If you run a business from a listed building or a property in a conservation area, you have probably already discovered that standard commercial leases do not always fit. Over the years, I have watched countless small-business owners sign leases for heritage spaces only to realise later that the fine print on repairs, alterations, and energy rules works very differently than it does for a modern office block. The gap between what a landlord expects and what a heritage designation actually requires can be surprisingly wide — and expensive to close after the fact.
Heritage leases are not a separate legal category — they are standard commercial leases that sit on top of additional protections and restrictions. The building itself might be Grade I, Grade II*, or Grade II listed, or it could sit within a conservation area. Either way, the lease needs to reflect that the usual freedom to alter, upgrade, or even repaint is heavily constrained. And with a wave of regulatory changes arriving in 2026 — from new EPC requirements to a proposed ban on upwards-only rent reviews — the timing matters more than ever. Here is what you actually need to know.
What a heritage lease actually covers
The most important thing to understand is that a heritage lease does not give you a free pass on building regulations. If anything, it layers extra obligations on top. The lease itself will typically be a standard commercial lease — often on full repairing and insuring terms — but the physical reality of the building means those repair obligations cost more to fulfil. Replacing a single sash window with a modern double-glazed unit is not an option if the building is listed. You need a specialist joiner, timber that matches the original profile, and often listed building consent before work starts.
I have seen tenants assume that because their lease says “the tenant may make non-structural alterations with landlord’s consent,” they can install modern lighting or run data cables through original plasterwork. That is not how it works. The landlord’s consent is one hurdle; listed building consent is another, and the local authority can refuse it even if the landlord agrees. My advice is always to check the building’s listing grade and any existing conservation area restrictions before you sign anything. A good commercial property solicitor who understands heritage constraints is worth the fee.
Why the 2026 reforms hit heritage tenants hardest
Several changes coming in 2026 will affect heritage commercial properties more than modern ones. The first is the proposed inclusion of listed and heritage buildings within EPC and MEES requirements. Currently, many heritage buildings are exempt from minimum energy standards because compliance would unacceptably alter their character. The government’s consultation on reforming the Energy Performance of Buildings framework suggests that exemption may narrow. If your heritage lease does not already address who pays for energy upgrades — and what happens if those upgrades are refused on conservation grounds — you could face a difficult negotiation.
Consider a small retail tenant in a Grade II listed shopfront. Under the current rules, the landlord has no obligation to improve the EPC rating because the building is listed. If the rules change, the landlord might need to install secondary glazing, improve insulation in the roof, or upgrade the heating system — all of which require listed building consent and specialist contractors. The cost could easily run into five figures. Who bears that cost depends entirely on what your lease says about improvements and compliance with future legislation.
Then there is the proposed ban on upwards-only rent reviews. The English Devolution and Community Empowerment Bill, which has completed its first reading in Parliament, would prohibit upwards-only rent review clauses in new commercial leases and lease renewals. For heritage properties, where the cost of compliance and repair is already higher, the ability for rent to fall in line with market conditions could provide meaningful relief. But it also means landlords may try to set a higher initial rent to compensate for the loss of guaranteed uplifts. The balance of negotiating power is shifting, and tenants need to understand the new landscape.
Where tenants and landlords get tripped up
The most common mistake I see is treating a heritage lease like any other commercial lease. The repair clause, the alteration clause, and the service charge provisions all need bespoke attention. Here are the specific areas where things go wrong.
Underestimating the cost of like-for-like repairs
A standard FRI lease requires the tenant to keep the property in good repair. For a modern building, that means standard materials and standard labour. For a heritage building, it means matching original materials — which may no longer be manufactured — and hiring specialists who charge a premium. The service charge budget for a heritage property can be 30–50% higher than for a comparable modern space, and tenants rarely budget for that.
Assuming energy exemptions will last forever
Many heritage tenants assume they will never need to worry about EPC ratings or MEES compliance. The 2026 reforms suggest otherwise. If your lease does not include a clause requiring the landlord to comply with future energy legislation — or at least to cooperate with reasonable upgrade works — you could end up in a position where you cannot legally let the property and the landlord has no obligation to fix it.
Ignoring the service charge code update
The updated RICS Professional Standard on service charges in commercial property took effect on 31 December 2025. It is compulsory for RICS-accredited professionals and sets new benchmarks for transparency and best practice. For heritage properties, where service charges can be opaque and unpredictable, this code gives tenants stronger grounds to challenge unreasonable charges. If your landlord or managing agent is not following the new standard, you have leverage you may not realise.
| Reform | Effective date | Impact on heritage leases |
|---|---|---|
| EPC reform (shorter validity, heritage inclusion) | Second half of 2026 | May require energy upgrades with conservation consent |
| Business rates revaluation | 1 April 2026 | Rateable values reset; check threshold for lower multiplier |
| Ban on upwards-only rent reviews | Late 2026/2027 (proposed) | Applies to new leases and renewals only |
| RICS service charge code (2nd edition) | 31 December 2025 | Stronger transparency requirements for service charges |
Overlooking the Assets of Community Value changes
The same Devolution Bill that targets rent reviews also proposes widening the definition of Assets of Community Value to include properties that contribute to a local community’s economic wellbeing. If your heritage commercial space is a pub, local shop, or similar community asset, the new rules could give community groups a preferred buyer status and the right to delay a sale for up to 18 months. That affects lease negotiations, particularly if you are considering a break clause or assignment.

Get a specialist survey before you sign
A standard building survey will not cut it for a heritage property. You need a surveyor who understands historic building materials, conservation area restrictions, and the likely cost of compliance with future energy regulations. The survey should identify any existing disrepair, the condition of original features, and the feasibility of potential energy upgrades. Without this, you are negotiating blind on the repair clause.
Negotiate a capped repair obligation
If the lease is on full repairing and insuring terms, push for a cap on the tenant’s repair liability for the first three to five years. This protects you from being held responsible for pre-existing defects that the survey may have missed. Some landlords will agree to a schedule of condition — a photographic and written record of the property’s state at lease commencement — which limits your repair obligation to maintaining that condition rather than improving it.
Address future energy compliance in the lease
Include a clause that sets out who pays for any energy upgrade works required by future legislation, and what happens if listed building consent for those works is refused. Without this, you could face a situation where the law demands an EPC rating you cannot achieve, and the lease does not allow you to break or assign. A tenant landlord lawyer who specialises in commercial property can draft this clause to protect your position.
Plan for the rent review ban
If you are negotiating a new lease or renewal, assume that upwards-only rent reviews will be banned by the time your first review comes around. That changes the economics of the deal. Landlords may ask for a higher starting rent or a shorter rent-free period to compensate. Run the numbers both ways — with and without the ban — so you know what you are actually agreeing to.
Check the service charge budget against the new RICS code
Ask the landlord or managing agent to confirm that the service charge budget for the heritage property complies with the updated RICS Professional Standard. Request a breakdown of planned works, including any conservation-related costs. If the budget seems high, you have the right to challenge it under the new code. A long-term lease on a heritage property needs a service charge mechanism that is transparent and predictable.

The heritage lease landscape is shifting faster than many tenants realise. The 2026 reforms — on energy, rates, rent reviews, and service charges — will change the economics of occupying a historic commercial space. My advice is to treat the lease negotiation as a partnership with your solicitor and surveyor, not a transaction you can handle with a template.
