Decra are Certass registered

Certass RegisteredAll Certass registered contractors are vetted to ensure they are qualified to carry out the replacement of windows and doors in accordance with the current building regulations and, once an installation is complete, Certass provides you with the Building Regulation Compliance Certificate for the work carried out.

Alternatively, notification and approval of the completed work can be sought from your Local Authority’s Building Control department directly. This can cost in excess of £250.

The Building Regulation Compliance Certificate is your proof of compliance with building regulations and will be required by your solicitor should you wish to sell your property. If you’ve lost your certificate, either you or your solicitor can contact Certass directly and a replacement will be issued, there is a small charge of £10 including VAT for replacement certificates.
By using a Certass registered contractor you’ll get:

  • Protection of deposit taken – in line with the insurance company’s policy wording
  • A 10 year guarantee covering completed window and door installations
  • An insurance policy to cover the 10 year guarantee, should the certass registered contractor cease to trade
  • An easy way of registering your replacement windows and doors with your Local Authority at no cost to you


"The project ran smoothly and the builders were very tidy" — Mrs Francis, Doncaster
