Letter Of Intent Template (UK): What To Include And When You Need One

If you’re negotiating a new deal - buying a business, bringing in an investor, signing a major supplier, or agreeing key commercial terms - you might reach the point where you’re thinking: “We’re aligned… but we’re not ready to sign the full contract yet.”

That’s exactly where a letter of intent (often called an “LOI”) can help.

In this guide, we’ll walk you through what a letter of intent template UK should include, when it’s worth using one, and the common traps to avoid (especially around whether your LOI becomes legally binding when you didn’t mean it to).

What Is A Letter Of Intent (LOI) In The UK?

A letter of intent is a document you use to set out the key terms you and the other party have agreed in principle, before you sign the full formal contract.

In practice, it’s often used as a “bridging document” when:

• you want to show serious commitment (without finalising everything yet);
• there are still details to negotiate; or
• you need to start some steps (like due diligence or reserving a date) while the lawyers draft the main agreement.

LOIs are common in:

• business sale / purchase negotiations;
• commercial leases and property deals;
• supplier or manufacturing relationships;
• investment and fundraising discussions;
• partnership or collaboration projects; and
• contractor or service arrangements (especially high-value ones).

It’s worth noting: a letter of intent is different from a full contract, and it’s also different from a “heads of terms” or “heads of agreement” (though in the real world, these labels are often used interchangeably). If you’re at the stage of locking in key commercial points, a Heads of Agreement can play a similar role - the key is being crystal clear about what is and isn’t binding.

Is A Letter Of Intent Legally Binding In The UK?

This is the big one - and it’s where businesses can accidentally create legal obligations they didn’t expect.

In the UK, a letter of intent can be fully binding, partly binding, or non-binding, depending on:

• how it’s drafted (the language really matters);
• whether the parties intended to create legal relations;
• whether the key elements of a contract are present; and
• what the LOI says about binding vs non-binding clauses.

As a rule of thumb, a well-drafted LOI often does this:

• Non-binding: commercial deal terms (price, scope, timeline) are “subject to contract” and not binding yet.
• Binding: specific protective obligations can be binding now (like confidentiality, exclusivity, cost allocation, and governing law).

If you’re unsure where the line is, it helps to understand what makes a contract legally binding, because many LOI disputes come down to those fundamentals.

Watch Out For “Subject To Contract”

In many UK commercial negotiations, using the phrase “subject to contract” is a key signal that the parties don’t intend to be legally bound until a full contract is signed.

But don’t rely on that phrase alone. Depending on the wording and conduct, there can still be legal arguments about whether a binding agreement was formed (in full or in part) - and in some areas, there are additional enforceability hurdles regardless. For example, land/property transactions generally need to meet strict formality requirements, and vague “agreements to agree” can be difficult to enforce.

Don’t Forget That Emails Can Bind You Too

A practical point: even if your LOI isn’t binding, your email trail might create obligations (or at least create evidence that you intended to be bound). If your negotiation is happening quickly over email, it’s worth keeping in mind whether emails are legally binding in certain situations.

This doesn’t mean you need to panic - it just means it’s smart to tighten up your process, use clear wording, and get the key documents right before money changes hands or work starts.

When Does Your Business Need A Letter Of Intent?

You don’t need a letter of intent for every deal. For many small business arrangements, a properly drafted contract (or even a short agreement) is more straightforward.

But an LOI can be a strong move when you want to progress negotiations without leaving your business exposed.

Common Situations Where An LOI Makes Sense

• You’re buying or selling a business and want to agree headline terms before due diligence and contracts are finalised.
• You’re negotiating exclusivity (for example, you don’t want the other party shopping your deal around while you spend time and money on due diligence).
• You need confidentiality protections before you share sensitive financials, customer lists, or know-how.
• You’re planning a joint project and want to confirm the plan before investing in drafting full legal documents.
• You’re dealing with tight timelines (for example, you need to reserve stock, book a venue, or secure manufacturing capacity).
• You want internal alignment (an LOI can clarify what has been agreed so your team can start planning confidently).

When A Different Document Might Be Better

Sometimes, what you really need is not an LOI but a different early-stage document.

• If you want a broad, non-binding outline of cooperation, a Memorandum of Understanding may fit better.
• If you need immediate protections around sensitive information, you may need an Non-Disclosure Agreement before anything else.
• If you’re already agreed on the commercial deal and just need the full legal terms, it can be quicker to move straight to a proper contract (rather than adding another document to manage).

