Acquisition finance for small businesses: how to fund a business purchase in the UK

This guide explains how small businesses can fund a business acquisition, management buyout or buy in, covering the finance options, typical costs, deal structuring and the application process.

Acquisition finance is funding used to buy another business, whether that means purchasing a company outright, backing a management buyout, or financing a buy in. Small businesses typically put together a package of several finance types rather than relying on one loan, blending a term loan or asset based facility with a personal deposit, seller finance, or outside investment to cover the purchase price. This guide covers what acquisition finance actually pays for, the different ways to structure it, how much you can borrow, what it costs, and how lenders and investors decide whether to back your deal.

What is acquisition finance?

Acquisition finance is the umbrella term for any funding used to buy an existing business, rather than start one from scratch or invest in your own company's growth. It can mean a single business loan, or a combination of debt, equity and seller finance stacked together to complete a purchase. Unlike a standard business loan, acquisition finance is assessed against two sets of numbers at once, your own financial position and the trading history of the business you want to buy. That's what makes it more document heavy and slower to arrange than everyday borrowing, since the lender or investor needs enough evidence that the combined business can service the debt once the deal completes.

What can acquisition finance be used for?

Acquisition finance covers several different types of deal, and the right funding mix often depends on which one you're doing.

  • Buying an existing independent business outright, sometimes called a trade acquisition

  • A management buyout, where the current management team buys the company from its owners

  • A management buy in, where an external manager or investor buys a controlling stake and takes over running the business

  • Buying a franchise unit from an existing franchisee or the franchisor

  • Acquiring a competitor or supplier to grow market share or secure your supply chain

  • Merging with another business, where funding covers a cash element of the deal alongside a share exchange

What types of finance make up an acquisition finance package?

Most acquisitions are funded through a mix of debt, equity and deferred payment to the seller, rather than a single product. The right combination depends on the size of the deal, how asset rich the target business is, and how much you can put in yourself.

Finance type

How it works

Best suited to

Term loan

A lump sum from a bank or specialist lender, secured against the business and repaid in fixed instalments

The core of most acquisition finance packages, where the target has stable, provable cash flow

Asset based lending

Borrowing against a combination of the target's invoices, stock, equipment and property

Asset rich acquisitions where a standard loan wouldn't cover the full purchase price

Mezzanine finance

Subordinated debt that ranks behind senior lenders, often with a higher interest rate or a small equity stake attached

Bridging a gap between senior debt and the deposit you can raise, without giving up as much equity as a full investor round would

Equity investment

Capital from the management team, a private investor, or a private equity firm, in exchange for a share of the business

Larger deals, or buyers who want to reduce how much debt the new business carries after completion

Seller or vendor finance

The seller agrees to accept part of the price in instalments or as an earn out tied to future performance

Reducing how much you need to borrow upfront, and bridging a valuation gap between buyer and seller

How is a management buyout or buy-in financed?

A management buyout or buy in is usually financed with a blend of the management team's own capital, a business loan or asset based facility, and often mezzanine finance or seller deferred payments to close any remaining gap. The management team rarely funds the whole deal from savings alone, since most buyouts and buy-ins are priced well beyond what an individual or small group could put in without borrowing or bringing in an investor.

Lenders and investors backing a buyout look closely at the management team's experience running the business day to day, not just the numbers on the balance sheet, since continuity of leadership is part of what makes the deal lower risk than selling to an outside buyer. If you're planning a buyout or buy in specifically, we can help you compare management buyout finance, including how to structure equity, debt and seller finance together.

How much of an acquisition can you fund with debt?

Lenders will typically fund between 70% up to a maximum of 90% of the purchase price for a well established, profitable target business, with the rest expected to come from your own deposit, seller finance, or an equity investor. How much debt a deal can carry depends mainly on the strength of the target's cash flow, not just the asking price.

Lenders size the loan against a multiple of the target company's maintainable profit, commonly measured as EBITDA, rather than lending against the purchase price alone. That means an overpriced business can be harder to fund in full even with a strong deposit, since the debt still needs to be serviced from what the business actually earns once you own it. If you want to reduce how much you need to borrow, combining a smaller loan with seller finance or an equity partner can bring the cash you need at completion closer to the full purchase price without a single facility covering all of it.

What do lenders and investors look for before funding an acquisition?

Lenders and investors assessing acquisition finance look at both your own track record and the target business's numbers before deciding whether to back the deal. Expect to provide the following:

  • A business plan setting out why you're buying the business and how you plan to run it

  • Two to three years of the target's historic accounts and management information

  • Evidence of relevant management or industry experience, especially if the sector is new to you

  • Details of the target's key contracts, customers and any assets included in the sale

  • Your own personal financial position, including any assets you can offer as security

Most acquisition loans from high street and challenger banks will also ask for a personal guarantee, meaning you agree to repay the debt personally if the business can't.

Due diligence is the process of checking the target business's finances, contracts and legal position before you commit to the deal, and it runs alongside, not after, your funding application. Your lender or investor will usually want sight of the same information your own advisers are reviewing, since their decision to fund the deal depends on it too.

A typical acquisition also involves a few legal steps worth planning finance timelines around.

  • Heads of terms, a non binding outline of price and key conditions agreed with the seller before due diligence begins

  • Warranties and indemnities in the sale agreement, where the seller confirms certain facts about the business and agrees to compensate you if they turn out to be false

  • Completion accounts or a locked box mechanism, which fix exactly what working capital and cash the business has on the day you take over

  • An earn out clause, if part of the price depends on the business hitting agreed targets after you buy it

Because funding needs to be completed alongside these legal steps, acquisition finance timelines usually run four to eight weeks from application to funds being released, longer than a standard business loan.

How do you apply for acquisition finance?

Applying for acquisition finance follows a similar shape whether you're buying an independent business or backing a management buyout, though the amount of paperwork depends on the size and complexity of the deal.

  1. Agree heads of terms with the seller, including price and any key conditions, before approaching lenders or investors

  2. Prepare a business plan and financial projections showing how the combined business will perform and service any new debt

  3. Gather the target business's historic accounts, management information and details of its key contracts

  4. Apply through Capitalise, where we compare acquisition finance across a panel of 130+ UK lenders in one application rather than approaching each one individually

  5. Provide your own financial information and agree security or a personal guarantee where a lender requires it

  6. Complete legal due diligence alongside the lender's own checks, then draw down funds at completion

What are the most common mistakes to avoid when financing an acquisition?

A few pitfalls are worth planning around before you agree on a price:

  • Overpaying relative to the target's maintainable profit, which makes the debt harder to service once you own the business

  • Underestimating professional fees, since legal, accountancy and valuation costs on an acquisition are typically higher than on a standard loan

  • Leaving funding until after heads of terms are agreed, which can put you under time pressure and reduce your options with lenders

  • Assuming one lender's decision reflects the whole market, when a specialist lender or a blended funding package might fund a deal a generalist bank turns down
