Buildings insurance for a leasehold flat: who is responsible?
For most leasehold flats the freeholder insures the building through a block policy paid via your service charge — here's how to check, and what you still need.
Buildings insurance for a leasehold flat: who is responsible?
If you own a leasehold flat, you almost certainly do not arrange your own buildings insurance — and you usually can't, even if you wanted to. The building is insured as a whole, and that is the freeholder's job, not yours. This is the single biggest difference between insuring a flat and insuring a house, and it catches a lot of first-time flat owners out.
Who insures the building?
For most leasehold flats, the freeholder (or the managing agent or residents' management company acting for them) takes out a single block buildings insurance policy covering the whole structure: walls, roof, foundations, shared hallways, and the fabric of every flat inside it. You don't need — and generally can't buy — a separate buildings policy for your own flat, because an insurer won't cover a slice of a building that someone else is already insuring in full.
You still pay for it, though. The cost is recovered from leaseholders through the service charge, usually as a named line alongside the ground rent and maintenance. So the freeholder buys the cover; you fund your share.
There is one common exception: if you own a share of the freehold (typically through a company the flat owners jointly own), the leaseholders arrange the block policy themselves. The principle is the same — one policy for the whole building — but the responsibility sits with the resident-owned company rather than an external landlord.
Check the lease — it is the deciding document
Do not assume. Your lease sets out exactly who must insure the building, who chooses the insurer, and how the premium is shared. In the overwhelming majority of flats it names the freeholder, but a few older or converted-house leases put the duty on the leaseholders. Reading the insurance clause takes five minutes and settles the question definitively.
You also have rights over a policy you're paying for. Under the Landlord and Tenant Act 1985 you can request a written summary of the buildings insurance and inspect the policy and receipts — useful for checking the sum insured matches the building's rebuild cost and that the excess is reasonable. Recent leasehold reform has tightened transparency further, giving leaseholders clearer sight of what they're charged and any commission built into the premium.
So what do you actually need to insure?
Your own contents — furniture, electronics, clothes, and valuables. The block policy stops at the structure and fixed fittings; it does nothing for your belongings if there's a fire, a burst pipe, or a theft. Contents insurance is your responsibility, it's optional, and for a flat it's usually one of the cheaper policies you'll hold. Check whether your lease requires you to hold it — some do.

FAQ
Do I need buildings insurance for a leasehold flat? Usually no. The freeholder insures the building through a block policy and recovers the cost via your service charge. Check your lease to confirm, and take out your own contents insurance for your belongings.
Can I buy my own buildings policy if I don't trust the freeholder's cover? Generally not, because the whole building is already insured under one policy. If the cover looks inadequate, request the policy summary you're entitled to and raise it with the freeholder or managing agent rather than buying a duplicate.
