About us

The Marine Management Organisation (MMO) was created in 2009 by the Marine and Coastal Access Act.


Driven by government’s aim for clean, healthy, safe, productive and biologically diverse oceans and seas, MMO’s purpose is to protect and enhance our precious marine environment, and support UK economic growth by enabling sustainable marine activities and development.

Our people

We are a team of around 300 people. We combine our Newcastle upon Tyne and London operations with a local presence around the English coastline in Brixham, Beverley, Harwich, Hastings, Lowestoft, North Shields, Hayle, Plymouth, Poole, Portsmouth, Preston, Scarborough, Shoreham and Whitehaven.

Our vision

A prosperous future for our seas, coasts and communities.

We must protect and enhance nature and our seas and use them wisely for the benefit of society and the economy – we need to deliver win-win outcomes, with a thriving environment supporting a thriving economy.

Our mission

As England’s marine manager, we protect and develop our seas, coasts and communities for the benefit of generations to come.

As our name says – we are here to manage our marine environment and we want to manage it well for the future.
