Letting barns, yards or units? Commercial property owners cover that reflects who your tenants are and what they store.

Quick answer

What insurance do you need to let farm buildings for storage?

If you let farm buildings or yards to other businesses, you need commercial property owners' insurance covering the buildings at their full rebuild value, property owners' liability for claims arising from the premises, and loss of rent if a building cannot be used after insured damage. Every tenant's trade and what they store must be declared, because the contents of a let barn, such as caravans, vehicles, timber, fuel or packaging, drive the fire risk and can affect cover for the whole farm.

Why letting buildings changes your insurance

Letting out buildings is the most common form of farm diversification: half of farms in England let buildings, earning an average of £27,900 a year from it, according to Defra's Farm Accounts in England for 2024/25. Since May 2024, Class R permitted development allows up to 1,000 m² of agricultural buildings to change to storage and distribution, light industrial and other commercial uses.

Once a building is let, it is no longer under your day-to-day control. The tenant's activities, what they keep in the building and how well they manage fire risk all affect your insurance. Insurers will want to know about each tenant, and a single high-risk tenant can change the terms for the whole farm.

Tenants and what they store

Underwriters group tenants by fire risk. Dry storage of household goods or packaged products is usually straightforward. Higher-risk uses include caravan and boat storage (fuel, gas bottles and batteries), vehicle storage, timber and joinery, waste or recycling, hay and straw stored for others, and anything involving lithium batteries. Some will only be accepted with conditions, such as separation distances, sprinklers or restrictions on what can be kept.

Keep a simple register of every tenant, their trade, what they store and when they moved in, and send it to your broker at each renewal or when a tenant changes.

Leases, licences and recharging

Most farm lettings are on licences or short leases. The agreement should say who insures the building, usually the landlord, with the premium recharged to the tenant, and require tenants to insure their own contents, stock and liability. Ask tenants for a copy of their public liability certificate and make it a condition of the letting that they tell you before changing what they store or do.

Vacant buildings between tenants

Empty buildings attract arson, theft and squatting, and most policies restrict cover once a building has been unoccupied for 30 to 60 days. Tell your insurer when a building becomes vacant, keep it secure, remove combustible waste and inspect it regularly. If buildings are likely to stay empty for a while, a specialist unoccupied property policy may be needed.

Frequently asked questions

Who insures a farm building let to a tenant?

Usually the landlord insures the building and recharges the premium, while the tenant insures their own contents, stock and liability. Check the lease or licence, as it should say who is responsible.

Do I need to tell my insurer what my tenants store?

Yes. What is stored in a building has a major effect on the fire risk. Failing to declare a high-risk tenant could affect a claim for the whole site.

Is caravan storage on a farm insurable?

Yes, but insurers will ask about numbers, spacing, security, gas bottle and battery policies and whether caravans are stored inside buildings or in the open.

Does my farm policy cover buildings I let out?

Some farm policies will include let buildings if they are declared with the tenant's trade. Larger or higher-risk lettings are often better placed with a commercial property owners' insurer.

Where the information comes from

Our articles are compiled from a range of sources: regulators and public bodies such as the FCA, the Civil Aviation Authority, the Health and Safety Executive and Companies House; government publications and legislation; industry and trade bodies; insurer and market documentation; and published research and news reporting. Not everything stated originates from Miller & Partner. Where information comes from a third party we believe it to be accurate at the date of publication, but we haven't independently verified every external source and we don't warrant its accuracy or completeness. Where a point matters to a decision you're making, go to the original source and check it.

Figures, examples and case studies

Premium ranges, cost figures, limits and worked examples are illustrative only. They are not quotations, not offers of cover, and no cover is provided or implied on the basis of them. What you're actually charged depends on underwriting, and what you're actually covered for depends on the policy wording issued to you. Where an article includes a claim example, scenario or case study, it is illustrative unless we say otherwise — such examples are typically composites written to show how a policy section responds, and they don't describe an identifiable client, claim or settlement.

Interactive tools

Any calculators, cover checkers, risk assessors or similar tools on our site produce general guidance from the small number of answers you give them. They can't see your business, and their output is not a personal recommendation, an assessment of your actual risk, or a quotation.

Rules and market conditions change

Law, regulation, tax treatment, insurer appetite and policy wordings all change, sometimes at short notice. Content is accurate to the best of our knowledge on the date shown on the article and we don't undertake to update it as things move. An article you're reading some time after publication may be out of date.

Third parties and external links

References to insurers, underwriters, trade bodies, software, training providers or other organisations are for information only. They don't imply endorsement, recommendation, partnership or affiliation in either direction unless stated. We're not responsible for the content of external websites we link to.

Not legal, tax or accounting advice

Nothing here is legal, tax, accounting or regulatory advice. Where an article discusses statutory duties, contract terms or compliance obligations, take advice from an appropriately qualified professional on your own position before acting.
