Notes on drainage
As mentioned, replacing existing drainage fittings on a like-for-like basis does need building regulations approval.
However, if the installation of the fittings will extend or make new connections to drainage pipes or an underground drain, the above-ground wastes and drains are controllable (i.e. need to be approved).
Drainage is legally a controlled service or fitting and you need to apply for building regulations permission before you start work. You can normally make your application using a building notice and can often submit this by telephone or online to your local authority building control team. Find out more at the link below.
