Why Enter Into A Heads Of Agreement? (2026 Updated)

If you're in the middle of negotiating a deal - buying a business, partnering with a supplier, raising money, or preparing a big project - you'll often reach a point where everyone agrees on the "big picture", but you're not quite ready to sign the final contract.

That's where a Heads of Agreement (often called a "HoA") can be incredibly useful.

A Heads of Agreement can help you capture the commercial deal in writing, set a clear roadmap for final negotiations, and reduce the risk of misunderstandings when things start moving quickly.

But it's not a magic document - and if it's drafted poorly, it can create the exact problems you were trying to avoid (including accidentally creating a legally binding contract).

Below, we'll walk through why businesses use Heads of Agreement, when they're most helpful, what to include, and the most common legal traps to watch out for in 2026.

What Is A Heads Of Agreement (And Is It Legally Binding)?

A Heads of Agreement is a written document that sets out the key terms that the parties have agreed "in principle", before a full contract is signed.

You'll often see it used where:

• there's broad commercial agreement, but the details still need to be negotiated
• the parties want to start preparatory work (or due diligence) before signing the final contract
• the deal is complex and needs a clear written "summary" so everyone stays aligned

Is A Heads Of Agreement Actually Binding In The UK?

It depends - and this is where you need to be careful.

In UK law, whether a Heads of Agreement is legally binding depends on what it says, how it's written, and what the parties do afterwards. Even if you call a document "Heads of Agreement", that doesn't automatically make it non-binding.

As a general rule:

• Some Heads of Agreement are intended to be non-binding, except for specific clauses (like confidentiality or exclusivity).
• Some are intended to be fully binding (in effect, they operate like a short-form contract).
• Some accidentally become binding because the language, structure, or conduct suggests the parties intended to create legal relations.

If you're unsure where your document sits, it's worth stepping back and checking the basics of contract formation - because the risk is often not what you label the document, but how it reads in substance.

Heads Of Agreement Vs Term Sheet Vs Memorandum Of Understanding

Different industries prefer different names, but these documents often play a similar role.

• A Term Sheet is common in investment and fundraising, and typically summarises commercial and structural terms (like valuation, equity, governance and conditions precedent).
• A Memorandum of Understanding is often used for collaborations, public sector projects, charities, or situations where parties want a clear statement of intent.
• A Heads of Agreement is widely used across commercial deals - from business sales to major supplier arrangements - to document key agreed points while the long-form contract is being prepared.

Practically, the best document is the one that matches your deal and your risk profile - and is drafted clearly enough that everyone understands what is (and isn't) binding.

Why Businesses Use Heads Of Agreement Before The Final Contract

When you're negotiating, it's easy for momentum to outpace clarity. A Heads of Agreement helps slow things down in a good way - by putting the core deal in writing before you get lost in legal drafting and detail.

Here are the most common reasons UK businesses use Heads of Agreement.

1) To Confirm The Commercial Deal (So Everyone Stays Aligned)

A Heads of Agreement is a way of saying: "This is what we think we've agreed - tell us now if you see it differently."

This matters because many disputes don't start with bad behaviour. They start with mismatched assumptions, such as:

• what exactly is being sold or delivered
• what's included in the price (and what isn't)
• timeframes and milestones
• who carries which risks (for example, delays, defects, or regulatory approvals)

Capturing these points early can save you from expensive rework later - or worse, signing a final contract that doesn't reflect the deal you thought you had.

2) To Speed Up The Legal Drafting Phase

Long-form contracts take time because lawyers need clear instructions.

With a Heads of Agreement in place, you can usually:

• reduce back-and-forth on core deal points
• identify "red flag" issues early (like liability caps, IP ownership, or termination rights)
• draft the final contract more efficiently, because the structure is already agreed

In other words, a good Heads of Agreement can make the final contract process feel far less painful.

3) To Set Ground Rules While You Negotiate

Even if the main commercial terms are intended to be non-binding, it's common for a Heads of Agreement to include binding "process" terms that protect you while negotiations are ongoing.

