How To Classify Excavated Waste From Utilities Work
The disposal of excavated waste, produced during the installation or repair of utilities (e.g., tarmac, made ground or mixed spoil), without the requirement for classification testing was formerly covered by RPS 211 rules. These, along with RPS 298/299, have now been withdrawn. From 1 October 2025, classification must comply with the Street Works UK Material Classification Protocol, approved by the Environment Agency. Having been involved in early discussions with leaders in the utilities industry, we are uniquely positioned to advise clients on how classification testing for excavated utilities waste works under the new protocol.
Planned utilities work - In-situ testing of material to be excavated can be carried out prior to commencement on-site, meaning waste can be classified in advance and disposed of immediately after excavation.
Unplanned utilities work - Due to time constraints, classification now relies on risk-based assessments supported by on-site checks (litmus pH, PAK spray) and selective laboratory testing.
Waste Classification Testing of excavated utilities waste - To dispose of excavated utilities waste, such as material destined for landfill, waste carriers and landfill operators require detailed chemical analysis and accurate classification as either hazardous or non-hazardous. Under the Street Works UK protocol, a desktop risk assessment and site assessment are mandatory before excavation. Materials must be segregated, ensuring bituminous layers and sub-base layers are kept separate. In addition, at least 1% of qualifying excavations must undergo UKAS/MCERTS-accredited laboratory analysis. If the correlation between field and laboratory results falls below 93%, the proportion of samples tested increases to 3%.
Sampling, Testing & Classifying - If you intend to dispose of waste soil or other materials produced by utilities work, we provide a complete service. We collect samples from your site and carry out waste classification tests in a UKAS-accredited laboratory. Once analysis is complete, we prepare a detailed waste classification report within days of sample collection. We then liaise directly with disposal companies or landfill operators to ensure full compliance with the latest regulations.
Soil Test Kits - We offer a simple, quick, and affordable testing service. Our standard turnaround time is six to eight working days, with a fast-track option available in three to four working days. Each kit includes sample containers and clear instructions. Once you have taken the samples, we arrange collection and analysis at our UKAS-accredited laboratory, followed by a compliant classification report.
