Hazardous Substances Consent (HSC)

Hazardous Substances Consent (HSC) is a legal requirement in the UK under the Planning (Hazardous Substances) Regulations, ensuring that sites storing or using dangerous substances above specified thresholds assess, manage, and communicate their major hazard risks. HSC supports safe land use planning, protects surrounding communities, and aligns with broader regulatory frameworks such as the COMAH Regulations and Seveso III Directive. We help organisations navigate HSC applications, renewals, and ongoing regulatory engagement to maintain compliant, safe, and sustainable operations.
