Private Equity as an Exit Route: What UK Mid-Market Owners Need to Know

Private equity is not the right exit route for most UK mid-market business owners. But when it fits, it can be exceptionally lucrative. PE buyers typically pay higher multiples than trade buyers in certain sectors, they move at speed when they want a business, and a partial exit with rollover equity can deliver a second, often larger, payout further down the line. The critical question is whether your business is genuinely PE-investable, and that answer is more specific than most owners realise.

What are PE firms actually looking for?

PE firms are financial investors. They are not buying a business because they love your industry. They are buying it because they believe they can grow it, professionalise it, and sell it for significantly more than they paid, typically within three to five years.

That means they are looking for a specific set of conditions: recurring or contracted revenue, demonstrable EBITDA growth, a management team capable of running the business without the founding owner, and a credible story about how the business gets bigger. Sector matters too. PE firms are active right now across healthcare services, facilities management, professional services, construction services, logistics, recruitment, and food manufacturing. All areas where fragmented markets allow a buy-and-build strategy.

The EBITDA threshold is real and it matters. Most UK buyout funds will not seriously consider a business with EBITDA below £1.5m, and many mid-market funds are targeting £3m and above. Growth equity investors can sometimes go lower, but they expect faster growth in return.

Platform vs add-on: why the distinction matters

When PE firms talk about "platform" businesses, they mean a company large enough and operationally strong enough to serve as the foundation for acquisitions. An add-on is a smaller business they bolt onto an existing platform they already own.

This distinction affects valuation significantly. Platform businesses typically attract premium multiples. A PE firm building a buy-and-build strategy will pay more for the right platform because it accelerates their entire thesis. Add-on acquisitions often receive lower multiples, sometimes at a discount to market, because the strategic value flows to the platform rather than the target.

EBITDA multiple ranges by sector (UK mid-market, 2025–2026):

SectorTypical PE Multiple (EBITDA)Notes
Healthcare services8–14xHigh demand, recurring revenue
Facilities management5–8xContract quality and retention critical
Professional services6–10xFee concentration and key-person risk scrutinised
Recruitment (permanent)4–7xCyclicality viewed cautiously
Logistics / distribution5–8xAsset intensity affects leverage capacity
Food manufacturing5–9xCustomer concentration and margin stability key
Construction services4–7xOrder book visibility and bonding capacity assessed
Business services6–10xRecurring contracts attract premium

These ranges reflect platform acquisitions. Add-on multiples can be two to four turns lower.

How does a typical PE deal structure work?

Most PE acquisitions in the UK mid-market are leveraged buyouts (LBOs). The PE firm uses a combination of equity from their fund and debt. Typically senior bank debt. To fund the purchase. The debt sits on the acquired business's balance sheet, not the PE firm's. The business services this debt from its own cash flows.

This has two implications for you as a seller. First, the PE firm's ability to pay a high multiple is partly dependent on how much debt the business can service. Which is a function of your EBITDA, your cash conversion, and your capital expenditure requirements. A capital-intensive business with lumpy cash flows is harder to leverage, which constrains what a PE firm can offer. Second, because the deal involves leverage, due diligence is thorough and lenders have their own requirements. Expect the process to be longer and more demanding than a straightforward trade sale.

Typical UK deal timeline for a PE-backed buyout:

  1. Initial approach and NDA. 2–4 weeks
  2. Management presentation and information pack. 4–6 weeks
  3. Indicative offer / HoTs agreed. 2–4 weeks
  4. Full due diligence (financial, commercial, legal, tax). 8–14 weeks
  5. Debt funding arranged. Runs concurrently with due diligence
  6. SPA negotiation and completion. 4–8 weeks

Total: typically six to twelve months from first conversation to completion.

What does a PE exit actually mean for you as the seller?

This is where many owners get a surprise. A PE deal is rarely a clean exit.

Most PE firms expect the founding owner or senior management to retain a meaningful equity stake. Typically 20–40%. In the business post-completion. This is called a rollover. You are selling the majority of your equity for cash now, and reinvesting a portion into the new leveraged vehicle alongside the PE fund. The idea is alignment: PE firms want management to be motivated to grow the business through the hold period.

An earn-out is also common, particularly where a significant portion of the business's value is tied to relationships or contracts you personally hold. The earn-out is contingent on financial performance over one to three years post-completion and is not guaranteed.

