A boiler service is one of those jobs where the difference between done properly and done quickly is invisible until something goes wrong. A real service checks combustion, seals, the flue, pressures and the safety devices, and flags the part that is about to fail before it leaves you cold. LMB does it that way, and the public record backs it: 207 Google reviews at a straight 5.0, with the owner doing the work.
Why the annual service matters
Most boiler warranties require an annual service to stay valid, so skipping one can quietly cost you the cover you paid for. Beyond that, a serviced boiler runs more efficiently, which shows up on the gas bill, and a small fault caught at a service is a cheap fix rather than a breakdown in January. For landlords, the service and the gas safety certificate can be done in the same visit.
LMB covers Cardiff and the Vale from a Pencoed base, weighted to the western suburbs, Llandaff, Radyr, Creigiau and the Vale side. As a Gas Safe registered, Baxi Approved business, the service is done to manufacturer standard, and if the boiler is genuinely beyond economic service, you get an honest fixed price for replacement, with installations from £1,900.
