About Costwise
Costwise is an independent UK guide to what home improvements really cost, so you can see a fair price before you ever speak to a salesperson.
Most "get a quote" sites are built to capture your details first and tell you the price later. Costwise works the other way round: every job has an honest from, typical and up-to price band and a free calculator, no sign-up. If you decide you want real quotes, we can pass your details to local installers, and that, plus the occasional marked affiliate link, is the only way we make money.
What we do
- Independent cost guides for 150 of the most-searched UK home-improvement jobs.
- A free calculator that ranges your job by size, spec and region.
- Prices that are researched, dated and reviewed, never invented.
How we stay honest
We publish the date each price was reviewed and only change it when the figures actually move. We never fabricate reviews, ratings or statistics, and our installer and affiliate partners never influence the numbers. Read how we price and our money and disclosure page.
