What Do Private Equity Firms Look for When Buying a UK Business?

Private equity is not the right buyer for every business — and PE firms are not looking for perfection. What they are looking for is a specific set of characteristics that make a business financeable, scalable, and capable of delivering a return within three to five years. If your business clears those hurdles, PE becomes a genuinely compelling exit route. If it doesn't, it's worth knowing that early rather than wasting twelve months of preparation.

What is the EBITDA threshold for PE investment in the UK?

For most UK buyout funds operating in the lower mid-market, the minimum they want to see is around £1.5m EBITDA. Below that, the deal economics rarely work — the transaction costs, management time, and leverage constraints simply don't justify the ticket size for a fund that needs to deploy meaningful capital.

Growth equity investors and some smaller specialist funds will go lower, sometimes to £800k–£1m EBITDA, particularly in high-growth or recurring revenue businesses where the growth trajectory is the story. But these are the exception, not the rule.

The more relevant number for most owner-managers is £2m–£5m EBITDA, which is where the bulk of UK lower mid-market PE activity sits. At this level, you have genuine competition between funds, which creates negotiating leverage on deal structure and valuation.

EBITDA RangeTypical Buyer TypeTypical EV/EBITDA Multiple (UK, 2025–26)
£800k – £1.5mGrowth equity, smaller funds, trade buyers4x – 6x
£1.5m – £3mLower mid-market PE, family offices5x – 8x
£3m – £7mMid-market PE, divisional trade buyers6x – 10x
£7m+Established mid-market and upper mid-market PE8x – 12x+

These are realistic ranges across relevant sectors. Businesses with high recurring revenue or strong IP will sit at the top end; cyclical or asset-heavy businesses towards the bottom.

Why does the management team matter so much to PE?

This is arguably the most important criterion of all, and it catches out more owner-managers than anything else. A PE firm is not buying your job. They are buying a business they can run, grow, and exit — and they need a management team in place to do that.

If you, as the founder or owner-manager, are the business — the key customer relationships, the technical expertise, the supplier negotiations, the delivery capability — then PE will struggle to price that risk. You may well be asked to stay on for a period post-completion, but funds are deeply uncomfortable with key-person dependency.

What PE wants to see is a credible, capable management team who can run the business without you in the room. That means a finance director who produces reliable, timely management accounts. It means sales leadership that owns the pipeline. It means operations management that doesn't escalate every problem to the top.

This doesn't need to be a large team. In a business turning over £8m–£12m, three or four strong people around the management table can be enough — provided each one has clear accountability and a track record.

What sectors do PE firms favour — and which do they avoid?

PE firms in the UK mid-market broadly favour businesses with recurring or repeat revenue, defensible market positions, and scalable economics. Sectors that consistently attract PE interest include:

  • Healthcare services and pharmaceutical services
  • Professional services with retainer or contract income
  • Business services with multi-year client relationships
  • Facilities management with long-term contracts
  • Logistics and supply chain with embedded client dependencies
  • Recruitment (contingency less so; retained and RPO models more so)
  • Food production and specialist manufacturing with defensible niche positions

What PE tends to avoid — or discount heavily — includes:

  • Highly cyclical businesses where revenue is tied to construction cycles or commodity pricing
  • Commoditised businesses competing primarily on price
  • Businesses with high regulatory capital requirements that restrict financial engineering
  • Customer-concentrated businesses (one client representing more than 25–30% of revenue is a red flag)
  • Owner-managed businesses with no second tier of management (see above)

The question PE is always asking is: can we put leverage on this business and still sleep at night? A business with lumpy, unpredictable revenue and thin margins does not lend itself to that.

What is the difference between a platform and an add-on acquisition?

Understanding this distinction is important if you're trying to assess how PE will view your business.

A platform is the founding acquisition around which a PE firm builds a buy-and-build strategy. The platform needs to have the infrastructure, management, and market position to absorb smaller acquisitions over time. Platform businesses typically need to clear higher EBITDA thresholds and demonstrate genuine scalability.

An add-on is a smaller business acquired to bolt onto an existing platform — to extend its geography, add a capability, or consolidate a fragmented market. Add-ons can be significantly smaller, sometimes below £1m EBITDA, and the strategic logic is about fit with the platform rather than standalone investment merit.

If your business is likely to be attractive as an add-on to an existing PE-backed platform in your sector, you may find that the platform's sponsor — the PE fund behind it — is a credible acquirer even if your EBITDA wouldn't normally meet that fund's standalone investment threshold.

What does a good EBITDA bridge look like?

