Who maintains a shop's air conditioning is usually decided by the lease, not by a universal statute that says the landlord always does it. A full repairing and insuring lease often puts the kit on the tenant. A landlord system on a service charge often stays with the landlord or the agent. F-gas operator duties follow whoever has actual control, which may or may not be the person who owns the metal. Read the demise, the plant schedule and the service-charge clause. If they are silent or they clash, a solicitor should read them. This page is practical orientation, not legal advice.
Demise, repairing clause and service charge
The demise says whether the cassette and the outdoor unit are inside the tenant's responsibility. The repairing clause says who fixes them. The service-charge schedule says whether a central plant or a maintenance contract is recovered from tenants. Those three documents can point at different people unless you read them together. A verbal assurance from the letting agent at viewing does not beat the lease. When you take the shop, ask for the plant list and the last service sheet. A missing outdoor unit on the schedule is how a condenser on the roof becomes nobody's job. Lease wording beats assumption. FRI leases often put repair on the tenant. There is no single rule that puts every cassette on the landlord. The lease usually decides repair and cost. Have the lease read if it is unclear.
Operator status beside the repairing clause
Even a clear repairing clause can leave operator status muddy. The operator is the party with actual power over technical functioning. If the tenant calls the engineer and sets the controls, the tenant may carry the F-gas duties, including records and any leak checks that the carbon-dioxide equivalent requires. If only the landlord's contractor may touch the plant, the landlord is the more likely operator. Check current GOV.UK guidance rather than a clause copied from an old licence. Certification rules describe who may do the work. They do not automatically invoice the landlord. Paying a service charge does not automatically make the landlord the operator. Paying toward a contract is not the same as having control of the equipment. Look at who may instruct repairs and at the current GOV.UK definition of operator. Service charges can pay a contract without clarifying F-gas control. Ask a solicitor where the clauses conflict.
Frequently asked questions
Does UK law say the landlord must service shop air conditioning?
There is no single rule that puts every cassette on the landlord. The lease usually decides repair and cost. F-gas operator duties follow actual control. Have the lease read if it is unclear.
We pay a service charge. Does that make the landlord the operator?
Not automatically. Paying toward a contract is not the same as having control of the equipment. Look at who may instruct repairs and at the current GOV.UK definition of operator.
Who arranges an air conditioning inspection?
Whoever the regulations and the lease together make responsible. GOV.UK publishes when an inspection is required. Put the name of the instructing party in the lease schedule if it is missing.
Who looks after staff comfort if the plant is the landlord's?
HSE temperature duties toward staff sit with the employer in the shop, which is often the tenant, even when the landlord owns the plant. If the landlord's system is out of action through summer, the tenant still has a staff-comfort problem and a contractual problem. They are not the same claim. Washing filters and clearing drains are maintenance. The air conditioning inspection described on GOV.UK is a separate duty for systems over a published rated output.
What should be agreed at the start of a lease?
Agree who instructs service, who holds the log, who pays for refrigerant recovery at end of fit-out, and whether the tenant may replace the unit. As a 2026 illustration, an annual contract for a small shop system is often in the low hundreds of pounds including VAT per year for a basic visit pattern, before repairs. Who pays that sum should be one sentence in the heads of terms.
What if the lease is already in dispute?
Stop guessing from blogs and take the lease to a solicitor. Keep servicing the plant in the meantime if you are the party in control, so a regulatory duty is not ignored while the contract argument runs.
