The short version: Online business banks cut fees by 60-80% compared to high street alternatives, but they're not all equal; choose based on whether you need in-person support, international payments, or just a cheap UK account.
I switched my business bank three times in five years. Here's what I learned.
The first time I moved my business account online, in 2019, I felt like I was breaking a rule. Small business owners were meant to have relationships with their bank, weren't they? Someone who knew your name, your overdraft history, your dreams. That person did not exist. They existed only in my imagination and in the bank's marketing.
What I discovered instead was this: online business banking is faster, cheaper, and honestly better than the high street version. Not in some abstract future way. In real, immediate ways. No more queuing. No more explaining my business to someone reading from a script. No more surprise fees for sending money abroad.
But here's the thing nobody tells you: they're not all the same, and choosing the wrong one costs you real money and real hours.
Why online business banking beats the traditional model
A standard business current account at a High Street bank like Barclays, HSBC, or Natwest charges you between 10 and 25 pounds per month, plus transaction fees. Add in the cost of paying someone to sit in a branch and wait, and you're paying about 300 pounds a year just to have the account.
Most online business banks charge nothing. Absolutely nothing. Between zero and 12 pounds monthly, depending on the provider.
That's the baseline. But the real difference shows up in three places:
- You can open an account in 15 minutes from your desk, not three visits to a branch with forms in triplicate
- International payments cost 3 to 8 pounds instead of 25 to 50 pounds per transfer
- You get a real notifications system, not a statement that arrives six weeks late
I was wasting around 600 pounds a year on bank fees alone before I switched. For a small business, that's not nothing. That's the price of professional software, or two days of contractor work, or a decent workshop I should have done.
The banks I've tested (not the ones you read about in listicles)
Revolut Business launched in the UK in 2021 and changed what I expected from a business bank. It's free. The app is faster than your mail. International transfers to 150+ countries cost a flat 2 to 8 pounds. You can freeze your card in the app if you're paranoid. I've had it for four years.
The catch: Revolut is not a real bank. It's a fintech platform. Your money sits with an actual bank (currently Barclays), but Revolut manages the interface. For most of us, this is fine. For some people, this is a dealbreaker, and I understand that.
Starling Business is a real bank (licensed, all the protections, the full thing). Monthly fee is 5 pounds. You get a UK sort code and account number immediately. Transfers between Starling accounts are instant. I've tested it and like the interface better than my personal Starling, which is unusual.
Wise Business (formerly TransferWise) is not primarily a bank account. It's a payment platform. But you can use it as a business account for international payments and holding multiple currencies. The fee structure is transparent to the pound. If you're sending money to the US or Europe regularly, this saves money and days.
Tide describes itself as a business banking app. It's also not technically a bank, but it works like one. Zero monthly fee, fast setup, clean invoicing features built in. I haven't used it long-term, but three other business owners I know have, and they've stayed. That means something.
For comparison, I'll name the ones I don't recommend: NatWest and Barclays charge you for the privilege of being their customer, which feels medieval in 2026. HSBC is fine if you need commercial lending, but that's the only reason to use them.
Which one works for your situation
Here's the decision tree I use:
Do you need in-person banking? Go to Starling. It's a real bank with actual customer support on the phone, not a helpline that asks you to verify your identity four times.
Do you send money abroad more than once a month? Go to Wise Business or Revolut. Wise is better if you're converting currencies regularly. Revolut is better if you want a debit card that works everywhere without asking permission first.
Do you need a completely traditional bank experience with zero fintech involved? You don't. Stop doing that. But if you're certain, use Starling and accept that you'll pay for the privilege.
Do you need invoicing features built in, or do you use Xero already? Tide or Starling. The invoicing doesn't matter as much as you think it will, but it's nice to have.
Are you opening a second business account just to try online banking? Use Revolut. Zero risk, zero cost, and you'll know in a week if it's right for you.

What I didn't expect to matter (but does)
The app notifications are honestly worth more than free banking. With my old bank, I found out about payments three days after they cleared. With Revolut, I know within seconds. When you're running a business and cash is tight, that information gap matters.
The customer support quality varies wildly. Starling's support is actual humans who understand business. Revolut's support is chatbots trained well enough that you don't immediately want to scream. Tide's support I haven't tested much because I haven't needed it.
The ability to set spending limits and freeze the card instantly from the app sounds silly until you need it. That's a feature that costs nothing to provide and saves your business thousands if something goes wrong.
I switched to Revolut primarily because I was sending money to Israel monthly, and the foreign exchange rates were costing me 50 to 80 pounds per month. Not a lot, but annoying. Revolut's rates are transparent and competitive. It took me three months to realise the real benefit was the immediate notifications, which made cash flow forecasting possible.
The practical steps to switch
This is easy and takes 15 minutes, which is why you should do it now instead of waiting for "the right time".
- Pick one from the list above based on the decision tree I gave you
- Download the app, sign up, and upload a photo of your business registration or your passport
- They verify you within 24 hours
- You get a sort code and account number and can receive payments immediately
- Set up a standing order to move your supplier payments or personal salary to the new account, one at a time
- Keep the old account open for 30 days. Nothing will break
- After 30 days, close it
That's it. You're done. You've saved yourself 600 pounds a year and gained better tools.
The only exception is if you have a business loan or overdraft facility with your old bank. In that case, you need to make sure the new bank can either match it or you arrange a replacement first. Most online banks don't do lending (they're not yet licensed to do so), so this is worth checking before you move.
One more thing that matters
I've been running a business for 15 years. The switch to online banking happened in year 7, and I should have done it in year 2. It's not a risk. The money is protected by the same regulatory framework as any other UK bank account. Your money in Revolut, Starling, or Tide is covered by the Financial Services Compensation Scheme if something goes wrong, up to 85,000 pounds.
The only real risk is if you choose badly and waste time switching again. So: test it first. Revolut or Tide for two weeks. If you hate it, close the account. If you don't, keep it and move your main account over.
That's the entire conversation.
Frequently asked questions
Can I use an online business bank account with my accountant?
Yes, completely. Any online business bank will give you statements that your accountant can import into Xero, FreshBooks, or whatever else they use. Some accountants are nervous about fintech accounts (like Revolut) for audit purposes, but most now accept them without question. Ask your accountant first if you're uncertain.
What happens to my money if the online bank fails?
Your money is protected up to 85,000 pounds under UK Financial Services Compensation Scheme rules. This applies to Revolut, Starling, Wise, and Tide equally. They're all regulated. The money doesn't disappear.
Can I get a business loan or overdraft from an online bank?
Not yet from most of them. Starling is working on lending products but doesn't have a full suite yet. If you need a business loan or overdraft, you'll need to either get it from your current bank before you switch, or use a specialist lender and keep a traditional bank account for that facility.
Is it expensive to switch back if I change my mind?
No. Switching accounts is free and takes about 15 minutes. There are no exit fees or penalties. Most people keep their new account and close the old one, but you can also keep both if you're nervous.
