Understanding commercial lease obligations
Key obligations and protections in commercial leases. Covers lease types (FRI, IRI, EFRI), Landlord and Tenant Act 1954 security of tenure, rent reviews, break clauses, alienation provisions, service charges, dilapidations, and Land Registry registration.
Commercial leases govern the relationship between landlords and business tenants for shops, offices, warehouses, restaurants, and other commercial premises. Understanding your lease obligations is essential to avoid costly disputes, unexpected liabilities, and potential loss of business premises.
Key areas covered in this guide:
- Lease types: FRI, IRI, and EFRI structures and who bears repair risk
- Security of tenure: Your right to renew under the Landlord and Tenant Act 1954
- Rent reviews: How rent changes during the lease term
- Break clauses: Terminating early and common pitfalls
- Alienation: Assigning, subletting, and guarantees
- Service charges: What you pay beyond rent
- Dilapidations: Your repair liabilities at lease end
- Registration: Land Registry requirements for leases over 7 years
Before signing any commercial lease: Always seek legal advice from a solicitor experienced in commercial property. Lease terms are negotiable, and early professional input can save significant costs and disputes later.
Commercial lease types
The type of lease determines who bears responsibility for repairs, insurance, and building maintenance. Understanding this allocation is critical to assessing total occupancy costs and risk.
Choosing the right lease type
For tenants:
- FRI leases carry the highest risk - you could face unexpected structural repair bills. Always insist on a Schedule of Condition to limit liability to the property's condition at lease start.
- IRI leases offer more predictable costs through service charges, but review the service charge provisions carefully to avoid uncapped or poorly defined charges.
- EFRI leases combine landlord management with tenant payment - check what services are included and whether the service charge is capped.
For landlords:
- FRI leases transfer maintenance risk to tenants but may be harder to let to smaller businesses
- IRI and EFRI leases allow better control over building management and appearance
Security of tenure - your right to renew
The Landlord and Tenant Act 1954 provides business tenants with statutory protection, giving you the right to remain in premises and renew your lease when it would otherwise end.
Contracting out - what it means for you
If your lease is "contracted out" of the 1954 Act:
- You have NO automatic right to renew at lease end
- The landlord can require you to vacate on the contractual expiry date
- You cannot claim compensation if refused renewal
- Consider whether the lease term gives sufficient certainty for your business investment
Common scenarios for contracted-out leases:
- Short-term leases (under 3 years) where landlord wants flexibility
- Development sites where landlord plans future demolition or redevelopment
- Pop-up or temporary retail units
- Serviced offices and flexible workspace arrangements
Before agreeing to contract out: Understand what you are giving up. For long-term businesses investing in fit-out and building customer relationships, loss of security of tenure is a significant concession that should be reflected in other lease terms (rent, incentives, break rights).
Rent review clauses
Most commercial leases include rent review provisions allowing rent to change during the lease term. Understanding the review mechanism is essential for budgeting and negotiation.
2025 legislative change - upwards-only rent review ban proposed
The English Devolution and Community Empowerment Bill (introduced July 2025) proposes to ban upwards-only rent reviews in new commercial leases in England and Wales. If enacted:
- New leases will not be able to include clauses preventing rent from decreasing
- Rent reviews must allow for both upward and downward adjustment
- Fixed or stepped rent increases agreed at lease commencement remain permitted
- Existing leases with upwards-only clauses will NOT be affected
What this means for tenants: If market rents fall, you will be able to benefit from reduced rent at review. This gives greater protection against being locked into above-market rents during economic downturns.
What this means for landlords: Investment valuations may need adjustment as rent income becomes less predictable. Consider alternative structures (fixed increases, index-linked) that provide income certainty.
Status: The bill is before Parliament. Monitor progress before entering into new leases if the review mechanism is important to your decision.
Turnover rent for retail tenants
Retail businesses may be offered turnover rent arrangements, particularly in shopping centres, airports, or railway stations. Rent is calculated as a percentage of your sales revenue.
