A boiler service is cheap insurance against an expensive winter. A proper one checks combustion, seals, the flue, pressures and the safety devices, and flags the part about to fail before it leaves you cold. LMB does it that way across Caerphilly and the surrounding villages, with 207 Google reviews at a straight 5.0 behind the work.

Why the annual service matters

Most manufacturer warranties require an annual service to stay valid, so skipping one can quietly cost you the cover you paid for. A serviced boiler runs more efficiently too, and a small fault caught early is a cheap fix rather than a breakdown. For landlords, the service and gas safety certificate can be done in one visit.

LMB covers Caerphilly, Bedwas and Trethomas on the eastern edge of the patch, honest planned coverage. As a Gas Safe registered, Baxi Approved business the service is done to manufacturer standard, with new boilers from £1,900 if a replacement makes more sense.

Annual service
Hired Lloyd to carry out a boiler service and outdoor tap replacement. Very punctual, polite. Even giving our dog buddy a fuss. No mess or delays.
