Key Steps to Selling Your Business in the UK: A Practical Guide

Most business owners spend years building something valuable. When it comes time to sell, many assume the hard part is already done. You've built the business. Surely finding a buyer and handing over the keys is the easy bit?

It's not. Following the right steps to sell a business in the UK makes the difference between a deal that completes and one that collapses. The full process typically takes 6 to 12 months for well-prepared sellers. For complex transactions involving multiple shareholders, property assets, or earn-out structures, it can stretch to 18 months.

Here's the uncomfortable truth: 90% of businesses that fail to sell do so because of an inflated asking price. Not because there are no buyers. Not because the market is poor. Because the seller had unrealistic expectations and refused to adjust.

These eight steps cover the full process from early preparation through to completion. Whether you're planning to sell in the next six months or just starting to think about an exit, understanding what's ahead — including the traps that catch unprepared sellers — puts you in a much stronger position.

The sellers who get the best outcomes aren't necessarily the ones with the biggest businesses. They're the ones who treat the sale as a project, plan methodically, and get proper advice at each stage.

Preparation is where deals are won or lost. It starts long before any buyer appears. Ideally, you want 12 to 18 months of dedicated preparation before going to market. The businesses that attract the strongest offers and complete fastest are the ones that did this groundwork.

Get your financials clean

Buyers will scrutinise your accounts. Having three years of audited or professionally prepared accounts is the single most effective thing you can do to speed up a sale. Sellers with three years of audited accounts tend to close significantly faster than those scrambling to produce financials during due diligence.

Your accounts should clearly show revenue trends, gross margins, operating profit, and normalised EBITDA with documented adjustments. If your accounts mix personal expenses, unclear related-party transactions, and inconsistent categorisation, fix that now, not when the buyer asks.

Reduce owner dependence

If the business can't run without you, it's worth less. Buyers pay a premium for capable management teams, documented processes, and customer relationships not tied to the founder's personal network. Start delegating key relationships, hiring or promoting a strong number two, and putting operational procedures in writing.

Sort contracts and legal housekeeping

Are your key customer contracts assigned to the company or to you personally? Are supplier agreements current and transferable? Do you have up-to-date employment contracts for all staff? Are lease arrangements properly documented?

These details seem mundane, but unresolved legal issues are one of the most common causes of delay and price reduction during a business sale. Understand how buyers assess business value before you begin.

Clean the balance sheet

Settle outstanding disputes, collect overdue receivables, dispose of redundant assets, and close down any dormant subsidiaries. A clean, simple corporate structure reduces the buyer's perceived risk, which translates directly to price.

Address obvious problems upfront

Every business has issues. Buyers expect that. What they don't tolerate is discovering problems during due diligence when the seller clearly knew about them. If there's a pending lawsuit, a key client threatening to leave, or a regulatory issue, address it before you go to market — or disclose it upfront with a credible plan for resolution.

You think your business is worth more than it is. Nearly every owner does. The emotional investment of building something over years creates a natural bias. That bias is the biggest deal-killer in UK business sales.

A professional valuation gives you an objective anchor. It's not about what you feel the business is worth. It's about what the market will actually pay.

How UK business valuations work

Most UK SME valuations use an EBITDA multiple approach: normalised EBITDA multiplied by a sector-appropriate multiple equals your enterprise value. The average UK mid-market EBITDA multiple sits around 5.3x, but this varies enormously by sector, size, and business quality. A SaaS company with £1m in recurring revenue might trade at 10x or higher. A traditional retail shop might struggle to achieve 3x.

Factors that push your multiple up or down:

• Recurring revenue commands a meaningful premium over project-based income
• Consistent double-digit growth attracts buyers willing to pay more
• Customer concentration above 25% of revenue triggers a discount
• A business that runs without the owner is worth more than one that doesn't
• Sector tailwinds matter — growing markets attract higher multiples

A good corporate finance adviser will draw on EBITDA multiples, discounted cash flow analysis, and asset-based approaches. The output will be a range — "enterprise value between £1.8m and £2.3m" — not a single number.

For independent benchmarking data on UK M&A multiples, the ICAEW Corporate Finance Faculty publishes regular market analysis that's worth reviewing alongside any adviser's valuation.

Valuation is not the same as asking price. Your asking price might sit at the top of the range if market conditions are strong, or you might price slightly below to generate competitive tension among buyers. That's a strategic decision you'll make with your adviser.

Should you use a business broker, a corporate finance adviser, or sell directly? It depends on your business's size, complexity, and your own capacity to manage the process.

Business brokers

Business brokers handle the majority of UK small business sales — companies valued below roughly £1m. They market your business, screen enquiries, arrange viewings, and help with negotiations. Broker fees typically run between 8% and 10% of the deal value, though the full range is 1.5% to 12% depending on size and complexity. Some charge an upfront retainer plus a success fee; others work on a purely contingent basis.

The right broker makes an enormous difference. Look for brokers who specialise in your sector or deal size, ask for references from completed transactions, and understand exactly what their fee covers.

