When it comes to replacing windows, upgrading your doors, or installing roof lights, homeowners and property developers want one thing: trust. In a crowded market full of bold claims, how do you separate the professionals from the rest?
You look for industry accreditation and certification.
At GL Glazing & Window Services Ltd, we proudly hold two prestigious accreditations: our Certass Membership Certificate and our Qualitymark Protection (QMP) Accredited Installer Certificate. These recognitions aren’t just badges on a wall, they prove our commitment to high standards, regulatory compliance, and excellent customer service.
Let’s explore why this matters for you and how these certifications ensure you receive quality service from start to finish.
What Is Certass and Why Should You Care?
Certass is a UK government-authorised certification body that assesses and monitors contractors in the building industry, especially in replacement windows, doors, roof windows, and roof lights.
Hiring a Certass-registered installer comes with several benefits:
- You get services from a company that has passed independent assessments
- Your installation will meet Building Regulations 2010 (Regulations 4 and 7)
- Your chosen company will undergo regular quality audits
- You will receive a building regulation compliance certificate without needing to contact the local authority
GL Glazing & Window Services Ltd joined Certass on 13th March 2021, and our registration (Member No. 20-1581) confirms we meet all required standards for domestic installations across the West Midlands.
Why this matters: Non-certified work can cause legal issues and complications during home sales or insurance claims. Therefore, choosing us means you receive legally compliant, insured, and trustworthy installation services.
What Is Qualitymark Protection (QMP) Accreditation?
In December 2023, GL Glazing & Window Services Ltd became a Qualitymark Protection Accredited Installer. This top-tier insurance-backed accreditation offers more than just proof of technical competence.
With QMP accreditation, you get:
- Assurance that we meet high standards in financial stability and customer care
- Access to Insurance Backed Guarantees (IBG) for qualifying installations
- Protection for your investment, even if our business ceases trading
- Verification by a Financial Conduct Authority (FCA)-regulated body
Bottom line: Your investment stays safe long after we complete the job.
Why Homeowners Should Always Choose Certified Installers
Investing in new windows, composite doors, or bespoke roof lights is a big decision. Choosing the lowest quote might feel tempting, but unqualified installers can cause more harm than good.
Without proper certification, you could face:
- Installations that don’t meet legal standards
- Voided warranty coverage
- Use of poor materials and shortcuts
- Legal troubles during property sales
However, working with GL Glazing means you benefit from:
- Certified Installers
- Insurance-Backed Guarantees
- Full Building Regulation Compliance
- Accredited Quality Standards
- Reliable, Experienced Professionals
