Our Accreditations
GJT Joinery holds industry accreditations that give homeowners confidence in the quality and safety of our work. Every certification represents a genuine commitment to professional standards, not just a badge on a wall.
VELUX Certified Installer Programme (VCIP)
The VELUX Certified Installer Programme recognises installers who have demonstrated the skills, knowledge and professionalism to install VELUX products to the highest standard. As a VCIP-accredited installer, GJT Joinery is one of a select group of specialists certified directly by VELUX. This means every installation we carry out meets the manufacturer’s own quality requirements, and our work is backed by their approval.
TrustMark
TrustMark is the only government-endorsed quality scheme that helps homeowners find tradespeople they can rely on. Registered businesses are assessed for technical competence, customer service and trading practices. As a TrustMark-registered business, GJT Joinery has been independently vetted so you can book with confidence, knowing our work and conduct meet nationally recognised standards.