Corporate finance advisers

Corporate finance advisers are the better fit for businesses valued above £1m. They're more expensive but the service is more sophisticated: structured sale processes, competitive auctions, deal structuring advice, and hands-on management through to completion. Advisory fees typically run 2% to 5% plus a retainer.

Going direct

Going direct saves on fees but demands significant time and expertise. You'll need to identify potential buyers yourself, produce all marketing materials, manage confidentiality, handle negotiations, and coordinate legal and financial due diligence — all while continuing to run the business.

For straightforward transactions where you already know the likely buyer, direct sale can work well. For anything requiring a broad market search, it's a stretch for most owner-managers.

Check NewOwner's listing options to reach buyers directly, either as your primary route to market or alongside a broker engagement.

Confidentiality is non-negotiable. If your staff, customers, suppliers, or competitors find out you're selling before you're ready to announce it, the consequences can be severe. Key employees start looking for other jobs. Customers question whether to stay. Competitors smell blood. All of this destroys value at exactly the moment you're trying to maximise it.

The information memorandum

This is your core sales document — a detailed presentation covering the business's history, financial performance, market position, growth opportunities, and reason for sale. A well-crafted IM is typically 20 to 40 pages and presents the business in its best honest light. Experienced buyers can spot puffery instantly, and it undermines credibility.

The teaser profile

Before showing anyone the IM, your broker will circulate a one-page anonymised summary — enough to generate interest without revealing the company's identity. Interested parties sign a non-disclosure agreement (NDA) before they see anything further.

Listing on business-for-sale platforms

Online marketplaces are a standard channel for reaching potential buyers. Your listing should be anonymised but specific enough to attract the right type of buyer — industry, region, revenue range, and a brief description of the opportunity.

You can list your business for sale on NewOwner with full control over what information is visible publicly and what's shared only after an NDA is signed.

Direct approaches to likely buyers

For certain businesses, the right buyer might be a competitor, a trade player expanding into your region, or a PE-backed platform doing acquisitions in your sector. Your adviser can approach these parties directly and discreetly, under NDA, without any public listing.

The best sale processes use multiple channels simultaneously. A confidential listing catches buyers actively searching. Direct approaches find buyers who weren't looking but would be interested.

Not every enquiry deserves your time. Most won't lead anywhere, and entertaining time-wasters who lack the funds or genuine intention to buy is one of the biggest mistakes sellers make.

Three things to check before investing serious time

Financial capability comes first. Can they actually afford the business? You don't need to demand bank statements on day one, but you do need to understand how they plan to fund the purchase. Cash buyer? Bank-financed? PE-backed? An offer from someone who hasn't secured funding isn't worth much.

Strategic fit matters too. Why do they want this particular business? Buyers with a clear strategic rationale — expanding into your region, adding your services to their existing offering, acquiring your customer base — are more likely to complete than those who are "just looking at opportunities."

Track record tells you something useful. Have they bought a business before? First-time buyers aren't necessarily a problem, but they tend to be slower, more nervous, and more likely to walk away during due diligence.

Managing viewings and management presentations

Once you've qualified a shortlist, site visits and management presentations follow. These are your chance to show the business at its best — but also the buyer's chance to assess you and your team. Be prepared for detailed questions about customers, staff, competitors, and financial performance. Rehearse your answers. Have the data to hand.

A structured process — where multiple qualified buyers view the business on a similar timeline — creates competitive tension and gives you the strongest negotiating position. If a buyer knows they're the only party at the table, their incentive to offer a fair price drops significantly.

The offer stage is where emotions run highest and the most value is at stake. A well-handled negotiation can add hundreds of thousands of pounds to the final price. A poorly handled one can collapse the deal entirely.

Offers typically come as a heads of terms (HoT) document — sometimes called a letter of intent. This is a non-binding summary of the proposed deal structure.

What heads of terms cover

Element	What to watch
Purchase price	How it's calculated (e.g., 5.5x normalised EBITDA)
Deal structure	Share sale vs asset sale — affects tax significantly
Payment terms	Cash at completion, deferred consideration, earn-out
Conditions	Due diligence, financing, regulatory approvals
Exclusivity period	Typically 6-12 weeks — negotiate this carefully
Completion timeline	Target date for getting the deal done

Don't fixate on the headline price. A £2m offer with clean terms and a four-week completion beats a £2.3m offer that's 40% earn-out, contingent on hitting aggressive targets, and takes six months to close.

Earn-outs: the detail matters

Earn-outs are common in UK business sales, particularly where the buyer wants the seller to stay on during a transition period. The principle: part of the price depends on the business hitting agreed performance targets after completion.

But the devil is in the detail. How are targets defined? Who controls the business decisions that affect whether targets are met? What happens if the buyer changes strategy or integrates the business into a larger group? Get your solicitor to scrutinise every word of the earn-out clause.

