Anything that touches gas has to be done by a Gas Safe registered engineer, by law, and for good reason. It is the one area of home maintenance where cutting a corner is genuinely dangerous. LMB is Gas Safe registered, with the registration there to check in the open, alongside Baxi Approved Installer status and 207 Google reviews at a straight 5.0.

The gas work we cover

Boiler installation, repair and servicing, gas pipework and supply alterations, cooker and hob connections, gas safety checks and the landlord gas safety certificate, and the diagnosis of any gas appliance fault. If you can smell gas, that is an emergency, call the National Gas Emergency line on 0800 111 999 first, and LMB handles any follow-up repair once the property is safe.

Coverage runs across Cardiff and the Vale from a Pencoed base, weighted to the western suburbs and the Vale side. New boilers are fitted from £1,900 with a fixed price available online in about 90 seconds.

Thank you LMB for fixing the fault, and servicing my boiler at short notice! Nice to have a reliable plumber local to Pencoed.
