How to Finance Buying a Business in the UK

Knowing how to finance buying a business is usually the thing that decides whether your search ends in a deal or in a drawer full of listings you couldn't afford. Almost nobody pays for an acquisition entirely from their own pocket. The price gets assembled from several sources stacked together: some of your own cash, a loan secured against the business or its assets, money the seller agrees to leave in, and sometimes an investor's equity. The art is in the mix, not in finding one magic source.

Start with the shape of the deal. A typical UK SME purchase is funded as a deposit you put in, plus borrowing that the business's own profits will repay over the next three to five years. Lenders want to see you have skin in the game, which is why a deposit matters, and they want to see the business throws off enough cash to service the debt after you've paid yourself. Those two tests run through almost every funding route below.

The money is out there. In the final quarter of 2025, gross lending to SMEs by the main high street banks hit £4.6bn, the eighth consecutive quarter of year-on-year growth, according to UK Finance. Lending to the smallest businesses grew fastest. So this isn't a frozen market where nobody can borrow. It's a cautious one where the buyers who prepare properly get funded and the ones who turn up with a vague plan and no numbers get a polite no.

This guide runs through every realistic route in turn: cash, bank acquisition finance, government-backed schemes, seller financing, asset and invoice finance, and equity. Then it covers how lenders actually judge a purchase, how much deposit you'll need, and how to blend the sources into a structure that completes. If you're still choosing what to buy, pair this with where to find a business for sale in the UK, because the price you can fund shapes the deals worth chasing. And when you're ready to look at live listings, you can browse businesses for sale on NewOwner and price the funding against a real number.

Cash funding means the portion of the purchase price you pay from your own money rather than borrowing it. It's the foundation almost every other route is built on, because it becomes the deposit lenders measure everything else against. Even a deal that looks heavily debt-funded usually has real cash underneath it.

Where does that cash come from? For most first-time buyers it's a blend of savings, a redundancy or pension lump sum, the proceeds of selling a previous business or property, and money from family. None of that is exotic. What matters is that the money is genuinely yours to commit and isn't already spoken for by your mortgage or your kids' school fees. A buyer who empties every account to scrape together a deposit and keeps nothing back for the first lean quarter is taking a real risk, because acquired businesses almost always need a working-capital cushion in the first few months while you find your feet.

There's a strong argument for putting in more cash than the minimum when you can. Every pound of your own money is a pound you don't borrow, which means lower monthly repayments, more headroom if trading dips, and a far easier conversation with a lender. It also signals commitment, and lenders read commitment as lower risk. The counter-argument is opportunity cost: cash sunk into one business can't be spread across two, and it can't absorb a renovation or a marketing push the business might need more than it needs a bigger deposit. There's no universal right answer. The honest version is that you size your cash contribution against how confident you are in the numbers and how much reserve you need to sleep at night.

One thing to be clear-eyed about: buying with little or no cash of your own is possible, but it's the exception, it narrows your options sharply, and it usually means leaning hard on seller finance or an earn-out. We've laid out exactly how that works, and where it falls down, in how to buy a business with no money in the UK. For everyone else, cash is the starting block, and the more of it you bring, the more of the rest of this article is available to you.

A bank acquisition loan is a term loan a lender advances specifically to buy a business, repaid over a fixed period out of the business's future profits. It's the workhorse of UK acquisition finance, and for any deal above the small-ticket end it's likely to be the largest single piece of your funding.

These loans come in two broad flavours. A secured loan is backed by an asset the lender can take if you default, usually commercial property, plant and machinery, or your own home through a personal guarantee. Because the lender's risk is lower, secured borrowing is cheaper and you can borrow more against it. An unsecured loan has no specific asset behind it, so it's smaller, dearer, and the bank leans harder on the strength of the cash flow and your track record. Most SME acquisition packages are a mix: a chunk secured against the trading assets, topped up with something unsecured, and very often a personal guarantee from you on top regardless.

What an acquisition loan costs

Pricing on a business acquisition loan is almost always the Bank of England base rate plus a margin the lender sets according to risk. The base rate is the anchor, so it pays to know where it sits. As of the April 2026 decision the Bank of England held Bank Rate at 3.75%, down from the highs of 2023. On top of that base, a lender might add anywhere from two to six percentage points depending on the deal, the security and you, so a real-world acquisition loan in 2026 often lands somewhere in the high single digits to low teens. Rates move, margins vary by lender, and a strong deal with good security prices keener than a thin one, so treat any single number as indicative and get quotes.

The repayment term usually runs three to seven years, sometimes ten if there's property in the mix. Shorter terms mean higher monthly payments but less interest paid overall; longer terms ease the monthly burden but cost more across the life of the loan.

The bank isn't lending against the price you agreed. It's lending against the cash the business throws off after you've paid yourself. Get a loan sized to your ambition rather than the cash flow, and the first slow quarter does the rest.

