Offshore wind is becoming increasingly vital in the UK’s energy mix, delivering nearly a fifth of the nation’s electricity in 2025.

The Crown Estate’s latest UK Offshore Wind Report has also shown that the country currently has a pipeline of 93GW of fixed and floating wind capacity.

This number spans sites that are operational, under construction, in planning or with identified future potential.

This pipeline signals sustained confidence in the UK offshore wind market, building on significant recent breakthroughs, such as the record 8.4GW of capacity secured through CfDs in the AR7 round and the successful award of seabed rights for 4.5GW of floating offshore wind capacity in the Celtic Sea.

Currently, offshore wind remains the UK’s leading source of renewable energy, generating 52TWh in 2025, enough to power 15.5m homes.

In the past 25 years, since offshore wind was developed in the UK, it has grown from two turbines to nearly 3,000 fully commissioned in 2025, producing up to 16.5GW of grid-connected capacity. More precisely, the UK now hosts 46 fully commissioned offshore wind farms, 2,820 turbines, and 42 substations. 

Another 11.4GW of capacity is now under construction, including eight wind farms, 801 turbines, and 11 substations, up from 7.8GW in the previous year.

The report also notes that around 40,000 people are currently employed in the UK offshore wind sector, and that number could rise to 94,000 by 2030. Furthermore, the UK offshore wind supply chain comprises around 2,000 companies and factories, estimated to contribute £18.2bn to the UK economy over the next decade.
