Specialist contamination clean-up

Specialist contamination clean-up is the response to hazardous contamination affecting drainage systems, requiring trained operatives with appropriate PPE and licensing. Common scenarios include sewage spills containing pathogens, fuel or oil contamination from forecourts, chemical spillage in industrial premises, and biological contamination from veterinary or healthcare settings. Across Greater London, specialist contamination work is regulated by the Environment Agency and HSE, with operators requiring waste carrier licences and trained operatives. Before specialists arrive, the area should be cordoned off, electrical circuits isolated where water is present, and occupants kept away from contamination. The service includes risk assessment, containment, removal of contaminated materials, biocide or neutralising treatment, waste disposal through licensed carriers, and a detailed report. Insurance typically covers specialist cleanup as part of buildings or environmental impairment policies, subject to claim notification requirements.
