Boiler installation: common questions
How do I know which boiler type I need?
An installer will look at your hot water use, water pressure and existing system before recommending one. Tell us what you have now when you start your quote.
Will someone visit before quoting?
Installers usually need to see the property, or photos of the boiler, pipework and flue, to quote accurately. The installer we match you with will tell you how they work.
