Product benefits

  1. UKCA Marking –
    The UKCA (UK Conformity Assessment) mark is the new UK conformity mark that came into force for construction products, including windows and doorsets, that are placed on the market in Great Britain (England, Wales and Scotland) after BREXIT. It covers most products that previously required the CE marking and will become mandatory from 30 June 2025. As a UK Approved Body (0086) for UKCA marking we can provide this service, so contact us to find out more.
  2. CE Marking –
    The Construction Products Regulation, via CE marking continues to be a visible declaration from the manufacturer or importer that the product meets the minimum legal requirements for supply of construction products, including windows and doorsets placed on the market within the EU. We can offer CE marking services from our Netherlands (Notified Body No. 2797) Centre of Excellence.
  3. Die BSI Mark of Trust –
    Organizations who achieve third party certification (for their products or services) can display the BSI Mark of Trust on their products. BSI certification goes beyond the minimum requirements, and the Mark of Trust is unique to BSI. As a result, it is not only acknowledged by consumers but also accepted by specifiers, architects and procurement professionals as a method of demonstrating ‘best in class’ around the globe.
