✅ Preparing Your Commercial Subletting Agreement
1. Before starting: Gather the head lease, the landlord's consent position, premises details, both parties' information, and the agreed rent and deposit
2. While completing: Verify every section against all 49 compliance points
3. Before signing: Check the sublease term ends before the head lease expires, the landlord's written consent is in place, and the Landlord and Tenant Act 1954 position has been decided
⚠️ Key Commercial Subletting Requirements
📋 Legal Status: A commercial subletting agreement (sublease) is granted by an existing tenant — the sublandlord — out of its own lease. The subtenant's rights sit beneath the head lease: if the head lease is forfeited or otherwise comes to an end, the sublease normally falls with it.
⚖️ Key Legislation: Landlord and Tenant Act 1988 (landlord's consent to underletting), Landlord and Tenant Act 1954 Part II (security of tenure), and section 146 of the Law of Property Act 1925 (forfeiture and relief).
🚫 Critical Requirements: The head landlord's written consent where the head lease requires it, a sublease term ending before the head lease term, a permitted use that sits within the head lease user clause, and a clear decision on contracting out of the 1954 Act.
📝 Common Issues: Subletting without a required consent (which can put the head lease at risk of forfeiture), granting a term equal to or longer than the tenant's own term (which operates as an assignment), unclear service charge pass-through, and missed contracting-out formalities.
🔵 Understanding Importance Levels
🔴 Critical: Must have — legally required or essential for enforceability
🟡 Important: Should have — protects your position and prevents disputes
🔵 Recommended: Nice to have — best practice for comprehensive coverage
Head Landlord's Full Legal Name and Address
The head landlord (the freeholder or superior landlord under the head lease) should be identified by full legal name and address in the background section of the sublease. The subtenant's occupation ultimately depends on the head lease, so it matters to know exactly who sits above the tenant for consent and notices.
🔴 Critical
Tenant's (Sublandlord's) Full Legal Name
The intermediate tenant granting the sublease. For companies, the name must match the Companies House registration exactly; for individuals, the full legal name. The tenant must hold the leasehold interest out of which the sublease is granted.
🔴 Critical
Subtenant's Full Legal Name
The occupying business's or individual's full legal name. For companies, this must match Companies House registration; for sole traders, the full legal name as it appears on identity documents. Essential for enforcing covenants and pursuing any breach claims.
🔴 Critical
Addresses and Company Details Verified
Registered office or correspondence addresses for the tenant and subtenant, used for serving notices including break notices. Check company numbers and registered addresses against Companies House records, and confirm the signatories are authorised to bind each party.
🟡 Important
Head Lease Details Recorded
The sublease should record the head lease in its background section: the parties, the head landlord's name, and crucially the date the head lease expires. Everything in the sublease hangs off this document, so the details must be accurate.
🔴 Critical
Sublet Premises Clearly Defined
A precise description of the sublet premises, stating whether the subtenant takes the whole of the tenant's premises or only part (a floor, unit, or defined area). The description must fall within the demise of the head lease — the tenant cannot sublet more than it holds.
🔴 Critical
Plan and Excluded Areas
For a subletting of part, attach a plan showing the sublet premises edged or coloured, and state any excluded areas (such as plant rooms, storage, or areas the tenant retains). A clear plan prevents boundary disputes and is needed if the sublease is registrable.
🟡 Important
Head Lease Terms Incorporated
A statement that the sublease is granted subject to and with the benefit of the head lease, with the head lease terms incorporated by reference insofar as they relate to the sublet premises. The subtenant should be given a copy of the head lease (or at least the relevant parts) before signing.
🔴 Critical
Head Lease Alienation Clause Reviewed
Read the alienation (underletting) clause in the head lease before drafting anything. It will either prohibit underletting absolutely, permit it with the landlord's consent (a qualified covenant), or permit it freely. Subletting in breach of an absolute prohibition puts the head lease at risk of forfeiture.
