ETL home — scheme overview
Why the list exists, who it is for, and how verified products support Net Zero procurement.
Energy Technology List (ETL)
The UK’s government-backed list of independently verified, energy-efficient products — around 8,000 listings representing the top 25% most efficient in their class.
Official source. The ETL website opens in a new tab so you read their guidance in their own words. This Greenways page is a bridge guide — not a replacement for the list. Primary product search is etl.energysecurity.gov.uk; GOV.UK is purchaser guidance only.

How the ETL can help
Use the list to find verified high-efficiency products by technology category, with impartial purchaser information that supports Net Zero buying decisions.
It is not a shop and not a Greenways catalogue — it is the UK government scheme’s product database and purchaser guidance.
What “listed” means
Listed products meet published energy-performance criteria for their technology category. Listing is not a payback figure, cost estimate, or tax-relief calculation.
Example technology note
Heat recovery ventilation (HRV) is a separate ETL category from boilers, heat pumps, and general HVAC. Product eligibility and category names come from the ETL product database.

Browse categories — professional foodservice, refrigeration, HVAC, lighting, heat pumps, and more.
For purchasers

Greenways vs the official list
The Greenways marketplace may show energy-efficient equipment examples that map to ETL product IDs for listing status and specifications. Those rows help you cross-check against the UK list.
Narrative payback, grant totals, and £/€ ranges on Greenways pages are illustrative Greenways modelling or other published sources — not ETL tax relief and not ETL-published savings.
Other Greenways pages will usually say “energy-efficient equipment” and point here for the UK list story.
