BSRIA extends performance testing capability
29th July 2025
UK: BSRIA has extended its UKAS-accredited testing capabilities to include the EN 14825:2022 standard following a comprehensive ISO 17025 audit by the UK’s National Accreditation Service.
The latest edition of the EN 14825 standard defines the operational conditions and calculation methodologies for determining the seasonal performance of heat pumps and air conditioners. The performance values calculated under this standard form an essential component of energy labelling for heat pumps, providing consumers with reliable efficiency data comparable with what they see when purchasing other domestic appliances.
The updated standard introduces comprehensive calculations for cooling performance and also incorporates hybrid heat pump systems.
Announcing the accreditation Peter Tse, BSRIA’s applied engineering business manager, said: “One of the two key conditions that must be met for a heat pump installation to be eligible for the £6,500 grant under the UK’s Boiler Upgrade Scheme is that the heat pump must be tested and shown to comply with the standards set by the Microgeneration Certification Scheme, a requirement of which is EN 14825.
“Our enhanced capabilities enable us to provide the industry with comprehensive testing that delivers precise seasonal performance metrics.”
BSRIA’s facilities include precisely controlled environmental chambers to enable testing across a comprehensive range of technologies, including air-source heat pumps, ground-source heat pumps, split air conditioning units and heat pump air curtains.
The laboratory now offers full compliance testing with all relevant standards: EN 14511 for thermal performance, capacity, COP, EER, and safety tests; EN 14825 for seasonal performance calculations; EN 12102 for sound power level testing; EN 16147 for domestic hot water heat pump performance rating.
