Llantwit Major sits far enough from Cardiff and Bridgend that the national installers treat it as a nuisance mile on the route map. The result is familiar to anyone who has tried to book a trade here: long waits for quotes, prices that drift, and engineers who would rather be somewhere closer to the depot. LMB quotes Llantwit Major from the same price list and the same diary as everywhere else on the patch.
From the old town to the estates
The town is really two housing stocks in one. The old centre is narrow lanes and stone buildings, where boilers live in tight spaces and flue routes need thought. Around it sit the post-war and modern estates, where most jobs are straightforward combi swaps done in a day. St Athan and the surrounding villages add everything from ex-MOD housing to newer developments.
The quote tool prices all of it the same way: answer a few questions, get a fixed fitted price in about 90 seconds, and anything genuinely unusual about your house is flagged and itemised before you book, not discovered when the floorboards come up.
What a new boiler costs in Llantwit Major
Installations start from £1,900 fitted, including the boiler, standard pipework and valves, a standard flue, system fill and commissioning, removal of the old boiler, your Gas Safe certificate and the Building Regulations notification. Finance options are available, and a £100 deposit reserves your installation date.
Certified every time, checkable every time
Every LMB installation is registered, certified and notified to Building Regulations as standard, with the manufacturer warranty set up in your name on the day. And the track record is public: 197 Google reviews at a 5.0 rating, written by named customers. Llantwit Major is a planned-jobs town for LMB, honestly a longer run from Pencoed than Bridgend or Pyle, so installs are booked on confirmed dates and the dates are kept. The reviews are the evidence for that claim too.