These commonly include:

• confidentiality (so sensitive information shared during negotiations isn't misused)
• exclusivity (so the other party can't shop your deal around for a better offer during a set period)
• costs (who pays their own legal fees, and whether any costs are recoverable)
• governing law and jurisdiction (usually England & Wales, unless there's a cross-border element)

These points can matter just as much as the final contract, because they set the tone and boundaries for the negotiation stage.

4) To Allow Early Work To Begin (Without Waiting For The Full Contract)

Sometimes you can't afford to wait.

For example, you might need to:

• start due diligence on a business acquisition
• begin technical discovery or early scoping work on a project
• reserve resources or lock in a supplier window
• apply for third-party approvals

A Heads of Agreement can document the agreed pathway so both parties feel comfortable moving forward - while still acknowledging that the final contract is coming.

That said, if money is changing hands or work is starting immediately, it's worth checking whether you actually need a binding short-form contract rather than a "mostly non-binding" Heads of Agreement.

When A Heads Of Agreement Makes Sense (And When It Doesn't)

Heads of Agreement aren't compulsory - they're a tool. Used well, they reduce deal friction. Used poorly, they create uncertainty.

Common Scenarios Where A Heads Of Agreement Works Well

A Heads of Agreement is often a good fit if you're dealing with:

• business sales and purchases (especially where there's a due diligence phase and multiple moving parts)
• commercial property deals (where key terms are agreed before formal documentation)
• joint ventures and collaborations (where the parties want to align on structure before drafting complex obligations)
• investment discussions (particularly early-stage or pre-seed arrangements, where terms need to be documented quickly)
• large procurement projects (where the parties want a clear record before a full suite of contracts is prepared)

When You Might Skip The Heads Of Agreement Stage

You might not need a Heads of Agreement if:

• the deal is straightforward and a standard contract can be prepared quickly
• you're at an early "exploratory" chat stage with no real agreement yet
• the other party is pushing for a Heads of Agreement but won't commit to a clear timeline for the final contract (this can become a problem)

One common issue is a Heads of Agreement that sits in limbo: you've documented broad terms, but the final contract never arrives - and then you're left arguing about whether you have an enforceable deal.

This is also why it's important to be careful with language. If you want a non-binding document, you generally need to say so clearly, and structure it properly - otherwise you may end up with a dispute about intention and enforceability (especially where the parties start acting as if there is a contract in place).

What Should You Include In A Heads Of Agreement?

A Heads of Agreement should be tailored to your transaction, but most well-drafted HoAs in 2026 include a mix of commercial terms and process terms.

Below are common clauses to consider.

Key Commercial Terms

• Parties: who is entering the deal (including the correct company names and numbers if relevant).
• Deal scope: what is being bought/sold/delivered, and what is excluded.
• Price and payment structure: amount, timing, deposits, staged payments, adjustments, and whether VAT applies.
• Timelines: target dates, milestones, longstop date, and any dependencies.
• Conditions precedent: what must happen before the final deal completes (e.g. finance approval, board approval, regulatory consent).
• Responsibilities: who is doing what between now and completion (for example, providing documents, arranging inspections, or obtaining consents).

Key Legal Risk Settings (Even At HoA Stage)

Even if your Heads of Agreement is intended to be non-binding on the "main deal", you should still think about the big risk settings that will likely become negotiation points later.

• Liability approach: is there likely to be a cap, or carve-outs for certain losses? (If this will be a major issue, it's better to flag it early than fight about it at the end.)
• Intellectual property: who owns pre-existing IP and who owns new IP created during the relationship?
• Termination position: what happens if either party walks away during negotiations or after signing the final contract?
• Confidential information and data: how information is handled during due diligence and negotiation.

If you're collaborating closely before the final contract, it's also worth thinking about practical data protection steps (for example, if personal data is being exchanged, you may need a more formal data-sharing or processing arrangement beyond a standard confidentiality clause).

Binding Vs Non-Binding Clauses (Be Explicit)

A common approach is:

• state that the document is not intended to be legally binding except for specific clauses, and
• list those clauses and clearly mark them as binding (for example confidentiality, exclusivity, costs, governing law, dispute resolution)

Clarity here matters. If it's ambiguous, you can end up with a dispute about whether you've already done the deal - or whether the other party can walk away without consequence.

