Business Banking for Tradespeople: Accounts, Merchant Fees & Cash Handling

Quick Answer: You are legally required to have a separate business bank account if you operate as a limited company (the company is a separate legal entity). As a sole trader, it is not legally required but is strongly recommended — mixing personal and business finances is the leading cause of tax errors and disputes with HMRC. Business accounts typically charge monthly fees (£5–20/month) plus transaction fees, but free business accounts (Starling, Monzo Business, Tide) exist. Card payment terminal fees typically 1.5–2.5% per transaction; watch for monthly rental charges.

Summary

Many tradespeople run their finances through a personal account, especially when starting out. This works until HMRC asks for records, a dispute arises, or the business grows enough that separating personal from business transactions becomes a weekly chore. The business banking setup for a tradesperson is simple: one account for income and expenditure; a savings pot or separate account for tax and VAT; a way to take card payments on site; and a clear record of cash transactions.

This article covers account selection, card payment options, cash handling requirements for HMRC, and the specific considerations for tradespeople who work partly in cash-paying markets.

Key Facts

• Limited company — must have a business bank account; the limited company is a separate legal entity; mixing company and personal funds "pierces the corporate veil" and can create personal liability; it also makes accounts preparation impossible
• Sole trader — no legal requirement for a separate account, but HMRC will expect to see business records separable from personal; a dedicated account is by far the easiest way to achieve this
• Business current account fees — traditional high street banks: £5–25/month plus 30–60p per transaction; free alternatives: Starling Business, Monzo Business (up to £0/month for basic; transaction fees apply for cash); Tide, Revolut Business (free tier with limitations)
• Cash deposit limits — free business accounts typically charge for cash deposits (50p–£1 per £100); if you handle significant cash, a high street bank with free branch deposits may be better despite monthly fees
• Overdraft — business accounts often include an arranged overdraft; sole traders relying on invoice payment have irregular income and an overdraft buffer helps manage cash flow between invoice and payment
• Merchant services / card payment — cost of accepting cards; typically 1.4–2.5% per transaction for UK Visa/Mastercard; American Express 2–3% (often charged to customer separately); plus terminal rental (£20–50/month) or use app-based readers (SumUp, iZettle/Zettle, Square)
• SumUp / Zettle / Square — app-based card terminals; no monthly rental; per-transaction rates (1.5–2.5%); card reader purchase £29–69; good for tradespeople who don't need a permanent terminal
• Bank transfers (BACS/Faster Payments) — free to receive from customers; standard for invoiced commercial work; all major banks support Faster Payments (same-day)
• VAT separate account — highly recommended practice to hold VAT collected in a separate savings account until quarterly VAT return is due; prevents accidentally spending VAT money
• Cash and HMRC — all income must be declared regardless of payment method; cash income is taxable; HMRC has powers to investigate cash businesses and can use bank statements plus lifestyle checks; claiming ignorance is not a defence
• AML (Anti-Money Laundering) — banks are required to report suspicious large or unusual cash transactions; deposits over £10,000 cash may trigger reporting; legitimate trades businesses should be able to explain cash flows; structuring deposits to avoid reporting thresholds is a criminal offence

Detailed Guidance

Choosing a Business Account

High street bank (Barclays, HSBC, NatWest, Lloyds):

• Pros: branch access for cash; large overdraft facilities; relationship manager for larger accounts; CIS refund claims handled (some banks); better for commercial mortgages if you need business lending
• Cons: monthly fees; slower to set up (ID checks in branch)

Digital bank (Starling, Monzo, Tide):

• Pros: free or low cost; instant setup; excellent mobile app; integrations with accounting software (Xero, FreeAgent)
• Cons: no branches for cash; limited overdraft; not always accepted by some larger clients expecting a "proper" bank
• Recommendation: for a sole trader or small limited company with mainly card/transfer payments, Starling Business or Monzo Business is hard to beat

What to check before opening:

• Can I deposit cash? (essential if you take cash payments regularly)
• Does it integrate with my accounting software?
• Is there an overdraft facility?
• What are the limits on Faster Payments?
• Is there a business savings account for VAT and tax reserves?

Card Payments on Site

Taking card payments on site is now expected by most customers. For tradespeople:

App-based readers (SumUp, Zettle, Square): Most suitable for the majority of trade businesses. No contract; one-off hardware purchase (£19–45); transaction fee of 1.69–1.75%. Works with any smartphone. Print receipts via Bluetooth printer or send by email/SMS. Weekly settlement to your bank account.

Traditional terminals on contract: Better suited to businesses processing >£15,000/month in card transactions, where the lower per-transaction rate justifies the rental cost. At 1.4% vs 1.75%, you save 0.35% — on £15,000/month that's £52.50/month, slightly offsetting a £20/month rental. At lower volumes, app-based readers are cheaper overall.

Payment links: All major app-based providers also offer payment links (send by SMS or email; customer pays on their phone). Excellent for invoiced work where you don't want to carry a terminal to collect the final payment — send the link when the job is done and receive payment the same day.

Cash Handling for HMRC

Cash income is taxable and must be recorded. HMRC is increasingly sophisticated at identifying undeclared cash income through:

• Bank statement analysis (looking for lifestyle costs exceeding declared income)
• Industry benchmarking (comparing your declared income to similar trades)
• Third-party data (customer deductions under CIS, supplier purchases)

Best practice for cash income:

1. Issue a receipt for every cash payment (even informally — a text message or email confirming the amount serves as a record)
2. Record all cash income in your books on the day received — do not wait until banking
3. Bank cash regularly; maintain a simple cash book showing opening float, income, expenditure (materials bought in cash), and banking
4. Do not mix personal and business cash

CIS and cash: Under the Construction Industry Scheme, subcontractors paid in cash by the main contractor are still subject to CIS deductions. Paying cash does not remove the CIS obligation — the contractor must still deduct tax and declare the payment to HMRC. HMRC's CIS records will show payments to subcontractors even if the subcontractor doesn't declare them.

VAT — Separating Collected Tax

If you are VAT-registered, 20% of your sales income belongs to HMRC and must be paid over quarterly. A common mistake is treating the full invoice amount as income and spending it, then being unable to pay the VAT quarter.

Simple discipline: On receiving any payment, immediately transfer the VAT element (20% of the ex-VAT amount, or 1/6 of the VAT-inclusive total) to a separate savings pot or account. This money is never your working capital — it belongs to HMRC.

Example: Customer pays £6,000 for a bathroom fit including VAT. Of this, £5,000 is your income; £1,000 is VAT. Transfer £1,000 immediately to the VAT pot. Your working capital is £5,000.

Frequently Asked Questions

Can I use my personal account if I'm a sole trader?

You can, but it is strongly discouraged. HMRC will look at all transactions on a personal account during an enquiry, including personal spending, which then requires explanation. A dedicated business account makes bookkeeping and tax returns much simpler and is generally viewed more professionally by clients paying by bank transfer.

My customer wants to pay cash. Is there anything I need to do?

Issue a receipt, record the income in your books on the day received, and bank it regularly. The income is taxable. Under anti-money laundering rules, accepting a large cash payment (over a few thousand pounds) without a clear business relationship or explanation could be a money laundering risk — for very large cash payments, consider requesting a bank transfer instead and explain why.

What bank account for a brand new limited company?

Starling Business or Monzo Business are the quickest to set up (typically same day or next day, with a phone and Companies House number). For established businesses needing lending or a large overdraft facility, a high street bank relationship is worth building. Many companies start with a digital bank and add a high street account later when they need lending.
