Heads of Agreement for a UK Business Sale

When a business sale starts to feel real, many owners move too quickly from a broad commercial discussion to a draft sale agreement. That is where deals often go off track. A buyer may think key points are already settled when they are not, a seller may treat a “non-binding” document as harmless when it contains binding clauses, and both sides may spend time and money on due diligence without agreeing the basic structure first.

Heads of agreement for business sale can help avoid that problem, but only if they are drafted with care. Get them wrong, and you can create confusion about price, exclusivity, confidentiality, deposits, completion timing, or what is actually being sold. Get them right, and they give both sides a practical framework for the rest of the transaction.

This guide explains what heads of agreement mean for UK businesses, what legal issues to check before you sign, and the mistakes that commonly cause trouble in small and mid-sized business sales.

Overview

Heads of agreement set out the main commercial terms of a proposed business sale before the full legal documents are negotiated. In the UK, they are often partly non-binding and partly binding, so the wording matters more than many business owners expect.

• Identify whether the deal is a share sale or an asset sale.
• State the headline price and how it is calculated or adjusted.
• Record any deposit, deferred consideration, earn-out, or retention arrangements.
• Clarify which clauses are intended to be legally binding, such as confidentiality or exclusivity.
• Set a timetable for due diligence, drafting, approvals, and completion.
• Note any conditions, including landlord consent, third party consents, finance, or regulatory points.
• Describe what is included in the sale, such as contracts, stock, equipment, goodwill, intellectual property, and employees where relevant.
• Reduce the risk of later argument by matching the document to what was actually agreed in meetings and emails.

What Heads of Agreement for Business Sale Means For UK Businesses

Heads of agreement are a roadmap for the deal, not a substitute for the sale contract. They help the buyer and seller confirm the structure of the transaction before either side invests heavily in legal drafting, due diligence, or adviser costs.

In practice, this document often appears after initial negotiations but before the full business sale agreement, asset purchase agreement, or share purchase agreement is prepared. For founders and SME owners, it is the point where a verbal understanding gets turned into a written framework.

What are heads of agreement?

Heads of agreement, sometimes called heads of terms or a memorandum of understanding, summarise the main points the parties have discussed. They usually cover the key commercial terms and the process for moving toward exchange and completion.

They are especially useful where the sale is complex enough that both sides need certainty on the broad shape of the transaction, but are not yet ready to sign the full legal documents.

Why use them in a business sale?

The main benefit is clarity. Before you sign a full sale agreement, you want to know whether you are both talking about the same deal.

That usually means recording points such as:

• who the buyer and seller are
• whether the buyer is acquiring shares or specific business assets
• the agreed price or valuation method
• how payment will be made
• what due diligence will happen
• the intended timetable
• whether the buyer has a period of exclusivity
• which obligations are legally binding straight away

For a seller, that can stop a buyer trying to reopen basic commercial points after significant time has passed. For a buyer, it can stop the seller shopping the deal around while due diligence is under way, if an exclusivity clause is included.

Are heads of agreement legally binding?

Some clauses can be binding even when the rest of the document is not. This is where founders often get caught.

In many UK business sales, the parties intend the main commercial terms to be non-binding, subject to contract and due diligence. At the same time, they may want certain clauses to take legal effect immediately, especially:

• confidentiality
• exclusivity
• costs provisions
• governing law and jurisdiction
• access rights for due diligence

If the wording is vague, one party may later argue that more of the document was binding than the other expected. That is why the document should state clearly which provisions are intended to be binding and which are not.

What should the document cover?

The right content depends on the transaction, but most heads of agreement for business sale should deal with the core structure of the proposed deal.

That often includes:

• the parties and any group companies involved
• the business being sold
• whether it is a share sale or asset sale
• the price and payment mechanics
• excluded assets or liabilities, if any
• treatment of stock, debtors, creditors, and cash
• employees and any planned transfer arrangements where relevant
• any required third party consents
• timetable, milestones, and target completion date
• confidentiality and exclusivity terms
• conditions to the deal proceeding

Where there is goodwill, brand value, software, designs, or other intellectual property in the business, the document should also make clear whether these rights are part of the sale. If trade marks are registered in a separate company, or software is licensed rather than owned, that should be identified early.

