Most buyers finance a UK business acquisition using a combination of personal funds, a commercial loan, and sometimes seller finance or a government-backed loan. Very few deals are funded by a single source — understanding the options and how they stack together is the starting point.
Quick Answer
To finance buying a UK business you typically combine personal capital (cash savings, equity release, pension funds) with a commercial loan — either a standard business acquisition loan or a government-backed scheme such as the British Business Bank's Growth Guarantee Scheme. Seller finance and earn-outs can bridge gaps in funding. Working capital must be budgeted separately from the purchase price.
In short:most lenders expect buyers to contribute 30–50% of the purchase price personally. The rest can be funded through lending, seller finance, or a combination. No-money-down deals are rare and usually involve significant seller concessions.

How business acquisition finance works
Buying a business is not like buying a house. There is no straightforward mortgage product, no standardised lending criteria, and no automatic access to government-backed schemes for every deal. Lenders assess each transaction individually, based on the business's financial performance, the buyer's background and financial position, and the structure of the deal.
Most UK business acquisitions in the SME market are funded through a combination of sources — a "funding stack" — rather than a single loan. Understanding each component, what it costs, and what lenders expect from you personally is the foundation of financing a deal successfully.
Key costs to budget for:
Purchase price - Agreed sale price for the business
Upfront personal contribution - Typically 30–50% of purchase price
Working capital reserve - Cash to run the business from day one
Legal fees (buyer) - Solicitor costs — typically £2,000–£8,000+
Accountant / due diligence - Typically £1,500–£5,000+
Broker or adviser fees - If applicable
Stamp Duty (share purchases) - 0.5% of share consideration
SDLT (property) - If real property transfers — rates depend on type and value
Lender arrangement fees - Typically 1–2% of loan value
Loan interest - Ongoing cost — factor into affordability
Personal funds and equity
Most lenders require a meaningful personal contribution from the buyer — typically 30–50% of the purchase price. This demonstrates commitment, reduces the lender's risk exposure, and confirms the buyer has personal financial capacity.
Cash savings
The most straightforward form of personal contribution. Lenders will want to see that the funds have been held for a period of time and are not borrowed.
Equity release from property
Homeowners can remortgage or release equity from residential or commercial property to fund part of a business acquisition. This is a common route for first-time buyers who have built equity in their home. The risk is that your home or property secures the funding — if the business fails, the property is at risk.
Personal assets
Vehicles, investments, savings accounts or other personal assets can form part of the personal contribution. Lenders may discount the value of illiquid assets.
Director loans from an existing business
If you already own another business, you may be able to extract funds from that company by way of a director loan to fund a new acquisition. This needs to be structured carefully for tax purposes — seek advice from your accountant.
Commercial business acquisition loans
Business acquisition loans are the primary lending product for SME acquisitions in the UK. They are provided by high street banks, challenger banks and specialist SME lenders.
How they work
The lender assesses the business being acquired (its trading history, profit, assets and lease) alongside the buyer's background and ability to service the debt. If approved, the loan is typically repaid over three to seven years, with interest charged at a rate reflecting the risk profile of the deal.
What lenders typically offer
Loan amounts: Typically 50–70% of the purchase price, up to £5 million for the right transaction
Loan term: Three to seven years is typical; property-backed deals may be longer
Interest rates: Usually between 6% and 12% for SME acquisitions, depending on risk, security and current base rate
Security: Lenders may require a personal guarantee, a debenture over the business assets, or a charge over property
Repayment: Monthly principal and interest repayments
What the lender needs from you
A business plan explaining how you will run and grow the business
Three years of accounts for the business being acquired
Bank statements for the business (12–24 months)
Your personal financial statement (savings, income, liabilities)
Proof of personal contribution
Due diligence and heads of terms (once in process)
Your CV demonstrating relevant experience
Which lenders to approach
High street banks (Lloyds, Barclays, NatWest, HSBC, Santander) all offer business acquisition lending, but criteria and appetite vary. Challenger banks (Funding Circle, Shawbrook, Aldermore, OakNorth) are often more flexible and may respond more quickly. Specialist SME lenders and commercial finance brokers can help identify the best match for your specific deal.
A commercial finance broker can approach multiple lenders simultaneously and is often worth using for acquisitions above £100,000 — their fee is usually paid by the lender rather than you.
Government-backed lending schemes
The British Business Bank oversees several schemes that can support business acquisitions. These do not provide funds directly — they guarantee part of the loan to the lender, which reduces risk and can make approval more achievable.
Growth Guarantee Scheme (GGS)
The Growth Guarantee Scheme (successor to the Recovery Loan Scheme) provides a government-backed guarantee to lenders on eligible loans. In 2026, loans of up to £2 million are available through accredited lenders. The guarantee is to the lender, not the borrower — you still repay the full loan and remain personally liable for it.
Key features:
Loans from £25,001 to £2 million
Terms of up to six years
Available for acquisitions, refinancing, investment and working capital
Must be delivered through an accredited lender
The 70% government guarantee reduces lender risk, which can mean lower rates or more flexible criteria
Check the British Business Bank website (british-business-bank.co.uk) for the current list of accredited lenders and up-to-date scheme eligibility criteria.
