UK small businesses are typically valued at a multiple of EBITDA or seller''s discretionary earnings (SDE), with multiples ranging from 1-3x for very small or owner-dependent businesses up to 6-10x for high-quality scaled SaaS or specialist firms. The right multiple depends on the business model, growth, customer concentration, and the buyer type.
This guide explains the main valuation methods, the typical multiples by sector, and what specifically moves the multiple up or down.
The two main methods
Multiple of earnings
By far the most common method for established UK SMEs.
For owner-managed businesses, the relevant earnings figure is usually Seller''s Discretionary Earnings (SDE) — the cash flow available to a single owner-operator. SDE = pre-tax profit + owner''s salary + owner''s benefits + interest + depreciation + one-off costs.
For larger businesses with professional management, the relevant figure is EBITDA (Earnings Before Interest, Tax, Depreciation, Amortisation) — typically the trailing 12 months or the most recent full year.
The valuation: Multiple × SDE (or EBITDA).
Discounted cash flow (DCF)
Forecast cash flows for 5-10 years, discount back to present value using a cost of capital. More common for high-growth businesses where past performance doesn''t reflect future potential. Used by private equity but not typical for SME trade sales.
Asset-based
For property-heavy or stock-heavy businesses. Less relevant for service businesses.
Typical UK SME multiples by sector
Ranges, depending on size and quality:
| Sector | SDE multiple | EBITDA multiple |
|---|---|---|
| E-commerce | 2-4× | 3-5× |
| SaaS (sub-£1m ARR) | n/a | 3-5× ARR (revenue multiple) |
| SaaS (£1-10m ARR) | n/a | 5-10× ARR |
| Professional services (accountancy, law, recruitment) | 1.5-3× | 4-7× |
| Manufacturing | 2-4× | 4-6× |
| Construction | 2-3× | 3-5× |
| Distribution / wholesale | 2-3× | 4-6× |
| Health / care | 2-4× | 5-8× |
| Specialist trades | 1.5-3× | 3-5× |
For very small businesses (SDE under £100k), the multiple is at the bottom of the range. The smaller the business, the more dependent on the owner, the lower the multiple.
For high-quality, scaled businesses (SDE over £500k, EBITDA over £1m), the multiple is at the top of the range. Some categories — particularly SaaS and specialist healthcare — can command multiples well above the range when growth, retention, and quality are excellent.
What moves the multiple
Up (gets a higher multiple)
- Owner-independence: the business operates without you for weeks at a time. Buyers pay a premium because they don''t need to replace you.
- Recurring revenue: subscription / retainer / long-term contract revenue is worth more than project work.
- Customer diversification: top customer under 20% of revenue.
- Growing top line: 20%+ year-over-year growth is a strong signal.
- High gross margins: indicates pricing power.
- Net Revenue Retention >100% (for SaaS / recurring revenue): existing customers spending more this year than last.
- Clear market position: specialist, defensible niche.
- Documented operations: SOPs, KPI dashboards, professional management.
- Long contracted backlog: confirmed future revenue.
- No litigation or regulatory issues: clean compliance history.
Down (gets a lower multiple)
- Owner-dependent: business stops without you.
- Customer concentration: top customer is 30%+ of revenue.
- Declining revenue or margin: even slight declines spook buyers.
- Project / one-off revenue: harder to forecast.
- Litigation, regulatory issues, or tax history concerns.
- No management team: only you make decisions.
- Lifestyle business: hours, location, customers — built around the owner''s preferences rather than commercial logic.
- Poor or inconsistent accounts.
- Tightly-held supplier or customer relationships: if a key relationship is personal to you, the buyer is at risk.
The gap between asking and achievable
Owner-managers consistently overestimate the value of their businesses. Reasons:
- Selection bias — they hear about top-end multiples ("such-and-such sold for 8× EBITDA!") and assume those are typical.
- Sweat equity — they value the years of work, not the financial output.
- Lifestyle-business framing — what the business gives the owner (job, status, flexibility) is bundled into the perceived value.
The achievable price for an average UK SME is typically 60-80% of the founder''s initial expectation. Plan around the realistic number, not the dream.
Buyer types and how they value differently
Strategic / trade buyers
A competitor or related business that can extract synergies (cost savings, cross-sell, market access). These buyers often pay the highest multiples — they''re buying value AND synergies. Best fit for established businesses with clear strategic positioning.
Private equity (PE)
Financial buyers acquiring for resale in 3-7 years. Pay strong multiples on quality EBITDA for the right targets, but with strict criteria (typically £1m+ EBITDA, growing, professional management). Less appetite for sub-£500k EBITDA businesses or owner-dependent ones.
Management buyouts (MBO)
The existing team buying out the founder, typically funded by debt and/or PE. Multiples often slightly lower than trade — the buyers can''t bid as aggressively because they need to service the debt from the business''s own cash flow. EOTs (Employee Ownership Trusts) are similar.
Individuals / search funds
Single buyers looking to acquire and run a business. Common at the £100k-£1m EBITDA range. Pay lower multiples because of higher perceived risk and limited capital, but the deal closes faster and the seller often gets cleaner deal terms.
The valuation negotiation
In a real transaction, valuation is the headline — but deal structure matters as much:
- Cash at completion vs deferred: lower deferred payment but more at close beats higher headline with long earn-out.
- Earn-out targets: if the seller stays involved, ensure they have control over the targets.
- Working capital adjustment: the agreed level of working capital handed over (cash, debtors, creditors, stock). Common source of post-close disputes.
- Warranties and indemnities: the seller''s liability if the business turns out not to be as described. Cap and basket levels matter.
A clean offer at a fair multiple often beats a higher offer with brutal terms.
What to do before getting a valuation
- Get 12-24 months of clean monthly management accounts.
- Calculate SDE / EBITDA properly — strip out one-offs, owner-discretionary, related-party transactions.
- Address customer concentration if you can.
- Build operational independence so the buyer isn''t buying just you.
- Speak to an exit-experienced corporate finance adviser — they''ll give a realistic range based on actual market data, not online calculators.