When PE looks at your business, they will scrutinise the EBITDA figure carefully — not simply take the number in your accounts at face value. They will typically build an EBITDA bridge: a reconciliation that moves from reported EBITDA to a "normalised" or "adjusted" EBITDA that reflects the true underlying earnings power of the business.

Common adjustments include:

  • Removing your owner's salary above market rate (or below market rate — both get adjusted)
  • Adding back one-off costs: restructuring, legal disputes, one-time capex expensed through the P&L
  • Removing personal expenses run through the business
  • Adjusting for rent where the property is owned separately by you personally
  • Reflecting the run-rate impact of contracts won but not yet fully in the numbers

The discipline here is this: every adjustment you put in the bridge will be challenged. PE firms and their advisers are experienced at forensic financial diligence. The adjustments need to be defensible, documented, and not overly heroic. A bridge that adds 40% back to reported EBITDA will raise eyebrows and increase deal risk.

Why does PE care so much about working capital?

Working capital — the difference between current assets and current liabilities — is the mechanism through which cash is consumed or released as a business grows. PE firms care about it for two reasons.

First, deal mechanics: in most UK transactions, the target working capital level is agreed as part of the sale and purchase agreement (SPA). The completion accounts will compare actual working capital at completion against that target, with adjustments to the price if there's a shortfall. A business that manages debtors and creditors poorly will find this a painful process.

Second, post-completion growth: PE typically plans to grow the business after acquisition. If working capital is poorly managed, growth consumes cash and strains the leverage the fund has put on the business. A business that converts EBITDA to cash efficiently — short debtor days, good stock turns, well-managed creditors — is simply more fundable.

Get your debtor days under control before you approach PE. It is one of the most practical things you can do to strengthen your position.

Is my business PE-ready? A self-assessment checklist

Work through these honestly before committing to a PE process:

  1. EBITDA threshold — Is your normalised EBITDA above £1.5m? Ideally above £2m?
  2. Management team — Can the business operate and grow without you in day-to-day control?
  3. Revenue quality — Do you have recurring, contracted, or repeat revenue rather than purely transactional income?
  4. Customer concentration — Does any single customer account for more than 25% of revenue?
  5. Financial reporting — Do you produce timely, accurate monthly management accounts?
  6. EBITDA bridge — Can you defend a clean normalised EBITDA figure with documented adjustments?
  7. Working capital — Are debtor days and creditor terms under control and consistent?
  8. Growth story — Is there a credible, evidence-backed plan for growth post-investment?
  9. Sector positioning — Is your business in a sector PE currently favours, with a defensible market position?
  10. Clean legal structure — Are there any legacy legal, property, or HR issues that would complicate diligence?

If you can answer positively to eight or more of these, a PE process is worth exploring seriously. If you're struggling with three or four, it may be worth addressing those before going to market.

If you're exploring PE as a route to exit, it's worth understanding how the overall process works and how buyers beyond PE assess business value. Private Equity as an Exit Route for UK Business Owners covers the full process from first approach to completion. What Buyers Look for When Valuing Your Business broadens the picture to include trade buyers and other acquirers who may also be relevant to your situation.

FAQ

Do PE firms in the UK always require the owner to stay on after the sale? Not always, but often for a period. If you are the primary driver of revenue or relationships, expect pressure to remain for a transition period of twelve to twenty-four months. If there is a strong management team in place, a clean exit at completion is more achievable.

What multiple will a PE firm pay for my business? It depends on sector, EBITDA size, revenue quality, and growth profile. Realistic UK ranges sit between 5x and 9x EBITDA for most lower mid-market transactions. Businesses with high recurring revenue or strong market positions attract premiums. See the table earlier in this article for sector-level guidance.

Is PE better than selling to a trade buyer? It depends on your priorities. PE typically offers partial liquidity — you often retain a stake and participate in a second exit. Trade buyers usually offer a clean break. PE can offer higher headline multiples in the right conditions; trade buyers may offer strategic premium. There is no universal answer.

What is the typical timeline for a UK PE deal? From first approach to completion, expect six to nine months for a well-run process. Poorly prepared businesses, or those with messy diligence, can stretch well beyond twelve months. Heads of terms (HoTs) typically agreed within three to four months; completion accounts and SPA negotiation taking the remainder.

What is a management buyout and how does it relate to PE? A management buyout (MBO) is where the existing management team buys the business, typically using PE funding alongside their own equity contribution. For owner-managers with a strong team in place, an MBO can be an attractive route — it keeps continuity and may be less disruptive than a trade sale.

Will PE firms consider businesses outside London and the South East? Yes. UK mid-market PE is active across all regions. Sector and financial profile matter far more than geography. Businesses in the Midlands, North West, Yorkshire, and Scotland are regularly backed by UK and international funds.
