifications: Every transaction triggers an instant alert, making it easy to spot unexpected activity
- Spending categorisation: Automated tagging helps with bookkeeping and expense tracking
Which is right for your company?
For most small limited companies, a digital bank account is perfectly adequate for day-to-day operations — and often superior for ease of use and accounting integration. If your business regularly handles cash, needs an overdraft facility, or values a face-to-face relationship, a high street account may serve you better. Some directors hold accounts at both.
How to open a business bank account
What you will need
To open a business bank account as a limited company you will typically need:
- Your Companies House registration number (the eight-digit number on your certificate of incorporation)
- Your certificate of incorporation (freely downloadable from the Companies House register)
- Proof of identity for directors and Persons with Significant Control (PSCs) — usually a valid passport or driving licence
- Proof of address for the same individuals — a bank statement, utility bill, or official letter dated within the last three months
- Description of business activities — what your company does and your anticipated turnover
Steps to open your account
- Decide between a digital bank and a high street bank based on your transaction needs and any requirement for cash handling or credit
- Gather company documents (Companies House registration, certificate of incorporation)
- Prepare identity and address verification for all directors and PSCs
- Complete the application via the bank's app or website, or visit a branch
- Await approval — hours for digital banks, one to three weeks for high street banks
- Set up accounting software integration if available
- Update clients and suppliers with the new account details
Managing your company's cash flow effectively
A business bank account is the foundation. Strong cash flow management builds on top of it.
Ring-fence tax reserves. As client payments arrive, transfer the estimated corporation tax, VAT, and PAYE contributions to a separate savings account or clearly labelled pot. Spending money that belongs to HMRC is a common cause of cash flow crises for small companies.
Set up salary as a standing order. If you pay yourself a director's salary, set it up as a fixed standing order each month. This creates a predictable, easily explained pattern on your bank statements and simplifies your Self Assessment return.
Reconcile monthly, not annually. Reconciling your bank statement against your accounting records monthly takes around twenty minutes with a bank feed. Leaving it until year-end before accounts are due takes days — and allows small errors to compound into significant discrepancies.
Monitor aged debtors weekly. Your bank tells you what has arrived; your accounting software tells you what should have arrived. Review outstanding invoices regularly. Most late payments come from clients who simply forgot, not from those refusing to pay — a polite reminder email resolves the majority promptly.
Understand the difference between profit and cash. A profitable company can still run out of cash if clients pay slowly and suppliers demand payment quickly. Understanding your cash conversion cycle — the time between paying for work and being paid for delivering it — helps you plan ahead and avoid being caught short.
Business banking and your tax records
Your bank statements are a primary record for both HMRC and Companies House purposes. Keeping them clean and well-reconciled:
- Supports allowable business expenses claims — HMRC may ask for evidence that claimed expenses were genuinely business costs
- Makes it straightforward to identify dividend payments to shareholders (important for Self Assessment)
- Gives your accountant or tax filing software a reliable foundation for preparing your year-end accounts and CT600
- Reduces your risk profile in the event of an HMRC enquiry
Frequently Asked Questions
Is a business bank account legally required for a limited company?
No specific statute requires a limited company to hold a business bank account. However, most personal bank accounts prohibit business use in their terms and conditions, HMRC expects clear financial records that support your tax returns, and the company's legal status as a separate entity makes a dedicated account a practical necessity. Operating without one creates serious compliance and banking risk.
Can I use my personal bank account for my limited company?
In most cases, no. Your personal bank's terms and conditions almost certainly prohibit business use, and the bank can close the account if it discovers you are running a company through it. More fundamentally, a limited company's funds belong to the company — mixing them with personal funds undermines the legal separation that gives you limited liability.
How long does it take to open a business bank account?
Digital banks can open accounts within hours to a few days. High street banks typically take one to three weeks for newly incorporated companies. Applying promptly after registering your limited company means you are ready to send invoices and receive payments from the start.
What if the company has more than one director?
You will need to provide identity and address verification for all directors and any PSCs. Some banks require all directors to sign a banking mandate; others allow a single authorised signatory to manage the account with appropriate controls. Check the bank's policy before applying.
Can a limited company have more than one bank account?
Yes, and many do. A common setup is a main current account for day-to-day operations, a business savings account for tax reserves, and a merchant account for card payment processing. Multiple accounts at different banks are perfectly lawful.
Do I need a business bank account before I can invoice clients?
You can issue invoices before your account is open, but you cannot provide bank details for payment until the account is confirmed. It is best practice to open your account before your company starts trading so that everything is in place from the first invoice.
Summary
A business bank account is not just an administrative formality — it is the practical expression of your limited company's identity as a separate legal entity. Whether you choose the speed and simplicity of a digital challenger bank or the broader services of a high street provider, open the account promptly after incorporating, keep it reconciled regularly, and use it as the foundation for clean, compliant financial records. Every subsequent step — filing accounts, submitting your tax return, and demonstrating compliance to HMRC — becomes easier when you start as you mean to go on.
