Heads Of Terms For A Commercial Lease: What To Include And Key Risks

If you’re about to take on a new shop, office, warehouse, studio, clinic, or hospitality space, you’ll usually start with a short document before the full lease arrives.

That document is often called “heads of terms”. And while it can feel like a simple summary, getting the heads of terms for your lease right can save your business a lot of time, cost, and stress later.

In this guide, we’ll walk you through what heads of terms are, what to include, where the biggest legal traps are, and how to negotiate from a small business perspective.

What Are Heads Of Terms In A Commercial Lease (And Are They Legally Binding)?

Heads of terms (sometimes called “lease heads of terms”) are a written summary of the main commercial deal points you and the landlord agree in principle before solicitors draft the full lease.

They’re typically prepared by:

• a letting agent,
• the landlord’s team, or
• your broker / advisor (sometimes with your solicitor’s input).

Why Do Heads Of Terms Matter So Much?

Because they set the direction for the entire lease negotiation. If your heads of terms are vague or missing key points, the landlord’s draft lease may lean heavily in the landlord’s favour - and you’ll either have to accept it, pay more legal fees negotiating, or walk away after wasting weeks.

Are Heads Of Terms Legally Binding In The UK?

Usually, heads of terms for a commercial lease are “subject to contract”, meaning they’re intended to be non-binding until the lease is completed.

However, even where heads of terms are “subject to contract”, you can still end up with binding obligations at an early stage through separate documents or what happens in practice. For example:

• Exclusivity or “lock-out” arrangements can be binding if drafted properly (and supported by consideration).
• Payments such as holding deposits, rent deposits, or fees can create practical commitments even where the lease isn’t signed.
• If you start fitting out or trading early under a short agreement, you could be bound by a separate arrangement (like a licence) even if the lease never completes.

If you’re unsure what you’re committing to at an early stage, it’s worth getting advice before you spend money on surveys, fit-out, and professional fees. A Commercial Lease Review can help you spot the “hidden” obligations that often don’t show up clearly in the heads of terms.

What To Include In Heads Of Terms For A Commercial Lease

A solid set of heads of terms isn’t just “rent and term”. For a small business, the details determine your real cost base, your flexibility if you need to pivot, and your exposure if things don’t go to plan.

Below is a practical checklist of the key points you usually want covered.

1) Parties And The Premises

• Landlord and tenant details (including the legal entity you’re leasing through).
• Premises description (address, suite/unit number, floor, parking bays, storage, outside seating, loading areas).
• What’s included (fixtures, furniture, signage rights, plant and machinery, air conditioning, extraction, etc.).

2) Lease Term, Start Date, And Any Rent-Free Period

• Length of term (e.g. 3 years, 5 years, 10 years).
• Lease commencement date (and whether it depends on conditions like fit-out completion).
• Rent-free period (often requested to help with fit-out costs or to cover the period before trading starts).

3) Rent, Rent Payments, And VAT

• Annual rent and how it’s paid (monthly/quarterly, in advance).
• VAT position (some commercial rents are subject to VAT if the landlord has opted to tax).
• Any stepped rent (e.g. lower rent for the first 6–12 months).

Small business tip: always sanity-check the “headline rent” against the total occupancy cost (service charge, insurance, business rates, utilities, repairs, compliance works, and fit-out). This is general information only (not tax, accounting, or financial advice), so it’s worth getting professional advice on your specific numbers.

4) Rent Review

Rent review clauses can have a big long-term impact. Your heads of terms should cover:

• When reviews happen (e.g. every 3 or 5 years).
• Method (open market, index-linked, fixed increase).
• Whether it’s “upward-only” (very common, but worth understanding).

5) Break Clauses (Your Exit Option)

A break clause can be one of the most valuable protections for a growing business, especially if you’re testing a new location or concept.

Heads of terms should specify:

• Whether there is a break right (tenant break, landlord break, or both).
• When it can be exercised (e.g. at year 3).
• Conditions (common conditions include notice periods, giving vacant possession, and paying all sums due).