How it works
Hybrid model (most common): Base rent + percentage of turnover above threshold
Example: £50,000 per annum base rent + 10% of annual turnover exceeding £1,000,000
If your turnover is £1,200,000, you pay: £50,000 + (10% × £200,000) = £70,000 total rent
Advantages
- Lower fixed costs in difficult trading periods
- Rent aligned with business performance
- Easier to manage cashflow during downturns
Disadvantages
- Must disclose sales figures to landlord (commercially sensitive information)
- Landlord may require regular reporting and audit rights
- Successful businesses pay substantially more than fixed rent
- Complicated calculations for multi-channel retailers (online vs in-store sales)
Negotiation points: Define exactly what counts as "turnover" (exclude VAT? include online sales fulfilled from store? staff purchases?). Agree turnover reporting frequency and audit provisions.
Break clauses - terminating early
A break clause allows you to end the lease before the contractual expiry date. Getting the break right is critical - minor failures can invalidate the break entirely.
How to exercise a break clause successfully
Step 1: Read the lease carefully
- Identify the break date(s) - can you break at any time or only on specific dates?
- Check the notice period - how many months' notice must you give?
- Note the conditions precedent - what must be true on the break date?
- Check service requirements - how must notice be served (post, personal delivery, email)?
Step 2: Serve notice correctly
- Use the exact wording required by the lease
- Address to the correct landlord entity (not an agent or management company unless specified)
- Serve at the correct address (registered office, notice address in lease)
- Use the correct service method (registered post, recorded delivery, personal service)
- Allow time for delivery - notice must ARRIVE within the notice period
Step 3: Satisfy conditions precedent
- Vacant possession: Strip out completely - all furniture, fixtures, signage, stock
- Rent paid up: Clear all rent, service charge, and insurance rent to the break date
- No breaches: Remedy any outstanding lease breaches
- Reinstatement: Remove alterations if required by the lease
Get legal advice: The cost of professional advice is minimal compared to the liability of an invalid break. Have your solicitor review the notice before service.
Alienation - assignment and subletting
Alienation provisions determine whether and how you can transfer your lease to another business or sublet part of your premises.
Authorised Guarantee Agreements (AGAs) explained
If you assign your lease (transfer it to a new tenant), the landlord will usually require you to enter into an AGA. This means:
- You guarantee the new tenant (assignee) will comply with all lease terms
- If the assignee defaults on rent or breaches covenants, the landlord can pursue you
- Your liability continues until the assignee either completes the lease term OR assigns to another party (who also provides an AGA)
Limiting AGA risk:
- Conduct thorough due diligence on your proposed assignee - check their financial standing
- Request a rent deposit from the assignee as additional security
- Negotiate caps or time limits on your AGA liability if possible
- Consider taking an indemnity from the assignee
Pre-1996 leases: If your lease was granted before 1 January 1996, even stricter "privity of contract" rules apply. You could remain liable for the entire remaining lease term even after assignment. Take specialist legal advice before assigning older leases.
Service charges
In multi-let buildings, tenants contribute to building running costs through service charges. Understanding what you pay for - and challenging unreasonable charges - is essential.
Challenging service charges
RICS Professional Statement: The RICS Service Charges in Commercial Property code (1st edition, January 2022) sets best practice standards. While not legally binding, courts and tribunals will consider whether landlords have followed the code.
Key tenant protections:
- Transparency: Landlords should provide budgets before the service charge year and certified accounts after
- Reasonableness: Charges must be reasonable - challenge excessive management fees or inflated contractor costs
- Audit rights: Most leases allow tenants to inspect invoices and supporting documents
- Consultation: For major works, landlords may need to consult tenants before incurring costs
Reserve and sinking funds: Check whether your lease requires contributions to reserve funds. These are held for future works (redecoration, plant replacement) and are NOT refundable when you leave. Factor this into your total occupancy cost.
Dilapidations - your repair liabilities
At lease end, landlords often claim for "dilapidations" - the cost of returning premises to their required condition. Claims can reach tens or hundreds of thousands of pounds.
Protecting yourself from dilapidations claims
At lease start:
- Schedule of Condition: For FRI leases especially, insist on a photographic and written record of the property's condition when you take the lease. This limits your liability to returning the property in no worse condition.
- Review repair obligations: Understand exactly what you are responsible for - internal only, or structure and exterior too?
