Trades You Will Need Next

Your own trade comes first. If a boiler replacement has raised questions about flue routes, pipework or radiators, these sister directories put you in touch with other Gas Safe registered engineers who can quote for the work.

A boiler flue often exits through a pitched or flat roof. These directories cover roofers who can repair flashings, replace roofline boards, re-felt a flat section or renew the whole covering, so the roof stays watertight after the heating work is done.

New heating often goes hand in hand with draught-proofing. These directories list window and door installers, conservatory specialists and double glazing fitters who can cut heat loss through the building envelope.

If the boiler is being installed in a garage or outbuilding, the driveway may need to be dug up for a new gas line. These directories cover resin, tarmac, concrete and gravel driveways, with contractors who can relay the surface properly.

Patios and block paving sit next to the house, and any ground disturbance for pipework can leave them uneven. These directories list block paving, natural stone and imprinted concrete specialists who can relay what was lifted.

Older driveways may already be damaged, and the work of a heating engineer is a good moment to sort them out. These directories cover repair, resurfacing, cleaning and restoration, so a tired drive does not undermine the new installation.

A new boiler is often part of a wider energy upgrade. These directories list MCS-certified solar installers who can add panels to the roof or ground, giving you a way to offset the gas you still use.