🔴 Critical
Landlord's Written Consent Obtained
Where the head lease requires consent, obtain the landlord's consent in writing — usually as a licence to sublet or deed of consent — before the sublease is granted. The agreement should record that consent has been obtained, or make the grant conditional on obtaining it.
🔴 Critical
Statutory Duty on Consent Understood
Where the head lease says consent is not to be unreasonably withheld, the Landlord and Tenant Act 1988 places a duty on the landlord to respond to a written application within a reasonable time, to give consent unless it is reasonable to refuse, and to set out any conditions or reasons in writing. Make the application in writing and keep proof.
🟡 Important
Conditions of Consent and Costs
The landlord may attach conditions to its consent (for example, that the sublease is contracted out of the 1954 Act or mirrors the head lease terms). The sublease should record who pays the landlord's and tenant's reasonable costs of the consent — commonly the subtenant pays a fair proportion — and that any conditions will be complied with.
🟡 Important
Commencement Date
A clear start date when the sublease begins and the subtenant can take occupation. Essential for calculating rent payments, break dates, and notice periods. Must be unambiguous — a specific calendar date, not "on completion".
🔴 Critical
Sublease Ends Before Head Lease Expiry
The sublease term must end before the head lease term — build in a reversion of at least a few days. A sublease granted for a term equal to or longer than the tenant's own remaining term takes effect as an assignment of the head lease, not a sublease, with very different consequences.
🔴 Critical
Term Length Clearly Stated
The length of the term (in months or years) from the commencement date, producing a definite expiry date. Cross-check the expiry date against the head lease expiry recorded in the background section — the dates must be consistent.
🔴 Critical
Land Registry Registration If Over 7 Years
A sublease granted for a term of more than seven years must be registered at HM Land Registry with its own title. Shorter subleases generally do not need their own registration. Factor in registration time, fees, and the need for a compliant plan for lettings of part.

Rent Amount and Payment Frequency
A clear statement of the rent (e.g. £1,500 per month) with the annual equivalent, payable monthly or quarterly in advance to the tenant by bank transfer. The subtenant pays the tenant, not the head landlord — the tenant remains responsible for the head lease rent.
🔴 Critical
Payment Due Dates and First Payment
The specific date each period when rent falls due (e.g. the 1st of each month) and the date the first payment is due, with any apportionment for a part period. Important for determining when arrears arise and when forfeiture rights for non-payment are triggered.
🟡 Important
Rent Review Mechanism
Whether rent is fixed for the term, increases by RPI/CPI indexation, or is reviewed to open market value on set dates. On longer subleases, consider aligning review dates with the head lease so the tenant is not left out of pocket between reviews.
🔵 Recommended
VAT and SDLT Position
State whether the tenant has opted to tax, in which case VAT (currently 20%) is added to the rent, and whether sums are exclusive or inclusive of VAT. Separately, Stamp Duty Land Tax can be payable by the subtenant on the grant of a sublease where the net present value of the rent or any premium exceeds the non-residential threshold — a return to HMRC may be required even where no tax is due.
🔴 Critical
Deposit Amount and Terms
The deposit amount (commonly one to three months' rent), what the tenant may deduct (unpaid rent, breach remediation, damage), and the return timetable — typically within 14 days of the end of the term with a statement of deductions. Commercial deposits are not held in a government protection scheme, so the contractual terms govern; the deposit must not be used by the subtenant in lieu of rent.
🟡 Important
Service Charge Pass-Through
How the service charge under the head lease is passed on to the subtenant: a fair proportion attributable to the sublet premises, a fixed percentage, or an inclusive rent with no separate charge. The mechanism should be spelt out so the subtenant can verify what it is being asked to pay.
🔴 Critical
Service Charge Cap or Fixed Amount
Consider a cap or fixed service charge to protect the subtenant against an uncapped pass-through of head lease costs, particularly major works. If uncapped, the subtenant should ask for recent service charge accounts and budgets before committing.
