When your boiler stops working, you need a Gas Safe engineer who can get to you quickly and fix the problem properly the first time — not a contractor who'll keep you waiting and leave you with a part-finished job.
Based in Porthmadog, Lloyds Plumbing & Heating provides fast diagnostics and reliable repairs for homeowners and businesses across the Llyn Peninsula and wider Gwynedd area.
We work on all major makes and models, carry common spares on the van, and pride ourselves on honest advice — if your boiler can be repaired, we'll repair it. If it can't, we'll tell you straight.

We diagnose and repair the full range of boiler issues across gas and oil systems.
No heating or hot water
Boiler losing pressure
Leaks and dripping pipes
Strange noises (banging, whistling, gurgling)
Boiler keeps switching off
Pilot light won't stay lit
Frozen condensate pipes
Error codes and fault lockouts
A broken boiler isn't just inconvenient — in winter, with no heating or hot water, it's a genuine emergency. That's why we prioritise urgent breakdowns and aim to get out to customers as quickly as possible across our coverage area.
If you've got no heat, a suspected leak or a boiler that's locked itself out, give us a call straight away. We'll talk you through what to do over the phone if needed, and arrange the fastest possible visit.
Honest pricing, no hidden call-out fees, and a Gas Safe registered engineer at the door — not a stranger in a cheap van.
