Deposit Indemnity Protection & 10 Year Insurance Backed Guarantee


Member of CERTASS

Certass, licensed in 2006, is a not for profit government approved Competent Person Scheme.

Competent Person Schemes were set up by the government to provide an alternative to submitting a building notice or using an approved Local Authority inspector for certain home improvements and building works. Since 1st April 2002, all replacement window and door installations must be certificated and there are two ways of achieving this.

All 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.

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.

We are located at:

Supreme Installations (S.E.) Ltd

Unit 1 New Farm