The “right” approach depends on your bargaining position, risk tolerance, and how far along the negotiations actually are.

What To Include In A Letter Of Intent Template (UK Checklist)

A good letter of intent template UK should be easy to read, commercially clear, and legally careful. You want it to move the deal forward - not create confusion (or disputes) later.

Here’s a practical checklist of clauses and sections most UK businesses should consider.

1) The Parties And The Proposed Transaction

• Full legal names of each party (check Companies House details if relevant).
• Registered address (and company number, where applicable).
• A short description of the proposed transaction (what you’re aiming to do).

2) Deal Terms (Usually Non-Binding)

These are the commercial “headline” terms. Often they are stated as indicative and subject to contract.

• Price or pricing structure (or price range, or valuation method).
• Payment structure (deposit, milestones, completion payment, earn-out, etc.).
• Scope: what’s included and what’s excluded.
• Key deliverables, service levels, or specifications.
• Timing: proposed start date, completion date, target timetable.
• Conditions (for example: board approval, finance, due diligence).

Tip: If you’re still unsure about the commercial terms, it’s better to keep them higher-level than to lock in something inaccurate “just to get it signed”. A letter of intent should support negotiation - not sabotage it.

3) Due Diligence And Information Sharing

If one party is going to spend time reviewing documents (financials, legal agreements, IP, customer metrics), spell out:

• what documents will be provided (and in what format);
• who pays the costs of due diligence;
• the due diligence timetable;
• how questions and responses will be handled; and
• whether any information can be shared with advisors (accountants, lawyers, funders).

4) Confidentiality (Often Binding)

Confidentiality is one of the most common binding parts of an LOI.

You can either:

• include confidentiality terms directly in the LOI; or
• say that a separate NDA applies (and attach it).

Either way, be clear about what “confidential information” means, the permitted uses, and how long confidentiality obligations last.

5) Exclusivity / Non-Solicitation (Often Binding)

If you’re about to invest time and money into the deal, you might want exclusivity so the other side can’t negotiate a competing transaction during a set period.

• Define the exclusivity period (e.g. 30, 60, or 90 days).
• State what is prohibited (e.g. soliciting other offers, engaging in negotiations, providing info to competitors).
• Include carve-outs if needed (e.g. existing discussions disclosed upfront).

Be careful: exclusivity can be commercially sensitive, and if it’s binding it needs to be drafted with real precision - otherwise it can become a dispute magnet.

6) Timetable And Next Steps

This is where a letter of intent can really earn its keep. Set out a realistic roadmap, for example:

• date for completing due diligence;
• date for providing the first draft contract;
• target date for signing;
• target completion date; and
• internal approvals required.

7) Costs

Who pays for what while you’re negotiating?

• Each party pays their own legal and advisory costs; or
• one party pays up to a cap; or
• costs are reimbursed if certain milestones aren’t met (be cautious with this).

8) “Subject To Contract” And Non-Binding Statement

If your goal is to keep the LOI mostly non-binding, you want a clear statement that:

• the letter is not intended to create a binding agreement for the main transaction; and
• the parties will only be bound when formal contracts are signed (and possibly delivered).

This is also a good place to clearly identify which sections are binding (like confidentiality and exclusivity).

9) Termination / Expiry

LOIs shouldn’t hang around forever. Include:

• an expiry date; and/or
• termination triggers (e.g. signing a definitive agreement, one party giving notice, or failure to meet milestones).

10) Governing Law And Jurisdiction (Often Binding)

Even if most of your LOI is non-binding, it’s normal to include a binding clause that says the letter is governed by the laws of England and Wales (or Scotland / Northern Ireland, depending on where you operate) and which courts have jurisdiction.

Letter Of Intent Template UK (Example Draft You Can Adapt)

Every transaction is different, so treat the below as a starting point rather than a one-size-fits-all solution. The safest LOIs are the ones drafted to match your deal, your industry, and your risk profile.

Example Letter Of Intent (UK)

1. Parties

This Letter of Intent (“LOI”) is made between:

• of (Company No. ) (“Party A”); and
• of (Company No. ) (“Party B”).

2. Proposed Transaction

The parties intend to negotiate a definitive agreement under which (the “Transaction”).