You should also expect to remain involved in the business, typically at executive level, for at least the initial years of the PE hold. If your intention is to hand over the keys and walk away immediately, PE is unlikely to be the right route. A trade sale, an EOT, or a carefully structured MBO would be more suitable.

The upside of rollover equity is real and should not be dismissed. If the PE firm executes their strategy successfully and exits at a higher multiple. Which is the entire point of their model. Your rolled equity can be worth considerably more than the initial cash you took off the table.

Which types of PE firm are active in the UK mid-market?

Not all PE firms are the same. Understanding the landscape helps you identify who you should actually be talking to.

Growth equity funds back businesses that do not need a change of control. They take a minority stake. Often 20–40%. And provide capital and strategic support. The owner retains control. These funds are relevant if you want external capital and a partial exit without selling majority control.

Buyout funds acquire majority or full control. This is the classic leveraged buyout model. In the UK mid-market, firms active in the £10m–£100m enterprise value range include a significant number of sector-specialist funds alongside the generalist names.

Sector-specialist funds focus exclusively on one or two industries. In healthcare services, facilities management, professional services, and technology-enabled business services, there are dedicated PE funds whose entire portfolio sits within your sector. They often understand your business faster, pay more accurately, and add more relevant operational support than a generalist.

What makes a business PE-investable vs what doesn't?

Be honest with yourself here. The following characteristics attract PE interest:

  • EBITDA of £1.5m minimum, ideally £3m+
  • Revenue visibility through contracts, retainers, or repeat business
  • Management team that can operate without the founding owner
  • A fragmented market where acquisitions are a credible growth route
  • Clean financials with minimal owner personal expenses run through the business
  • No significant customer concentration (typically no single customer above 20–25% of revenue)

The following characteristics make PE investment difficult or impossible:

  • Owner-dependent businesses where relationships, contracts, or key skills sit entirely with the founder
  • Poor financial records or heavily normalised accounts
  • Businesses where EBITDA has declined or is inconsistent year-on-year
  • Markets with limited consolidation potential or structural decline
  • Significant off-balance-sheet liabilities, pension deficits, or environmental obligations
  • Revenue entirely reliant on one or two large contracts with no renewal certainty

How do you get on a PE firm's radar?

PE firms are not passive. The good ones run proprietary deal origination. They will identify businesses they want to back and approach them directly. If you are in a sector they are actively building in, you may already be on their list.

That said, most mid-market PE processes run through corporate finance advisers who know which funds are looking for what. Running a structured process. Even an informal market-testing exercise. Is the most reliable way to generate competitive tension and identify the right counterparty.

You can also get on the radar by:

  1. Being visible at sector-specific conferences and events
  2. Publishing thought leadership or appearing in trade press
  3. Working with an adviser who has established relationships with active mid-market PE funds
  4. Engaging with the PE funds' operating partners and sector leads directly via LinkedIn, where many are genuinely accessible

FAQ

What EBITDA do I need to attract PE interest in the UK? Most buyout funds start at £1.5m EBITDA, with serious interest from larger mid-market funds beginning around £3m. Growth equity investors can go lower but expect faster growth.

Will I have to stay in the business if I sell to PE? Almost certainly for the first one to three years. PE firms expect management continuity and will typically require you to roll equity into the new structure. A completely clean exit at completion is unusual in a PE deal.

Are PE buyers likely to pay more than trade buyers? In some sectors, yes. Particularly where PE firms are running a buy-and-build strategy and your business is the right platform. In others, a trade buyer with genuine synergies will pay more. This is why running a competitive process with multiple buyer types is important.

What is rollover equity and do I have to accept it? Rollover means reinvesting a portion of your sale proceeds into the new leveraged structure rather than taking all cash at completion. PE firms typically expect 20–40% rollover. It is negotiable in principle, but a PE firm asking for zero rollover is a red flag. It suggests they do not believe management adds value post-deal.

How long does a PE-backed deal take to complete in the UK? Six to twelve months is realistic. The debt funding process adds complexity that a straightforward trade sale does not have. Thorough financial, commercial, and legal due diligence is standard.

What happens at the end of the PE hold period? PE funds typically hold for three to five years, then exit. Either through a sale to another PE firm (secondary buyout), a trade sale, or occasionally a stock market flotation. If you have retained rollover equity, this is when your second liquidity event occurs.
