Selling & Exit
Partial Sale Options for UK SME Owners
You do not have to sell 100% to take a serious slice of equity off the table. Here are the structures that work.
Not every owner wants a full exit. Many want to crystallise some value, reduce personal financial risk, and stay involved for the next chapter of growth. Partial sales, minority recapitalisations, and management buy-ins all achieve that, each with different tax, control, and lifestyle outcomes. This guide explains how each structure works, what a minority stake is actually worth, and how to choose between them.
The three structures that suit most owners
UK partial sales take three forms: a 25 to 49 percent minority to a strategic trade partner, a private equity growth investment, or a structured shareholder exit alongside continuing operators. Common in sectors where access to a larger customer base or technical platform unlocks growth.
Second, a minority recapitalisation by a financial sponsor: a private-equity firm takes a minority stake to fund a dividend recap or growth capital. Owner retains control, takes cash off the table, and accepts professional governance.
Third, a management buy-in by a partner or executive funded by external debt: brings new operational leadership and lets the founder reduce equity and workload gradually. Often the right fit when the founder is energised but wants to share the load.
How a minority stake is valued
Start with whole-equity value built on the normal adjusted-EBITDA multiple. Then apply a minority discount, typically 15 to 30%, reflecting lack of control. For unquoted shares, add a marketability discount of 5 to 15% reflecting that the buyer cannot readily sell. The discount must be evidenced from comparable transactions, not assumed.
Where the minority holder gets protective rights (board seat, veto on major decisions, anti-dilution), the discount narrows. Where they accept pure passive minority status, the discount widens. Negotiation on these rights moves the price as much as negotiation on the multiple itself.
Tax considerations for the seller
A partial sale of qualifying shares is generally a capital event eligible for CGT. Business Asset Disposal Relief may apply to the first £1m of lifetime gains at 10% CGT, with the balance at the prevailing rate. A dividend recap structure may treat distributions as income, taxed at higher rates. The right structure can save material tax; the wrong one creates an unnecessary bill.
We always work alongside the seller's tax adviser to model the after-tax outcome of each option. A higher headline number on a less efficient structure can leave less in the seller's hand than a lower headline number on a clean capital deal.
Governance and life after the partial sale
Before signing, agree the post-deal operating model: board composition, reserved matters, reporting cadence, capex sign-off thresholds, and the path to a future full exit. A clean shareholders' agreement avoids 80% of subsequent disputes.
Founders often under-estimate the lifestyle shift. Professional minority shareholders expect monthly board packs, quarterly board meetings, and visibility on hiring above a threshold. That discipline is usually good for the business and uncomfortable for the founder. We help set expectations realistically before signing.
How a partial sale interacts with a future full exit
Most minority deals come with a planned full exit in 3 to 7 years. The shareholders' agreement should define how that exit is triggered (drag-along rights, put and call options) and how the price is set. Resolving these mechanics upfront avoids the most common dispute on the second deal.
A good partial deal often increases the value of the eventual full exit because the new partner brings capability, scale, or credibility. We have seen partial sales at year zero followed by full sales at year five that delivered 2 to 3 times the multiple on the remaining stake.
When a partial sale is the wrong answer
If the founder wants to fully retire within two years, a partial sale rarely helps; it just delays the inevitable and adds complexity. If governance discipline is unwelcome, a financial partner is the wrong choice. If the business is in a tight competitive window, a minority sale that distracts management from delivery can destroy more value than it crystallises. We are honest about these cases.
Key takeaways
- You can crystallise serious value without selling 100%.
- Minority discounts apply; pro-rata is not the right starting point.
- Tax structure matters as much as headline price.
- Plan the governance and the second-deal mechanics upfront.
Frequently asked questions
What percentage stake can I sell and keep control?
Anything below 50% leaves day-to-day control with you, subject to reserved matters in the shareholders' agreement. Many deals settle at 25 to 35% to preserve clear founder control while crystallising meaningful value.
Is a minority stake worth pro-rata of the whole-business value?
Generally no. Apply a minority discount of 15 to 30% and a marketability discount of 5 to 15%. A 30% stake in a £10m business is typically worth £1.8m to £2.4m, not £3m.
Will a PE minority investor take a board seat?
Almost always. Expect one or two non-executive directors, monthly board packs, quarterly board meetings, and reserved matters covering hiring above a threshold, capex, and material contracts.
Can I avoid CGT on a partial sale?
Not avoid, but optimise. Business Asset Disposal Relief, share-for-share rollovers, and well-timed Enterprise Investment Scheme reinvestments can all reduce the effective rate. We model the options with the tax adviser before signing.
How long does a partial sale take to complete?
Typically 4 to 6 months from formal process start, faster than a full trade sale because the buyer pool is more targeted and due diligence is lighter on integration risk.
Will a partial sale make the future full exit easier?
Usually yes, particularly with a financial sponsor experienced in driving subsequent exits. The discipline, governance, and scale they bring often lifts the eventual full-exit multiple meaningfully.
