Frequently Asked Questions

Everything you need to know about our boiler installation service.

What is included in a new boiler installation?
Installation includes a home assessment, boiler recommendation, removal of the old unit, installation of the new boiler, system testing, handover, warranty registration, and a gas safety check.
How do I know if I need a new boiler instead of a repair?
Replacement is often worth considering if the boiler is old, unreliable, inefficient, uneconomical to repair, or has recurring faults. The decision depends on age, condition, repair cost, and parts availability.
Can you recommend the right boiler for my home?
Yes. We assess your property, hot water demand, space, and heating system to recommend a suitable boiler type and output.
Do you remove the old boiler?
Yes. Removal of the old unit is included as part of the installation service.
Is warranty registration included?
Yes. Manufacturer warranty registration is included with new boiler installations.
Do you test the system after installation?
Yes. System testing and handover are part of the installation process so you know how the new boiler operates before the job is completed.
Can you replace my boiler with a more energy-efficient model?
Yes. Modern boilers are generally more efficient than older models, and we can recommend options that better match your home and usage.
Can I replace a combi with a system boiler or vice versa?
In many cases yes, but it depends on your home, hot water demand, pipework, cylinder space, and budget. A system change is more involved than a like-for-like replacement.
Will a new boiler help lower energy bills?
It can, especially if your current boiler is very old or inefficient. Savings vary based on insulation, controls, usage, and the condition of the wider heating system.
Can you install a boiler for a flat?
Yes, subject to access, flue position, and the suitability of the system for the property.
What should I ask before installing a new boiler?
Good questions include what boiler type suits the property, what output is needed, whether controls should be upgraded, how long the work will take, and what warranty is included.
Do I need a site survey before a quote?
For many installations, yes. A survey helps confirm boiler size, flue route, condensate disposal, controls, pipework, and any system changes needed.
