An exit is the point at which everything the business has documented — or failed to document — is examined by someone with a financial interest in finding problems. Issues that seemed immaterial while trading become price adjustments, indemnities or deferred consideration.
Sellers who prepare early tend to achieve cleaner deals: fewer warranty qualifications, less money held in escrow, shorter timetables and fewer renegotiations. The work is mostly unglamorous corporate housekeeping.
This guide sets out the exit routes available to a UK private company, the pre-sale preparation that pays, and what to expect in the transaction itself.
Exit routes and what each demands
The common routes are a trade sale to a strategic buyer, a private equity transaction, a management buy-out, an employee ownership trust, or a share buyback funded by the company. Each has different tax, funding and documentation profiles.
Trade sales usually deliver the highest headline value but involve extensive diligence and full warranty packages. Management buy-outs are quicker and friendlier but constrained by funding. Employee ownership trusts offer a tax-advantaged route where the founder wants continuity, subject to strict qualifying conditions.
Pre-sale housekeeping
Start eighteen to twenty-four months out. Bring statutory registers up to date, confirm clean title to every share, resolve any historic allotment or transfer irregularities, and regularise option grants. Ensure IP is owned by the company with a complete chain of assignments from every employee, contractor and agency.
Then review contracts for change-of-control and assignment restrictions, resolve outstanding disputes, settle any employment status questions, complete data protection documentation, check property title and lease obligations, and align management accounts with statutory accounts. Each unresolved item becomes a diligence finding with a price attached.
Structuring the deal: shares or assets
Buyers of a private company usually acquire the shares, taking the company with all its history and liabilities, which is why they demand warranties and indemnities. Asset purchases allow a buyer to cherry-pick, leaving liabilities behind, but require consents to transfer contracts and trigger TUPE for employees.
Sellers generally prefer share sales for a clean break and for tax reasons; buyers often prefer assets. The structure is negotiated with tax advice on both sides, and the answer shapes the entire documentation set.
Warranties, indemnities and disclosure
A share purchase agreement contains warranties — contractual statements about the business — and indemnities for identified risks. Liability is typically capped by amount and time, with lower caps and shorter periods for commercial warranties and higher, longer limits for title, capacity and tax.
The disclosure letter qualifies the warranties. A thorough disclosure exercise is the seller's principal protection: a matter properly disclosed generally cannot found a warranty claim. Warranty and indemnity insurance is increasingly used to bridge the gap between what buyers want and what sellers will give, particularly where sellers are exiting entirely.
Consideration: cash, earn-outs and escrow
Consideration may be cash on completion, deferred payments, an earn-out linked to post-completion performance, shares or loan notes in the buyer, or a combination. Earn-outs bridge valuation gaps but create risk: your payment depends on a business run by someone else.
If you agree an earn-out, negotiate protective covenants over how the business will be operated during the period, define the metrics precisely with worked examples, and specify the dispute mechanism — expert determination is usually preferable to litigation. Escrow or retention accounts covering warranty claims should have a defined release date and release mechanics.
Tax, timing and personal planning
Business Asset Disposal Relief may reduce the capital gains tax rate on qualifying disposals up to a lifetime limit, subject to conditions on shareholding percentage, officer or employee status and the holding period. Because conditions must be met for a defined period before disposal, this planning must happen well in advance.
Also consider restrictive covenants you will be asked to give, any continuing role and its terms, treatment of option holders, and what the shareholders' agreement or articles require in terms of drag, tag and pre-emption. Take tax advice early — the structure that maximises headline price is not always the one that maximises net proceeds.
Key points
- Begin exit preparation 18–24 months before you expect to go to market.
- Clean statutory registers and a complete IP chain of title remove diligence friction.
- Share sales transfer liabilities; asset sales require consents and trigger TUPE.
- Thorough disclosure is the seller's main protection against warranty claims.
- Earn-outs need precise metrics, operating covenants and an expert dispute route.
- Business Asset Disposal Relief conditions must be satisfied well before disposal.
Frequently asked questions
- How long does a company sale take?
- From heads of terms to completion, three to six months is typical for an owner-managed company, longer where regulatory consents, multiple jurisdictions or complex diligence findings are involved.
- What is a locked-box mechanism?
- A pricing structure where the price is fixed by reference to a historic balance sheet date, with the seller giving covenants against value leakage between that date and completion. It avoids post-completion accounts disputes.
- Will I have to stay on after the sale?
- Often, particularly where the buyer values founder relationships or where an earn-out applies. Terms of any continuing role should be negotiated as part of the deal, not left to a post-completion conversation.
- What is W&I insurance?
- Warranty and indemnity insurance covers loss arising from a breach of warranty, allowing sellers to limit their liability to a nominal amount while buyers retain recourse. It is now common on mid-market deals and can accelerate negotiations.