Common Legal Traps To Watch Out For (And How To Avoid Them)

Heads of Agreement are meant to reduce uncertainty, but the wrong drafting can increase it.

Here are some common traps we see, and how to avoid them.

Accidentally Creating A Binding Contract

This is the big one.

Even if you intended your Heads of Agreement to be "just a summary", it might become binding if:

• it contains all (or most) of the key deal terms
• it reads like a contract (using firm language like "will" and "shall" without qualification)
• there is no clear statement that it's subject to contract or otherwise non-binding
• the parties start performing the deal immediately (e.g. delivering goods/services, paying money, or acting as if completion has occurred)

Sometimes that's fine - you may actually want a binding agreement. The problem is when you don't realise you've created one, and the document doesn't contain the protections you'd normally include in a full contract.

Vague "Good Faith" Negotiation Obligations

Heads of Agreement often say the parties will negotiate "in good faith".

In principle, that sounds reasonable - but in practice, unclear good faith obligations can create arguments about whether someone negotiated properly or whether they're allowed to walk away.

If you include good faith language, it should be paired with practical boundaries, like:

• a clear timeline for negotiating the final contract
• a process for resolving deadlocks
• clarity on whether either party can terminate negotiations at any time

Not Managing Exclusivity Properly

Exclusivity can be useful (especially in business sales and fundraising), but it needs to be designed carefully.

If you agree to exclusivity, consider:

• how long the exclusivity period lasts
• what behaviour is prohibited (e.g. negotiating with third parties, soliciting offers, providing information)
• what happens if the other party drags their feet
• whether you need a break fee or cost recovery if the deal doesn't proceed

A vague exclusivity clause can leave you stuck - unable to pursue other opportunities, while the other side takes their time.

Assuming The HoA Replaces The Final Contract

A Heads of Agreement is usually a stepping stone, not the destination.

If you start operating your relationship based purely on a Heads of Agreement, you can end up exposed on important points that are typically handled in the long-form contract, such as:

• service levels and acceptance criteria
• indemnities and liability carve-outs
• intellectual property and licensing rights
• non-solicitation and restraint clauses
• dispute resolution mechanisms

If your arrangement is moving fast, you might instead consider putting a short-form binding contract in place while you negotiate the "full" agreement - or ensuring your Heads of Agreement is drafted with enough detail and the right legal structure to carry the risk appropriately.

Using A Template That Doesn't Match Your Deal

It's tempting to grab a template online and fill in the blanks. The risk is that Heads of Agreement are heavily dependent on context.

For example, a HoA for a business sale is completely different to a HoA for an ongoing services relationship - and if the drafting doesn't match the transaction, you can get:

• missing essential clauses
• inconsistent terms that cause confusion later
• accidental binding obligations you didn't intend
• commercial terms that aren't enforceable or workable in practice

It's also common for parties to later argue that the Heads of Agreement contains a "mistake" or doesn't reflect what was agreed. If the document is unclear, that argument becomes more likely - and harder to resolve quickly.

Where you're unsure whether your HoA wording might be treated as final or preliminary, it helps to sense-check it against common contract principles (including whether key terms are certain enough to be enforceable).

Key Takeaways

• A Heads of Agreement is a practical way to document the key terms of a deal before the final contract is signed, helping everyone stay aligned.
• A Heads of Agreement can be non-binding, binding, or partly binding - what matters is how it's drafted and whether the parties act like the deal is already in place.
• Businesses often use Heads of Agreement to confirm the commercial terms, speed up legal drafting, manage confidentiality and exclusivity, and allow early work (like due diligence) to begin.
• A well-drafted HoA usually covers core commercial terms (scope, price, timelines, conditions) plus clear "process" clauses like confidentiality, costs, exclusivity, and governing law.
• Common traps include accidentally creating a binding contract, vague good faith obligations, poorly drafted exclusivity, relying on the HoA as a substitute for a full contract, and using templates that don't match your transaction.
