How to Value a Small UK Limited Company

Earnings multiple (the most common SME method)

For a profitable trading company, buyers and lenders most often use a multiple of EBITDA (earnings before interest, tax, depreciation, and amortisation) or EBIT. The multiple reflects the perceived quality and growth prospects of the business — a recurring-revenue software company will command a higher multiple than a single-contract construction firm of identical EBITDA.

Before applying the multiple, accounts are normalised: one-off costs are added back, owner's salary is adjusted to a market rate, and any related-party transactions are restated on arm's-length terms. This normalised EBITDA is the basis on which the multiple is applied.

Net asset value

Net asset value (NAV) — total assets less total liabilities per the balance sheet — is more relevant for asset-intensive businesses (property, plant-heavy manufacturing) or businesses with limited earnings. NAV may be calculated on a book value or a revalued basis, depending on whether assets have been independently appraised. For most trading SMEs, NAV provides a floor rather than a ceiling valuation.

Discounted cash flow

A DCF values the business by projecting future free cash flows and discounting them back to a present value using an appropriate discount rate. It is theoretically robust but highly sensitive to assumptions — small changes in growth rate or discount rate produce large swings in value. DCF is more commonly used as a cross-check than as the primary method in SME transactions, partly because five-year forecasts for small businesses are inherently uncertain.

What reduces a valuation

Buyers and lenders discount valuations for: customer concentration (one client representing more than 20–25% of revenue), key-person dependency, lack of management depth, declining revenue trends, unresolved litigation, and deferred maintenance capital expenditure. Addressing these factors before beginning a sale process materially improves achievable price.