3. Headline Commercial Terms (Non-Binding)

• Scope:
• Price:
• Payment terms:
• Key conditions: subject to due diligence, contract, and internal approvals
• Target timetable:

For the avoidance of doubt, this clause 3 is non-binding and is subject to contract.

4. Due Diligence

Party B will provide Party A with reasonable access to information and documents required for due diligence purposes by . Party A will conduct due diligence by .

5. Confidentiality (Binding)

The parties agree to keep confidential all information disclosed in connection with the Transaction, and to use that information solely for the purpose of evaluating and negotiating the Transaction, except where disclosure is required by law or to professional advisers who are bound by confidentiality obligations.

6. Exclusivity (Binding) (Optional)

In consideration of Party A progressing the Transaction, Party B agrees that for a period of days from the date of this LOI, it will not solicit, negotiate, or enter into any agreement with any third party concerning a transaction substantially similar to the Transaction.

7. Costs

Each party will bear its own legal and advisory costs incurred in connection with the Transaction unless otherwise agreed in writing.

8. Non-Binding Nature / Binding Clauses

Except for clauses (which are intended to be legally binding), this LOI is not intended to create a legally binding agreement and no party will be legally bound unless and until a definitive agreement is executed.

9. Governing Law And Jurisdiction (Binding)

This LOI and any dispute arising from it will be governed by the laws of and the courts of will have exclusive jurisdiction.

10. Signed

Signed for and on behalf of Party A: ____________________

Name / Title: ____________________

Date: ____________________

Signed for and on behalf of Party B: ____________________

Name / Title: ____________________

Date: ____________________

Practical note: if you’re executing something as a deed, or you have specific signature requirements (for example, two directors), it’s worth getting advice on proper execution. The process can matter for enforceability, and executing contracts correctly is part of keeping your deal watertight.

Common Mistakes With LOIs (And How To Avoid Them)

A letter of intent can be a helpful commercial tool - but only if it’s drafted with care.

Mistake 1: Using A Generic Template Without Checking What Becomes Binding

Many “free LOI templates” blur the line between non-binding deal terms and binding obligations. That can lead to arguments like:

• “You promised to buy at this price,” or
• “You committed to start work on that date,” or
• “You agreed to exclusivity, so you owe us losses.”

Fix: label what is non-binding, specify what is binding, and use “subject to contract” properly.

Mistake 2: Being Too Vague About The Deal

If your LOI is so vague it doesn’t actually clarify anything, it can become pointless (or worse, it can create confusion that harms the negotiation).

Fix: set out the commercial intent clearly, especially scope, timing, and key conditions - even if the numbers are still indicative.

Mistake 3: Forgetting About Confidentiality And IP

Often, the first thing that happens after an LOI is signed is information-sharing. That might include your pricing model, supplier terms, marketing plan, or product roadmap.

Fix: lock in confidentiality early, and if you’re sharing creative work or software, think about IP ownership and permitted use.

Mistake 4: Starting Work Or Paying Money Before The Right Contract Is Signed

Small businesses often feel pressure to move fast - and that’s understandable. But starting performance before the proper contract is in place can create disputes about scope, payment, and liability.

Fix: if work must start early, consider an interim agreement (or ensure the LOI has clear, binding interim terms that address payment, liability, and termination).

Mistake 5: Assuming The LOI Replaces The Main Contract

An LOI is usually not the final step. It’s a stepping stone.

Fix: include clear next steps and a drafting timeline so everyone knows the LOI is not the endpoint.

Key Takeaways

• A letter of intent is a practical way to document the key terms of a deal before the full contract is finalised, especially in larger or more complex transactions.
• In the UK, a letter of intent can be fully binding, partly binding, or non-binding - it depends on how it’s drafted and what the parties intended.
• Most businesses aim for an LOI where the commercial terms are “subject to contract”, but specific clauses like confidentiality and exclusivity are binding.
• A good letter of intent template UK should cover the parties, the proposed transaction, headline deal terms, due diligence, confidentiality, exclusivity (if needed), costs, expiry/termination, and governing law.
• Be careful with generic templates - unclear wording can accidentally create enforceable obligations or leave you exposed during negotiations.
• If you’re unsure whether your LOI is doing what you think it’s doing, it’s worth getting it reviewed so you’re protected from day one.
