When choosing a trusted installer for your windows and doors, certification matters. Stafford Windows is proud to be a CERTASS-accredited installer, ensuring that our customers receive high-quality service that complies with UK standards. But what exactly is CERTASS, and why should it matter to you as a homeowner?
What is Certass?
CERTASS (Certification and Self-Assessment) is a UK-based certification body for the glazing and construction industry. It is one of the leading Competent Person Schemes, recognized by the UK government. The organization ensures that contractors and installers meet strict quality and compliance standards when working on residential properties.
Check out a video from Certass themselves explaining the benefits of choosing a Certass Registered Installer.
1. Guaranteed Compliance with Building Regulations
As a CERTASS-accredited installer, Stafford Windows ensures that all work meets the latest UK building regulations. This includes ensuring proper energy efficiency, structural integrity, and safety measures for every installation.
2. Peace of Mind with a Certification of Compliance
After your installation is complete, you will receive a certificate from CERTASS. This document confirms that your windows and doors comply with building regulations, which is essential if you decide to sell your home in the future.


3. Assurance of Skilled Workmanship
CERTASS requires its members to undergo rigorous assessments to prove their expertise and competence. By choosing Stafford Windows, you can trust that your installation is carried out by highly skilled professionals.
4. Enhanced Energy Efficiency
One of the key focuses of CERTASS is energy efficiency. By working with a CERTASS-accredited installer, you’re guaranteed solutions that help reduce energy loss and lower your utility bills, benefiting both your wallet and the environment.
5. Access to an Insurance-Backed Guarantee
All CERTASS-approved installers provide an insurance-backed guarantee. This means that even in the unlikely event of a company ceasing to trade, your installation is still covered.
