Good to know
A few answers
before you start.
Can I book a boiler now?
We’re preparing the iPhone app and bringing installer partners on board. Paid bookings will open after launch checks. This website introduces the service; quotes, accounts and bookings are handled in the app.
What if I don’t know the answers?
You can choose ‘I’m not sure’ where it’s offered. The app explains the questions, and installations that need more information go for an engineer review before a package is confirmed.
Will you cover my home?
The initial service is for domestic natural-gas combi, system and regular boilers. Booking depends on approved installers, available packages and dates in your postcode. We’ll expand coverage as partners join.
Who supplies and fits the boiler?
The installer named in your package supplies the boiler, arranges delivery and completes the installation. You see their business, the installed price and the package terms before paying.
Do I need a servicing membership?
It’s optional. After installation, compare the available servicing benefits, prices and renewal and cancellation terms before deciding. Service appointments require you to choose a date.
