Regulatory context

Partial review. This is not an exhaustive review of applicable law.

United Kingdom: four jurisdictions

England and Wales have their respective environmental permitting authorities. In Scotland, water activities moved to EASR on 1 November 2025; records may retain CAR identifiers. Northern Ireland has a discharge consent regime under the Water (Northern Ireland) Order 1999. Each profile's constituent nation still needs confirmation.

Determine England, Wales, Scotland or Northern Ireland before assigning authority and regime.
Check the permit, potential exemptions and discharge conditions.
