Every job ends with a completion certificate. It records the address, the date, what was removed, which elevations were cleared and that the brickwork was made good.

01

What it is for

Lenders, surveyors and buyers ask for evidence that failed cavity wall insulation has been dealt with. The certificate is that evidence.

What comes with it

  • The certificate itself, issued when the work is done.
  • The borescope photographs of the cleared cavity.
  • The quote you accepted, so the paperwork matches the work.
03

When you get it

On completion, once the last bricks are back and the site is cleared. Payment is on completion, so the certificate and the invoice arrive together.

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.
