Thatcham Research has been at the forefront of vehicle security since the 1990s when it introduced the New Vehicle Security Assessment (NVSA) to address levels of vehicle crime and launched the Thatcham Categories for Alarm and Immobiliser systems that is now established as an industry benchmark.

However, in an ever-changing world, we need to ensure that our services, processes and procedures are reviewed and where required, adapted to meet the needs of insurance companies, customers and the buying public.

As of 1 January 2019, all Thatcham Research security product assessments will be conducted under a new ‘Thatcham Security Certifications’ brand, an overarching service which encompasses the following product sectors and groups: 


  • Aftermarket
  • OEM
  • NVSA (New Vehicle Security Assessment – a constituent of the Group Rating scheme)


  • Electronic Alarms & Immobilisers
  • Vehicle Tracking & Asset Location Systems (including monitoring centres)
  • Whole Vehicle Marking
  • Locking Wheel Devices
  • OBD Electronic Port Protection

 The key product assessment changes are:

  • Thatcham will no longer undertake annual manufacturing site assessments – assessments will be carried out on the products only, and not the associated manufacturing processes.
  • Certification renewals will be carried out every 2 years, instead of annually
  • Products will only be assessed upon receipt of the relevant recognised Type Approval certificates
  • Certification process time reduced from a 6-8 week process, to 1-2 weeks
  • A new schedule of fees
  • A new Thatcham Security Certified logo

In order to transfer all current product certifications over to the new process before 1 January 2019 Thatcham will release the new Security Certification procedures and fees on 1 July 2018.

Any new security products submitted to Thatcham Research will be assessed using the new process from 1 July 2018.
