Why check your quote here
A quote tells you what one installer wants to charge. Our ranges tell you what the market charges, so you know which questions to ask.
01
Ranges from three independent sources
We publish a price range only when at least three separate sources back it. When they don’t, we say so.
02
Real quotes, clearly labelled
Prices homeowners share on forums sit next to installer price lists, marked as user-reported.
03
Nothing to sell you
We don’t install, quote or pass your details to installers.
