The Heat Pump KEYMARK Secretariat is pleased to announce that UL Solutions has achieved official recognition as a testing laboratory for Heat Pump KEYMARK certification. This marks another important milestone in UL Solutions’ expanding involvement in the scheme.
With this designation, UL Solutions becomes the 31st recognised testing laboratory under the Heat Pump KEYMARK scheme. The company’s laboratory in Carugate, near Milan, is now fully authorised to carry out the rigorous testing procedures required by the certification process.
This milestone empowers UL Solutions to offer a fully integrated service to heat pump manufacturers from initial product testing to final certification, streamlining compliance with European standards and reinforcing product credibility across the continent.
“Becoming a recognised testing laboratory within the Heat Pump KEYMARK scheme is a natural extension of UL Solutions’ support for our customers with comprehensive and integrated services,” said Alberto Vitaletti, senior product manager for HVACR at UL Solutions. “It strengthens our ability to help manufacturers demonstrate compliance and performance, especially in a market increasingly focused on energy efficiency and low-global-warming-potential technologies.”

Testing laboratories are a cornerstone of the KEYMARK certification process. They conduct independent and standardised tests that underpin the KEYMARK label, bolstering performance, safety and consistency. The inclusion of UL Solutions’ Carugate facility adds valuable capacity and expertise to this essential network.
“We are very pleased to welcome UL Solutions as a recognised testing laboratory within the Heat Pump KEYMARK scheme,” said Leopoldo Micò, head of the Heat Pump KEYMARK Secretariat. “UL Solutions’ dual role as both a testing laboratory and a certification body reflects the growing trust and alignment between KEYMARK’s rigorous procedures and industry leaders committed to sustainability and excellence.”
The continued expansion of the Heat Pump KEYMARK network underlines the scheme’s importance in helping the European heat pump industry meet ambitious climate and energy targets. UL Solutions’ extended participation is a strong vote of confidence in the KEYMARK’s value and integrity.
