Up to 4.5 gigawatts of floating offshore wind power is set to be developed in the Celtic Sea — enough to support 5,300 new jobs and inject £1.4 billion into the UK economy. The question isn’t whether that buildout is coming. It’s whether the businesses closest to it will be ready when it does.
South Wales sits at the edge of that wave. And for many companies in the region, the window to compete for a share of it may be opening right now.
A sea change arriving on Wales’s doorstep
The Celtic Sea is already central to the UK’s net-zero strategy. Crown Estate Leasing Round 5 has earmarked up to 4.5GW of floating offshore wind capacity for the region — a figure that translates, according to projections, into 5,300 new jobs and a £1.4 billion boost to the broader UK economy. Those numbers aren’t aspirational window dressing. They represent a concrete pipeline of contracts, construction activity, and long-term operations work that someone will win.
The question is who.
South Wales — and the Swansea Bay region in particular — sits close to where much of this development will take place, and it carries industrial history that, with the right preparation, could translate into genuine supply chain relevance. Ports, manufacturing capacity, engineering expertise: the raw ingredients exist. What many local businesses have lacked is a structured pathway into an industry with its own technical language, procurement processes, and expectations. That pathway is now being built.
What the Fit for Offshore Renewables programme offers
The Fit for Offshore Renewables programme — known as F4OR — is a 12-to-18-month initiative run by the Offshore Renewable Energy (ORE) Catapult, specifically tailored to the floating offshore wind supply chain. This latest round has been designed exclusively for businesses in the Swansea region, with a minimum of 10 companies selected to participate.
Selected businesses receive expert offshore wind consultancy support, guided through the specific demands of competing in this sector. The programme is built around practical outcomes: helping companies understand what buyers in the industry need, how procurement works, and how to position themselves to bid for and win contracts — both within the UK and internationally.
Dr. Davood Sabaei, F4OR Project Manager at ORE Catapult, described the opportunity plainly: “The UK’s offshore wind sector is experiencing substantial growth as we focus our efforts on meeting the Government’s ambitious targets for sustainable production and delivery of clean renewable energy. This has created immense opportunity for UK supply chain companies, and the F4OR programme has been specifically tailored to meet the needs of the floating offshore wind sector.”
For eligible businesses, the deadline to apply is Friday, August 29, 2025.
A track record built across the UK
F4OR isn’t a new experiment. Over the past five years, the programme has supported more than 170 companies across the UK, and on average, those participants have seen turnover increase by 26% — a meaningful result for small and mid-sized businesses navigating a competitive industrial market. Many have gone on to become established suppliers within the offshore wind sector.
Wales already has skin in the game. Thirteen Welsh businesses have taken part in previous F4OR rounds. Of those, three have achieved what the programme calls “granted status” — a designation indicating a company has reached a recognized level of readiness to compete in the offshore wind supply chain. It’s a modest but real foundation, and this third Welsh cohort builds directly on it. For businesses that have been watching the floating wind market from the sidelines, the programme’s track record lends credibility while the scale of the Celtic Sea opportunity lends urgency.
Who is behind the programme — and why it matters
The funding structure behind this round of F4OR reflects a deliberate alignment of interests. Jointly funded by The Crown Estate and the Swansea Bay City Deal — a partnership spanning four local councils: Carmarthenshire, Neath Port Talbot, Swansea, and Pembrokeshire — the programme is delivered by ORE Catapult, which brings both technical expertise and a national network of industry connections.
That combination matters. Crown Estate involvement signals that the organization responsible for leasing the seabed has a direct stake in ensuring local businesses can compete for the work those leases generate. Rebecca Williams, Director of Devolved Nations at The Crown Estate, said the programme would help South Wales businesses “take advantage of the many opportunities presented by the development of a new floating offshore wind industry in the Celtic Sea.”
The City Deal partnership adds a regional economic dimension that goes beyond individual companies. Jane Lewis, Regional Learning and Skills Partnership Manager at Carmarthenshire County Council, pointed to job creation and economic growth as core goals for communities across South West Wales. This isn’t a single organization acting in isolation — it’s a coordinated investment in Welsh clean energy capacity, with multiple institutions staking resources on the same outcome.
What to watch next
The August 29 application deadline is the immediate marker. After that, attention will shift to which companies are selected, how they progress through the programme, and — further out — how the Celtic Sea leasing round itself unfolds. Floating offshore wind at this scale remains an emerging technology, and the supply chains supporting it are still taking shape.
That’s precisely why timing matters. Businesses that build capability now, before contracts are awarded and rosters are filled, will be better positioned than those who wait. The programme won’t guarantee success. But for companies in South Wales with the right products, services, or technology, it may represent the clearest on-ramp currently available.
