How our online boiler quote works
Tell us about your home and your current boiler. Our quote tool works out the right type and size of boiler and shows you three fixed-price options. Pick the one that suits you, choose when you would like it fitted and Lewis will call to confirm the details, often with a quick photo of your current boiler. There is no salesperson visit and no pressure.
Combi, system or regular?
Most homes with one or two bathrooms suit a combi boiler, which heats water on demand and frees up cupboard space. Larger homes with several bathrooms often do better with a system boiler and a hot water cylinder, so more than one shower can run at once. Older homes with tanks in the loft may have a regular boiler. If you are not sure, our quote asks the right questions and Lewis will talk it through with you.

Boiler Installation FAQs
How much does a new boiler cost?
A new boiler fitted by LWS starts from £1,995, including installation, removal of your old boiler, a system flush, a magnetic filter and Building Regulations registration. The exact price depends on your home and the boiler you choose. Our online quote gives you a fixed price in about 60 seconds.
Is the online boiler price really fixed?
Yes. As long as the answers you give match your home, the price you see is the price you pay. Lewis confirms the details with a quick call or photo before your installation is booked.
How long does a boiler installation take?
A straightforward like-for-like boiler swap is usually completed in one day. Switching boiler type or moving the boiler can take one to two days.
Should I get a combi or a system boiler?
Combi boilers suit most homes with one or two bathrooms and free up cupboard space. Homes with three or more bathrooms usually do better with a system boiler and hot water cylinder, so several showers can run at once. Our quote recommends the right type for your home.
