UK Business Valuation Methods

1. Bottom line up front

A defensible UK SME business valuation in 2026 is the output of two or three methods applied in parallel and triangulated against each other, not a single number produced by one formula. The six methods that account for the vast majority of professional opinions are the EBITDA multiple, discounted cash flow, comparable transactions, asset-based net realisable value, capitalised maintainable earnings, and entry cost. Each has a defined set of conditions under which it is the appropriate primary method, and each has structural blind spots that the others are used to correct.

For profitable owner-managed businesses in the **£500,000 to £3 million EBITDA** band, the EBITDA multiple is the headline method in roughly **85% of cases**, with comparable transactions as the primary cross-check and DCF used selectively where contracted future cash flows justify it. Asset-based approaches dominate for property-heavy holding companies and orderly wind-downs. Capitalised earnings is the choice where profits are stable and predictable but growth is flat. Entry cost is reserved for early-stage or replicable businesses where a buyer's alternative is to rebuild the platform from scratch.

The choice of method matters because each can produce a defensible result that differs from the others by **20% to 40%** on the same business. A valuer who runs only one method is presenting a number, not a valuation. A valuer who triangulates, discloses the working, and explains why each method weighted as it did is presenting an opinion that holds up in front of HMRC, courts, trustees, buyers, and shareholders. This guide covers each of the six methods, when to use them, and the eighteen-month process by which a serious valuation is constructed and refreshed.

2. The structural surveyor analogy

A serious structural survey on a commercial building is not done with one instrument. The surveyor uses a damp meter, a thermal camera, a borescope, calibrated drawings, and a physical inspection by hand and eye. Each instrument has a job. The damp meter quantifies moisture but tells you nothing about the brickwork above the damp-proof course. The thermal camera reveals cold bridges but cannot see structural movement. The drawings reveal the design intent but cannot show what twenty years of occupation has done to the fabric. Only when the readings from all five sources are laid on top of each other does the building's actual condition emerge.

Business valuation works the same way. An EBITDA multiple tells you what the cash flow is worth at today's market clearing price. A DCF tells you what the same cash flow is worth if you make a defined set of forecast assumptions about its trajectory. Comparable transactions tell you what real buyers have actually paid in the recent past. Asset-based methods tell you what the business is worth if the cash flow stops tomorrow. Each instrument has a job. The professional opinion lives in the overlay, not in any single reading.

3. The six methods and the construction blueprint

Below is the comparative framework we use in every UK SME engagement. The table sets out each method's primary use case, its typical 2026 application, and its principal blind spot.

The six methods at a glance

The eighteen-month construction blueprint

For owners using a valuation as the foundation of an exit, refinancing, or shareholder transaction, the methodology runs on an eighteen-month cycle. Below is the standard sequence.

Anonymised case study

Drawing from our aggregate transaction data at BusinessValuation.co.uk, a West Midlands specialist distribution business with reported EBITDA of **£1.1m** approached us for a refinancing valuation. A single-method EBITDA-multiple opinion at the sector median (4.8x) would have returned **£5.28m**. We ran the full triangulation. Normalisation added **£140,000** to maintainable EBITDA (above-market director salary and related-party rent), lifting the base to **£1.24m**. The EBITDA multiple method, calibrated to four recent sub-sector comparables in the £900k to £1.4m EBITDA band, produced **£6.32m** at 5.1x. The DCF, built on the company's existing three-year contracted revenue stream and a WACC of 11.5%, produced **£6.85m** with terminal value contributing 62% of the total. Comparable transactions produced a range of **£5.9m to £6.7m**. The asset-based check (£2.1m of net assets) confirmed a value floor well below the earnings-based range. The final triangulated opinion was **£6.4m**, weighted 50% to EBITDA multiple, 30% to DCF, 20% to comparable transactions. The lender's own valuer subsequently arrived at **£6.25m** using the same triangulated approach, validating the methodology.

4. How method choice changes the headline number

Method choice is not a cosmetic decision. On the same business, with the same data pack, different methods can produce defensible numbers that differ by **20% to 40%**, and the choice between them is where most valuation disputes originate.

EBITDA multiples reflect what the market is paying today. The method is calibrated to recent comparable transactions and tracks live deal-flow data. It is the most relevant method for businesses that will actually transact in the near term, because it answers the only question that ultimately matters in a sale: what will a buyer pay. Its weakness is that it can be distorted by a strong or weak trading year and is highly sensitive to how EBITDA is normalised.

DCF reflects what the cash flow is worth on the valuer's forecast assumptions. It can produce a higher number than the multiple method where the business is on a credible growth trajectory or has contracted revenue extending well beyond the current year. It can produce a lower number where margins are under structural pressure or capex requirements are about to rise sharply. The terminal value typically contributes **50% to 70%** of the total, so the method is only as robust as the assumptions feeding the terminal calculation. A DCF with hidden optimism in the terminal growth rate is a number, not a valuation.

Comparable transactions ground the opinion in real-world deal flow. The method is the primary cross-check on every other approach and the headline method where sector deal flow is dense enough to support it. The work is in the comparable selection. Twelve to twenty observations from genuinely similar businesses is the working minimum. Fewer than that and the range is too wide to be useful. Outliers must be examined, not averaged out, because the structural reason for an outlier is often the most informative part of the data set.

Asset-based and capitalised earnings methods set the floor and the steady-state value. Neither is the right primary method for a growing trading SME, but both are essential cross-checks. The asset-based method tells you what the business is worth in the worst case if the earnings stop. The capitalised earnings method tells you what the current earnings stream is worth as a perpetuity at no growth. Together they bracket the range within which the multiple and DCF methods should sit, and they expose the moments when one or other of those primary methods has drifted into wishful thinking.

The right number is the one produced by a transparent triangulation, with method weightings disclosed and the reasons for divergence between methods explained. A valuation that does that is defensible in front of any audience. A valuation that does not is a marketing document.
