Valuation Basics
Plain-English guides to the methods, multiples, and adjustments that determine what a UK SME is really worth.
Most owners only sell or value a business once or twice in their working life. These guides give you the foundations: how valuers actually build a number, why two businesses with the same profit can be worth very different amounts, and what to look at before you trust any figure on a calculator screen.
How UK SMEs are valued in practice
For owner-managed businesses with profits between £100k and £5m, valuation almost always starts with adjusted EBITDA multiplied by a sector and risk-adjusted multiple. We strip out owner remuneration above market rate, one-off costs, and any non-trading items to arrive at a maintainable earnings figure a buyer would actually inherit.
Discounted cash flow is layered in when growth is non-linear or capital expenditure is heavy. Asset-based methods anchor the range for property-rich, investment, or wind-down scenarios. The number that lands in the report is rarely from one method alone, it is a cross-check between two or three.
What moves the multiple
Recurring revenue, customer concentration, owner dependency, and quality of management team all shift the multiple by full turns up or down. A £1m EBITDA business with 40% recurring revenue and a deputy MD in place can trade at 6 to 8x. The same earnings with one customer at 45% and the founder doing every quote drops to 3 to 4x.
Sector matters, but discipline matters more. We benchmark against completed UK deals in your size band and sector, not headline figures from US tech transactions that have no bearing on a Midlands engineering firm.
When a calculator is not enough
Instant calculators apply a flat sector multiple to last year's profit. They are useful for orientation, never for a decision. Real valuations adjust earnings, weight risk, and stress-test against deal data.

Frequently asked questions
What is the most common UK SME valuation method?
Adjusted EBITDA multiple, cross-checked against discounted cash flow and a sector deal benchmark. For investment or property-heavy businesses we lead with net asset value instead.
Are online valuation calculators accurate?
They give a rough orientation, usually within plus or minus 40%. They do not adjust earnings, weight customer concentration, or reflect current UK deal multiples, so they should never replace an adviser-led range.
How much does an indicative valuation cost?
Our indicative range is free and confidential. A formal written report for HMRC, court, EOT, or shareholder evidence is quoted on the day, typically £2,500 to £7,500 depending on complexity.
What information do I need to share to get started?
Three years of statutory accounts and a short conversation about ownership, customer mix, and your reason for asking. We work to a strict NDA and never approach buyers without permission.
