Buying a business
How much deposit do you need to buy a business?
How much deposit do you need to buy a business in the UK? Most buyers put in 10% to 30% of the price. What counts, and how vendor finance shrinks it.
For most UK SME acquisitions the buyer puts in 10% to 30% of the purchase price as a deposit. The percentage applies to the price of the business, not to the size of the loan. Strong cashflow and meaningful vendor finance can bring it below 15%. Here is how lenders actually count it.
The deposit question is the one buyers get wrong most often. The mistake is rarely the number itself. It is the thing the number is a percentage of. Get that right and the rest of the funding plan falls into place.
Section 02
How much deposit do you need to buy a business?
Across the deals we arrange, most buyers contribute between 10% and 30% of the price. Where you land in that range depends on three things.
- The target's cashflow. Steady, well-evidenced earnings support more debt, which means less cash from you. Volatile or seasonal earnings push your share up.
- Your track record. Sector experience and previous ownership lower the perceived risk. First-time buyers get funded every week. Lenders just tend to want a little more skin in the game.
- The asset base. A business with plant, stock, or invoices to lend against gives the lender security. Asset-light service businesses lean harder on your deposit.
Treat 10% as the realistic floor for a straightforward deal with vendor support. Treat 30% as the planning figure for a first-time purchase of an asset-light business. Budget between the two and let the lender conversation move you, not hope.
Section 03
What counts as your deposit, and what does not
Lenders want to see that the deposit is genuinely yours. The test is simple. Does this money have to be paid back to someone else ahead of the deal working out?
These usually count without argument.
- Cash you have saved, in your name, with a paper trail.
- Equity you release from property or investments, documented.
- Gifted family money, supported by a letter confirming it is a gift.
- Value you leave in the deal. On a partial buy-out, the stake you already hold works like equity.
Two things weaken the case. A deposit that is itself borrowed, with its own repayments, cuts across affordability. It usually has to be declared, and it rarely survives underwriting quietly. And money that appears without a story invites questions you do not want at credit stage. Provenance matters as much as the amount.
Section 04
Vendor finance can shrink the cash you need
The most under-used lever in SME deals is the seller. In a vendor-financed deal the seller leaves part of the price in the business as a loan. It is repaid from trading over an agreed period.
Senior lenders usually count a vendor loan towards your side of the deal, close to equity. The condition is that it ranks behind them and cannot be repaid first. That is why a meaningful vendor loan can bring your cash contribution below 15% of the price.
Everyone gets something. The seller gets a full-price deal and a smooth handover. You get a smaller cheque on day one. The lender gets a seller with a reason to care that the business keeps performing.
Sellers offer it more often than buyers expect. Retirement sales are the classic case, where the alternative may be no deal at all. Ask early, before the price conversation hardens.
Section 05
Where the rest of the money comes from
Once the deposit and any vendor loan are set, the remaining balance is funded from a stack of one or more facilities.
- Cashflow-led term loans sized against the target's maintainable earnings. The core of most deals.
- Asset-backed facilities against plant, stock, or the invoice book. These stretch what cashflow alone would support.
- Growth Guarantee Scheme facilities. The government-backed scheme gives the lender a 70% guarantee on facilities of up to £2m. It covers any legitimate business purpose, subject to each lender's own credit policy (British Business Bank, checked 30 August 2026). The current rules are covered in our Growth Guarantee Scheme guide.
- Start Up Loans for the smallest purchases. The government-backed scheme lends £500 to £25,000 per founder at 7.5% fixed, over one to five years. Buying an existing business is explicitly allowed, provided you have not owned it yourself for more than 60 months (GOV.UK, checked 30 August 2026).
How the layers fit together, and what a full deal timeline looks like, is covered step by step in how acquisition finance actually works.
bizbritain is an FCA-authorised finance broker arranging acquisition finance from £25,000 to £10m. We structure the deposit, the vendor loan, and the debt layers as one stack, not three separate conversations. If you are pricing a deal, send us the numbers.