The lender will size the loan so the business can comfortably cover the repayments out of its normalised profit with room to spare, which brings us to the part buyers underestimate most: the bank cares less about the price you've agreed and more about whether the business can repay. We come back to exactly how lenders assess a purchase further down, because getting that right is what turns a no into a yes.

Government-backed schemes are funding routes where the state either lends to you directly or guarantees part of a commercial lender's loan, lowering the lender's risk so they'll say yes to deals they might otherwise decline. For UK buyers there are two that genuinely matter when you're working out how to finance buying a business, and both are run through the British Business Bank.

Start Up Loans for buying a business

The first is the Start Up Loans programme. It's a government-backed personal loan, not a business loan, which means it isn't credit-checked against the company you're buying and there's no asset security required. You can borrow between £500 and £25,000 at a fixed 6% per year over one to five years, per the Start Up Loans scheme. Several partners in the same business can each apply, taking a single business up to £100,000. And yes, despite the name, you can use it to buy an existing business: the scheme explicitly covers purchasing a business you haven't owned for more than 36 months, provided you supply the target's financial accounts with your application. For a sub-£100k deal, two co-buyers each drawing a Start Up Loan can fund a meaningful slice of the price at a fixed rate that often undercuts commercial unsecured lending, with free mentoring thrown in. It's one of the most underused tools at the small end of the market.

The Growth Guarantee Scheme

The second is the Growth Guarantee Scheme, the successor to the Recovery Loan Scheme. Here the government doesn't lend to you; it backs the lender. The scheme provides accredited lenders with a 70% government guarantee on facilities of up to £2m, according to the British Business Bank, which can be used for legitimate business purposes including acquisition. You apply to an accredited lender as normal, but the guarantee makes the lender far more willing to back a deal where your security is a bit thin. It doesn't change the fact that you still have to repay every penny, and you'll typically still give a personal guarantee, but it widens the door for buyers who'd otherwise be turned away on collateral grounds.

Neither scheme is free money, and neither removes the need for a credible plan and accounts that stack up. What they do is shift the risk balance enough that lenders fund deals they'd flinch at unguaranteed. If your deal is small, look hard at Start Up Loans first. If it's larger and your sticking point is security, ask any lender you approach whether they're accredited for the Growth Guarantee Scheme.

Seller financing is when the person selling the business agrees to take part of the price later instead of all of it on day one. In effect, the seller becomes one of your lenders. It's the most powerful and most overlooked lever in a UK acquisition, and on smaller owner-managed deals it's often the difference between a purchase that completes and one that stalls because you couldn't close the funding gap.

There are three common forms, and they're worth keeping distinct.

Deferred consideration is the simplest: you pay an agreed amount up front and the rest in instalments over an agreed period, usually one to three years, often with interest. The price is fixed; only the timing moves. It eases your cash and borrowing needs and it keeps the seller mildly invested in a clean handover, because they're not fully paid until the schedule runs out.

An earn-out ties a portion of the price to the business's actual performance after you take over. You pay a base figure at completion, then further payments only if the business hits agreed targets: revenue, profit, customer retention, whatever you both sign up to. Earn-outs do two useful things at once. They reduce your day-one funding, and they protect you against the seller having dressed up the numbers, because if the business underperforms once they've gone, you simply pay less. They also keep a departing owner motivated through the transition. The catch is that earn-outs are fiddly to draft and a fertile source of disputes, so the metrics have to be defined tightly and the seller's ability to influence them after they leave has to be pinned down.

Vendor loan notes are a more formal version of deferred consideration, where the seller's deferred amount is documented as a loan with its own terms, interest and security ranking. Larger deals lean on these.

Why would a seller agree to any of this? Sometimes because it's the only way to get their asking price when buyers can't fully fund it. Sometimes for tax reasons. Often because a seller who believes in the business is happy to back that belief, and a buyer who asks for seller finance is implicitly asking the seller to vouch for their own numbers.

A seller who flatly refuses any deferral or earn-out, on a business they swear is rock solid, is telling you something. If the numbers are as good as the pitch, why won't they wait for a slice of the money the business is about to make?

That point cuts both ways, and it's worth pressing on. Pair any seller-funded structure with proper due diligence, because the warranties and the earn-out terms are where the findings from your checks turn into contractual protection.

Asset finance and invoice finance are funding routes secured against specific things the business owns or is owed, rather than against the business as a whole. They rarely fund an entire acquisition on their own, but they're brilliant for plugging part of the price or freeing up cash so your main loan doesn't have to stretch as far.

