How to Sell a Business in the UK: 2026 Step-by-Step Seller's Guide

Deciding to sell your business is one of the biggest decisions you'll make. If you've been wondering how to sell a business in the UK the right way, without leaving money on the table or spending years in limbo, this guide walks you through every stage, from initial valuation to completion day.

Here's the short version: to sell a business UK-wide takes 6–12 months and involves eight core steps: valuation, preparation, tax planning, choosing a route to market, creating your information memorandum, finding and qualifying buyers, negotiating heads of terms, and completing the sale. Each step matters. Skipping one shows up later, at the worst possible moment.

This guide covers every stage in detail.

Timing a business sale well can be worth hundreds of thousands of pounds. When you're mapping out the business sale process, timing is the single biggest variable most sellers underestimate. Get it wrong and you're selling a declining asset to a buyer who senses weakness.

Why sellers decide to exit in 2026

Owners typically sell for one of four reasons: retirement, burnout, a better opportunity elsewhere, or a market window they don't want to miss. Understanding why you're selling shapes how you sell. A retirement-driven exit can afford to wait 18 months for the right buyer. A burnout-driven sale needs a faster process and a realistic price. Be honest with yourself about the reason — buyers will ask, and an inconsistent answer damages your credibility.

Market timing

Sellers thinking about selling their company right now face a market that held up strongly in 2025, with sub-£100 million deals making up 88% of all disclosed-value transactions according to Dealsuite's M&A Monitor. Average EBITDA multiples across UK SMEs reached 5.35x in 2025, with high-growth sectors like technology and healthcare hitting 8x and above. If your sector is in a buyer-demand surge, that's the window you want.

Interest rates matter too. When debt is cheap, acquirers can finance deals more easily, which supports higher valuations. Watch the Bank of England base rate. Sellers who timed their exit for periods of accessible credit got better terms.

Personal timing

A lot of sellers wait too long. Burnout is real, and a tired, disengaged owner is visible to buyers during due diligence. If you're ready to retire, move on, or pursue something new, start the process two to three years before you'd ideally step away. Waiting until you're exhausted is a mistake.

Family succession is another trigger. If you're planning to pass the business to children or a management team, doing it while you still have energy to manage the transition is far better than handing over a business you've mentally already left.

Business timing

The best time to sell is when your business doesn't need you. Two to three years of growing EBITDA. A management team that runs operations. Documented processes that are not locked in your head. That is what buyers pay multiples for.

If revenue is rising, margins are holding, and you've got recurring or contracted income, you're in the strongest position. Trying to sell during a downturn or when a major customer has just left is hard work and leads to a low offer or no offer at all.

Before anything else, understand what you're actually selling. The deal structure is the first fork in the road for how to sell a business in the UK, and it shapes the tax bill, the buyer's appetite, and the legal complexity.

Share sale

In a share sale, the buyer acquires the company itself: its shares, contracts, employees, liabilities, and everything else. For sellers, this is the preferred structure because it's clean. You hand over the shares, and the company's history, debts, and contracts transfer with it.

Share sales also qualify for Business Asset Disposal Relief (BADR), which reduces Capital Gains Tax to 18% (from April 2026) on qualifying gains up to a £1 million lifetime limit. That's a substantial saving compared to paying standard CGT rates. For a detailed breakdown of how BADR works and who qualifies, see our Business Asset Disposal Relief 2026 guide.

Asset sale

In an asset sale, the buyer picks specific assets from your business — equipment, goodwill, contracts, stock — without taking on the legal entity itself. Buyers prefer this because they can leave unwanted liabilities behind. For sellers, it's more complicated. You'll still own the company after the sale, and you'll need to wind it down or deal with any remaining liabilities yourself.

The tax treatment is also less favourable. Each asset may be taxed differently, and BADR does not apply to the full amount.

MBO, MBI, and family succession

A management buyout (MBO) happens when your existing management team acquires the business. It's smoother operationally since they already know the business, but financing can be tricky. Management teams rarely have the capital and need private equity or bank funding to complete the deal.

A management buy-in (MBI) is similar but involves an external management team coming in. Family succession is a fourth option, often treated more informally but still needing proper legal and tax structure to avoid nasty surprises later.

Choosing the right structure upfront, with input from your accountant and solicitor, can save you a substantial amount in tax and legal fees.

These eight steps are the repeatable playbook for selling your UK business in 2026, whether you are selling a £250k lifestyle business or a £5m trading group. Before the steps, here is the preparation timeline most successful UK sellers follow when they decide to divest their business without leaving money on the table.

