As part of the 2024/25 Research Programme, 15 sub-technologies were assessed to confirm that the criteria continue to identify the top 25% most energy efficient products on the market in their class.

The ETL brings together around 8000 energy efficient products in one place, alongside independently verified performance data, product features and supplier information. This guide explains how to use the ETL to narrow your options, compare products efficiently and choose the best fit for your project.

The ETL helps the business and public sector compare energy efficient products with confidence. If you are considering an application as a manufacturer, the process itself is straightforward. You are likely to have all you need already, and with the right preparation, listing your energy efficient products on the ETL is a simple and easy way to demonstrate your products’ performance and connect with a wider audience.

After being listed on the ETL, a product becomes part of a wider ecosystem that supports informed procurement decisions across businesses and the public sector. It can help raise product visibility, build awareness, and drive engagement with relevant audiences, further amplified through the ETL’s own marketing activities.

We are pleased to announce that manufacturers of Packaged Chillers can now benefit from a streamlined application process for the ETL through our latest criteria alignment with Eurovent Certification. By using their existing Eurovent Certified Performance test reports, manufacturers can now demonstrate compliance with ETL performance standards.

By selecting ETL-listed products, organisations can move forward with confidence, knowing they are investing in high performing equipment designed to achieve real world results. Our case studies illustrate how these products are applied, in diverse settings, from community hubs and hospitality to healthcare and large commercial estates, delivering measurable energy and cost savings.

The ETL launched the Women Driving Change series on International Women’s Day in March 2025 last year to shine a light on the women shaping the energy efficiency sector, share their expertise and leadership stories, and make career pathways within the sector more visible. Over the course of the year, the series has featured conversations with women working across policy, manufacturing, design, construction, research and industry leadership.

2025 has been a year of meaningful connection for the ETL. Strengthened by new collaborations across government, industry and specification platforms. These integrations have made it easier for manufacturers to list and promote energy efficient products, and for specifiers, designers and buyers to make informed decisions that support energy efficiency goals.

In the latest instalment of our Women Driving Change series, we speak with Dr Zainab Dangana, Head of Sustainable Technology Services at Wates Group. Drawing on her background in architecture and a PhD in Sustainable Construction and Management, Dr Zainab discusses how research, innovation and collaboration can help transform the built environment.

We are pleased to announce that the ETL has been working closely with NBS, through the scheme’s API, to provide specifiers with an easier route to filter and select ETL listed energy efficient products at the point of design. As a result of this initiative, NBS Source now enables manufacturers to indicate if their products are ETL listed.

The launch of SKArating scheme’s updated Offices Environmental v2.0 framework will carry particular significance for manufacturers of ETL-listed products. The update deepens the link between SKArating and the Energy Technology List, meaning that ETL-listed technologies will play an even more prominent role in sustainable office fit outs.

In this latest instalment of the series, we speak with Caroline Bragg, Chief Executive of the Association for Decentralised Energy (ADE). She shares insights into her career journey, the lessons she has learned about leadership, and the vital role women play in shaping energy efficient technology.
