Updated April 2026. Reflects the Landlord and Tenant Act 1954 Part II, Landlord and Tenant (Covenants) Act 1995, Law of Property Act 1925 and current HM Land Registry rules on lease registration.
A UK commercial lease is a property right, not a personal permission. Sign one without understanding the security-of-tenure question, the repair covenant or the registration requirement and you can find yourself locked into terms that don’t match the deal you thought you were doing — sometimes for years.
This guide covers what every UK commercial lease should address in 2026, the 1954 Act decision that defines the whole arrangement, and the negotiating points worth pushing on whether you’re the landlord or the tenant.
The 1954 Act: the most important question first
Part II of the Landlord and Tenant Act 1954 gives business tenants in England and Wales a statutory right to renew their lease at the end of the contractual term. This is “security of tenure” — the tenant has the right to a new lease on broadly similar terms unless the landlord can prove one of seven statutory grounds (the “B grounds” for refusing renewal).
The lease can be “contracted out” of Part II via the procedure in section 38A. If contracted out, the tenant has no statutory renewal right — when the lease ends, the lease ends.
The contracting-out procedure is highly prescribed:
- The landlord serves a “warning notice” in the prescribed form before the lease is entered into
- The tenant signs either a simple declaration (if there are at least 14 days between warning notice and lease) or a statutory declaration before an independent solicitor (if less than 14 days)
- The lease itself contains specific contracting-out language referring to the warning notice and declaration
Get this wrong and the lease is inside the 1954 Act regardless of what the parties intended. Tenants get protection they didn’t expect. Landlords lose the option to recover the property. The signed declarations and warning notice should be kept with the lease — they’re proof of the contracting-out.
Practical effect: landlords typically prefer contracted-out leases (no statutory renewal hassle); tenants typically prefer to stay inside the Act (right to renew). Position is negotiable and depends on rent level, location, market.
The other essential clauses
Term
How many years? UK commercial leases typically run 1, 3, 5, 10 or 15 years. Shorter terms suit flexible occupiers; longer terms reduce admin and lock in rent. Anything over 7 years must be registered at HM Land Registry — the lease isn’t fully effective in law until registered.
Rent
The annual rent and payment dates (usually quarterly in advance on the “usual quarter days” — 25 March, 24 June, 29 September, 25 December). VAT — is rent VAT-able? Depends on whether the landlord has elected to tax. If so, the rent is plus 20%.
Rent review
How does the rent change over the term? Common patterns:
- None — fixed throughout the term. Common for short leases.
- Fixed uplift — e.g. 3% per year. Predictable but doesn’t track market.
- RPI/CPI-linked — tracks inflation. Capped and collared by negotiation.
- Open-market upward-only — rent reviewed to market every 5 years, but never goes down. Standard for longer leases. Can be controversial in falling markets.
Repair covenant
Who maintains what? Two main models:
- Full Repairing and Insuring (FRI) — tenant repairs and reimburses insurance. Standard for whole-building lets.
- Internal repair only — tenant maintains the inside, landlord deals with structure and exterior, tenant contributes via service charge. Standard for unit-within-building lets.
Watch out for “yield up in good repair” obligations. At the end of the term, the tenant typically must hand back in the same condition (fair wear and tear excepted, damage by insured risks excepted). This drives dilapidations claims at lease end — the cost of putting the property back into the required condition. For older or quirkier buildings, dilapidations can run to tens of thousands of pounds. A schedule of condition (a survey at the start of the lease) caps the obligation to the original condition rather than absolute repair.
Insurance
Almost always: landlord insures the building, tenant pays insurance rent reimbursing the landlord. The lease should specify the insured risks, the duty to rebuild after damage, and what happens to rent during a period when the property can’t be used due to insured damage (rent suspension).
Alienation (assignment, subletting, sharing)
Can the tenant transfer the lease? Sublet to a third party? Share with a group company? The lease will set out controls — typically requiring landlord consent (which under section 19 of the Landlord and Tenant Act 1927 must not be unreasonably withheld). On assignment, the original tenant often must enter an Authorised Guarantee Agreement (AGA) under the Landlord and Tenant (Covenants) Act 1995, guaranteeing the assignee’s performance.
Break clause
The right to end the lease early — typically only the tenant has a break right, on a specified date, with a specified notice period (usually 6 months). Break clauses are notoriously strict — failure to comply with conditions (usually: paid all rent, vacant possession, no material breach) means the break doesn’t operate and the lease continues. Many tenants have lost their break right by missing a condition.
Forfeiture
The landlord’s right to re-enter the property and end the lease for breach. For non-payment of rent, typically operates 21 days after rent due. For other breaches, requires a section 146 Law of Property Act 1925 notice giving the tenant a chance to remedy. Tenants can apply for relief from forfeiture — courts often grant it on payment of arrears and costs.
Heads of terms vs. lease
Most UK commercial lettings start with non-binding “Heads of Terms” agreed by the parties (or their agents). These set out the headline points: parties, premises, term, rent, rent reviews, contracted out or not, break clause, repair, alienation. The lawyers then draft the formal lease reflecting the heads.
The heads are usually marked “subject to contract” — non-binding until the lease is executed. But poorly-drafted heads with ambiguous language can lead to disputes over what was agreed. Take heads of terms seriously even if they’re non-binding.
Common UK commercial lease mistakes
1. Not understanding contracted-out vs. inside-the-Act. The single biggest issue. Tenants signing contracted-out leases without realising they have no renewal right. Landlords letting inside the Act when they wanted flexibility.
2. No schedule of condition. Without one, the tenant’s repair obligation is to “good repair” — open to dispute and often expensive at lease end. A schedule of condition fixes the baseline.
3. Missing the 7-year registration requirement. Leases over 7 years must be registered at HMLR. Common mistake on 10-year leases — drafted, signed, then forgotten until refinancing.
4. Strict break conditions. “Break only operates if all rent paid up to date and property in good repair.” Breaks are forfeitable on technicalities. Push for fewer conditions.
5. Default to landlord’s standard form. Most landlord templates are heavily landlord-favouring. Push back on rent review (upward-only is increasingly resisted), break conditions, alienation controls.

Frequently asked questions
Should I always insist on contracting out?
Depends which side you’re on. Landlord: usually yes, for flexibility. Tenant: typically prefer inside-the-Act for security. The market position varies — in a tenant’s market, contracting-out is often resisted; in a landlord’s market, it’s standard.
What’s an Authorised Guarantee Agreement (AGA)?
Under the Landlord and Tenant (Covenants) Act 1995, when a tenant assigns a lease, the landlord can require the outgoing tenant to guarantee the incoming tenant’s performance. That guarantee is the AGA. It only covers the period of the immediate assignee — not subsequent assignees.
Can I assign my lease without landlord consent?
Almost never. Most leases require landlord consent to assign. Section 19(1A) of the Landlord and Tenant Act 1927 says consent must not be unreasonably withheld. Some leases also include a list of pre-agreed conditions to make assignment more predictable.
What happens at the end of an inside-the-Act lease?
The tenant can request a new lease (section 26 request) or hold over while the parties negotiate. The landlord can serve a section 25 notice to either offer a new lease or oppose renewal on one of seven statutory grounds (e.g. breach by tenant, intention to redevelop, intention to occupy). If the parties disagree, the County Court determines the new terms.
Should I get a solicitor to review the lease?
For any commercial lease over 3 years or with non-trivial rent, yes. The clauses interact in complex ways and small drafting differences (especially in break clauses, rent review and dilapidations) have large financial consequences. A fixed-fee review (typically £1,000-£3,000) is cheap insurance against a 10-year mistake.
