Who pays to repair a flat's fire door?

Read the lease first. It decides.

Plenty of leases make the flat's front door part of the building, so the landlord looks after it. Some give it to the leaseholder. The doors on the shared stair and corridor are normally the landlord's either way.

Tall blocks add a legal duty to check. In a building over 11 metres with two or more homes, the Fire Safety (England) Regulations 2022 say the responsible person has to check communal fire doors every three months and flat entrance doors every year, as far as they can. Checking isn't paying, though, and the rules don't say who covers the repair.

Residents should ask their managing agent. Landlords should get the answer in writing before the crew turns up. We repair either door once the right person has agreed.
