Energy Technology List FAQ

About the ETL

What is the Energy Technology List (ETL)?

The ETL is a government-backed scheme featuring around 8,000 independently verified and accredited energy efficient products across 64 sub-technology groups.

We help contribute to Net Zero goals by increasing access to stringently tested products. We also encourage the purchase of more energy efficient technologies so that UK businesses and the Public Sector can make greener energy choices.

Whether choosing the right equipment now or in the future, or simply learning more about your options, the ETL provides free impartial support and information for you to easily compare product features and performance across suppliers – and help inform your purchase decisions.

Who manages the ETL?

The ETL is managed by the Government’s Department for Energy Security and Net Zero (DESNZ) formerly BEIS. ICF manages delivery of the scheme, including marketing and communications. Ricardo delivers the technical assessments of product applications and operates the annual Research Programme.

How does the ETL programme align with the UK Government’s Net Zero Targets?

Improving the energy efficiency of energy-related products is a key element on the journey to Net Zero, as acknowledged within the Government’s Product Policy Framework.The ETL scheme supports this by encouraging the purchase of more energy efficient technologies so that businesses within the UK can make greener energy choices that support the journey towards Net Zero.

How often are the individual product criteria reviewed?

The product criteria are reviewed at least once every four years. For products with a faster rate of innovation, the review period can be shortened.

Is the Enhanced Capital Allowance (ECA) still available?

No, the Enhanced Capital Allowance was removed in 2020.

How can I benefit from the ETL?
  • The application process is simple and getting your product listed is free.
  • Listing your product on the ETL ensures it’s aligned to the latest Government policies and associated with industry best practice.
  • Independent verification of a product’s energy efficiency performance from a trusted source, such as the Government, goes a long way in providing assurance for potential purchasers.
  • The ETL is an additional sales channel for your products that benefits from its own marketing and advertising activity.
  • Listing your products on the ETL gives them wider visibility and increased market exposure which can help reduce your transaction costs. Also, manufacturers will gain access to markets where Government Buying Standards (GBS) specify the ETL.
  • You can benchmark products against competitors’ using the ETL comparison tables to keep up to date with latest innovations.
How much does a product application cost?

There is no cost – it’s free to apply for accreditation, list your products, and use the ETL.

How long does the application process take?

The process typically takes between three to five weeks.

  • Following submission, the application undergoes a completeness check to ensure all required documentation is provided.
  • It then goes for technical assessment to ensure that the eligibility, performance, and information requirements – set in the ETL criteria – are met.
  • We will keep you updated of your application status and will be in contact if further information is required.
Can I apply for ETL listing if the company is not UK-based but supplying products into the UK?

Yes, you can apply for product listing on the ETL website.

Can I use the ETL mark for my listed products and where can I download it?

You can use the ETL mark for listed products in your marketing materials and sales channels, including your website. It provides assurance for purchasers who can be confident that the product has been independently verified and accredited and within the top 25% most efficient in the market in its class.

To download the ETL mark and for advice on how to promote your ETL listing, please view our Manufacturer’s guide: get the most out of your ETL listing. 

Where can I find the ETL criteria for my listed product?
I am interested in providing a case study for the ETL, who do I contact to find out how?

If you would like to provide a case study, please contact us at In the meantime, take a look at our existing case studies here.

How can I apply to the ETL Scheme?

Product applications are made online via the ETL Manufacturer Portal. You can also find guidance on how to submit a product application here.

What are the documents required to make an application?

Product applications typically require the following:

  • Completed and signed product application checklist.
  • Product Technical Specification.
  • Product Sales brochure/leaflet.
  • Declaration of Conformity.
  • Evidence that quality assurance systems/procedures are in place (typically evidenced through an ISO 9001 Certificate).

Test reports (the specific content of the test report will vary depending on the product and the requirements) You can find more specific guidance on what is required in section 1.3 of each criterion.

Do I have to test my products independently to be eligible for the ETL?

Not necessarily. The ETL criteria are typically aligned with commonly referred to test methods and, where applicable, regulations (e.g., Ecodesign). Each set of criteria lays out the applicable product application testing and verification routes (See section 1.5).

For each set of criteria, there are typically a variety of testing routes. These range from self-declaration to independent testing, including representative testing, where a representative model of a product family is tested – with the results applying to the family.

What if my application is declined?

  • The ETL features 64 technology categories and has around 8,000 energy efficient products that purchasers can quickly search and compare.
  • The scheme is Government-backed and impartial. It independently verifies products featured and is open and transparent about how it researches and creates its criteria.
  • Listed products align to the latest Government policies and are associated with industry best practice.
  • The ETL provides detailed product information and contact information for suppliers, including website links.
  • Energy efficient products are becoming more attractive as they can help save on running costs (OPEX) and likely have shorter pay-back periods than non-ETL compliant products.
  • Products across multiple categories can be easily evaluated to help you understand how, when combined, they can increase energy savings.
How much does the ETL cost to use?

There is no cost – it’s free to use the ETL.

How often is the list updated?

New products are added within 24 hours following approval. Products may be removed from the list for different reasons, for example if a product is no longer being sold in the UK and the manufacturer wishes to remove this from the list.
