What is third party product certification?

It is the process of certifying that a manufacturer of a product, or individuals who are installing or maintaining that product have undergone an appropriate independent appraisal to confirm their compliance with the performance aspects of a specification for a particular product or product range, or its installation or maintenance. 

Third party certification is being increasingly specified by architects, contractors, local authorities, building owners and facilities and estates managers. It is a mandatory requirement for Secured by Design and it is also a preferred route for demonstrating performance of fire doors under Approved Document B of the Building Regulations.

To achieve third party certification, a manufacturer and their product will have to undergo a rigorous audit and testing process, ensuring that they have in place documented product specifications, installation instructions, and a factory production control system, all of which integrate with an approved Quality Management Scheme such as ISO 9001. Similarly, an installer or maintainer who is certified under a third party product installation or maintenance  scheme, will also be subject to both a rigorous initial vetting process and regular on-going checks to ensure that the quality of their work continues to meet the standards of the scheme.   

The benefits of achieving third party product certification

  • Helps generate new business for manufacturers, installers and maintainers by enabling them to tender for the increasing number of projects that specify third party certification
  • Provides manufacturers with a strong competitive advantage compared to those who are using test evidence alone to demonstrate the performance of their product
  • Helps generate repeat business for a manufacturer, installer or maintainer because it enhances their reputation for quality which in turn leads to customer loyalty
  • Shows due diligence on the part of the manufacturer, installer or maintainer enabling them to demonstrate that the product will continue to be fit for its intended purpose
  • Third party certification is voluntary and as such demonstrates a manufacturer’s, installer’s or maintainer’s commitment to quality 

The benefits of specifying third party product certification

  • It provides confidence in the manufacturer, installer, or maintainer of a performance critical product
  • It provides confidence that the quality of the product, its installation and its on-going maintenance will be consistent at all times
  • It helps to reduce the risk of product failure
  • It enables the specifier to make a commercially sound investment in performance critical products, their installation and on-going maintenance
