How to Sell a Business in the UK: A 2026 Guide
Selling a business is rarely a single transaction — it’s usually the outcome of a strategy that started a year or more earlier. Owners who plan ahead consistently get better prices and pay less tax than those who wait until they’re ready to leave and only then start preparing.How to sell a business in the UK isn’t usually a single transaction — it’s the outcome of a strategy that started a year or more earlier. Owners who plan ahead consistently get better prices and pay less tax than those who wait until they’re ready to leave and only then start preparing.
This guide covers how to sell a business UK: the actual process from decision to completion, how valuation works, the Business Asset Disposal Relief change that took effect in April 2026, and the mistakes that quietly cost sellers money.
Key Takeaways
- Business Asset Disposal Relief (BADR) now taxes qualifying gains at 18%, up from the previous rate, following the change effective 6 April 2026.
- Standard Capital Gains Tax applies above BADR’s £1 million lifetime limit: 18% for basic rate taxpayers, 24% for higher and additional rate taxpayers, after the £3,000 annual allowance.
- Most UK SME valuations use an earnings-based (EBITDA multiple) approach — value is an informed opinion, not a guaranteed price.
- Effective exit planning typically needs a lead time of a year or more, to meet BADR’s 2-year ownership requirement and tidy up the business beforehand.
- Whether you sell assets or shares changes both your tax treatment and how much of the business’s history the buyer inherits — mirroring the same trade-off from the buyer’s side.
- The 2026 Business Relief changes to Inheritance Tax make it worth reviewing your exit and succession plans together, not separately.

