Frequent delays in offshore energy and infrastructure projects are threatening the UK’s underwater supply chain, according to the Global Underwater Hub’s 2025 Business Survey. The study found that almost all respondents believe work in sectors such as oil and gas, offshore wind, and defence is progressing too slowly, while more than 80% said developments are not moving at the pace the country requires.
The report, Minding the Gap, warns that firms may consider relocating overseas, with more than 80% of the sector indicating that UK supply chain capacity is not aligned with demand.
Despite these concerns, the survey shows the size of the UK underwater market has grown slightly, from £9.2 billion in 2024 to £9.4 billion in 2025. This increase reflects new construction projects and expanding export opportunities, which now account for 43% of all revenue generated by UK underwater supply chain companies.
The report highlights the risks of delays in domestic projects, noting that companies may pursue faster-moving international opportunities. To address this, it recommends accelerating domestic project delivery, providing clearer policy support, strengthening the skills pipeline, and promoting strategic diversification.
These measures are seen as crucial to maintaining confidence in the UK supply chain, improving utilisation, and ensuring the sector remains resilient and competitive in the global market.
