How to Fund a Business Acquisition in the UK

Buying an existing business in the UK is often faster, lower-risk, and more capital-efficient than building from scratch. But funding the acquisition requires understanding the finance structures available, the documentation lenders need, and how to present the target business's financial performance compellingly.
Valuing the business and setting the acquisition price
Before approaching lenders, you need an agreed or indicative acquisition price. SME business valuations in the UK typically use EBITDA multiples: service businesses with recurring revenue sell at 3-7 times EBITDA; product businesses at 2-5 times; asset-intensive businesses where assets provide underlying value may be valued on NAV or mixed approaches. Understanding the basis of the seller's asking price is important: an inflated multiple requires more debt to fund, which affects servicability.
An indicative valuation from a corporate finance adviser or accountant provides a credible benchmark for both the negotiation with the seller and the lending application. Lenders are less confident in applications where the borrower cannot explain and justify the acquisition price.
Finance structure for different acquisition sizes
For acquisitions under 250,000 pounds: a secured or unsecured business loan against the assets or goodwill of the target business, supplemented by the buyer's equity contribution. Applications are assessed similarly to standard business loans with additional focus on the target's trading performance.
For acquisitions of 250,000 to 2 million pounds: specialist acquisition finance from lenders experienced in SME M&A. Senior debt of 2-4 times EBITDA is typically available, with the management team contributing 20-30 percent equity and vendor finance or mezzanine filling the gap. Full financial due diligence on the target business is typically required.
"The acquisitions that complete on time and at the agreed price are the ones where the finance was lined up before the seller was approached, not after heads of terms were signed."

Documents needed for an acquisition loan
The document set for an acquisition loan includes: the target business's last 3 years of filed accounts and latest management accounts, a heads of terms or draft sale and purchase agreement, the acquirer's own financial information (accounts, bank statements), the management team's CVs and relevant experience, and where applicable a financial due diligence report from an accountancy firm.
Having these documents organised in advance of the first lender meeting dramatically reduces the time from first contact to offer. Acquisition finance often has time pressure (sellers have exclusivity periods), and a slow documentation process can cost the deal.
Structuring the finance to win competitive acquisitions
In competitive acquisition processes (where multiple buyers are bidding), having finance largely confirmed before submitting a bid is a significant advantage. A buyer who can demonstrate committed financing to a seller is a more credible counterparty than one who is 'subject to finance'. Spark Finance can provide a conditional letter of support for acquisition finance that gives sellers confidence in the buyer's financial capability.
Vendor financing is particularly valuable in competitive situations: a seller who accepts 20-30 percent of the consideration as deferred payment signals confidence in the business, makes the deal more deliverable for the buyer (less external debt required), and can actually command a premium price as a result of the certainty it provides.