Stage	Months before sale	Key action	Typical cost
Shape up financials	18–24 months	Clean up accounts, remove owner add-backs, install proper management reporting	£2k–£5k (accountant)
Reduce owner dependency	12–18 months	Document processes, hire or promote a second-in-command	£0–£40k (hire)
Tax planning (BADR, structure)	12 months	Confirm 5% shareholding, trading-company status, any pre-sale extractions	£1k–£3k (specialist adviser)
Commission valuation	6–9 months	Independent EBITDA-multiple valuation and defensible asking price	£1.5k–£5k
Draft Information Memorandum	3–6 months	Polished IM, data room, NDA template, teaser	£2k–£8k
Go to market	0–3 months	List with broker or marketplace, qualify buyers, screen NDAs	0 (upfront)
Heads of terms and DD	0–3 months post-offer	Exclusivity, data room opened, Q&A, site visits	£3k–£10k (legal)
SPA, completion, handover	1–3 months	Signed SPA, funds flowed, handover and any earn-out	£8k–£25k (legal + tax)

The sellers who achieve the top prices typically start this preparation 18–24 months before going to market.

Step 1: Get a professional valuation

The first rule of the business sale process at a defensible price: you can't price what you haven't measured. A professional valuation gives you a defensible asking price and helps you understand what buyers will actually offer, rather than what you hope they might.

Most UK SME valuations use an EBITDA multiple, 3x to 8x depending on sector, size, and risk profile. Other methods include asset-based valuation (useful for property-heavy or asset-rich businesses) and revenue multiples (common in SaaS or subscription models). For a thorough look at how each method works, read how to value a business in the UK and our deep dive on normalised EBITDA adjustments. To see what your specific business is realistically worth, use our UK business valuation guide.

Fair warning: sellers almost always overvalue their own businesses. Getting an independent view, even if it stings, is better than starting a sale process with an inflated price that scares buyers away.

Step 2: Prepare your business for sale

One of the hardest parts of selling your company at full value is preparation: buyers pay premiums for businesses that are ready. That means clean, audited or accountant-certified financials going back three years. Documented processes that don't live entirely in the owner's head. A management team capable of running things without you.

Areas to tidy up before you go to market:

• Three years of profit and loss accounts and balance sheets, ideally reviewed by an accountant
• Leases, supplier contracts, and customer agreements that are transferable
• Up-to-date company records, filed accounts at Companies House, no outstanding HMRC correspondence
• Any IP, trademarks, or assets properly registered in the company's name, not personally

Owner dependency is the single biggest value killer. If the business stops when you stop, buyers either walk or offer a price that reflects the risk.

Step 3: Sort your tax planning before you go to market

Tax planning after you've agreed a deal is too late. In divesting your business profitably, this is the single biggest lever most sellers ignore. Do it before you go to market.

The most important relief for most UK business sellers is Business Asset Disposal Relief (BADR). From April 2026, the BADR rate is 18% on qualifying gains, still well below standard CGT rates of 24% for higher-rate taxpayers. But you need to check your eligibility in advance: you must have owned at least 5% of the company shares for two years, be an employee or officer, and the company must be a trading company.

Also worth discussing with your accountant: whether a share sale or asset sale is more tax-efficient for your specific situation, whether any restructuring would help (for example, extracting pre-sale cash or property before completion), and whether your pension can be used as part of the deal structure.

Get proper advice from a specialist M&A accountant, not your general bookkeeper.

Step 4: Choose your route to market

When it comes to selling your UK business, you have four main options for finding buyers:

A business broker manages the process, creates your marketing materials, approaches buyers, and handles early negotiations. Fees vary widely: expect a success fee of 5–12% for smaller deals, or a lower percentage plus an upfront retainer for larger transactions. Brokers add value if they have sector expertise and a genuine buyer network. Before you sign on, run the maths in our NewOwner vs UK business brokers comparison — on a £500k sale broker fees can take £60k+.

An online marketplace like NewOwner lets you list your business and reach thousands of buyers directly, at a fraction of the cost. This works particularly well for SMEs under £5 million in value where the deal is relatively straightforward. You keep control of enquiries and negotiations.

A direct approach means approaching trade buyers or competitors directly, often in confidence. This requires care. You do not want word getting back to employees or customers before you are ready.

Private equity is an option if your business has strong recurring revenue and growth potential. PE firms invest in businesses with EBITDA above £500k and look for a clear path to growth post-acquisition.

For a direct comparison of brokers versus marketplace listing, see NewOwner's how to get the best price when selling your business guide.

