How we make money

Our calculators are free to use. We make money in one way: when you ask for quotes, the installers you choose pay us a fee.

• Installers pay us the same fee whatever your savings result. Your numbers don't change based on who pays.
• We never share your details unless you tick an installer's box.
• We send you to no more than three installers.
• We don't sell or promote finance or loans.
• Pages with quote links carry an Ad label near the top.

Fee amount per quote request: to confirm (placeholder).
