Commercial Landlord Insurance: The UK Guide for 2026

Who insures a commercial building: the FRI lease

Most UK commercial property is let on a full repairing and insuring lease, usually shortened to FRI. Under the classic FRI arrangement the tenant takes on responsibility for repairing the property, and the landlord insures the building and recovers the cost of the premium from the tenant as insurance rent — a sum reserved in the lease alongside the principal rent. The logic is simple: the landlord owns the asset and wants to control the policy that protects it, while the tenant, who enjoys the use of the building, bears the cost.

This division of labour has practical consequences. The landlord chooses the insurer, sets the sum insured, and handles claims. The tenant pays but has a legitimate interest in the policy being adequate, since the lease will normally oblige the landlord to reinstate the building after insured damage and may suspend the rent while the property is unusable. Leases therefore commonly set out what the landlord must insure against, how the premium is apportioned in a multi-let building, and what happens if the building is damaged by an insured risk. A landlord who insures carelessly — too low a sum insured, missing perils the lease requires — can find themselves in breach of their own lease.

What a commercial landlord policy should include

Buildings. The core of the policy. The building should be insured for its full reinstatement cost — the cost of demolition and debris removal, rebuilding, and the professional fees of architects, engineers and surveyors involved in reconstruction — not its market value. The two figures are frequently very different, and insuring at market value is one of the most common and most expensive mistakes commercial landlords make.

Loss of rent. If the building is damaged by an insured peril and the tenant cannot occupy it, the lease will usually suspend the rent. Loss of rent cover replaces that income while the building is reinstated. The indemnity period — how long the cover runs — should reflect a realistic worst case for rebuilding, including planning, design, tendering and construction, not an optimistic one. For a substantial or unusual building, reinstatement can take considerably longer than owners expect.

Property owners’ liability. The landlord’s liability to third parties arising from ownership of the premises — injuries on retained common parts, damage caused by the building to neighbours or passers-by. The tenant’s own public liability policy covers the tenant’s trade; it does not cover the landlord’s position as owner.

Noting tenants’ interests

Commercial leases frequently require the landlord to note the tenant’s interest on the buildings policy, and sometimes to have the insurer waive rights of subrogation against the tenant or to insure in joint names. These provisions protect the tenant from the uncomfortable outcome of paying the insurance rent and then being pursued by the landlord’s insurer after a fire the tenant accidentally caused. Whatever the lease says, the policy should match it. Ask your broker to check the insurance provisions of the lease against the policy — noting interests, waivers and any obligations about specific perils — so the two documents tell the same story.

When the tenant’s use changes

Buildings insurance is priced and written around what happens inside the building. A change in the tenant’s use — a café installing commercial frying equipment, a warehouse tenant starting to store hazardous goods, an office floor sublet to a new occupier with a different trade — can change the risk materially. If the insurer is not told, the landlord risks the policy not responding as expected when a claim arrives. The lease will usually oblige the tenant to notify the landlord of changes of use and to avoid anything that voids or increases the cost of the insurance; the landlord, in turn, must pass material changes on to the insurer. Make this a standing habit: when consent for a change of use, alterations or a subletting crosses your desk, tell your broker at the same time.

Multi-let buildings

A multi-let building adds layers. The landlord typically insures the whole structure under one policy and apportions the insurance rent between tenants through the service charge or a fixed proportion set in each lease. Points to watch: the sum insured must cover the whole building including common parts and plant; loss of rent cover should reflect the aggregate rent roll, not a single tenancy; each lease’s requirements about noting interests must be honoured; and the mix of tenants matters, because one tenant’s hazardous use affects the risk — and potentially the premium apportionment arguments — for everyone. Vacant units in an otherwise occupied building should also be disclosed, as insurers treat partly empty buildings differently from fully let ones.

Where a broker earns their keep

Commercial landlord insurance sits at the junction of an insurance contract and a property contract, and the two must be kept aligned as tenants come and go, uses change and rents move. An independent broker reads the lease’s insurance provisions, checks the sum insured basis, matches the indemnity period to a realistic reinstatement timetable, and handles the disclosure traffic — changes of use, alterations, vacancies — that keeps the cover reliable. Apex arranges this cover for landlords across the UK from our base in Bristol.

Frequently asked questions

Can the tenant insure the building instead of the landlord?

It happens, typically on leases of whole buildings to substantial tenants, but it is the exception. Most landlords prefer to control the policy protecting their own asset, and most institutional leases are drafted on that basis, with the tenant reimbursing the premium as insurance rent. If a lease does put the insuring obligation on the tenant, the landlord should still require sight of the policy and have their own interest noted.

Is loss of rent cover really necessary if the tenant is still bound by the lease?

Yes, because the lease will almost always suspend the rent while the building is unusable following insured damage — that is precisely what the rent suspension clause does. Without loss of rent cover, the landlord funds the mortgage and outgoings from their own pocket for the whole reinstatement period.

What happens if I under-insure the building?

Two problems. First, the policy may not pay enough to rebuild, leaving the landlord in breach of a lease covenant to reinstate. Second, most commercial policies apply average, reducing every claim proportionately where the sum insured is inadequate — so even partial losses are underpaid. Insuring on a professionally assessed reinstatement basis avoids both.