The Business Sale Process, Step by Step
Selling a UK business typically follows six stages: prepare, value, find a buyer, negotiate heads of terms, complete due diligence, then sign and complete — with tax and legal advice sought early, not at the end.
- Prepare clean, normalised accounts and gather the documentation a buyer will expect to see.
- Get an independent valuation to understand a realistic price range.
- Decide your exit structure — full sale, partial sale, management buyout, or employee ownership trust.
- Find a buyer, directly or through a business broker.
- Agree heads of terms, then allow the buyer to complete due diligence.
- Negotiate the final sale agreement and complete.
How Business Valuation Actually Works
Most UK small business valuations use an earnings-based approach — typically adjusted EBITDA multiplied by an industry-standard multiple — though the right method depends on your sector, size and the purpose of the valuation. A valuation is a considered opinion of value, not a guaranteed sale price.
- “Add-backs” (one-off costs, above-market owner salary, personal expenses run through the business) are added back to profit before applying a multiple, since a buyer is paying for ongoing, maintainable earnings.
- Industry multiples vary significantly by sector — there’s no single “correct” multiple that applies across all businesses.
- A valuation for selling the whole business can differ from one done for a partial sale, a management buyout, or an Employee Ownership Trust.
Business Asset Disposal Relief: The 2026 Change
From 6 April 2026, Business Asset Disposal Relief (BADR) taxes qualifying gains from selling a business at 18%, rather than the standard Capital Gains Tax rates, up to a £1 million lifetime limit. This is the single most consequential recent change for anyone planning a sale.
- To qualify, you generally need to have owned the business for at least 2 years before the sale.
- You must be selling all or part of a genuine trading business — investment-heavy or non-trading businesses can jeopardise eligibility.
- For share sales, you typically need to be an employee or director holding at least 5% of the shares.
- Gains above the £1 million lifetime limit are taxed at standard Capital Gains Tax rates: 18% for basic rate taxpayers, 24% for higher and additional rate taxpayers (2026/27), after the £3,000 annual CGT allowance.
Selling Assets vs Selling Shares
As a seller, a share sale usually gives you the better tax outcome (BADR generally applies more cleanly to share disposals), while an asset sale can leave the company itself — and any remaining liabilities — in your hands after completion. This mirrors the buyer’s side of the same decision from the opposite angle.
| Selling Assets | Selling Shares | |
|---|---|---|
| What the buyer takes on | Only the assets agreed | The whole company, including liabilities |
| Your tax treatment | Can trigger tax at the company level, then again on extraction | Often cleaner access to BADR at 18% |
| What’s left with you | The company shell (and any unsold liabilities) remains yours | Nothing — the company itself has changed hands |
| Buyer preference | Often preferred by buyers (more control, fewer inherited risks) | Often preferred by sellers (better tax treatment) |
Common Challenges When Selling
- Leaving preparation too late to meet BADR’s 2-year ownership requirement comfortably
- A balance sheet cluttered with non-trading assets that jeopardise relief eligibility
- Revenue too dependent on the current owner, which depresses buyer confidence and valuation
- Disagreement between buyer and seller over asset vs share structure, since each favours a different party
- Underestimating how long the full process takes, from preparation to completion
Illustrative Examples
Illustrative Example — Share Sale with BADR: A director who has owned 20% of a trading company for 4 years sells their shares, qualifying for BADR and paying 18% tax on the gain up to the £1 million lifetime limit.
Illustrative Example — Asset Sale: A retiring sole trader sells the equipment, stock and customer list of their business directly, rather than incorporating and selling shares, keeping the transaction simpler at a smaller scale.
Illustrative Example — Balance Sheet Cleanup: A business owner spends 18 months before a planned sale extracting excess retained cash as dividends, specifically to protect BADR eligibility on the eventual sale.
Common Mistakes to Avoid
| Mistake | Why It Happens | Consequence | How to Avoid It |
|---|---|---|---|
| Starting preparation too late | Deciding to sell and immediately looking for a buyer | Missed BADR eligibility or a rushed, weaker sale | Start planning at least a year ahead of a target sale date |
| Ignoring the balance sheet | Not realising excess cash affects relief eligibility | Reduced or lost BADR relief | Review and tidy the balance sheet well in advance |
| Getting tax advice too late | Approaching buyers before structuring the deal properly | A worse tax outcome that’s hard to unwind | Get tax and legal advice before your first buyer conversation |
| Over-relying on one valuation method | Assuming a single multiple applies universally | Under- or over-estimating realistic sale value | Get an independent valuation appropriate to your sector and purpose |
| Treating the sale as separate from succession planning | Not connecting exit and estate planning | Missed opportunities under 2026 Business Relief rules | Review sale and succession plans together, especially near the £2.5m Business Relief threshold |
Editor’s Insights
- BADR’s 2-year ownership rule catches out founders who incorporate late — the clock generally starts from incorporation, not from when the underlying trade began.
- Buyers pay for maintainable earnings, not peak earnings — a single strong year doesn’t carry the same weight as consistent performance.
- A business broker can widen your buyer pool, but their fee (often a percentage of sale price) should be weighed against what they add versus a direct sale process.
- Selling to an Employee Ownership Trust can offer distinct tax advantages worth comparing against a traditional third-party sale.
- If your business value is approaching the £2.5 million Business Relief threshold, your sale timing and your family’s succession plans are now genuinely connected decisions.
Are You Ready to Sell? Decision Framework
- Have you owned the business for at least 2 years? This is generally required for BADR eligibility.
- Is your balance sheet clean of excess non-trading assets? If not, budget time to tidy it up before approaching buyers.
- Does the business run without you being irreplaceable day to day? Buyer confidence — and valuation — drops sharply for owner-dependent businesses.
- Have you had a professional valuation, not just a rough guess? Get this before you set price expectations with anyone.

Frequently Asked Questions
How do I sell a business in the UK?
You typically prepare clean accounts, get a valuation, decide your exit structure, find a buyer, complete due diligence, then negotiate and sign a sale agreement before completing.
What is Business Asset Disposal Relief and how much does it save?
BADR reduces Capital Gains Tax to 18% on qualifying gains up to a £1 million lifetime limit, following the rate change effective 6 April 2026, versus standard rates of up to 24%.
How is a small business valued in the UK?
Most commonly through an earnings-based approach — adjusted EBITDA multiplied by an industry-standard multiple — though the right method depends on sector, size and purpose.
Is it better to sell assets or shares?
Sellers often prefer share sales for the tax treatment; buyers often prefer asset sales for more control and fewer inherited liabilities — expect this to be a genuine negotiation point.
How long does it take to sell a business in the UK?
It varies significantly, but meaningful preparation typically takes a year or more before a sale, with the transaction itself often taking several months from finding a buyer to completion.
Do I need a business broker to sell?

In Summary
Selling a business well is mostly a preparation problem, not a negotiation problem — the owners who plan a year or more ahead consistently get better outcomes than those who start looking for a buyer the moment they decide to leave. The 2026 BADR change makes the tax side more favourable than it’s been in years, but only for sales structured correctly from the start.
