Gas boilers must be installed by a person/contractor registered with the Gas Safe self certification scheme. Self certification schemes also exist for solid fuel and oil fired installations or alternatively, a Building Regulations application can be submitted for these works. All drainage work (above and below ground) in connection with a building including the installation of a sink, bath, shower, toilet etc, requires an application.
Do I need Building Regulations approval to install fittings and appliances or carry out drainage work?
