We’re proud to have such an outstanding professional on board, ensuring we not only meet but exceed the necessary standards in the window and door industry.

Why Setting a High Bar Matters to All
The window and door industry plays a vital role in shaping the safety, efficiency, and quality of homes and businesses. Setting and maintaining high standards isn’t just about compliance — it’s about creating products that customers can trust to perform consistently while meeting environmental and regulatory expectations. At Listers, we are committed to raising the bar, ensuring product integrity and precision are at the heart of everything we do.
Auditing an organisation’s quality management system does not limit any auditor from further scrutinising product integrity and performance information.
