Street Works UK Protocol: Six months on – what have we learned and what’s next?
SOCOTEC Expert Webinars continues!
In this session, our Experts, Katy Strudwick and Tara Chisholm breaks down what the protocol really requires, what the Environment Agency expects, and what the latest laboratory data is revealing about real‑world performance.
Drawing on over 2,000 samples processed since October 2025, we explore the patterns emerging across blacktop, made ground and soils, why some operators are seeing unexpected hazardous results, and which issues are entirely avoidable with the right processes in place.
What You Will Learn
- How to improve correlation and avoid unnecessary hazardous classifications
- Why TPH dominates soil failures — and how to prevent it
- How composite sampling mitigates pH and heavy‑metal variability
- The regulatory boundaries between SWUK and WM3
- What the EA will be reviewing at the end of 2026 and how suspension risk is assessed
What to expect
- Free access to technical materials
- Opportunity to ask our experts
- Free to attend
This session is designed for utilities, contractors, consultants and highway authorities seeking clarity on compliance, risk and operational best practice under SWUK and WM3.

Street Works Protocol
Everything You Need to Know Before the Deadline
The Street Works UK (SWUK) Protocol is a new, risk-based framework designed to improve how excavation waste from utility street works is assessed, classified, and managed.
Developed in collaboration with the Environment Agency, this protocol replaces the previous Regulatory Position Statements (RPS 298) and introduces stricter requirements for risk assessments, waste segregation, sampling, and reporting.
From RPS 298 to Street Works UK Protocol
What is RPS 298 and when is it being withdrawn?
Regulatory Position Statement 298 (RPS 298), issued by the Environment Agency in the UK, provides guidance on the classification of excavated waste from street and utility works, particularly in situations where pre-removal sampling is not feasible.