Start Up Loans
The British Business Bank's Start Up Loans scheme offers personal loans of up to £25,000 per director (up to £100,000 in total across co-founders) at a fixed 6% interest rate. These are personal loans, not business loans, and are typically used for smaller acquisitions or to fund a personal contribution alongside other lending.
Start Up Loans are available for businesses trading for under three years. Acquiring an existing business can sometimes qualify as a start-up — check eligibility with the Start Up Loans Company.
Seller finance
Seller finance (also called vendor finance or deferred consideration) is where the seller agrees to receive part of the purchase price over time — essentially lending you part of the price rather than requiring full payment at completion.
How it works
Example: A business is agreed at £300,000. The buyer pays £180,000 at completion (60% funded by a mix of personal funds and bank loan). The seller agrees to receive the remaining £120,000 over three years, paid monthly with interest.
From the seller's perspective, this widens the buyer pool and can help achieve a higher headline price. From the buyer's perspective, it reduces the upfront capital requirement.
What to agree
The amount deferred and the payment schedule
The interest rate on the deferred amount
What security (if any) the seller has over the business or assets during the deferred period
What happens if payments are missed
Whether the deferred amount is linked to business performance (this becomes an earn-out — see below)
Seller finance arrangements must be properly documented in the sale agreement. Both parties should seek legal advice on the terms.
Risks for buyers
If the business underperforms, you may struggle to meet both the bank loan repayments and the seller finance payments. Make sure the combined debt service is realistic against the business's expected cash flow before agreeing the structure.
Earn-out structures
An earn-out links part of the purchase price to the future performance of the business after completion. The buyer pays a base price at completion and additional payments if defined targets are met.
When earn-outs are used
Where the seller's figures include future projections the buyer wants to verify
Where there is a key customer or contract whose renewal is uncertain
Where the buyer and seller cannot agree on a price because of different views on future performance
How earn-outs are structured
Example: Base price of £250,000 at completion, plus up to £75,000 over two years if annual turnover exceeds £400,000 per year.
Earn-outs require very precise contractual drafting. The key issues to resolve are:
How is the performance metric calculated — and who decides?
What happens if the buyer makes changes that affect performance?
What accounting standards apply to the measurement?
What happens if the seller disputes the calculation?
Earn-out disputes are common. The more precisely the earn-out metric is defined, the less room for disagreement.
Asset finance and invoice finance
Asset finance
If the business being acquired has significant physical assets — machinery, vehicles, equipment — the buyer may be able to refinance those assets immediately after completion to release cash. This can be used to part-fund the acquisition or to free up working capital.
Asset finance (hire purchase, finance lease) uses the assets themselves as security. Lenders will lend a percentage of the asset value — typically 70–80% of current market value for good-quality assets.
Invoice finance
For businesses with significant trade debtors — outstanding customer invoices — invoice finance allows the buyer to advance a percentage of the debtor book immediately. This is not typically used to fund the acquisition itself, but can be a useful source of working capital immediately post-completion.
Private investors and equity funding
For larger acquisitions or businesses with significant growth potential, equity investors — including private individuals, family offices, or small private equity funds — may be willing to co-invest alongside you.
In an equity deal, the investor takes a shareholding in the acquired business in exchange for funding. Unlike a loan, equity does not need to be repaid — but you give up a percentage of future profits and any eventual sale proceeds.
Equity investors typically expect:
A significant return (often 3–5x their investment over three to five years)
Involvement in major decisions
A clear exit route — usually a future sale of the business
Equity is most relevant for businesses above £1–2 million in value with strong growth potential. For straightforward SME acquisitions, equity investors are less common than debt financing.
Pension-led funding
It is possible in certain circumstances to use pension funds to invest in a business acquisition through a Small Self-Administered Scheme (SSAS). This is a specialist area with complex rules and significant regulatory requirements.
SSAS pension-led funding is not straightforward and is not appropriate for all acquisitions. If you are considering this route, you must take specialist independent financial advice from an adviser regulated by the FCA with SSAS experience before proceeding.
Working capital — the cost most buyers forget
Working capital is one of the most commonly overlooked costs in a business acquisition. It is the cash the business needs to operate day-to-day — to pay suppliers, wages and overheads while waiting for customers to pay.
Even a profitable business can run out of cash if there is a mismatch between when money goes out and when it comes in.
As a new owner, you should budget for:
A cash buffer:Typically one to three months of the business's monthly fixed costs, held in reserve
Stock:If the business holds inventory, you may need to fund a restock at or around completion
Debtors gap:If customers owe money that the seller is taking at completion (standard), you need cash to bridge the gap until the new invoice cycle generates income
Immediate capital expenditure:Equipment that needs replacing, lease dilapidations, IT upgrades
A common rule of thumb is to budget 10–20% of the purchase price as working capital on top of the acquisition cost. This is in addition to your personal contribution to the purchase price — not part of it.
Do not arrive at completion without adequate working capital. Businesses that run out of cash quickly after acquisition often fail — not because they were bad businesses, but because the new owner was undercapitalised.
