This is an extract from a recent report “Global Offshore Wind Report 2026” published by GWEC. This extract specifically focuses on UK.
The offshore wind sector in the UK has experienced a year of significant progress, policy innovation and industrial expansion, reinforcing the country’s position as a leading market. Against a backdrop of heightened geopolitical uncertainty and renewed focus on energy security, the government has accelerated efforts to expand offshore wind deployment, strengthen domestic supply chains and reform the electricity system to integrate much larger volumes of renewable generation.
Turning auctions into a success story
A major milestone over the past year was the successful outcome of the UK’s seventh Contracts for Difference (CfD) allocation round (AR7), which secured investment in six fixed-bottom offshore wind farms and two floating offshore wind projects. Together, these projects represent 8.4 GW of new offshore wind capacity – enough to power almost 10 million UK homes annually – and are expected to unlock around GBP22 billion of private investment. The auction marked an important recovery following the difficulties experienced in AR5 in 2023, when no offshore wind projects bid due to inflationary pressures and supply chain cost increases. The government responded by substantially increasing auction budgets, reforming auction parameters and taking steps to provide greater investor confidence.
AR7 was also notable for the introduction of the Clean Industry Bonus (CIB), a new supply chain incentive designed to strengthen domestic industrial participation in offshore wind projects. The scheme rewards developers that commit to investing in UK manufacturing facilities, ports, skills and supply chain capacity, reflecting a growing belief within government that offshore wind deployment must be accompanied by broader industrial development and economic value creation if the sector is to maintain strong political and public support over the long term. Initially launched with an indicative budget of around GBP 200 million, the funding available subsequently increased to over GBP 544 million, following strong industry demand.
Government ambitions are for the scheme to unlock up to GBP 9 billion of private investment into UK manufacturing facilities, cleaner supply chains and port infrastructure. The UK has also continued to make progress in floating offshore wind, with the AR7 auction securing two commercial-scale floating projects. Alongside the leasing developments in the Celtic Sea, this has reinforced the UK’s position as one of the leading global markets for floating wind deployment and innovation. Floating wind is increasingly viewed by the government as both an energy security necessity and an industrial strategy opportunity, particularly for coastal regions with existing offshore engineering and oil and gas capabilities, such as Aberdeenshire in Scotland.
How the Crown Estate’s role aligns with government ambitions
The Crown Estate has played a central role in advancing the UK offshore wind pipeline over the past year. Most significantly, it continued progress toward the first commercial-scale floating wind leasing round in the Celtic Sea, which is expected to unlock several gigawatts of new capacity and support the emergence of a new industrial cluster in South Wales and southwest England. The Crown Estate has also progressed its Capacity Increase Programme, enabling existing offshore wind sites to increase generation capacity using more powerful turbines and improved project designs without requiring entirely new leasing processes. More broadly, leasing reforms and seabed management initiatives are increasingly being aligned with the government’s Clean Power 2030 ambitions.
Supply chain growth and industrial investment have accelerated considerably over the past year, supported by stronger co-ordination between government, industry and public investment institutions. These build on the funding pots and supportive policy frameworks outlined in the government’s Industrial Strategy and Clean Energy Industries Sector Plan, which both marked a significant shift towards a more interventionist industrial policy approach, with offshore wind positioned at the centre of efforts to expand domestic manufacturing capability and attract international investment. Vestas’ publicly stated intention to build a new nacelle facility in Scotland, valued at more than EUR 250 million and expected to create up to 500 direct skilled jobs, is considered the most significant development of the year, though it formed part of a broader wave of investment across UK ports, turbine servicing facilities, cables, fabrication and component manufacturing.
Great British Energy, the new state-owned clean energy investment body, has begun working alongside the Crown Estate, the National Wealth Fund and industry as part of a more coordinated industrial strategy to strengthen the UK offshore wind supply chain and manufacturing base. It has announced an initial GBP 300 million Offshore Wind and Networks Supply Chain Fund to support UK manufacturing facilities producing strategically important components such as blades, towers, monopiles, cables, substations and floating wind systems, as part of a wider GBP 1 billion commitment to clean energy supply chains during this parliamentary term.
In parallel, the Crown Estate announced plans to invest up to GBP 400 million into offshore wind supply chain infrastructure, including ports, manufacturing facilities and enabling infrastructure, reflecting its increasingly active role in industrial development alongside seabed leasing. The National Wealth Fund has continued to support offshore wind-related infrastructure and port investment, helping to crowd in private capital into strategically important industrial projects. Together, these interventions are supporting upgrades to ports, manufacturing facilities and supply chain capability intended to enable significantly larger volumes of offshore wind deployment over the coming decade, while increasing the proportion of economic value captured domestically within the UK.
Focus on integration, market reform and system flexibility
The government has increasingly recognised that offshore wind is no longer a marginal technology, but a central pillar of the national electricity system. Offshore wind now regularly provides around 20-30% of UK electricity generation. As a result, policymakers are focused on how to integrate very large volumes of offshore wind more efficiently into the electricity system. Electricity market reform, network planning and system flexibility are in the spotlight. The government and National Energy System Operator (NESO) are developing proposals around market reform to improve locational signals, reduce constraint costs and ensure the system is better optimised for high renewables operation.
There has also been growing momentum behind the development of multipurpose interconnectors, which combine offshore wind connections and international electricity interconnection infrastructure, improving network efficiency and reducing seabed disruption. Several important measures have been introduced to accelerate offshore wind deployment. In planning and consenting, reforms have focused on reducing delays while maintaining environmental protections. The establishment of the Marine Recovery Fund is intended to streamline compensation processes for environmental impacts and reduce consenting uncertainty for developers. In parallel, reforms to judicial review processes have sought to limit the ability for repeated legal challenges to delay nationally significant infrastructure projects.
Overcoming the barriers to growth
Despite this progress, significant barriers to growth remain. Skills shortages continue to affect the sector across engineering, construction, marine operations and grid infrastructure. Supply chain constraints – a challenge globally – are particularly significant for vessels, cables, substations and certain turbine components. Delays in permitting continue to affect deployment, often driven by chronic understaffing, inconsistent decision-making and increasingly risk-averse institutional cultures within statutory bodies and regulators. Grid infrastructure and delayed connection timelines are among the most significant challenges, with many projects facing connection dates extending well into the 2030s, threatening deployment schedules and investor confidence.
While reforms to the connections process are underway, substantial transmission investment and regulatory reform will be required to align network delivery with offshore wind ambitions. Finally, while the UK has established ambitious targets for offshore wind deployment to 2030, there remains less clarity around the post-2030 pathway. Political fragmentation, uncertainty around future market arrangements and widely differing projections for electricity demand growth – particularly linked to hydrogen, electrification and data centre expansion – are creating uncertainty about the scale and pace of offshore wind deployment required beyond the current decade. Maintaining investor confidence will require greater long-term policy clarity, stable market frameworks and continued strategic co-ordination between government and industry.
