Valuation multiples
How much is a UK business worth?
Most UK SMEs are valued on a multiple of adjusted profit: SDE for smaller owner-operated businesses, and EBITDA for larger, manager-run companies. Typical ranges sit around 2-6× depending on sector, size, recurring revenue and owner dependency.
SDE
Seller's Discretionary Earnings
Owner-operated businesses. Adds owner salary and perks back to profit.
EBITDA
Earnings before interest, tax, D&A
Manager-run companies. More common above about £1m profit.

Value drivers
What drives your valuation up or down
Recurring revenue
LiftContracts, subscriptions and repeat fees support higher multiples than one-off project work.
Customer concentration
DragA broad client base is lower risk; heavy reliance on one or two customers pulls the range down.
Owner dependency
DragBusinesses that run without the owner day to day attract more buyers and stronger prices.
Trading history and growth
LiftA clear track record and rising earnings usually lift the multiple versus flat or declining results.
Margin quality
LiftSustainable, well-documented margins matter more than headline turnover alone.
Selling and tax
Tax when you sell your business
Capital Gains Tax usually applies to the gain when you sell. Many owners qualify for Business Asset Disposal Relief, which charges a reduced CGT rate on qualifying gains up to a £1m lifetime limit. Rates change, so confirm the current rate on GOV.UK or with an accountant.