How lenders assess business acquisition loans
Understanding how a lender thinks helps you present your case effectively.
The business itself
Lenders want to see a profitable, stable business with:
Three years of filed accounts
Consistent or growing revenue
Adjusted EBITDA that comfortably covers the proposed loan repayments — usually a coverage ratio of at least 1.5x to 2x
A defensible lease (enough term remaining to cover the loan period)
Low customer concentration risk
The buyer
Lenders assess:
Relevant industry experience or transferable management experience
Personal financial strength — assets, income, no significant personal debt
Personal contribution to the deal (30–50% is typical)
Credit history — any CCJs, defaults or insolvencies will be a problem
The deal structure
How much is the buyer contributing personally?
Is the price supported by an independent valuation or at least by the accounts?
Is seller finance involved — and if so, how is it ranked relative to the bank loan?
What security is available?
Debt service coverage
Lenders calculate whether the business's adjusted EBITDA can cover the annual loan repayments with headroom. If the business generates £100,000 EBITDA and the loan costs £70,000 per year in repayments — plus you need to pay yourself £50,000 — the numbers do not work. Run this calculation before approaching lenders.
Building your funding stack
Most acquisitions are funded by stacking multiple sources. A typical example for a £400,000 acquisition:
Personal cash/equity - £140,000 - 35% personal contribution
Commercial loan - £180,000 - 45% — bank or challenger lender
Seller finance - £80,000 - 20% deferred over 3 years
Total-£400,000
Separate to this, the buyer would also need working capital (e.g. £40,000–£80,000) held in reserve, plus professional fees of £5,000–£15,000.
The exact split depends on the lender's appetite, the business's cash generation, and what the seller will accept as deferred payment.
Finance preparation checklist
Calculate your maximum personal contribution (cash available without compromising working capital or personal living costs)
Assess any property equity available for release
Check your personal credit history
Prepare a personal financial statement (assets, liabilities, income)
Review the business's three years of accounts and calculate adjusted EBITDA
Calculate annual loan repayment cost at assumed interest rate and confirm it is covered by EBITDA
Budget for working capital separately from the purchase price
Budget for professional fees (legal, accounting, due diligence)
Research the British Business Bank's Growth Guarantee Scheme accredited lenders
Consider using a commercial finance broker for deals above £100,000
Seek independent financial advice before committing to any funding structure
FAQs
Can I buy a business with no money down?
Rarely, and it requires the seller to finance the entire purchase price, which very few sellers will agree to. Most lenders require a 30–50% personal contribution. Some buyers fund the personal contribution through equity release from a property rather than cash savings, which reduces the liquid capital required — but it is not truly "no money."
How much deposit do I need to buy a business?
Typically 30–50% of the purchase price needs to come from you personally. For a £200,000 business, that means £60,000–£100,000 from personal sources plus working capital (another £20,000–£40,000) plus professional fees. Total personal capital requirement is typically 35–55% of the purchase price before professional costs.
Can I use my pension to buy a business?
In limited circumstances, yes — through a SSAS pension structure. This is a specialist route with complex rules, significant setup costs and FCA-regulated advice required. It is not appropriate for all acquisitions. Take qualified independent financial advice before pursuing this option.
Will the lender take a charge over my house?
Commercial loans for business acquisitions often require a personal guarantee, and in some cases a legal charge over personal property. This means your home may be at risk if the business fails and the loan cannot be repaid. Understand exactly what security is required before signing any loan agreement.
How long does it take to arrange acquisition finance?
From initial approach to funds in place, expect six to twelve weeks for a standard SME acquisition. More complex deals, larger loans or government-backed lending may take longer. Start the lending conversation early — ideally at the same time as you begin due diligence.
Should I use a commercial finance broker?
For acquisitions above £100,000–£150,000, a commercial finance broker can add real value — accessing multiple lenders, structuring the application and managing the process. Most brokers are paid by the lender (a procuration fee), so your direct cost is often zero. Check the broker is FCA-regulated.
Do I need a business plan to get acquisition finance?
Yes. Lenders will expect a written business plan covering your background, the business being acquired, why it is a good acquisition, how you plan to run and grow it, and detailed financial projections including debt service coverage. An accountant or finance broker can help you prepare this.
Key takeaways
Most UK SME acquisitions are funded by a combination of personal contribution (30–50%), commercial loan and sometimes seller finance.
Working capital must be budgeted separately from the purchase price — typically 10–20% of the purchase price held in reserve.
The British Business Bank's Growth Guarantee Scheme can support lending through accredited lenders up to £2 million.
Seller finance and earn-outs can bridge funding gaps but must be properly documented with legal advice.
Lenders assess both the business and you personally — relevant experience, personal financial strength and a strong personal contribution all improve your chances.
Calculate debt service coverage before approaching lenders: EBITDA must comfortably cover annual loan repayments, your salary and contingency.
Pension-led funding (SSAS) is possible but complex — specialist FCA-regulated advice is required.
Use a commercial finance broker for larger deals — they can approach multiple lenders and are usually paid by the lender, not you.
