Add a Costwise tool to your site

Our interactive UK cost map and every Costwise material calculator are free to embed on your own website, blog or client resource. They help your readers see what a job costs or work out how much material to order, and they take about a minute to add.

How it works

  1. Pick a calculator below and open its page.
  2. Open Put this calculator on your site and copy the code.
  3. Paste it into a page on your site. That is it, and it stays up to date automatically.

The code is a small iframe plus a short credit line. The only thing we ask is that you keep the credit link back to Costwise, which the code includes for you. You are welcome to use these on commercial sites. The tools run entirely in the reader's browser, set no cookies, and send nothing anywhere.
