How Private Equity Deals Work: A Plain-English Guide for UK Founders
Selling to private equity isn’t “all cash out the door.” It’s a structure — some cash now, some equity rolled into the next chapter, and a potential second bite that can be worth more than the first. Here’s exactly how a PE buyout works from the founder’s seat, how it unlocks your capital, and what PE firms look for before they’ll pay up.
How a private equity buyout actually works
A private equity firm raises a fund from institutional investors, then buys established, profitable companies, grows them over a few years, and sells them for more. When they buy your business, you’re not dealing with a strategic competitor — you’re dealing with a financial buyer whose entire model depends on you and your team continuing to succeed after the deal.
Here’s the lifecycle of a typical deal, in seven steps:
- Origination. A firm approaches you (or you’re introduced) as a potential fit for their strategy.
- Indicative offer. After early information, they issue a non-binding offer (an IOI or LOI) with a headline valuation.
- Management meetings. They get to know you and the team, and test the growth story.
- Due diligence. Financial, commercial, legal and tax teams stress-test the business.
- SPA & completion. You sign the share purchase agreement, funds move, and the deal closes.
- The hold. Over 3–7 years the firm grows EBITDA — through operational improvements, buy-and-build acquisitions and market expansion.
- The second exit. They sell the (now larger) business — and your rolled equity pays out again.
The mechanic underneath is the leveraged buyout (LBO). The firm funds the purchase price from three pots: debt secured against your company, equity from their fund, and often equity you roll over. Debt amplifies their return — but it also means the business carries borrowings after completion, which is one reason PE firms are so focused on stable, cash-generative companies.
Most PE deals are majority stakes — the firm typically takes 60–90% and leaves you a meaningful minority — though minority-only deals exist too. So no, you usually don’t have to sell 100%. Keeping you invested is a feature, not a compromise: it’s how PE aligns you with the growth plan.
How a PE deal unlocks capital for the owner
Your payout from a PE deal usually splits into three buckets:
Equity rollover is the piece founders most often misunderstand. Instead of taking all cash, you reinvest part of your proceeds into the new entity the PE firm creates. You keep skin in the game — and when the firm sells the business again, your rolled stake pays out a second time. In the UK this is the second bite of the cherry; in the US, the second bite of the apple.
UK founders commonly roll 10–30% and take the rest as cash at close. The trade-off is simple to state and hard to decide: cash at close is certain and liquid; rolled equity is bigger but riskier and illiquid until the next exit. If the firm doubles or triples the business, your second bite can exceed your entire first-bite cash. If the plan stalls, rolled equity can underperform — or in a poor deal, be worth little.
A business services company with £2m EBITDA is valued at 8× = £16m. The founder owns 100% and rolls 25%:
- Cash at close (75%)£12.0m
- Rolled equity (25%)£4.0m
- Second bite at ~2.5× over 4 yrs£10.0m
- Total potential proceeds£22.0m
vs £16m taking all cash today. Illustrative only — the second bite is at risk, not guaranteed.
There’s a UK tax angle worth knowing (and confirming with a specialist): the rolled portion can often be structured as a share-for-share exchange, deferring capital gains tax on that slice until the second exit, while your cash at close is taxable now — potentially with Business Asset Disposal Relief (BADR). Rates are moving: BADR is 18% from April 2026 on the first £1m of qualifying gains, and standard CGT on share sales is 24%. This is general information, not tax advice.
What private equity firms look for in a business
PE firms are picky because their return maths depends on it. Each criterion below de-risks the debt they put on the business and supports the multiple expansion they need to profit. Broadly, they want:
PE will also expect something of you: typically staying on through a transition, hitting agreed growth targets, and sometimes an earn-out tying part of your consideration to future performance. Earn-outs can bridge a valuation gap, but they put money at risk against results you may no longer fully control — negotiate the targets and definitions carefully.
What multiple of EBITDA does private equity pay in the UK?
As a rule of thumb, UK mid-market PE deals price at roughly 5–10× EBITDA. BDO’s Private Company Price Index has shown a long-run PE average nearer 12×, though that skews toward larger, higher-quality businesses. Where you land in the range is driven by:
- Size — bigger EBITDA usually earns a bigger multiple.
- Growth — faster, durable growth is the single biggest lever.
- Margins & recurring revenue — quality of earnings, not just quantity.
- Sector — software, healthcare and business services command premiums over asset-heavy or cyclical sectors.
- Management depth — a business that doesn’t depend on the founder is worth more.
How long do PE firms hold a company, and how do they make money?