- Budget for repairs: Set aside funds for ongoing maintenance and end-of-lease liabilities
During the lease:
- Maintain the property to the required standard - deferred maintenance accumulates into larger claims
- Keep records of repairs and maintenance carried out
- Respond promptly to interim dilapidations schedules from the landlord
At lease end:
- Commission your own dilapidations assessment before the landlord's surveyor visits
- Consider carrying out works yourself (usually cheaper than paying the landlord's claim)
- Challenge the landlord's schedule - many items may be disputed or overvalued
- Invoke Section 18(1) if the landlord plans to demolish, redevelop, or substantially alter - your liability may be capped or eliminated
The Dilapidations Protocol: Courts expect both parties to follow the Protocol's timescales and procedures. Landlords should serve schedules within 56 days of lease end; tenants should respond within 56 days. Non-compliance can result in costs penalties.
Land Registry registration
Leases granted for more than 7 years must be registered with HM Land Registry. Failure to register has serious consequences.
Registration process
Who is responsible: The tenant (usually through their solicitor) must apply for registration within 2 months of lease completion.
What happens if you don't register:
- Your lease is recognised only as an "equitable" interest, not a full "legal" interest
- Less protection if the property is sold - a new owner may not be bound by your lease
- Complications when assigning or subletting - assignees will struggle to register their interest
- Late registration may not be possible - you might need the landlord to grant a new lease
Leases of 7 years or less: No registration required, but you should still ensure the lease is properly documented and keep the original safely.
Business rates
In addition to rent, you will be liable for business rates on your commercial premises. Understanding who pays and what reliefs are available can significantly affect your occupancy costs.
Small Business Rate Relief - up to 100% reduction
If your property has a rateable value under £15,000 and you occupy only one property, you may qualify for Small Business Rate Relief in England:
- Rateable value £12,000 or less: 100% relief (no business rates payable)
- Rateable value £12,001-£15,000: Tapered relief on a sliding scale
- Rateable value £15,001-£51,000: Reduced small business multiplier (49.9p vs 55.5p per £1)
Eligibility requirements:
- You must occupy only one property, OR
- Your additional properties each have rateable values under £2,900
How to claim: Apply to your local council (billing authority). Relief is not automatic - you must apply and may need to re-apply annually.
Scotland, Wales, Northern Ireland: Different relief schemes apply. Check with your local authority.
-
Instruct a commercial property solicitor
Do not rely on your landlord's solicitor or use a residential conveyancer. Budget £1,500-£5,000 for legal fees.
-
Commission a building survey
Independent surveyor report on property condition, especially for FRI leases. Identifies defects that could become your liability. Cost: £500-£2,000.
-
Negotiate a Schedule of Condition
For FRI leases, insist on photographic Schedule of Condition appended to lease. Limits your dilapidations liability to deterioration beyond documented condition.
-
Review the service charge schedule
Request 3 years' service charge budgets and certificates. Check what's included/excluded. Negotiate caps on increases if possible.
-
Check planning permission and permitted use
Verify the property has planning permission for your intended use. Confirm the lease's "permitted use" clause allows your business activity.
-
Request rent-free period
Negotiate rent-free period for fit-out works (typically 3-6 months). You'll still pay service charge and business rates during rent-free period.
-
Negotiate break clauses
Push for tenant-only break clause at 3rd and/or 5th year. Ensure conditions are achievable (avoid onerous vacant possession requirements).
-
Consider contracting out implications
If landlord insists on excluding LTA 1954 security of tenure, negotiate longer initial term or more frequent breaks.
-
Budget for all occupancy costs
Rent + service charge + business rates + insurance + utilities + fit-out costs. Add 20% contingency for unexpected costs.
-
Check business rates relief eligibility
Use your local authority's online calculator to estimate rates and check small business relief eligibility before signing.
-
Diary key dates throughout the lease
Set reminders for rent review dates, break clause notice deadlines, lease expiry, and business rates revaluation dates (next: 1 April 2026).
-
Plan for lease end 12-18 months in advance
Decide whether to renew, relocate, or exercise a break. Commission early dilapidations advice. Begin reinstatement works in good time to achieve vacant possession.
-
Register leases over 7 years
Ensure your solicitor applies for Land Registry registration within 2 months of completion. Failure to register creates legal uncertainty and complications.
