What if my commercial lease prohibits subletting?

If a lease bans subletting absolutely, the tenant cannot grant a commercial sublease without varying the lease or obtaining the landlord’s agreement. Doing so may be a serious breach of lease.

Can a landlord refuse consent to a commercial sublease?

If the lease says consent is required, the landlord must usually act in accordance with the lease and applicable law. In many cases, consent cannot be unreasonably withheld, but this depends on the lease wording and circumstances.

What conditions can a landlord impose on a commercial sublease?

Common conditions include approving the subtenant, approving the sublease terms, requiring the sublease to mirror head lease obligations, obtaining a rent deposit or guarantee, and entering into a licence to underlet.

What is a licence to underlet?

A licence to underlet is a formal document by which the landlord consents to the tenant granting a sublease. It normally records the approved subtenant, premises, rent, term and conditions of consent.

Can I sublet only part of my commercial premises?

It depends on the lease. Subletting part of commercial premises is often more restricted than subletting the whole and may require express permission, plans, landlord approval and compliance with services, access and insurance arrangements.

Who remains liable under the head lease after a commercial sublease is granted?

The tenant normally remains liable to the landlord under the head lease, including for rent and compliance with covenants, even after granting a sublease. The subtenant is separately liable to the tenant under the sublease.

What should a commercial sublease agreement include?

A commercial sublease should include the premises, term, rent, permitted use, repair obligations, insurance, service charge, assignment and further subletting restrictions, break rights, default provisions and required head lease obligations.

Should the commercial sublease include head lease obligations?

Yes. The sublease should be carefully drafted so the subtenant is bound to comply with relevant head lease terms, such as use, alterations, repair, insurance, nuisance and statutory compliance.

What happens if I grant a commercial sublease without consent?

It may be a breach of the head lease. The landlord may be able to take enforcement action, seek forfeiture, claim damages or require the unauthorised sublease to be ended, depending on the lease and circumstances.

Can a short commercial sublease be legally binding without registration?

Yes, if it is documented as a lease, grants exclusive possession for a term at rent and does not exceed seven years. Longer leases generally require registration at HM Land Registry to take legal effect.

Does a commercial sublease need to be registered at the Land Registry?

A commercial sublease for more than seven years must usually be registered at HM Land Registry. Some shorter leases may also require noting or registration depending on the circumstances and title requirements.

Should a commercial sublease be contracted out of the Landlord and Tenant Act 1954?

Usually, yes. Most commercial underleases in England and Wales are contracted out of the Landlord and Tenant Act 1954 so the subtenant does not gain statutory renewal rights, but the correct notice and declaration process must be followed before completion.

Are VAT or SDLT payable on a commercial sublease?

This depends on the nature of the premises, the rent, the term and any option to tax. VAT and Stamp Duty Land Tax may apply, so tax advice should be taken before completing the sublease.

Can a commercial sublease include a break clause?

Yes, but only if the head lease allows it, any required consent is obtained, and the sublease contains appropriate break provisions. The break date must not fall after the head lease expiry.

What information do I need before creating a Commercial Underlease Agreement?

You may need the head lease, title details, landlord consent requirements, agreed commercial terms, premises plan, subtenant details, rent and service charge arrangements, insurance provisions and any licence to underlet requirements.

Are You Granting Out Of An Existing Commercial Lease?

Yes, I am the tenant

No, I own the freehold or head interest

Start by checking whether you are the tenant under an existing commercial lease, rather than an owner granting a lease direct to an occupier. A sublease, often called an underlease, is granted by a tenant out of its existing leasehold interest.

Can You Grant A Commercial Sublease In The United Kingdom?

A commercial sublease can be useful where a tenant has surplus space or wants another business to occupy the premises. However, in the United Kingdom the right to underlet depends mainly on the existing lease, landlord consent, statutory rules and the proposed business use.

Why Is The Headlease The Starting Point?

The headlease controls what the tenant can grant. If the lease prohibits underletting, restricts the term, limits the permitted use or requires a licence to underlet, ignoring those terms may put the tenant in breach. Serious breach can lead to claims, loss of consent rights, or forfeiture action.

Why Does Landlord Consent Matter?

Many UK commercial leases allow subletting only with written landlord consent. In England and Wales, legislation may require a landlord to deal with consent applications reasonably in some circumstances, but tenants should not assume consent is automatic. A properly documented licence to underlet helps prove that the sublease was authorised.

Why Are 1954 Act Rights Important In England And Wales?

Business tenants in England and Wales may have security of tenure under the Landlord and Tenant Act 1954. If the parties want the sublease to be contracted out, the statutory notice and declaration procedure must be completed before the tenant is bound. Getting this wrong can leave the subtenant with renewal rights that the parties did not intend.

What Other Checks Should Be Made Before Granting An Underlease?

Term: the sublease must end within the tenant’s own lease term.
Premises: the tenant can only sublet space included in its lease.
Use: the subtenant’s business must comply with lease restrictions and planning rules.
Consents: landlord, superior landlord, management company or lender approval may be needed.
Tax and registration: SDLT, LBTT, LTT and land registration rules may apply depending on jurisdiction, rent and term.

Making the right decision before drafting a commercial underlease reduces the risk of an invalid arrangement, unexpected statutory rights, tax penalties, registration problems and disputes with the landlord or subtenant.
