Leaks between flats: who is responsible?

It depends on where the leak starts, and what your lease says.

Reviewed by Mark Cunningham AssocRICS MTPI MIFSM, Leasehold Director. Last reviewed 3 October 2026.

Most leases make each leaseholder responsible for the inside of their flat, including pipes serving only that flat. The landlord or RMC is usually responsible for the structure, roof and shared pipes.

What to do

  1. Stop the water if you can and tell your neighbour.
  2. Report it to the managing agent with photos.
  3. Allow access for investigation; most leases require it.

Insurance

Escape of water is often covered by the buildings policy, subject to an excess. Repeated claims push premiums up for everyone, so fixing the cause matters.