Asset sale or share sale?

This is one of the first points to settle because it affects almost everything else. A share sale usually means the buyer acquires the company itself, with its assets and liabilities. An asset sale usually means the buyer picks specific assets and sometimes selected liabilities, leaving the selling company behind.

If the heads of terms are unclear on this, the legal drafting can head in the wrong direction from day one. That wastes time, increases fees, and can create mistrust before the real negotiations begin.

Legal Issues To Check Before You Sign

Before you sign heads of agreement, you need to know exactly what has been agreed, what is still open, and what legal consequences attach immediately. The biggest risk is assuming the document is just a formality when it may shape the whole transaction.

Binding and non-binding wording

The document should say, in plain terms, which parts are legally binding and which are not. A statement that the main deal terms are “subject to contract” is common, but that phrase should not be left to do all the work.

It is better to spell out the position clearly, for example by identifying separate binding clauses and stating that the remaining provisions record current intentions only.

Exclusivity period

If a buyer is spending money on accountants, solicitors, and due diligence, they often want a period in which the seller cannot negotiate with other bidders. That can be commercially sensible, but the scope needs to be specific.

Check points such as:

• how long the exclusivity period lasts
• whether the seller can respond to unsolicited approaches
• what conduct is prohibited during exclusivity
• whether any remedy is available if the clause is breached

Sellers should be careful not to agree to a long lock-out period without clear milestones. Buyers should avoid paying costs on the basis of exclusivity wording that is too vague to enforce.

Price mechanics

A headline price is not enough if the calculation can change later. Before you sign, make sure the heads of agreement explain whether the price is:

• a fixed amount
• subject to a completion accounts adjustment
• based on locked box principles
• partly deferred
• linked to performance under an earn-out
• subject to retention or escrow arrangements

If the price includes future payments, the trigger events and measurement rules need care. Earn-outs often cause disputes because the parties have different expectations about how the business will be run after completion.

What is included in the sale

Do not rely on shorthand descriptions such as “the whole business” unless everyone genuinely knows what that means. For an asset sale, list the categories of assets and identify anything excluded.

Think about:

• stock and work in progress
• customer contracts and supplier agreements
• business names and goodwill
• registered and unregistered intellectual property
• domain names, software licences, and databases
• equipment and vehicles
• books and records
• cash, debtors, and creditors

If an asset cannot be transferred without consent, such as a lease or a customer contract with assignment restrictions, the heads of agreement should reflect that risk.

Employees and management handover

Employees are often one of the most sensitive parts of a business sale. In an asset sale, transfer rules may apply. In a share sale, the employing company usually remains the same, but the buyer will still want to understand contracts, benefits, disputes, and key staff retention.

If the seller is expected to stay on for a handover period, or the founders will sign consultancy or service agreements after completion, the heads of agreement should mention that early. Otherwise the parties may discover late in the process that they had very different expectations.

Property and landlord consent

If the business operates from leased premises, do not leave the lease issue until the final stage. A landlord may need to consent to assignment, grant a new commercial lease, or approve a change of control position depending on the transaction structure.

Before you sign, check whether the deal depends on:

• lease assignment consent
• a new lease being agreed
• licence to assign terms
• release of the seller from ongoing obligations
• property due diligence on title, use, and compliance matters

Due diligence and conditions

Buyers often assume they can walk away if due diligence reveals a problem. That may be true in practice if the main terms are non-binding, but the heads of agreement should still describe the process clearly.

Typical conditions include:

• satisfactory legal, financial, and commercial due diligence
• board or shareholder approval
• third party consents
• finance approval
• no material adverse change before completion

If a condition is important enough to affect whether the deal proceeds, say so. That avoids arguments later about whether a point was fundamental or merely something to tidy up in drafting.