6) Repairing And Decorating Obligations

This is a classic area where small businesses get caught out. You might think you’re taking “a unit as-is”, but the lease can make you responsible for expensive repairs.

Heads of terms should cover:

• Repairing basis (full repairing and insuring (FRI), internal only, or limited by schedule of condition).
• Any schedule of condition (photos and written condition record to cap your repairing liability).
• Decoration obligations (including whether you must redecorate at the end of the term).

7) Service Charge, Insurance Rent, And Utilities

• Service charge (estimate, what it covers, and any caps).
• Insurance (who insures, what risks, and whether you reimburse via “insurance rent”).
• Utilities (separately metered, recharge arrangements, communal areas).

If you’re taking space in a larger building, ask for transparency: budgets, historic service charge accounts, and confirmation of any major works planned.

8) Permitted Use And Compliance Requirements

Your heads of terms should clearly state your permitted use - what you’re allowed to do from the premises.

This matters because:

• your use must fit within planning controls,
• your use must match what your business actually does (including ancillary uses), and
• breaching the user clause can lead to enforcement action or even forfeiture risks under the lease.

If your business could evolve (e.g. adding takeaway, retail sales, classes, private events), build flexibility into permitted use wording early.

9) Fit-Out, Alterations, And Signage

If you need to do works before opening, your heads of terms should cover:

• Whether alterations are allowed (and whether landlord consent is required).
• Who approves plans and how long consent will take.
• Signage rights (shopfront signs, fascia signage, window decals, totems, A-boards).
• Reinstatement (whether you must remove fit-out and return to shell at the end).

10) Security: Rent Deposit, Personal Guarantee, Or Other Protections

Landlords often want security from small businesses, particularly startups or new companies.

Heads of terms should set out:

• Rent deposit amount and release conditions.
• Whether a personal guarantee is required (and by whom).
• Whether a guarantor is also guaranteeing other obligations (not just rent).

For many SMEs, this is where the real risk sits. It’s worth understanding rent deposits and guarantees early so you’re not negotiating under time pressure later. Issues like deposit release triggers and deductions can be negotiated, and they’re often covered alongside commercial lease deposit arrangements.

11) Assignment, Subletting, And Sharing Occupation

If you might want to sell the business, restructure, bring in a partner, or reduce costs by sharing space, you’ll want to think about “alienation” provisions.

Heads of terms can cover whether you can:

• assign the lease (transfer it to a new tenant),
• sublet (lease part or all to someone else), or
• share occupation (group companies, franchise models, concession arrangements).

Key Legal Risks With Heads Of Terms Lease Negotiations (And How To Avoid Them)

Heads of terms are meant to make the lease process smoother, but they can also lock you into a “bad deal shape” early if you’re not careful.

Risk 1: You Agree The “Commercial” Points But Miss The Real Legal Cost Drivers

Common examples include:

• an FRI repairing obligation that could cost you tens of thousands at the end of the lease,
• service charges with no caps (including major works),
• rent review wording that allows increases faster than your revenue can keep up, and
• tight alteration restrictions that stop you fitting out properly.

Fix: use heads of terms to capture the risk points clearly (repairing basis, schedule of condition, service charge cap, alterations and signage rights), not just the rent and term.

Risk 2: Break Clauses That Don’t Work In Practice

A tenant break clause can look great on paper, but it’s often conditional. If those conditions are hard to meet, the break may fail - and you’re stuck with the remaining term.

Fix: make sure the heads of terms specify a clean break clause (or at least narrow the conditions). Also build in enough time to serve notice without missing the deadline.

Risk 3: You Start Early Without The Right Document

Sometimes you need access before the lease completes (to measure up, fit out, or even trade). If you do this informally, you can end up in a messy legal position if the lease negotiations fall over.

Fix: if early access is needed, get it documented properly. Depending on the situation, you might use a short-term access licence or other arrangement rather than taking possession informally. In some cases, a licence to occupy may be appropriate while the lease is being finalised.

