Maritime and Coastguard Agency (MCA) (MCA)
The United Kingdom executive agency responsible for maritime safety, seafarer and ship standards, coastguard coordination and marine pollution functions.
The MCA is an executive agency of the Department for Transport. Its work includes HM Coastguard’s continuous maritime and coastal search-and-rescue coordination, ship survey and inspection, seafarer certification, administration of the UK Ship Register, maritime guidance and support for pollution prevention and response.
The agency implements and enforces relevant UK requirements and international obligations within its remit, while other bodies retain responsibilities such as independent lifeboat provision, local harbour control and accident investigation. The precise regulator or responder therefore depends on the matter and location.
Key Responsibilities of the MCA
- Search and Rescue (SAR): The MCA coordinates search and rescue operations through HM Coastguard (Her Majesty’s Coastguard), assisting distressed people at sea and around the UK coastline.
- Maritime Safety: The MCA sets safety standards for UK-registered vessels, ensuring compliance with national and international regulations, including regular inspections and certifications of ships.