Most UK PE firms hold a business for 3–7 years. The clock is set by the fund’s lifecycle: investors expect their capital back within a defined window, so the firm needs to buy, grow and sell inside it. They make money by buying partly with debt, growing EBITDA, often expanding the valuation multiple through buy-and-build, and then selling at a higher enterprise value.
That second sale can be a trade sale (to a strategic buyer), a secondary buyout (to another PE firm), or occasionally an IPO. Whichever route, it’s the moment your rolled equity crystallises — the same growth that powers the firm’s return powers your second bite.
Should you sell your business to private equity?
- Take real cash off the table now while keeping upside
- Growth capital and operational expertise to scale faster
- A structured path to a bigger second exit
- You give up full control of the business
- Debt and performance pressure post-deal
- Rolled equity is illiquid and at risk
PE isn’t always the right answer — a clean trade sale or a full cash exit can beat it if you want out entirely. The way to decide isn’t a listicle; it’s your own numbers. Model your cash at close against a realistic second bite before you sit down with advisers, so you walk in knowing what “good” looks like.

Frequently asked questions
How does private equity pay for a company?
In a private equity buyout the price is usually funded three ways: debt secured against your company (the leveraged buyout, or LBO), equity from the PE fund, and often equity you roll over yourself. As the seller you typically receive most of your proceeds as cash at completion, with the balance reinvested as rolled equity in the new PE-backed company.
Do I have to sell 100% of my business to private equity?
No. Most PE deals are majority stakes (often 60–90%), leaving you with a meaningful minority holding, and minority-only deals also exist. Selling less than 100% is central to the PE model because it keeps you invested and incentivised to grow the business toward a second exit.
What is equity rollover in a private equity deal?
Equity rollover means reinvesting part of your sale proceeds into the new PE-backed entity instead of taking all cash at close. You keep skin in the game, and your rolled stake can grow with the business and pay out again when the PE firm sells — the second bite of the apple.
How much equity should I roll over?
UK founders commonly roll 10–30% of their proceeds, taking the rest as cash at close, though PE firms sometimes ask for more. The right amount balances how much cash certainty you want now against how much upside you want in the next exit — and your confidence in the buyer’s growth plan.
What is the second bite of the apple in a private equity deal?
The second bite of the apple (in the UK, the second bite of the cherry) is the payout you receive on your rolled equity when the PE firm sells the business again, typically in 3–7 years. If the company has grown, that second bite can exceed your original cash at close — but it is at risk and illiquid until the exit.
What return should I expect on rollover equity?
Returns depend entirely on how much the PE firm grows enterprise value over the hold, which is why founders model it as best, base and worst-case scenarios. A successful hold can multiply your rolled stake, but there is no guarantee — rolled equity can also underperform or, in a poor deal, be worth little.
Is equity rollover taxed in the UK?
Often the rolled portion can be structured as a share-for-share exchange so UK capital gains tax is deferred until the second exit, while your cash at close is taxable now — potentially with Business Asset Disposal Relief. Rates are changing (BADR is 18% from April 2026 on the first £1m of qualifying gains; standard CGT on share sales is 24%), so confirm treatment with a UK tax adviser.
What multiple of EBITDA does private equity pay in the UK?
UK mid-market PE deals typically price at roughly 5–10× EBITDA, with BDO’s Private Company Price Index showing a long-run PE average nearer 12× for larger, higher-quality businesses. Your multiple rises with scale, growth, margins, recurring revenue and sector attractiveness.
What do private equity firms look for in a business?
PE firms typically want EBITDA of at least £1–3m, consistent or growing revenue, healthy defensible margins, recurring or contracted income, a management team that can run the business without the founder, and an attractive, consolidating sector. These traits de-risk the debt and support the multiple expansion PE needs to make its return.
How long do private equity firms keep companies?
Most UK PE firms hold a company for around 3–7 years. The timeline is driven by the fund’s lifecycle and the need to grow EBITDA, expand the valuation multiple and return capital to their investors within a set period before selling the business again.
How do private equity firms make money?
PE firms buy a company partly with debt, grow its EBITDA and often expand its valuation multiple through buy-and-build, then sell it at a higher enterprise value within a few years. The same growth that generates their return also drives the value of any equity you roll over.
Should I consider an earnout when selling my business?
An earn-out ties part of your consideration to hitting future targets after completion. It can bridge a valuation gap and increase your total proceeds, but it puts money at risk against performance you may no longer fully control, so the targets and definitions must be negotiated carefully.
Cash at close vs rollover equity: which is better?
Cash at close gives certainty and liquidity today; rolled equity offers larger but riskier upside at the second exit. The right split depends on your appetite for risk, need for liquidity and belief in the buyer’s growth plan — modelling both sides side by side is the best way to decide.
