Quick Overview: How to Choose a Business Bank Account in 2026
Starting a business in the UK means you need the right bank account from day one. Most entrepreneurs make the mistake of using their personal accounts, which can create accounting nightmares and cause legal problems for limited companies.
Here’s what you need to do in 3 simple steps:
Step 1: Determine Your Business Structure
If you’re a limited company, you are legally required to have a separate business account. Your company is a separate legal entity from you. As a sole trader, you can technically use a personal account, but it’s strongly recommended to set up a business account for cleaner bookkeeping.
Step 2: Identify Your Top Needs
Ask yourself these questions:
-
Do I need completely free banking, or can I pay £5-15/month for extra features?
-
Will I deal with multiple currencies internationally?
-
Do I need cash deposits (many digital banks have limits)?
-
What accounting software do I use (Xero, QuickBooks, FreeAgent)?
-
How important is mobile app quality to me?
Step 3: Compare and Apply Online
Most UK business accounts now offer instant online applications with decisions in minutes. You’ll need:
-
Photo ID (passport or driving license)
-
Proof of address (utility bill under 3 months old)
-
Companies House registration number (for limited companies)
-
Business details (trading address, expected turnover)
The tech solution is straightforward: digital banks like Starling, Tide, and Revolut process applications entirely through their apps, while traditional banks like NatWest still offer branch visits if you prefer face-to-face service.
Top 5 Best Business Bank Accounts for UK Startups
Based on 2026 reviews, Trustpilot scores, and real user feedback, here are the top choices:
Starling Bank takes the top spot because it’s a fully licensed UK bank (not just an e-money service), offers completely free banking with no hidden charges, and has 24/7 customer support. Over 500,000 UK businesses have switched to Starling.
Free Business Bank Accounts for New Companies
If you’re launching with limited cash, these free options work well:
Starling Bank — Completely free forever, no monthly fees, no transaction fees. Includes business debit card, mobile banking, and integration with accounting software. The only limit is a £5,000 cash deposit per day for sole traders.
Tide Free Plan — £0/month for a basic account with 60 free transactions monthly. After that, £0.20 per transaction. Includes invoicing tools and expense cards.
Wise Business — No monthly fee, you only pay for what you use. Excellent for businesses receiving international payments. You get local bank details in 8 currencies.
Mettle (NatWest group) — Free for sole traders and partnerships with no monthly fee. Includes a cash deposit of up to £1,000/month free.
Pro Tip: Most “free” business accounts make money from transaction fees or upgraded plans. Starling is genuinely free with no hidden charges — check their terms directly before signing up.
Business Bank Account UK Sole Trader Comparison
Sole traders have different needs from limited companies. Here’s how top accounts compare:
Mettle is ideal for sole traders who regularly deposit cash, as it’s the only free account that offers a monthly cash deposit allowance. Starling works best if you rarely deal with cash and want the best app experience.
Note: Cashplus recently rebranded to Zempler Bank, but their core offering remains focused on guaranteed approvals and accessible accounts.

Not checking FSCS status — E-money accounts safeguard funds differently from bank accounts.