Asset finance lets you borrow against, or spread the cost of, physical kit: vehicles, machinery, equipment, IT. If the business you're buying owns valuable assets outright, a lender will often advance money against them as part of the deal, which can release a useful slug of funding at a rate that reflects the security those assets provide. The two common structures are a hire-purchase arrangement, where you pay in instalments and own the asset at the end, and a finance lease, where you rent it. For asset-heavy businesses (a haulage firm, a manufacturer, a plant-hire operation), asset finance can carry a surprisingly large share of the purchase, because the security is tangible and easy for a lender to value.

Invoice finance advances cash against the business's unpaid invoices. If the company you're buying sells on credit terms and is routinely owed, say, £80,000 by customers at any one time, an invoice finance facility can advance most of that book to you, typically up to around 85% to 90% of the invoice value, turning slow-paying debtors into immediate working capital. There are two flavours: factoring, where the finance provider also chases the invoices, and discounting, where you keep collecting and the funding stays confidential. For a buyer, invoice finance is less about funding the purchase price and more about solving the working-capital problem that often comes with it, so you're not borrowing your acquisition loan and then immediately scrambling for cash to pay suppliers in month one.

The smart move is to think of these as part of the stack rather than the whole answer. Fund the bulk of the price with a deposit, an acquisition loan and maybe some seller finance, then use asset finance to release value from the kit and invoice finance to cover the cash-flow gap. That layering is exactly how experienced buyers keep their own cash commitment down without over-relying on a single expensive loan.

Equity finance means raising money by selling a share of the business to an investor, rather than borrowing it. You don't repay equity the way you repay a loan; instead the investor owns a slice of the company and shares in its future profits and value. For most first-time UK buyers equity is a minority route, but it earns its place when the deal is too big for debt and your cash alone, or when you'd rather share the risk than carry it all yourself.

The simplest form is an angel investor or a partner: an individual who puts cash into the purchase in exchange for a stake. This is common in small acquisitions, where a buyer with operating skill teams up with someone who has capital. It can work beautifully, and it can also turn sour fast if you haven't agreed in writing who decides what, how profits are split, and what happens if one of you wants out. Get a shareholders' agreement drafted before any money moves, not after the first disagreement.

At the larger end sit private equity and search funds. A search fund is a vehicle where investors back an individual specifically to go and find, buy and then run a single business. It's increasingly popular among MBA-types who want to own rather than be employed. Private equity proper tends to look at deals well above the typical SME ticket, and brings money, governance and pressure in roughly equal measure. Both are real routes, but they reshape the deal: you'll likely end up running the business for investors rather than purely for yourself, with reporting obligations and a planned exit baked in from day one.

The trade-off with all equity is ownership. Debt is expensive in interest but you keep the whole business once it's repaid. Equity costs you no monthly repayment, but it costs you a permanent share of everything the business is ever worth, which on a business that does well is by far the more expensive option in the long run. That's why most buyers reach for equity only to bridge the gap that debt and cash can't cover, and keep it as small as the deal allows. If you're weighing whether to buy at all, the broader picture sits in our guide to how to buy a business in the UK in 2026.

When a lender assesses finance to buy a business, they're answering one question above all others: will the business generate enough cash to repay this loan after the buyer has paid themselves and the bills? Everything in their decision flows from that. Understand what they look at and you can build an application that gets a yes instead of guessing why you got a no.

The central number is debt-service cover: the business's profit available to service debt, divided by the loan repayments. Lenders want a clear margin of safety, commonly looking for profit that covers the repayments comfortably rather than just scraping them. They work this off normalised profit, not the headline figure in the accounts. That's the same normalisation work that drives valuation: adding back the seller's personal costs and one-offs, stripping out anything that won't recur. If you don't know your target's normalised EBITDA cold, you're not ready to approach a lender, and the same numbers you'll need are the ones a buyer should already be pulling out during due diligence.

Beyond the cash-flow test, lenders weigh a familiar checklist:

• Your deposit and skin in the game. The more of your own money is committed, the lower their risk and the better your terms.
• Security available. Property, plant and equipment, and a personal guarantee. More tangible security means more borrowing at a lower rate.
• Your experience and credit history. A buyer with relevant sector experience and clean personal credit is a safer bet than a first-timer with no track record in the field.
• The quality and durability of the business's earnings. Recurring revenue, a spread of customers and a defensible market all reassure a lender. Customer concentration and lumpy one-off income worry them.
• The deal structure. A purchase with some seller finance or an earn-out signals that the seller backs their own numbers, and lenders read that as a positive.

The practical upshot is that the loan is sized to the business, not to the price you fancy paying. If the cash flow only supports a smaller loan than the gap you need to fill, you've got three moves: put in more cash, persuade the seller to defer more of the price, or renegotiate the price down. The business plan you hand the lender should connect all of this: the normalised numbers, your deposit, the security, your experience, and a clear-eyed account of the risks and how you'll manage them. Lenders fund prepared buyers. The vague ones get the cautious no that UK Finance's resilient-but-careful market is full of.