Step 5: Create your Information Memorandum

The Information Memorandum (IM) is your formal sales document — and the centrepiece of how to sell a business in the UK to qualified buyers. It's what serious buyers read before deciding whether to make an offer. A good IM covers:

• Business overview: what you do, how long you've been trading, main markets
• Financial summary: revenue, gross margin, EBITDA, and normalised (adjusted) EBITDA for the last three years
• Operations: how the business runs day-to-day, team structure, systems
• Growth opportunities: what a new owner could do to grow the business
• Reason for sale: honest and credible. Buyers always ask
• Asking price and deal structure preference

For smaller transactions, this might be 10–15 pages. For larger deals, it can run to 50 pages or more. Your broker or corporate finance adviser will typically draft it; if you're selling without a broker, it's worth commissioning one from an M&A specialist.

Before sending the IM to anyone, get them to sign a Non-Disclosure Agreement (NDA). Every time. Without exception.

Step 6: Find buyers and handle enquiries

The live-market phase is where how to sell a business in the UK turns from theory to practice. Once you're live, you'll start receiving enquiries. Not all of them are serious. Qualifying buyers early saves you weeks of wasted time:

• Have they signed the NDA?
• Do they have access to funding (evidence of funds, confirmation from their bank or PE backer)?
• Have they bought a business before, or at least done serious research?
• Does their stated reason for interest make sense?

For larger deals, you may run a structured process: a first round of indicative offers, then a shortlist invited to management presentations, then best and final offers. For smaller deals, it's more informal but the discipline of qualifying buyers still matters.

In H1 2025, UK SMEs attracted an average of 7.9 interested parties per deal, according to Dealsuite's M&A Monitor data. You'll likely hear from far more tyre-kickers than serious buyers.

Step 7: Negotiate heads of terms, then due diligence and SPA

When you've found a serious buyer, you'll agree Heads of Terms (HoT) — a non-binding document that outlines the main deal parameters: price, structure (shares or assets), earn-out terms if any, exclusivity period, and target completion date.

Then comes due diligence. The buyer's legal and financial advisers will go through your business with a fine-tooth comb: financials, contracts, employee terms, IP, tax compliance, outstanding litigation. This takes 6–12 weeks depending on complexity. Your data room — an organised virtual folder of all critical documents — needs to be ready before this starts.

Once due diligence is complete (or running in parallel), lawyers draft the Share Purchase Agreement (SPA). This is the binding legal contract. It includes warranties (promises you make about the business), indemnities, and mechanisms for price adjustments. Negotiate the warranty positions carefully. Your solicitor will advise what is standard and what is a red flag.

Step 8: Completion, handover, and earn-out

Completion day is when money changes hands and ownership transfers. This usually happens simultaneously with signing the SPA, though sometimes there's a gap.

After completion, there is typically a handover period, anywhere from one month to two years depending on what the buyer negotiated. The longer the earn-out (where part of your payment depends on post-sale performance), the longer you're effectively still working in the business.

Earn-outs are common but carry risk for sellers. Make sure the earn-out metrics are clearly defined, within your control to influence, and properly protected in the SPA. Many sellers have seen earn-outs fail to pay out due to buyer decisions after completion.

Notify HMRC of the disposal and file your CGT return within 60 days of completion, following the GOV.UK Capital Gains Tax on business assets guidance. The British Business Bank's guide to selling your business is a useful complementary read on financing and buyer expectations. The ICAEW Corporate Finance Faculty publishes technical notes on SPA warranty and indemnity standards, and the Federation of Small Businesses has sector-specific guidance for owners preparing an exit.

Working out how to sell a business in the UK isn't free. Here's what to budget for.

For most sellers planning how to sell a business in the UK, the biggest variable cost is the broker. Broker fees range from 1% to 12% of the sale price. For smaller businesses (under £500k), no-sale-no-fee brokers charge 8–12%. For larger deals, brokers may take a retainer of £10,000–£40,000 upfront plus a 3–5% success fee on completion. Some platforms, including NewOwner, charge a fraction of traditional broker fees for listing your business directly to buyers.

Legal fees for selling a business range from £8,000 to £15,000 for simpler deals, and 1% of the sale price or more for complex transactions above £2 million. Your solicitor will draft the SPA, negotiate warranties, manage the disclosure process, and handle completion mechanics. Do not try to cut corners here. The SPA protects you post-completion.

Accountancy fees run to £2,000–£7,000 for preparing financial information, attending due diligence, and advising on the transaction structure. For complex deals with tax structuring, this can be higher.

Warranty and Indemnity (W&I) insurance is increasingly common in UK mid-market deals. It covers buyers against losses from warranty breaches, which means sellers get a cleaner exit. Premiums run 0.8–1.2% of the insured limit.