Confidentiality and announcements

Business sale talks can unsettle staff, customers, and suppliers if they leak too early. Confidentiality clauses should deal with what can be disclosed, to whom, and when.

It also helps to cover announcements. If one side plans to tell employees, investors, or key customers at a certain stage, that should be agreed in advance.

Common Mistakes With Heads of Agreement for Business Sale

The most common mistakes come from treating heads of agreement as casual paperwork. In reality, they set expectations, shape legal drafting, and can create binding obligations long before completion.

Leaving the structure unclear

If the document does not clearly say whether the transaction is a share sale or asset sale, negotiations can drift into confusion. Different advisers may then draft on different assumptions.

This often happens where the parties agree a price in principle before discussing liabilities, employees, leases, and tax treatment. Even if the commercial relationship is friendly, that gap usually causes trouble later.

Using vague language around price

“Purchase price to be agreed after due diligence” is often too loose to be useful. It may record very little more than an intention to keep talking.

A better approach is to define the baseline now. If adjustment is expected, explain the mechanism and the broad accounting approach so there is less room for later surprise.

Forgetting what is meant to be binding

Many owners sign heads of terms believing the whole document is non-binding, only to discover the exclusivity or costs clause has immediate legal effect. The reverse also happens, where a party expects the other side to be locked into the deal terms but the wording does not support that view.

The fix is simple but often missed: say exactly what is binding, what is not, and when the parties intend to be legally committed.

Ignoring third party consents

A business may look sale-ready until someone checks the lease, finance documents, franchise terms, software licence, or major customer contract. If consent is required and not obtained, completion can be delayed or blocked.

This is especially important in smaller deals where the value of the business sits in a few key contracts. A buyer may think they are buying a stable customer base, but those customer contracts may not be transferable without consent.

Not matching the document to the real deal

Sometimes the written heads of agreement are copied from another transaction and do not reflect what the parties actually discussed. That creates friction fast.

For example, the seller may expect cash on completion, but the heads refer to deferred payments. Or the buyer may assume the founders will stay for six months, but the document says nothing about transition support. Before you rely on a verbal promise, make sure it appears in the written heads if it matters to the deal.

Overlooking timing and process

A sale can lose momentum if there is no agreed timetable. Equally, unrealistic dates can create pressure and poor decisions.

Useful process points to include are:

• when due diligence starts and ends
• who prepares the first draft sale agreement
• target dates for comments and negotiation rounds
• when third party consents will be sought
• the intended completion date

Even if these dates move, they help both sides manage expectations and adviser costs.

Assuming standard wording is safe

Template wording can be a useful starting point, but business sales are rarely identical. A technology business with licensed software, a retail business with leased sites, and a service business built on founder relationships each have different pressure points.

The heads of agreement should reflect the actual value drivers and risks in the target business, not just generic legal language.

FAQs

Are heads of agreement required for a UK business sale?

No. A sale can proceed without them. But they are often useful where the parties want to record the main commercial terms and avoid wasting time on full drafting before the basics are settled.

Can either side pull out after signing heads of agreement?

Often yes, if the main deal terms are expressly non-binding and subject to contract. But binding clauses, such as confidentiality or exclusivity, may still apply, so the document needs careful review.

What is the difference between heads of agreement and the sale agreement?

Heads of agreement summarise the proposed deal at a high level. The sale agreement is the detailed legal contract that sets out the final binding terms, warranties, indemnities, completion mechanics, and risk allocation.

Should a small business sale still use heads of terms?

Often yes, especially if there is deferred payment, property, employees, key contracts, or a handover period. Even in smaller deals, written heads can prevent misunderstandings before legal costs increase.

How long should heads of agreement be?

They should be long enough to capture the real commercial deal, but short enough to stay clear and practical. For many SME transactions, a focused document covering structure, price, conditions, timing, and binding clauses is more useful than an over-detailed draft.
