CERTASS is a Competent Person Scheme that was established in 2006. It is one of the largest and widely recognised regulatory bodies in the double glazing industry. It vets, regulates, and assesses all its members. This is how it ensures their double glazing installation meets all the building regulations and industry standards.
As per the building regulations, any double glazing replacement in your home has to be certified compliant by local authorities. CERTASS is a competent person scheme that monitors its members to assure compliance.
As a result, they are qualified to give the certificate of compliance after installation. This saves you the effort of having to seek it from your local building authority. They will also register your installation with the authorities for no additional charge.

CERTASS is licensed by the Department of Communities and Local Government, granting it the authority to assess and approve compliance with building regulations. Before registering an installation company, CERTASS conducts a thorough evaluation to ensure adherence to these regulations.
The vetting process includes assessing the company’s quality and understanding of industry standards. This rigorous scrutiny guarantees that any registered company meets high-quality benchmarks. Consequently, when you choose a CERTASS-registered installer, you can have confidence knowing that they are backed by a government-approved body.
Superior Quality Installation
To achieve CERTASS registration, installers must adhere to rigorous quality standards. Therefore, when you choose a CERTASS-registered installer, you can be confident in receiving exceptional quality and reliability. Your double glazing installation is guaranteed to endure over time.
Simplified Compliance Certification
If you choose an installer who is not registered with CERTASS, you will be responsible for obtaining a compliance certificate from your local building authority. Failure to comply can lead to legal consequences for both you and your installer. Furthermore, without the assurance of CERTASS registration, you cannot verify the installer’s skill, experience, or technical expertise until after the installation is complete. Consequently, there is no guarantee that your double glazing installation will adhere to building regulations.
Deposit Protection
By giving your deposit to a CERTASS certified installer, you can be confident that your funds are secure. These installers are held to the rigorous standards established by the CERTASS scheme. Additionally, the oversight provided by the regulatory body ensures that your rights as a customer are fully protected, making any attempt to deceive you impossible.
10-Year Guarantee
Trusted installers typically offer a guarantee on their work. When you choose a CERTASS-approved installer, you receive a 10-year guarantee. This ensures that your double glazing system will operate efficiently for at least a decade. Consequently, you can enjoy peace of mind knowing that your investment will endure for years without issue.
Insurance Coverage
Alongside a 10-year guarantee, CERTASS approved installers provide an insurance policy that complements this warranty. This policy safeguards the 10-year guarantee, ensuring that if your double glazing fails or does not perform as promised, you can rely on the insurance coverage to fulfill the terms of the guarantee.