🔵 Recommended
Utilities Responsibility
Who pays for electricity, gas, water, and telecoms: metered separately to the subtenant, apportioned between the parties, or included in the rent. For sublettings of part without separate meters, state the basis of apportionment to avoid disputes.
🟡 Important
Business Rates Responsibility
Who pays business rates on the sublet premises: the subtenant directly to the council, the tenant with reimbursement, or included in the rent. A subletting of part may require a separate rating assessment from the Valuation Office Agency.
🔴 Critical
Repair Standard Defined
State the repair obligation clearly: typically the subtenant keeps the interior of the sublet premises in good repair and condition. The tenant will usually want the obligation to mirror its own repairing covenant in the head lease so it is not left with a gap; the subtenant should resist taking on more than the tenant itself owes.
🔴 Critical
Schedule of Condition (If Used)
A photographic schedule of condition agreed and attached at the start limits the subtenant's repair and yield up obligations to the state of the premises at the commencement date. Particularly worthwhile for older premises or short terms.
🟡 Important
Exclusions and Tenant's Right to Inspect
The subtenant should not be liable for structural repairs, external repairs, or defects inherent in the design or construction of the building. The tenant should reserve the right to enter on reasonable notice to inspect the state of the premises and carry out any repairs required under the head lease.
🟡 Important
Yield Up Obligations
What the subtenant must do at the end of the term: yield up the premises in repair consistent with its covenants, remove all chattels and effects, make good damage caused by removal, and return keys. The agreement should state that no compensation is payable for improvements or goodwill.
🔴 Critical
Permitted Use Within the Head Lease User Clause
The permitted use in the sublease must sit within the user clause in the head lease and the planning use of the building. Define it clearly (e.g. "offices for a design consultancy") and require the premises to be used for that purpose and no other. A use the head lease forbids exposes the tenant to a breach claim.
🔴 Critical
Compliance with Head Lease Covenants
A covenant that the subtenant will observe the tenant covenants in the head lease, as if the subtenant were named as the tenant, insofar as they relate to the sublet premises. Remember the tenant remains fully liable to the head landlord for the whole of the head lease whatever the subtenant does.
🔴 Critical
Alterations Restrictions
The subtenant should not make alterations or additions without the tenant's prior written consent — and bear in mind the head landlord's consent may also be needed under the head lease. Also cover prohibited activities (nuisance, illegal use, anything voiding insurance) and statutory compliance, including health and safety and fire regulations.
🟡 Important
No Further Underletting or Assignment
A covenant that the subtenant will not assign, sub-underlet, charge, or share occupation of the sublet premises without the tenant's prior written consent. Each further layer multiplies the consent requirements and the head lease almost certainly restricts it too.

Insurance Arrangements Identified
State who insures the building — usually the head landlord under the head lease — and how the premium is dealt with in the sublease: included in the head lease arrangements, a proportionate share paid by the subtenant, or separate insurance arranged by the subtenant. The choice should match how the head lease actually works.
🔴 Critical
No Acts That Affect Insurance
A covenant that the subtenant will not do anything that may void or adversely affect any insurance policy maintained by the tenant or the head landlord, and will notify the tenant immediately of any event that might give rise to a claim. A voided buildings policy is a serious head lease breach.
🟡 Important
Subtenant's Own Cover
The subtenant should maintain its own insurance for contents, business interruption, and public liability (commonly £2,000,000 minimum or more). The buildings policy will not cover the subtenant's equipment, stock, or liability to visitors.
🟡 Important
Forfeiture Triggers Stated
The events allowing the tenant to re-enter and end the sublease: rent unpaid for a stated period (commonly 14 days after falling due), breach of covenant, and the subtenant's insolvency or arrangement with creditors. Without an express forfeiture clause the tenant has no right of re-entry.
