The Crown Estate’s latest UK Offshore Wind Report highlights the growing role of offshore wind in the country’s energy mix, with the sector supplying nearly one-fifth of UK electricity generation in 2025. Offshore wind remained the UK’s largest source of renewable electricity, generating 52 TWh during 2025, enough to supply around 15.5 million homes.
Over the past 25 years, the sector has expanded from two turbines to almost 3,000 fully commissioned turbines in 2025, representing up to 16.5 GW of grid-connected capacity.
The report identifies a 93 GW pipeline of fixed-bottom and floating offshore wind capacity across the United Kingdom, including operational projects, projects under construction, developments in planning and future opportunities. This includes 8.4 GW of capacity secured through Contracts for Difference Allocation Round 7 and seabed rights awarded for 4.5 GW of floating offshore wind capacity in the Celtic Sea.
Around 40,000 people are currently employed in the UK offshore wind sector, with employment expected to increase to 94,000 by 2030.
Additional findings from the report include:
- Renewable energy accounted for 54% of UK electricity generation in 2025, compared with 52% in 2024, supported by growth in offshore wind and solar generation.
- The UK now has 46 fully commissioned offshore wind farms, 2,820 turbines and 42 substations.
- Offshore wind construction activity increased significantly, with 11.4 GW currently under construction, including eight wind farms, 801 turbines and 11 substations, compared with 7.8 GW in the previous year.
- The UK offshore wind supply chain includes around 2,000 companies and factories and is estimated to contribute £18.2 billion to the UK economy over the next decade.
