How to approach it

  1. 1

    Check the lease or shared-freehold agreement for any requirement to notify or get consent from other owners before altering plumbing, flooring or layout, since this is a common but easily missed condition.

  2. 2

    Confirm the waterproofing and floor build-up meets any requirements for sound insulation and leak protection to the flat below, particularly if changing from a bath to a wet room or altering the floor finish.

  3. 3

    Give neighbours advance notice of noisy work and likely dates, since goodwill here avoids disputes that a lease clause alone won't prevent.

  4. 4

    Establish whether the drainage serving the bathroom is shared with other flats before altering waste runs, since changes can have knock-on effects beyond your own property.

Your questions answered

Do I need permission from other leaseholders to refit my own bathroom?

It depends on the lease terms, many require notice or consent for structural or plumbing alterations even within your own flat, so it's worth checking before booking any work.

What happens if a leak from my bathroom affects the flat below?

Liability typically follows the cause of the leak and the terms of the lease or buildings insurance, which is why confirming waterproofing standards before work starts matters as much as the visual finish.
