Radiators and heat emitters

Contact Research, Investigations & Test

UKCA Marking of radiators, heated towel rails, heat emitters and convector heaters becomes mandatory in Great Britain (excluding Northern Ireland) from 1st January 2023.  A UKCA Mark can only be applied to products successfully tested to EN 442 by a UK Approved Body.

As a UKAS accredited laboratory and UK Approved Body (0480) under the Regulation 305/2011, as amended by the Construction Products (Amendment etc) (EU Exit) Regulations 2019, BSRIA combines over 20 years expertise and their purpose built facility to provide manufacturers and importers with technical guidance to meet regulatory requirements in Great Britain (excluding Northern Ireland) to achieve the mandatory UKCA marking. 

In the UK, BSRIA is the leading laboratory for:

  • UKAS accredited testing to BS EN 442:2014 for UKCA Marking and Kitemark
  • Development of new models and design optimisation
  • Measuring low surface temperature (LST), critical for installations where the maximum operating temperature must be controlled to ensure compliance with the NHS Safe Surface Temperature guidelines
  • Product comparison testing and simulations
  • Performance testing of underfloor heating systems
  • Testing and troubleshooting with expert technical advice

Our fully automated environmental chamber enables us to accurately measure the thermal output of products at various water temperatures, and characteristic equations can be calculated for models of the same type.

BSRIA maintains a reference test installation which meets the requirements of the EN 442 standard. We continue to successfully participate in biennial ‘round robin’ testing to verify the reproducibility of the test values between test laboratories using a set of 'primary master radiators' throughout Europe.

Our expertise extends beyond testing to problem solving and expert technical advice.

Our experts provide a flexible and comprehensive test program tailored to meet your individual requirements.
