Startup valuation methods in the UK: 5 approaches for first-time founders
Five startup valuation methods used in UK pre-seed and seed rounds, with HMRC share valuation rules, EIS advance assurance and founder-friendly checks.
What to take away
- UK valuations have two audiencesthe investor who signs the term sheet and HMRC, which decides whether the price supports EIS or SEIS relief.
- Five methods cover most pre-seed and seed rounds: scorecard, comparable transactions, pre-revenue milestone, discounted cash flow and a relief-driven ceiling.
- Most first rounds settle on a range, because relief caps and dilution limits pull against the founder's headline number.
- A valuation is not a price until the term sheet and the articles agree, and later rounds reset the reference point.
- Record the method, the inputs and the date.
Why UK tax rules shape the number
In the UK, the price an angel pays is tied to the reliefs they can claim. The conditions for both schemes sit in the Income Tax Act 2007, and the subscription price must satisfy them at the date shares are issued.
Founders who want certainty before a raise can seek EIS advance assurance, which reviews the company, its shares and the proposed price. The route to apply for the Enterprise Investment Scheme sets out what HMRC expects to see.
The application asks for the business plan, financial forecasts, details of the share class and how the money will be used.
Relief limits cap what can be raised under each scheme, so a SEIS round and a later EIS round rarely share one price. SEIS and EIS compared sets out which relief fits which stage.
For shares issued in the 2025/26 tax year, SEIS allows up to £250,000 per company. EIS allows up to £5m a year and £12m over the company's life. HMRC's guidance is current for that tax year.
Five methods you can compare
Works best when
- Scorecard
- Pre-revenue, no comparables
- Comparable transactions
- Similar UK rounds are public
- Pre-revenue milestone (Berkus style)
- Idea stage with a credible team
- Discounted cash flow
- Revenue exists and forecasts are testable
- Relief ceiling
- Investors are claiming EIS or SEIS
Main weakness
- Scorecard
- Weightings are subjective
- Comparable transactions
- Private prices are rarely disclosed
- Pre-revenue milestone (Berkus style)
- Rewards optimism over traction
- Discounted cash flow
- Small assumption changes move the answer
- Relief ceiling
- Ties price to scheme limits, not demand
Founders should treat the result as a range. Two methods that disagree by a wide margin are telling you the assumptions need work, not that one method is wrong.

A worked pre-seed example
Worked pre-seed example
- £300,000cash needed
- £1.2mpre-money valuation
- £1.5mpost-money valuation
- 20%new money buys
Start with the comparable transaction view. Beauhurst tracks UK equity deals. Its typical pre-seed pre-money range is £1m to £2m. Use £1.1m as the base case.
Apply a scorecard with these weights: team 40 per cent, market 35 per cent, product 25 per cent. Score each factor against the average. Team 1.2, market 1.0, product 1.3. The weighted score is (1.2 x 0.40) + (1.0 x 0.35) + (1.3 x 0.25) = 1.155. Applied to £1.1m gives £1.27m.
A DCF with a 40 per cent discount rate on three years of forecasts returns £800,000 to £1.3m. The methods together give a pre-money range of £900,000 to £1.4m.
Now test the range. A scorecard built on team, market and product might return £900,000 to £1.4m. A comparable transaction view might sit lower. If both land near £1.2m, the term is easy to defend.
Add the dilution and relief angle. Raising £300,000 at a £1.5m post-money valuation leaves the founding team with 80 per cent before any option pool. Push the pre-money to £1.8m and the same £300,000 buys 14.3 per cent.
| Raise | Pre-money | Post-money | Investor share | Founder share |
|---|---|---|---|---|
| £300,000 | £1.2m | £1.5m | 20.0% | 80.0% |
| £300,000 | £1.8m | £2.1m | 14.3% | 85.7% |
The SEIS limit of £250,000 means a £300,000 round cannot sit entirely under SEIS.
Choosing a method: a five-step sequence
Choosing a method
- Set the cash need first. A £300,000 requirement and a £750,000 requirement imply different prices.
- Pick two methods, not one, and run both on the same inputs.
- Check the relief position before you name a number.
- List the assumptions with dates, including the option pool and any convertible notes in the UK still outstanding.
- Agree a range with the lead investor, then let the term sheet fix the number.
When the round includes a crowd
Some UK founders price a round publicly through equity crowdfunding, where the platform shows a pre-money figure to retail investors. The FCA's guidance for consumers on crowdfunding sets out the risks those investors are told to weigh.
The FCA's consumer crowdfunding guidance sits on top of rules that took effect in April 2014.
A public price is harder to revise later. Founders who set one should hold back a buffer for the costs of the raise itself, from platform fees to legal review.
Setting a range you can defend
Write the valuation as a range with a floor and a ceiling. The floor is the price at which the round funds the plan. The ceiling is where a higher number starts to strain the next round.
Keep the evidence in one place: the method, the inputs, the comparables and the relief checks. A founder who can explain the number in five minutes will spend less time relitigating it during due diligence.
Common questions
How do I value a UK startup with no revenue?
Start with a scorecard or a milestone method, then check the answer against the relief position. Pre-revenue companies rarely have comparables, so the method matters less than the evidence behind it.
Does an EIS or SEIS valuation need HMRC approval?
There is no approval of the price as such. Advance assurance confirms that HMRC is likely to accept the company and the shares, which is why founders ask before issuing them.
What is the difference between pre-money and post-money valuation?
Pre-money is the value of the business before new money arrives. Post-money adds the investment, and the new investor's percentage is the raise divided by the post-money figure.
Can two valuation methods give different answers?
Yes. The gap shows which assumptions are doing the work, so revisit the plan rather than averaging the results.
