We all know that product specification can make or break a project. That’s why Eurovent Certification and the Energy Technology List (ETL) have taken their collaboration to the next level.

In a market where confidence counts, third-party certification schemes are becoming go-to tools for identifying high-performing, trustworthy products. In the UK, Eurovent Certification and the Energy Technology List (ETL) provide reliable product selection tools for decision makers, allowing them to identify, compare and specify high performing products. Now their ongoing collaboration has taken a major step forward by aligning testing standards on rooftop heat pump units. This not only streamlines the ETL listing process for manufacturers but also simplifies product selection for specifiers.

The background

The ETL and Eurovent Certification have worked together since early 2024 to align testing standards so that Eurovent Certification test reports can be used to apply for the ETL, provided the products meet its strict energy performance criteria.

The Energy Technology List is a scheme for the UK market featuring around 8,000 independently verified and accredited energy efficient products across 65 sub-technology groups, backed by the Department for Energy Security and Net Zero (DESNZ). Products featured on the ETL must be in the top 25% for energy efficiency on the market, in their class. The scheme is free for both manufacturers and specifiers. It helps UK businesses, and the public sector make greener energy choices by selecting the most energy efficient products.

Eurovent Certification is a third-party certification body that assesses the performance of HVAC and refrigeration products. Trusted worldwide, Eurovent Certification programmes independently verify product performance data, via a stringent and impartial certification process, which includes laboratory testing, factory audits, software checks, and data consistency checks.

Product alignment

Rooftop heat pump units are the workhorses of retail and small commercial buildings, delivering reliable thermal comfort in a single, packaged system. Mounted externally on rooftops, these all-in-one units are capable of providing ventilation, cooling and/or heating directly to the indoor space. Beyond temperature control, rooftop units can enhance indoor air quality with high-efficiency filters that capture harmful particulate matter, ensuring cleaner, healthier air for occupants. Designed for applications where air recirculation is acceptable, many modern rooftop units also go a step further, offering advanced features like humidity regulation and free cooling to maximise comfort and efficiency.

Rooftop units join an ever-growing list of aligned products, including:

• Evaporative Air Coolers
• Refrigerated Display Cabinets
• Five Heat Pump technologies:
  • Air to Water Heat Pumps
  • Air to Air Heat Pumps, Split, Multi-Split
  • Water or Brine to Water Heat Pumps
  • Water to Air Heat Pumps, Multi Split
  • Air to Domestic Hot Water Heat Pumps.

Eurovent certified manufacturers can use their existing test reports to apply for the ETL, saving time, costs and complexity.

Benefits for manufacturers

Aligning Eurovent Certified Performance for Rooftops with the ETL’s strict criteria streamlines the ETL listing process while ensuring products continue to meet trusted, third-party performance standards. With the ETL backed by the UK Government, this alignment opens new doors, helping manufacturers reach public sector buyers and sustainability-focused businesses with greater ease and credibility.

Benefits for decision makers

Specifiers can trust that listed products meet the highest standards of efficiency and performance. Choosing products holding Eurovent Certified Performance and listing on the ETL not only removes uncertainty from the selection process but also supports decarbonisation goals, giving decision makers double assurance in choosing proven, sustainable solutions for their projects.