Total costs for a £1 million business sale can easily reach £50,000–£100,000 when you include all professional fees, so factor this into your net proceeds calculation.

The honest answer to how to sell a business in the UK on a reasonable timeline: longer than you think.

A typical UK business sale takes 6–12 months from going to market to completion. Some well-prepared businesses with motivated buyers close in four to five months. Others drag on for 18 months or more, because something unexpected comes up in due diligence, or the buyer's financing falls through.

Here's a rough timeline:

Stage	Typical duration
Preparation and valuation	1–3 months
Marketing and finding buyers	2–4 months
Offers and heads of terms	2–6 weeks
Due diligence	6–12 weeks
SPA negotiation and completion	4–8 weeks

Things that speed up a sale: being well-prepared before you go to market, having clean financials readily available, having a data room ready to go, and being responsive to buyer enquiries. Things that slow it down: messy accounts, legal disputes, property issues, critical-person risk, or a buyer who keeps finding new concerns in due diligence.

If you need to sell your business quickly, it's still worth getting a valuation and proper preparation rather than rushing to market and accepting the first low offer. An extra four weeks of preparation can be worth tens of thousands of pounds.

Most UK business sales that fail do so for predictable reasons. Across thousands of enquiries on how to sell a business in the UK, the following mistakes come up again and again.

Overvaluing the business is the most common mistake in how to sell a business in the UK at market price. Setting an asking price 40% above what the market will pay does not get you a higher price. It gets you no buyers at all, or buyers who offer 60% of your asking price because they know you are desperate. Base your price on comparable transactions and a real valuation methodology.

Messy financials kill deals. If you cannot produce clean profit and loss accounts for the last three years, buyers get nervous and reduce their offer to compensate for the risk. Worse, they may walk away entirely. Get your accounts in order before you start, even if that means spending a few months cleaning things up first.

Too much owner dependency is another value killer. If you are the main salesperson, the main relationship holder, and the person who signs off every decision, buyers see a business that does not function without you. That is a problem, not a feature. Reducing owner dependency before sale is one of the highest-ROI things you can do.

Leaking the sale early can be catastrophic. Word getting out to staff, customers, or suppliers before you are ready causes real damage. Employees leave. Customers get nervous. Major contracts do not renew. Keep the circle of people who know about the sale as small as possible for as long as possible.

Skipping tax advice is genuinely expensive. The difference between a well-structured share sale with BADR applied correctly and a poorly structured asset sale can be hundreds of thousands of pounds in extra tax.

Negotiating on price alone is shortsighted. Price is important, but deal structure matters just as much. An earn-out, a deferred payment, or unfavourable warranty terms can cost you more than a lower headline number from a cleaner buyer. For more on this, read how to get the best price when selling your business.

When deciding how to sell a business in the UK in 2026, you've got several options for getting your business in front of buyers.

NewOwner is a UK marketplace designed for buying and selling businesses. Sellers list directly and reach thousands of pre-qualified buyers without the overhead of a traditional broker. You control the enquiry process, the price, and the narrative. It works particularly well for SME owners who want visibility and direct buyer access without paying 8–12% commission. List your UK business for sale on NewOwner and your listing goes live within minutes.

Traditional business brokers manage the full process: valuation, marketing, buyer qualification, and negotiation. They are worth considering for complex deals above £2 million, or if you are selling a business in a niche sector where the broker has specific buyer relationships. The trade-off is cost (5–12% success fee) and speed (brokers take weeks or months to go live).

National broker platforms like Rightbiz or BusinessesForSale.com aggregate listings and charge a fixed listing fee. They generate volume but less qualification. Expect a lot of tyre-kickers. We compared all the major UK marketplaces in NewOwner vs BusinessesForSale, Rightbiz & Daltons.

Corporate finance advisers handle M&A at the mid-market level, for deals of £5 million and above. They run competitive auction processes, approach strategic buyers, and manage the full deal lifecycle.

For most UK SME owners selling a business under £5 million, the most cost-effective route is to list on NewOwner while engaging a solicitor and accountant independently. This gives you market exposure at a fraction of traditional broker fees, with proper professional support on the legal and tax side.

Worth knowing: The honest question about how to sell a business in the UK in 2026 isn't "which broker" — it's "what does my after-tax outcome look like under each route?". Model the full picture (BADR, broker fee, timeline) before you sign anything. The sellers who do best on how to sell a business UK-side tend to spend more time on structure than on marketing, and that's the lesson worth carrying into your process.