The deposit is the share of the purchase price you fund from your own money up front, and it's the single figure most first-time buyers want pinned down. There's no statutory minimum, because no two deals are identical, but there are realistic working ranges, and knowing them stops you wasting months chasing businesses you were never going to fund.

As a rough rule for UK SME acquisitions, expect to put in somewhere between 10% and 50% of the purchase price as cash, with most lender-funded deals clustering around the 20% to 40% mark. Where you land inside that range depends on the same factors a lender weighs. A business with strong, steady cash flow and tangible assets to secure against can be bought with a smaller deposit, because the lender's risk is lower. A business with thin margins, lumpy income or few assets will need you to put in more, sometimes a lot more, before anyone will lend against the rest.

A few specifics worth holding in your head:

• Heavily asset-backed deals can need less cash, because asset finance and secured lending do more of the lifting. A buyer purchasing a business that owns its premises or a fleet of vehicles may get away with a lighter deposit.
• Service businesses with little to secure against tend to need more, because the lender has nothing tangible to fall back on and leans harder on your contribution and the cash flow.
• Seller finance can substitute for part of the deposit. If the seller defers 20% of the price, that's 20% you don't need on day one, which is exactly why seller-funded structures matter so much at the smaller end.
• Keep a reserve on top of the deposit. The deposit isn't the whole of your cash requirement. Budget for legal and accounting fees, stamp duty where it applies, and several months of working capital, because an acquired business almost always needs feeding before it starts feeding you.

Don't chase the lowest possible deposit as if it were a prize. Stretch to the minimum, borrow the maximum and keep nothing back, and you've bought a business with no margin for the first bad month. There's always a first bad month.

The comfortable deposit is the one that leaves the repayments serviceable and your nerves intact. If your cash genuinely won't reach a workable deposit on the deals you want, that's the signal to read how to buy a business with no money in the UK and lean into seller finance, rather than to over-borrow into a deal that can't breathe.

There's no single best way to fund an acquisition. The right answer is a blend chosen to fit the specific deal, your cash position and the business's ability to repay. Experienced buyers don't ask "which one source?" They ask "what stack gets this done at the lowest cost and risk I can live with?" Here's how the main routes compare so you can build that stack deliberately.

Finance type	Typical use	Deposit / cost	Pros and cons
Cash / personal funds	The deposit and reserve under every deal	Your own money; no interest, but real opportunity cost	Cheapest and strongest signal to lenders; ties up capital and can't be spread across deals
Bank acquisition loan	The largest piece on most mid-sized deals	20% to 40% deposit; base rate (3.75%) plus a margin	Big firepower, repaid from profits; needs strong cash flow, usually a personal guarantee
Start Up Loans	Small deals, up to £25k each (£100k per business)	No security; fixed 6% over 1 to 5 years	Cheap, unsecured, mentoring included; capped low, personal liability
Growth Guarantee Scheme	Larger deals where your security is thin	Via accredited lender; 70% govt guarantee to lender	Unlocks loans security alone wouldn't; you still repay it all and usually guarantee it
Seller financing / earn-out	Bridging the gap, aligning the seller	Lower day-one cash; price deferred or performance-linked	Reduces funding and protects against dressed-up numbers; complex to draft, dispute-prone
Asset finance	Releasing value from kit and vehicles	Secured on the assets; rate reflects security	Good firepower on asset-heavy deals; only as big as the assets
Invoice finance	Working capital, not the price itself	Advances ~85% to 90% of the debtor book	Solves the cash-flow gap; costs scale with use, less relevant if you sell for cash
Equity / investors	Gaps debt and cash can't cover; large deals	No repayment; you give away a permanent share	No monthly burden; most expensive long-term, you cede control and upside

The way to use this is to start from the deal and work backwards. Take the price, subtract the cash you can comfortably commit while keeping a reserve, and you've got the gap to fund. Fill the biggest part of that gap with the cheapest borrowing the business can service, usually a bank acquisition loan, sized to the cash flow, not your ambition. Then close whatever remains with the routes that fit the business: seller finance to align the vendor and reduce your day-one outlay, asset finance to release value from the kit, a Start Up Loan or two on a small deal, the Growth Guarantee Scheme if security is your sticking point, and equity only when debt and cash genuinely can't reach.

Knowing how to finance buying a business well is mostly knowing how to layer these so no single source is over-stretched and the monthly repayments leave the business room to breathe. Get the structure right and the deal funds itself out of the profits you've bought; get it wrong and you'll spend year one servicing debt instead of running a business. When you're ready to put a real price against these numbers, browse businesses for sale on NewOwner and build the stack against an actual listing. If you want the search tools, alerts and saved listings to do it properly, the Buyer plan is built for exactly this. Before you firm up any offer, run the target through a proper due diligence checklist, because your funding structure and what you find in the books have to agree with each other.
