Energy Technology List (ETL)

The ETL is a government-backed scheme featuring over 8,000 independently verified and accredited energy efficient products.


The Energy Technology List (ETL) is a scheme featuring over 8,000 independently verified and accredited energy efficient products across 62 sub-technology groups, backed by the Department for Energy Security and Net Zero (DESNZ).

The ETL helps contribute to net zero goals by increasing access to stringently tested products. It provides free, impartial support and information, enabling purchasers to easily compare product features and performance across suppliers so that UK businesses and the public sector can make greener energy choices.

All products listed, ranging from boilers and electric motors to refrigeration, have met a robust set of criteria and are placed in the top 25% of the market for energy efficiency in their class.

For purchasers, the ETL provides an easy-to-use procurement tool, while manufacturers can have their energy efficient products listed for free (subject to meeting energy performance criteria).

The list is updated monthly and the Department for Energy Security and Net Zero annually reviews the technologies and products that qualify for inclusion. ICF manages delivery of the scheme, including marketing and communications. Ricardo delivers the technical assessments of product applications and operates the annual Research Programme.

Purchasers can use the ETL to source and compare independently verified and accredited energy-saving equipment:


Manufacturers and suppliers of energy-saving technology can apply to have their products listed on the ETL for free:


At the request of users and purchasers from the Energy Technology List (ETL), we have worked with NBS to map the 140 ETL product categories against the UNICLASS codes:

This development delivers closer integration for users of the ETL, enabling users to seamlessly select verified energy efficiency products for use within their existing procurement and designing systems.

General Data Protection Regulation (GDPR): Information for ETL scheme stakeholders

The ETL has been in operation since 2001. During this time the Department for Energy Security and Net Zero (DESNZ), its predecessor departments and its contractors, have collected stakeholder contact records as part of the public task of delivering this scheme.

At DESNZ we’re committed to protecting the personal data we hold and to being transparent about the information we are collecting about you and what we do with it. GDPR gives individuals (whether these be customers, contractors or members of staff) more control over the ways in which businesses process personal data.
