Why your choice of business bank account can decide whether you get a loan
You've just incorporated. Companies House has sent the certificate, HMRC has sent a letter about Corporation Tax, and now you need somewhere to put the money. The obvious move is to download Tide or Starling, get an account in fifteen minutes, and get on with your day.
That's fine for month one. It can be a problem in month fourteen, when you go to borrow.
This article is about the gap between "any business account will do" and "the account a lender actually wants to see". The short version: nothing in the rules says you must bank with Barclays, HSBC, Lloyds, NatWest, Santander or Nationwide (the Big Six) to get a loan. But your banking setup shapes how easy it is to get one, and how much you can get. Here's how.
First, the honest bit: what lenders actually require
Funding Circle's eligibility criteria don't name a bank. Its own guidance on business credit cards says there is no requirement to hold or switch to any particular business account. What it does need is a UK limited company or LLP with at least a year of trading, a UK business bank account in the company's name, and clean financials.
Two things in that list matter more than most founders realise:
Sole traders are now out. Funding Circle stopped lending to sole traders and general partnerships in February 2026. If you set up as a sole trader "to keep things simple", Funding Circle is closed to you until you incorporate. This is one of the quieter arguments for forming a limited company from day one.
The bank account is the application. Funding Circle and iwoca both assess you primarily through open banking. You connect your business account, and they read the transaction history directly instead of asking for printed statements, accounts or a business plan. That means the quality of your bank data is the quality of your application.
So the question isn't "does Funding Circle demand a Big Six account?" It's "which account produces the cleanest, most credible picture of my business when a lender looks at it?"
Where fintech accounts fall short
1. Some of them aren't banks
Tide is an e-money institution, not a bank. Your money is safeguarded, but it isn't covered by the FSCS, and Tide itself can't lend to you. Lenders know the difference. An account at a licensed bank (Starling, Monzo and Revolut all hold full UK banking licences now, as do the Big Six) reads as a more established relationship than a safeguarded e-money wallet. This won't get you declined on its own, but underwriters assessing a young company look at every signal, and "banks with a real bank" is one of them.
2. They don't do serious lending
Business Expert's 2026 comparison puts it plainly: neither Tide nor Monzo replaces a high-street business bank. No relationship managers, limited cash handling, and if you need sizeable lending you're told to pair the account with Lloyds, Barclays or NatWest. Starling has removed business loans; Zempler has removed its credit card. Starling now routes lending customers to iwoca. When the digital banks themselves are pointing you elsewhere for credit, that tells you something.
3. You have no relationship to fall back on
Alternative lenders like Funding Circle are a good option, but they aren't the cheapest option. A high-street bank that has watched your account for two years, seen consistent turnover and no bounced payments, is in a position to offer an overdraft, a term loan or a government-backed facility at rates the fintech lenders can't match. Barclays and HSBC are active British Business Bank lenders. If you've never banked with them, that door is much harder to open in a hurry.
4. Direct debits and disbursement
Most lenders collect repayments by direct debit and pay out by Faster Payments. Licensed banks handle both without friction. Most e-money providers do too, these days, but a few still route direct debits through third parties. It's a small thing until a repayment fails and you're explaining it to a credit team.
Where fintech accounts win
This isn't a "high street good, app bad" piece. The digital accounts are better at the day-to-day: instant setup, free UK transfers, tax pots, built-in invoicing, and accounting integrations that make Making Tax Digital far less painful. High-street business accounts often take one to three weeks to open, charge £6 to £10 a month after the free period, and have apps that still feel like 2015.
If you only ever plan to borrow from Funding Circle or iwoca, a Starling or Monzo account will do the job. Both are FSCS-protected, both connect cleanly via open banking, and both produce the transaction data those lenders want.
The setup we recommend for new directors
Run two accounts, and decide which is the "main" one before you start trading.
Main account: a Big Six bank. Open it early, because it takes weeks, and route your customer receipts and supplier payments through it. This is the account you'll connect to open banking when you apply for finance, and it's the one that builds a track record with a lender who can also become your cheapest source of credit later.
Operating account: a fintech. Use Starling, Monzo or Tide for the things they're good at: tax pots, cards for staff, invoicing, and the accounting feed. Transfer a working float across each month.
The mistake is doing this the other way round, with turnover flowing through a fintech account and the high-street account sitting empty. An empty NatWest account with £14 in it does nothing for you. A NatWest account showing twelve months of steady receipts is a loan application waiting to happen.
What to do this week if you've just incorporated
- Apply for a Big Six business account now, before you need it. Expect it to take a fortnight or more. Have your certificate of incorporation, proof of address and a short description of what the business does.
- Open a fintech account in the meantime so you can start invoicing and paying suppliers.
- Once the high-street account opens, move the main money flow across. Update your invoice templates and standing orders.
- Keep the account clean. No unexplained personal spending, no bounced payments, no repeated overdraft dips. Lenders read twelve months of this.
- Mark your calendar for month twelve. That's when Funding Circle becomes an option for a limited company. If you've run a clean account for a year, the application is a ten-minute job.
Setting up your banking is part of launching properly
SohoSumo sets up new UK directors with the accounts, registrations and systems that a lender, an accountant or a customer would expect to see. Banking is one piece of that. If you'd rather not work out the sequencing yourself, take a look at what's included.
