How it works

From a rough idea to real quotes

1

See the real range

Honest from, typical and up-to prices for each job, based on real UK work, not a salesperson's opening figure.

2

Price your own job

Use the calculator to get a range for your size, spec and area in a few seconds. No sign-up.

3

Get real quotes

When you're ready, get matched with vetted local installers and compare actual prices against the guide.

No sales pitch. Just real prices.

Most "get a quote" sites are built to harvest your details. We start the other way round: tell you what things really cost, then let you decide.

  • Independent guide prices, not a salesperson's opening figure
  • Free to use, no sign-up and no spam
  • We only make money if you choose to get matched with installers
  • Prices reviewed and dated, never scraped or made up
