The UK Modern Industrial Strategy makes Clean Energy Industries one of its eight high-growth sectors, the IS-8, and it is one of the largest supply chain opportunities in the whole plan. The government is targeting a doubling of investment to over £30 billion a year by 2035.
This page is our analysis of what that means for the engineering and manufacturing companies that supply clean energy, and what to do about it now. For the wider picture across all eight sectors, start with our UK Modern Industrial Strategy overview.
Why clean energy, and why now
Clean energy runs on a long chain of engineering and manufacturing suppliers. Offshore and onshore wind, nuclear, hydrogen, carbon capture, and heat pumps all depend on transformers, switchgear, cables, substations, steel towers, vessels, and the installation and maintenance behind them. The strategy names foundational inputs directly, steel, chemicals, critical minerals, and composites, which is exactly where many of our clients already operate. Wind turbine blades are a prime composites opportunity, and the strategy backs scaling up composites R&D through the National Composites Centre, with the UK composites industry already worth £13.4 billion a year (Composites UK).
The scale is significant. In 2022 there were around 450,000 people working in low carbon and renewable energy and its wider supply chain, and the government estimates that supplying the goods and services for the global transition could be worth £1 trillion to UK businesses by 2030. If you manufacture components, work with specialist materials, or provide technical services, this is a sector building domestic capacity on purpose.
What are the opportunities for clean energy suppliers
The UK Modern Industrial Strategy and the Clean Energy Industries Sector Plan are built around growing UK supply chains, not just deploying projects.
Funding aimed straight at the supply chain. A new £1 billion Clean Energy Supply Chain Fund under Great British Energy is designed to help companies grow capacity, with £300 million already committed to offshore wind. A £544 million Clean Industry Bonus rewards offshore wind developers that invest in UK supply chains, expected to leverage up to £9 billion of private investment. Great British Energy and Great British Energy Nuclear will invest more than £8.3 billion over this Parliament.
Catalytic public finance. The National Wealth Fund's £27.8 billion includes at least £5.8 billion targeted at carbon capture, hydrogen, gigafactories, ports, and green steel. The British Business Bank adds £4 billion of growth capital, and UK Export Finance has up to £80 billion to back exporters, including a critical minerals supply finance offer.
Each frontier industry, with its own pipeline. Offshore and onshore wind, where UK exports already exceed £2 billion a year. Nuclear, with £14.2 billion for Sizewell C, suppliers already benefiting from £2.5 billion of Sizewell contracts, and over £2.5 billion for the Small Modular Reactor programme. Carbon capture, with up to £21.7 billion of funding over 25 years and £9.4 billion of capital this Spending Review across the East Coast Cluster, HyNet, Acorn, and Viking. Hydrogen, with over £500 million for infrastructure. Fusion, with over £2.5 billion over five years and the STEP project at West Burton. Heat pumps, with a £7,500 grant per home and a Heat Pump Investment Accelerator helping manufacturers expand capacity.
Lower energy costs. The British Industrial Competitiveness Scheme will cut industrial electricity costs by up to 25% for energy-intensive manufacturers from 2027, including the foundational industries that supply clean energy.
Grids and connections. A reformed connections process and a new Connections Accelerator Service are speeding up grid build, with a strong push to grow the domestic networks supply chain in transformers, switchgear, cables, and steel towers.
What's live now
Already open or imminent: the £300 million Great British Energy offshore wind supply chain funding, the £544 million Clean Industry Bonus, Contracts for Difference auction rounds, heat pump grants and the Warm Homes programme, and the Connections Accelerator Service. The Critical Minerals and Steel strategies are strengthening the inputs your work depends on.
The honest picture, and why it works in your favour
The transition is more complex in practice than on paper. Reporting from Aberdeen, the Financial Times described a city whose 45,000-strong energy workforce sees offshore wind as its future but needs a steady transition to get there, with local suppliers warning they need continued work to stay committed while they diversify (Financial Times, August 2025). Supply chains need certainty, and that certainty is arriving unevenly.
That is the case for acting now rather than waiting. Developers and programme leads are being pushed to source more UK content, and the funding is explicitly there to grow domestic suppliers. The companies that win it are the ones a developer can find, verify, and trust quickly. Being visibly part of the clean energy supply chain, with current capability and the right credentials on show, is what gets you onto the bidder list while the pipeline is forming.
What to do now
We apply a structured 3-step process to ensure your company shows up and stands out from the first supplier search to the final shortlist. Heatload is a good example. They appear at the top of search for the terms that win them data centre heat load testing work, helping operators improve cooling efficiency and cut energy costs across the life of the data centre.
Step 1: Foundations and conversion
Step 2: Trust and consideration
Step 3: Awareness and network scaling
This is the heart of our B2B lead generation work for engineering and manufacturing companies: turning the investment this strategy is creating into qualified enquiries.
