David Platt QC

Call 1987 • QC 2011

"One of the best QCs of his generation."
(Chambers & Partners)

Criminal Regulatory & Environmental

Health & Safety

David undertakes a wide range of health and safety work. Often this is linked to his disease and personal injury practice given his experience in industrial accidents, asbestos, hazardous substances and COSHH claims. Clients value the integrated service which he can therefore provide.

These cases have involved fatalities arising from alleged “aerotoxic poisoning”, liquid nitrogen, industrial accidents and all forms of injury arising in an employment or public context.

He acts in both the Crown and Magistrates Courts and at major Inquests.

Given his experience in environmental and pollution matters, he appears in linked prosecutions and pollution claims and in both the civil and criminal aspects of such cases. He has considerable experience of water pollution claims against the Environment Agency.


David has been involved in environmental matters for many years. He has been instructed in a large number of major public inquiries, in particular relating to non-domestic local authority planning. He has appeared in inquiries involving large waste applications (both incinerator and landfill operations), mineral applications, strategic manufacturing operations, together with both highway and local plan inquiries. Many of these were for Kent County Council.

He also undertakes general tortious pollution claims, in particular oil and other hazardous substance spillage claims. He has also wide experience of water pollution claims, both in a criminal and civil context. He is frequently instructed in nuisance claims.
