How does the ETL align with the 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 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. For those products removed since 1st April 2017, the removal date appears on the list. A separate downloadable list of products removed before 1 April 2017 is available.

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.

How do I get the API?

The ETL API lets you add the ability to find energy efficient, ETL-listed products to your own websites and applications. All of the data available on the ETL product search service is available via the ETL API, including product features and images and the ability to search and filter products. You must register for a free API key to use the ETL API. After you've registered, we'll send your API key to you by email immediately.

Is the Enhanced Capital Allowance (ECA) still available?

No, the Enhanced Capital Allowance was removed in 2020. However, you may be eligible for Annual investment allowance (AIA) through which you can claim on most plant and machinery up to the AIA amount. You can read more about AIA on GOV.UK.

Who manages the ETL?

The ETL is managed by the Government’s Department for Energy Security and Net Zero (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 much does the ETL cost to use?

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