Our boiler installation service in Portishead fits new boilers sized right for your home. Lumina Bathrooms Ltd is Gas Safe registered and advises on the best boiler, then installs it safely and neatly.
The right boiler depends on your home's size, how many bathrooms you have and how much hot water you use. A boiler that is too small will struggle, and one too big wastes fuel. We advise on the best size and type for your home so it heats it well without costing more to run.

More Information
A new boiler must be fitted by a Gas Safe registered engineer, and we are. We install the boiler, connect it safely, test it and make sure it is running correctly before we leave. Doing the installation properly means a boiler that runs reliably and safely for years to come.
When we fit a new boiler, we handle the notification and registration so your installation is recorded correctly and your warranty is valid. You get the paperwork you need without having to chase it. It is part of doing the job properly rather than just bolting a boiler on the wall.
Lumina Bathrooms Ltd is Gas Safe registered and has installed boilers across Portishead and North Somerset for five years. We size the boiler to your home, fit it safely and register it properly, so you get reliable heating and a warranty that holds up.

STILL NOT SURE?
The cost depends on the type and size of boiler and how much work the installation involves, such as moving the boiler or upgrading pipework. We give a clear written quote after seeing your setup, so you know the price before committing. Quotes are free with no obligation.
A straightforward swap in the same spot usually takes a day. Moving the boiler to a new location, or changing the type of system, takes longer. We give you a clear timescale when we quote, so you know how long your heating will be off and can plan around it.
If your boiler is old, inefficient and breaking down often, a new one usually works out cheaper over time through lower running costs and fewer repairs. If it is fairly new with a one-off fault, a repair makes sense. We give honest advice based on your boiler's age and condition.
