Offshore wind contributed to 19% of the UK’s electricity production in 2025, generating 52 TWh of power, as per the latest UK Offshore Wind Report from the Crown Estate.
“In just 25 years, offshore wind has become a core part of the UK’s energy mix,” said Julia Rose, Head of Offshore Wind at the Crown Estate.
Renewable energy sources accounted for 54% of UK electricity in 2025, up from 52% in 2024, driven by offshore wind and solar. Offshore wind was the UK’s largest renewable source last year, powering approximately 15.5 million homes.
The UK offshore wind sector is celebrating its 25th anniversary. The industry expanded from two turbines to 16.5 GW of installed capacity, reducing 20.8 million tonnes of CO2 emissions in 2025.
The UK has 46 fully commissioned offshore wind farms, 2,820 turbines, and 42 offshore substations. The supply chain now includes about 2,000 companies and factories.
The Crown Estate estimates the sector could support 94,000 jobs by 2030, up from 40,000, contributing GBP 18.2 billion to the UK economy over the next decade.
The report notes a 93 GW pipeline of fixed-bottom and floating offshore wind projects in various development stages.
In 2025, construction activities increased, with 11.4 GW under construction across eight offshore farms, including 801 turbines and 11 substations, compared to 7.8 GW the previous year.
Recent milestones include the UK’s Allocation Round 7, securing a record 8.4 GW of offshore wind capacity, and the award of seabed rights for 4.5 GW of floating offshore capacity in the Celtic Sea.
The UK’s seabed manager is preparing for a new seabed leasing round, expected to award around 6 GW of new projects in 2027.
