Buying a business
What is the UK equivalent of an SBA loan?
The UK equivalent of an SBA loan is not one scheme but two: the Growth Guarantee Scheme and Start Up Loans. How they map, and where the map breaks down.
There is no single UK equivalent of an American SBA loan. The closest match is a pair of government-backed schemes. The Growth Guarantee Scheme covers established businesses, and Start Up Loans cover the smallest end. Different mechanics, same intent. Here is how they map, and where the map breaks down.
Section 01
The short answer
- The institution. The rough counterpart to the SBA is the British Business Bank. Like the SBA, it does not lend to you directly. It backs and accredits the lenders who do.
- The guarantee. The Growth Guarantee Scheme is the nearest thing to SBA-style guaranteed lending. It gives the lender a 70% government-backed guarantee on facilities of up to £2m, for any legitimate business purpose. Delivery is through accredited lenders applying their own credit policy (British Business Bank, checked 31 August 2026).
- The small end. The nearest thing to an SBA microloan is a Start Up Loan. It is a government-backed personal loan for business purposes: £500 to £25,000 per founder at 7.5% fixed, over one to five years. It can be used to buy an existing business (GOV.UK, checked 31 August 2026).
Section 02
Where the map breaks down
Three differences catch buyers who learned the American system.
- The guarantee protects the lender, not you. True in both countries, and misread in both. You remain liable for the full loan.
- There is no UK culture of 90% acquisition lending. SBA 7(a) deals routinely fund most of a purchase price. UK lenders usually want the buyer contributing 10% to 30%. Vendor finance does much of the remaining work.
- Pricing is lender-set. The UK schemes do not impose an SBA-style standardised rate structure. Each accredited lender prices to its own book.
Section 03
What buyers used to the US system usually miss
Vendor finance is the UK's quiet workhorse. Where an American buyer reaches for a bigger guaranteed loan, a UK buyer asks the seller to defer part of the price. Lenders here expect to see it, and it brings your cash requirement down.
Personal guarantees are standard on most UK facilities. And because each accredited lender applies its own policy, the same deal can be declined at one desk and approved at another. Routing the case well is most of the game.
