What Is Block of Flats Insurance?
Block of Flats Insurance — sometimes referred to as property owners' insurance — is a specialist policy that may provide protection for a building divided into multiple flats.
It often extends beyond a standard landlord policy and can include:
- The building structure – roofs, walls, stairwells, lifts, and external parts of the property.
- Communal areas – such as hallways, shared gardens, bike storage, and car parks.
- Property owners' liability – covering potential claims if a resident, visitor, or contractor is injured on the premises. Learn more about liability cover in our commercial property insurance guide.
- Loss of rent or alternative accommodation – which may cover income or rehousing costs if flats become uninhabitable after certain insured events.
Who May Need Block of Flats Insurance?
This type of cover is often relevant for anyone responsible for a building with multiple flats, including:
Freeholders
Who may own the entire building and need comprehensive cover
Share of Freehold Owners
Where leaseholders collectively own the freehold through a company
Residents' Management Companies (RMCs)
Which may be responsible for arranging insurance for communal areas
Right-to-Manage (RTM) Companies
Where leaseholders take over management duties from the freeholder
Landlords with Multiple Flats
Who may find a block policy more efficient than individual policies
Property Managers
Who often arrange insurance on behalf of owners or management companies

Block of Flats Insurance FAQs
Do individual flat owners still need their own insurance?
Yes. A block policy may cover the building and communal risks, but leaseholders or tenants typically need contents insurance for their belongings.
Can a lender's interest be noted on the policy?
Yes. Many insurers allow mortgage lenders to be noted, which may be required for leasehold lending.
We own the freehold collectively. Do we still need block insurance?
Yes. One block policy is usually arranged, with costs often split between the owners via service charges.
Who usually arranges the insurance?
Typically the freeholder, RMC, or managing agent arranges the policy. Premiums are often recovered via service charges.
Is terrorism cover compulsory?
Not always, though it may be required by some lenders in higher-risk areas.
Do directors of a residents' management company need cover?
Without D&O insurance, directors may be personally liable for management decisions.
