What the site stores

  • Your cookie choice. When you answer the cookie question, your answer is stored in your browser so you are not asked again. It contains nothing about you.
  • Form protection. The survey and contact forms use a short-lived security token to stop automated submissions. It is not used to identify you.
02

Advertising cookies, only if you accept

We advertise on Google. If you accept cookies, Google Ads sets cookies that tell us when a visit from one of our adverts leads to an enquiry, and the site keeps the advert’s click reference for 90 days so your enquiry is matched to the advert. We use this to see which adverts work, not to show you adverts on other websites.

If you choose essential only, no advertising cookies are set. Google still receives a basic signal without cookies when an advert leads to an enquiry, and the advert’s click reference may travel in the page address instead.

You can change your answer at any time with the cookie settings link at the foot of every page.

Third-party content

The site loads its fonts from a font service. That request carries your browser’s ordinary connection data to the font provider but sets no cookies from this site.

Controlling cookies

You can clear or block cookies in your browser settings at any time. Blocking the form token will stop the forms working; email [email protected] instead.

What happens next

  • A free survey first We check the wall inside and out and look into the cavity with a small camera. Then you get a fixed price in writing.
  • The insulation comes out Bricks come out at the base of the wall, the old fill is drawn out, and the bricks go back in, pointed to match.
  • A completion certificate You receive a completion certificate when the work is done. If a lender or surveyor has flagged a filled cavity, that certificate is what you show them.
