Instant quote calculator for builders
Extensions, loft and garage conversions, brickwork, structural alterations and full renovations vary a lot in price, which is exactly why homeowners want a rough figure first. A guide range on your website tells them early whether you are the right fit, and sends you the serious ones.

Questions from builders
Big projects vary hugely. Is a guide range still useful?
Yes, because it filters. Someone with £5,000 for an extension sees the range and either adjusts their plans or moves on, and you spend your evenings quoting people whose budget fits.
Can it include driveways as well as building work?
Yes. If your website shows both, the calculator can list driveway and building jobs together.
How much does it cost?
£197 to set up, then £49 a month. The monthly plan keeps your calculator online, sends every request to your inbox, and covers price changes and help. You can cancel any time.
Do I need a website?
No. Put your link in your Instagram bio, Google Business Profile, Facebook page, WhatsApp or a QR code on your van or flyers. If you do have a website, it goes on with one line of code, or we install it for you free.
How do I cancel?
Use the “Manage my plan” link in your welcome email, which opens Stripe’s secure billing page. Your plan runs to the end of the month you have paid for, and then requests stop.
