Financing a business acquisition in the UK
Most UK small business acquisitions are funded from three or four sources at once rather than one: buyer capital, a commercial loan secured on the assets or property, and vendor finance from the seller. What you can borrow depends less on the price than on what a lender can take security over, which is why leasehold service businesses are harder to fund than freehold ones.

Very few small business acquisitions are funded from one source. The usual shape is three or four layers stacked together, and understanding why they stack that way makes the whole thing considerably less mysterious.
The thing lenders are actually assessing
Not the price. What they can recover if it goes wrong.
This is the single most useful idea in acquisition finance and it explains almost every decision a lender makes. A business with freehold premises has an asset that retains value whether or not the business trades. A leasehold consultancy whose value is goodwill and client relationships has an asset that is worth close to nothing the moment it stops operating.
So two businesses at the same price, with the same profit, attract very different lending. Which in turn means: decide your funding structure before you choose the business, because the tenure and the asset base change what you can buy.
The second thing they assess is you. Your sector experience, your track record, and whether you can plausibly run this specific business. A credit committee that has never met you is forming a view from a business plan and a CV.
Layer one: your own capital
Every route requires some. Cash, savings, a pension where the rules permit certain structures, released equity, or money from family.
Lenders want to see meaningful buyer contribution for a straightforward reason: a buyer with nothing at stake behaves differently from one who has committed their own money.
Layer two: commercial lending
Commercial term loans. The main route. A bank or a specialist commercial lender advances against the business, usually secured over its assets, frequently with a personal guarantee, and typically repaid over a period of years. Availability and terms vary widely by lender, sector and security, which is the argument for a broker rather than approaching one bank.
Asset finance. Funds specific equipment, vehicles or plant, secured on the item itself. Useful in an acquisition to release cash: refinancing the existing assets on completion can fund part of the price.
Commercial mortgage. Where the business owns its premises, the property is financed separately. This is normally the cheapest money in the structure and the largest single component where it applies.
Invoice finance. Advances against the debtor book. Not usually acquisition funding on its own, but it releases working capital on completion, which matters because working capital is where first-time buyers most often run short.
The Growth Guarantee Scheme. A British Business Bank scheme that provides accredited lenders with a government-backed guarantee on qualifying facilities, intended to support lending to smaller UK businesses that might otherwise struggle to obtain it. It supports term loans, overdrafts, asset finance, invoice finance and asset-based lending, and the guarantee is to the lender rather than to the borrower: the borrower remains fully liable for the debt. Eligibility, facility sizes and terms are set by the scheme and change, so check the current position with the British Business Bank and with an accredited lender rather than relying on any summary, including this one.
Layer three: vendor finance
The seller leaves part of the price outstanding and you pay it over time, usually with interest, often secured, and commonly over two to four years.
It is extremely common in small business sales and it is worth understanding why both sides like it.
For you: it reduces the cash needed on completion and is often available where commercial lending is not, because the seller is lending against a business they know rather than one they have read about.
For the seller: it frequently gets a deal done at a price that would otherwise fail, and it can have tax advantages depending on structure and timing, which is a question for their accountant rather than for you.
The signal matters as much as the money. A seller who will not leave anything in the business has told you something about their confidence in it. A seller who will is putting their assessment where their mouth is. It is worth asking the question even if you do not need the facility.
Get the security, the interest rate, the repayment schedule and the default consequences into the heads of terms. Vendor loans agreed loosely and documented late are a reliable source of argument.
Layer four: earn outs and deferred consideration
Strictly a pricing mechanism rather than finance, but it has the same effect on day one cash.
An earn out pays part of the price only if the business achieves stated results after completion. Useful where you are uncertain about revenue that depends on the departing owner: tie the payment to that revenue surviving, and the seller who believes their own figures will usually accept.
Deferred consideration is simply payment later on a fixed date, without the performance condition.
Both reduce what you need on completion. Both also mean part of your negotiation happens after you own the business, so define the measurement precisely before signing.
What a funded deal actually looks like
An illustrative structure for a £650,000 acquisition of a trade services business with no freehold:
| Source | Amount | Notes | | --- | --- | --- | | Buyer capital | £160,000 | Cash and released equity | | Commercial term loan | £280,000 | Secured on assets, personal guarantee | | Asset refinance | £70,000 | Vehicles and plant | | Vendor loan | £140,000 | Over 3 years, interest bearing, secured | | Total | £650,000 | | | Working capital reserve | £70,000 | Held separately, not part of the price |
That final row is the one buyers forget. The purchase price is not the amount you need. You need the price, the professional fees, the working capital to run the business through its payment cycle, any completion adjustment, and a reserve for the thing you did not find in due diligence.
What to do, in order
- Talk to a commercial finance broker before you look at businesses. An indicative view on what you can raise, against what kind of asset, narrows your search more than any other single step.
- Work out your working capital requirement separately. Model the cash cycle of the business you are buying, not a generic figure.
- Get an agreement in principle before granting or accepting exclusivity. A seller granting you exclusivity is taking their business off the market. A buyer who then cannot fund has cost them months.
- Read what is being secured, and by whom. Personal guarantees and charges over your home are the terms to understand fully rather than skim.
- Model the repayments against the adjusted profit. After debt service, after the manager's salary if you are not doing the job yourself, and after tax. If it only works on the forecast rather than on the historic figures, you are financing a plan rather than a business.
The honest summary
Funding an acquisition is harder than most first-time buyers expect and more achievable than most people who never try assume. The two things that make the difference are starting the funding conversation before the search rather than after, and choosing a business whose asset base a lender can work with.
And the discipline underneath all of it: the deal has to work on the numbers the business already produces. Every acquisition that gets into difficulty was funded on a forecast.
Common questions
- How much of the purchase price can I borrow?
- It depends almost entirely on what a lender can secure against. A business with freehold property supports considerably more lending than a leasehold business whose main asset is goodwill, because goodwill is worth little if the business stops trading. Speak to a commercial finance broker early, because the answer determines the size of business you can realistically pursue.
- What is vendor finance?
- The seller leaves part of the price outstanding and you pay it over an agreed period, usually with interest and often with security. It is common in small business sales because it bridges the gap between what a buyer can raise and what a seller wants, and because a seller willing to do it is signalling confidence in the business.
- Do I need to keep working capital available after completion?
- Yes, and underestimating it is a common and serious error. You are taking on the business's payment cycle from day one, and completion often coincides with settling the working capital adjustment. Fund the purchase and the first several months of operation separately.
- Is this financial advice?
- No. This article describes how acquisition funding commonly works in the UK. It is not advice, it is not a recommendation of any product or lender, and your own position depends on facts we do not have. Speak to a commercial finance broker, your accountant and, for anything involving your own home as security, an independent adviser.
