Our boiler repair service in Portishead fixes noises, pressure loss and heating faults. Lumina Bathrooms Ltd is Gas Safe registered, so we find and repair boiler faults safely and get your heating working again.
Boilers show trouble in a few common ways: banging or gurgling noises, losing pressure, cutting out, or not heating water and radiators properly. Each points to a different fault. We diagnose the real cause rather than guessing, so the repair fixes the problem instead of masking it.

More Information
Boiler repairs must be done by a Gas Safe registered engineer, and we are. Working on gas safely is not something to cut corners on. When we repair your boiler, you can be sure the work is done correctly and the appliance is left safe to use in your home.
Sometimes a boiler is worth repairing, and sometimes it is throwing good money after bad. If your boiler is old and breaking down often, we will be honest that a new one may work out cheaper over time. We give you the facts so you can decide what is best.
Lumina Bathrooms Ltd is Gas Safe registered and has repaired boilers across Portishead and North Somerset for five years. We diagnose the real fault, carry out the repair safely, and give honest advice on whether a repair or a replacement is the better value for you.

STILL NOT SURE?
Look out for banging or gurgling noises, a drop in pressure, radiators staying cold, the boiler cutting out, or a yellow rather than blue flame. Any of these means it needs checking. Call us and, as a Gas Safe registered team, we will diagnose and repair it safely at your Portishead home.
It depends on the fault, but it is safer not to. A boiler that is banging, leaking or showing a yellow flame should be checked before you keep using it. If you smell gas, turn it off, open windows and call the gas emergency line. Then call us to inspect it safely.
We repair most common makes and models of gas boiler. As a Gas Safe registered team we diagnose the fault and source the right parts to put it right. If a boiler is genuinely beyond economical repair, we will tell you honestly and talk through replacement options for your Portishead home.
