What is an EWC Code?
An EWC code (European Waste Catalogue code) is a 6-digit number that classifies the type of waste being transferred. Every Waste Transfer Note (WTN) in the UK must include an accurate EWC code. Using the wrong code is a compliance failure that can result in fines of up to £5,000 per offence from the Environment Agency.
EWC codes are also referred to as List of Wastes (LoW) codes in official EA documentation — the two terms refer to the same classification system with identical codes.
Hazardous vs Non-Hazardous EWC Codes
Some EWC codes describe waste that is classified as hazardous under UK law. On this page, hazardous codes are highlighted in red with a Hazardous badge — use the filter above to show only hazardous or non-hazardous codes.
In printed reference lists, hazardous EWC codes are marked with an asterisk (*) — for example 17 05 03* (contaminated soil). The asterisk means the waste must be consigned on a Hazardous Waste Consignment Note, not a standard WTN.
Can be moved on a standard Waste Transfer Note. Includes general waste, recycling streams, food waste, and most construction materials.
Requires a Hazardous Waste Consignment Note, a licensed hazardous waste carrier, and additional compliance steps. See the HP codes reference.
How EWC Codes Appear on Waste Transfer Notes
On a standard WTN, the EWC code is recorded in Part D (Waste Description) alongside a written description of the waste, its physical form, and quantity. Both the code and the written description must be accurate — a correct code with a vague description is still a compliance risk.
WasteBolt includes the complete EWC catalogue built into the WTN creation flow — search and select rather than typing codes manually, with hazardous codes clearly highlighted to prevent misclassification.
EWC Codes and Digital Waste Tracking (DWT) 2026
From October 2026, mandatory Digital Waste Tracking will require every waste movement to be recorded in the DEFRA national system. EWC codes are a required field for every submission. Businesses already using accurate EWC codes on digital WTNs will have significantly less preparation when their DWT mandate arrives.
Frequently Asked Questions
Are EWC codes the same as LoW codes?
Yes. EWC codes and List of Wastes (LoW) codes are the same classification system. The European Waste Catalogue was adopted into UK law and is sometimes referred to as the List of Wastes in official EA documentation. The 6-digit codes and descriptions are identical between the two.
How do I tell if an EWC code is hazardous?
On this page, hazardous codes are highlighted in red with a Hazardous badge. In printed lists, they end with an asterisk (*). Use the Hazardous filter above to see only hazardous codes. If a waste type has a hazardous EWC code, it must be consigned on a Hazardous Waste Consignment Note.
What happens if I use the wrong EWC code on a WTN?
Using an incorrect EWC code is a Duty of Care compliance failure. The Environment Agency can issue fines of up to £5,000 per offence in a Magistrates' Court, or an unlimited fine in a Crown Court for persistent non-compliance. Always verify the code is correct for the actual waste being transferred.
Can I use this EWC code list for free?
