Legal Compliance and Certification

Building Regulation Compliance Certificate (BRCC): Upon completion of work, Certass-registered installers issue a certificate that proves the installation complies with current building regulations, including safety, security, and energy efficiency.

Crucial for Selling Property: This certificate is required by solicitors when selling or re-mortgaging a home to prove that windows and doors installed after April 2002 are legal.

Avoids Costly Inspections: It saves homeowners the time and money of hiring local authority building control to inspect the work

Financial Protection

Insurance-Backed Guarantees (IBG): All Certass-registered installers are required to provide an IBG. This protects the homeowner if the contractor goes out of business, covering the cost of the guarantee.
Deposit Protection: Certass ensures that customer deposits are protected even if the installer cannot complete the work.

Quality Assurance and Vetting

Rigorous Vetting: Contractors must prove their technical competence, with on-site audits conducted on application and subsequently every 3-5 years.
Annual Audits: Certass performs annual “desktop audits” to check that member companies maintain valid insurance and legal status.
Site Inspections: A percentage of installations are inspected on-site to verify that work meets strict quality and safety standards