Risk 4: You Commit To Paying Costs Without Knowing The “Exit” Position

Heads of terms often cover who pays legal fees and other costs. Many landlords ask you to pay their legal costs (or at least their costs if you pull out).

Fix: be clear on:

• who pays whose legal fees,
• whether you must pay costs even if the lease doesn’t complete, and
• any cost caps and when fees are payable.

Risk 5: Your Business Structure Creates Extra Exposure

If you’re signing the lease personally, or giving a personal guarantee, your personal assets could be on the line if the business can’t pay.

Fix: consider whether the tenant should be a limited company, and if so, what the landlord will require as security. If a guarantee is unavoidable, negotiate the scope and duration carefully.

A Practical Step-By-Step Process For Agreeing Lease Heads Of Terms

If you want heads of terms that genuinely protect your business (not just the landlord), it helps to run a simple process.

Step 1: Get Clear On Your Non-Negotiables

Before you go back and forth on drafting, decide what matters most for your business, such as:

• maximum all-in monthly cost,
• minimum fit-out period / rent-free,
• break clause by a specific date,
• use clause flexibility,
• ability to assign if you sell the business.

Step 2: Ask The Right Due Diligence Questions Early

Even before the full lease lands, ask for:

• service charge budget and last 2–3 years’ accounts (if available),
• planned works and whether you’ll be charged,
• energy performance certificate (EPC) rating and any upcoming compliance works,
• confirmation of planning use class / permitted use alignment,
• draft lease (if the landlord already has one).

Step 3: Make The Heads Of Terms Specific (Not “To Be Agreed”)

It’s normal for some items to be “TBC”, but if too much is left open, you lose negotiating leverage once solicitors are instructed.

Try to pin down:

• repairing obligations and schedule of condition,
• service charge inclusions and caps,
• break clause conditions,
• alterations and signage rights, and
• security package (deposit/guarantee terms).

Step 4: Have A Lawyer Review Before You Spend Big Money

It’s common to spend on surveys, fit-out design, and professional fees once heads of terms are agreed. That’s exactly why it’s smart to sense-check the legal risks upfront.

If you’re negotiating a shop lease or consumer-facing site, a Retail Lease Review can be particularly useful because these leases often include extra restrictions around opening hours, signage, and trading requirements.

Step 5: Make Sure Signing And Completion Are Done Properly

Once the final lease is ready, execution mistakes can still cause problems, especially if the lease needs to be executed as a deed.

It’s worth checking the mechanics of signing, including legal signature requirements and whether you need witnesses in place (and who qualifies under who can witness a signature).

When Should You Consider Alternatives To A Full Commercial Lease?

A full commercial lease isn’t always the best fit for a small business - especially if you’re testing demand, launching in a new city, or working with a short-term concept.

Depending on your goals, you might consider:

• a shorter-term licence for flexibility (common in serviced spaces or pop-up style arrangements),
• a lease with a strong break clause rather than a long commitment, or
• negotiating occupation terms where a formal lease isn’t yet in place (this can be risky, so get advice early).

If you’re already occupying a space informally (or you’re being asked to start trading before paperwork is finalised), it’s important to understand the risks - including the potential rights and exposure that can arise without a lease.

Key Takeaways

• Heads of terms are the “blueprint” for your lease, so well-drafted heads of terms can reduce legal costs and prevent nasty surprises later.
• Don’t focus only on rent and term - make sure heads of terms cover break clauses, repairing obligations, service charges, rent review, fit-out rights, and permitted use.
• Key risk areas for small businesses include personal guarantees, rent deposits, “FRI” repair obligations, uncapped service charges, and break clauses that are hard to exercise.
• If you need early access before the lease completes, document it properly (for example, via a licence arrangement) rather than moving in informally.
• Before you spend money on surveys, fit-out, or professional fees, it’s worth getting a legal review of the deal structure so you’re protected from day one.
• When it’s time to sign, make sure the execution formalities are done correctly - especially if the lease is to be executed as a deed and needs witnessing.
