Boiler FAQs
How long does a boiler installation take?
A standard boiler replacement typically takes 1-2 days. More complex installations (e.g., relocating the boiler) may take longer.
Do I qualify for a free boiler replacement?
You may qualify through the ECO4 scheme if you receive certain benefits, have a low household income, and your current boiler is old or inefficient. Use our eligibility checker to find out.
What's the difference between combi, system, and regular boilers?
Combi boilers heat water on demand (no tank needed), system boilers work with a cylinder for stored hot water, and regular boilers require both a cylinder and a tank. We'll recommend the best option for your home.
How much can I save with a new boiler?
Replacing an old G-rated boiler with a new A-rated condensing boiler can save up to £580 per year on heating bills for the average home.
