When a boiler stops, you want two things: it sorted, and no nasty surprise on the bill. The honest version of a repair gives you both, a clear diagnosis of what has failed, a fixed price agreed before any work, and a straight answer on whether the boiler is worth repairing at all. LMB does it that way across Barry and the Vale, with 207 reviews at a 5.0 behind the work.

Repair or replace, the honest call

Most common faults, no heating or hot water, the boiler locking out, dropping pressure, banging or kettling, trace to a single part: a diverter valve, a pump, a sensor, an expansion vessel. Usually a worthwhile repair. Where a boiler is old, out of parts or repeatedly failing, you get told plainly rather than sold another repair, and if replacement makes more sense a fixed price is available online in about 90 seconds, with installations from £1,900.

As a Gas Safe registered business, the diagnosis, the repair and any gas work are handled by the same engineer, across Barry, Barry Island, Cadoxton and the Vale.

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.

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

Questions people ask

My boiler has stopped in Barry, can you help?

Yes. Call or WhatsApp 07712 646488 with the make and the fault, or a photo of any error code, and Lloyd will tell you the likely cause and what the visit costs before setting off.

Will you tell me if it is not worth fixing?

Yes, plainly. If the boiler is beyond economic repair you get told straight, with a fixed replacement price if you want one, rather than money spent on a lost cause.

Do you add a call-out fee?

You are told what the visit will cost before Lloyd sets off, so there are no hidden call-out fees afterwards. You decide with the number in front of you.

How quickly can you come out?

Where the diary allows, same-day for a breakdown. Barry and the Vale are covered from the Pencoed base; call 07712 646488 to check.