🔴 Critical
Head Lease Forfeiture Ends the Sublease
The sublease should state that it terminates automatically if the head lease is forfeited, determined, or comes to an end for any reason. This is the subtenant's biggest structural risk: its occupation depends on the tenant keeping the head lease alive, so the subtenant may want comfort that head lease rent is being paid.
🔴 Critical
Relief from Forfeiture Understood
If the head lease is forfeited because of the tenant's breach, the subtenant can apply to the court for relief under section 146(4) of the Law of Property Act 1925, which may allow it to stay — usually on terms such as taking on the head lease obligations. Relief is discretionary, not automatic, so it is a safety net rather than a substitute for due diligence.
🟡 Important
Breach Consequences and Damages
Re-entry by the tenant should be expressed to be without prejudice to accrued rights and remedies, and the tenant should be entitled to damages for breach of covenant. The subtenant should understand that losing the premises does not wipe out liability for arrears or disrepair.
🟡 Important
Contracting-Out Decision Made
Decide whether the sublease will be excluded ("contracted out") from Part II of the Landlord and Tenant Act 1954. A business subtenant in occupation otherwise gains statutory renewal rights at the end of the term. Head landlords commonly make contracting out a condition of their consent to subletting.
🔴 Critical
Warning Notice and Declaration Before Grant
To contract out, the tenant (as sublandlord) must serve the prescribed warning notice on the subtenant BEFORE the sublease is granted, and the subtenant must make a simple declaration — or a statutory declaration if the sublease is granted less than 14 days after the notice. The sublease should then refer to the notice and declaration. Get the sequence wrong and the exclusion fails.
🔴 Critical
Consequences Understood by Both Parties
A protected subtenant may be entitled to remain and seek a new tenancy at the end of the term — potentially directly against the head landlord once the head lease ends. A contracted-out subtenant must leave at expiry with no statutory right to renew or to compensation. Both parties should understand which position applies before signing.
🟡 Important
Tenant's Break Clause (If Included)
If the tenant has a right to end the sublease early, state the earliest break date, the notice period (commonly three to six months), and that notice must be in writing. A tenant facing its own head lease break may need to clear out the subtenant first — the dates should work together.
🟡 Important
Subtenant's Break Clause (If Included)
Any right for the subtenant to end the sublease early, with its own earliest break date and notice period. A break right is valuable flexibility for a subtenant taking space on someone else's lease terms — record it expressly or it does not exist.
🟡 Important
Break Notice Mechanics and Conditions
Break clauses are construed strictly: the notice must be served on the right party, at the right address, by the permitted method, and on time. Any conditions — such as rent paid up to the break date or vacant possession — must be satisfied exactly. Serve in accordance with the notices clause and keep proof of service.
🔴 Critical
Signatures and Witnessing
Signature blocks for the tenant and the subtenant, each signed in the presence of a witness who adds their name, address, and occupation. Subleases granted for more than three years are normally executed as a deed. Both parties should retain a signed copy, along with the landlord's consent and any 1954 Act paperwork.
🔴 Critical
Notices Provisions
How formal notices under the sublease may be served: delivered personally, sent by first class post, or by email with receipt acknowledgment, to the addresses at the head of the agreement or such other address as a party notifies. These mechanics matter most for break notices and forfeiture-related correspondence.
🟡 Important
Governing Law and Boilerplate
The agreement should be governed by the law of England and Wales with the courts of England and Wales having jurisdiction. Include an entire agreement clause, variation only in writing, no set-off against rent, severability, and counterparts. Record any additional agreed provisions in the additional provisions section rather than in side conversations.

📝 Draft Your Own Commercial Subletting Agreement
Use this checklist as your guide, but remember: a sublease sits beneath the head lease. Subletting without a required consent can put the tenant's own lease at risk of forfeiture, and if the head lease ends early the sublease normally falls with it. Check the head lease alienation clause — and the 1954 Act position — before anything else.
