Expanded UKAS accreditation and bespoke testing support from Winkhaus

Winkhaus Laboratories has once again demonstrated its leadership in the fenestration testing sector with the renewal and expansion of its UKAS accreditation. The updated scope now includes the 2024 addendum for PAS24:2022, solidifying them as a premier destination for customers with their comprehensive, accredited testing services.

As one of the first laboratories to be audited and approved by UKAS for testing to PAS24:2022, they now offer assessments to the new 2024 addendum PAS24:2022 +A1:2024, which introduces new tools to the attack testing for both PAS24 and TS007-1. A two year transition period to adopt testing to the new standard has been set for January 2027, with the laboratory team there to support customers in their compliance journey, helping them adapt efficiently and effectively. 

This falls as part of a wider update of security testing, with changes to the security part of building regulations (Approved Document Q or ADQ) expected in the near future, that will no longer reference earlier versions of PAS24, from 2016 or earlier, and that will widen the scope of ADQ from new build projects to include refurbishment projects for the first time. Manufacturers and fabricators will therefore need to plan a review of their existing test evidence, or plan to create fresh evidence in line with these standards changing.

“Transitioning to the updated standards and new addendum doesn’t mean starting from scratch,” explains Ade Collins, Laboratory Manager at Winkhaus UK. “Our approach involves reviewing existing test data, identifying gaps, and creating bespoke testing programmes that build on what our customers already have. This saves both time and money while ensuring compliance.”

This consultative approach is a hallmark of Winkhaus Laboratories. With almost 50 years of experience in testing, development, and product innovation, the team offers more than just pass/fail results. Their Technical Development Days are a standout service, designed to help customers refine products before formal testing begins. These sessions allow for early identification of any potential vulnerabilities, enabling iterative design improvements without the cost and delays of full-scale testing.

“Traditional testing can be a bottleneck in product development,” advises Ade Collins. “Our development days provide a low-risk environment to explore design tweaks and validate concepts, giving our partners confidence before committing to full accreditation testing.”

Winkhaus’ bespoke development process is further supported by in-house Computer Aided Design (CAD), 3D prototyping, and close collaboration between the product, technical, and laboratory teams. This integrated approach accelerates time-to-market and enhances product competitiveness, particularly valuable when working with new profile concepts or custom hardware solutions.

The laboratory’s capabilities span a wide range of testing services, including PAS24:2022 & +A1 2024 addendum for enhanced security performance, BS6375 parts 1–3 for doors and windows, BS EN1634-3 for smoke control, and TS007-1 for security hardware. With the latest UKAS accreditation updates, Winkhaus remains uniquely positioned to offer its customers a full-spectrum of testing aligned with the latest industry standards.

Established for over 25 years and a proud member of United Kingdom Accreditation Service (UKAS), the British Measurement and Testing Association (BMTA), and the Test House Studies Group chaired by Secured by Design, Winkhaus Laboratories continues to set the benchmark for quality, innovation, and customer support in the fenestration industry.