One tactical point: granting exclusivity too early, or for too long, weakens your position. Once a buyer has exclusivity, they know you're off the market. Keep the exclusivity period as short as practical — four to six weeks for a straightforward deal — and include a clear timetable with milestones.

Due diligence kills more deals than any other stage — and it's the stage sellers are least prepared for. It typically runs 8 to 12 weeks and involves the buyer and their advisers examining every aspect of your business in exhaustive detail.

Four areas of scrutiny

Financial due diligence covers your accounts, management information, tax returns, cash flow, working capital, debtor and creditor ageing, and normalised EBITDA adjustments. The buyer's accountants are looking for risks: declining margins, customer concentration, cash flow issues, or EBITDA adjustments that don't hold up.

Legal due diligence examines contracts, leases, employment agreements, intellectual property, regulatory compliance, litigation history, corporate structure, and shareholder arrangements. Any skeleton in the legal cupboard will be found. Disclosing known issues upfront is always better than having the buyer's solicitor discover them.

Commercial due diligence looks at market position, competitive dynamics, customer relationships, sales pipeline, supplier dependencies, and growth prospects. Some buyers conduct customer reference calls — with your permission — to validate revenue quality.

Operational due diligence covers IT systems, key person dependencies, premises, equipment condition, health and safety compliance, and environmental liabilities.

Preparing a virtual data room

The virtual data room (VDR) is the tool that makes due diligence manageable. Prepare it before you accept heads of terms, with everything organised, indexed, and clearly labelled. Sellers who drip-feed documents in response to individual requests slow the process and frustrate the buyer's advisory team.

The most common due diligence findings that trigger price reductions: EBITDA adjustments the buyer doesn't accept, working capital below the agreed target level, undisclosed liabilities, and key customer contracts that are weaker than represented. Anticipate these issues and address them before the buyer raises them.

Once due diligence is substantially complete and any price adjustments are agreed, you move to legal documentation. This is where solicitors earn their fees.

The core document is the sale and purchase agreement (SPA). For a share sale, the SPA covers warranties, indemnities, restrictive covenants, and completion mechanics.

Warranties and indemnities

Warranties are statements you make about the condition of the business — the accuracy of accounts, the status of contracts, the absence of litigation, compliance with laws. If any warranty turns out to be untrue, the buyer can claim against you for losses. Your solicitor will push to limit the scope, duration, and financial caps on warranty claims.

Indemnities are specific guarantees to compensate the buyer for known risks — a pending tax investigation, an unresolved employment claim, or an environmental liability. Unlike warranties, indemnities provide pound-for-pound compensation for identified issues.

Restrictive covenants

The buyer will want to prevent you from setting up a competing business, soliciting newly acquired customers, or poaching staff. Non-compete periods of 2 to 3 years are standard in UK business sales.

Share sale vs asset sale

This is a fundamental structural decision. In a share sale, the buyer takes on the company with all its assets, liabilities, contracts, and history. In an asset sale, they cherry-pick specific assets and leave the rest with you. Sellers generally prefer share sales for tax efficiency — you pay Capital Gains Tax on the share disposal. Buyers often prefer asset sales because they can avoid inheriting unknown liabilities.

Expect the legal process to take 4 to 8 weeks from SPA drafting to completion. It can take longer if warranties are heavily contested or if there are complex property or regulatory elements.

The money's in your account and the deal is done. But there's still work to do.

Tax planning — get this right before completion

The tax treatment of your sale proceeds depends on the deal structure and your personal circumstances. For a share sale, the headline rate is Capital Gains Tax. For higher-rate taxpayers, the standard CGT rate is 24%. But if you qualify for Business Asset Disposal Relief (BADR), you pay a reduced rate on the first £1m of qualifying gains.

From April 2026, the BADR rate rises to 18%, up from 14% in the previous year. That's still a meaningful saving — 6 percentage points below the standard higher rate. The lifetime limit remains £1m.

To qualify for BADR, you need to have held at least 5% of the shares and voting rights, been an officer or employee of the company, and the company must have been a trading company — all for at least two years before the sale. Missing the qualifying conditions by a technicality is an expensive mistake.

For detailed HMRC guidance on BADR, see GOV.UK's Business Asset Disposal Relief page.

Other tax considerations: Inheritance Tax planning if you're passing proceeds to the next generation, the interaction between earn-out payments and annual CGT allowances, and whether consultancy fees during handover should be structured as income rather than capital.

The handover period

Most buyers will want you to stay on for a transition period — typically 3 to 12 months, depending on the complexity of the business and how owner-dependent it is. Be generous with your knowledge. Introduce the new owner to every key customer, supplier, and partner personally. Document everything that lives in your head: the informal processes, the relationship dynamics, the institutional knowledge that never made it into the IM.

Moving on

Selling a business you've built is an emotional event. The financial gain is real, but so is the sense of loss. Many sellers describe the first few months after completing a sale as surprisingly difficult, even when the deal was excellent.

Plan your next chapter before you complete the sale, not after. Having something to move towards makes letting go immeasurably easier.
