On the seabed and coast
We manage the seabed of England, Wales and Northern Ireland, including offshore energy, aggregates, and cables and pipelines. We also look after much of UK's foreshore.
Our brilliant places on the seabed and coast
On an increasingly busy seabed, we work closely with industry and stakeholders to help ensure the waters of England, Wales and Northern Ireland continue to be a brilliant place to invest. We also manage around half of the foreshore surrounding these areas.
Learn more about how we are unlocking potential to make best use of the UK’s world leading resources offshore as well as how we look after our foreshore.

Offshore Wind Leasing Round 4
With long coastlines, favourable wind conditions and, in many areas, shallow waters, the UK offers world-class natural resources for offshore wind, supported by a stable policy outlook, mature supply chain, and a clear route to seabed rights.
Round 4, our first offshore wind leasing opportunity of this scale in a decade, creates the opportunity for at least 7GW of new projects in the waters around England and Wales, delivering a robust pipeline for low-cost offshore wind deployment.
