Key Takeaways

  • Wylfa on Anglesey chosen to host the UK's first small modular reactors
  • Publicly‑owned Great British Energy‑Nuclear will build three SMRs, with Rolls‑Royce SMR as likely supplier
  • Government-backed £2.5 billion project expected to create about 3,000 jobs and start in 2026

Wylfa SMR project details

The UK government has announced that publicly owned Great British Energy–Nuclear (GBE‑N) will build the country’s first small modular reactor (SMR) power station at Wylfa on Anglesey, with Rolls‑Royce named as the preferred designer subject to final contracts.

Work will begin next year, with the aim of generating power by the mid 2030s A first-of-its-kind nuclear power station is to be built on Anglesey, bringing up to 3,000 jobs and billions of pounds of investment

The plan initially comprises three SMR units, with scope to expand the site to as many as eight modules.

Work is due to begin on site in 2026 and the first units are targeted to supply power to the grid in the mid‑2030s.

The project is backed by a £2.5bn UK government investment and is described as capable of supporting up to around 3,000 peak construction jobs and supplying power for roughly three million homes.

Wylfa project plans

Government and industry spokespeople frame the Wylfa decision as a strategic move to boost energy security, revive the local nuclear legacy and create a fleet-based approach to factory-built reactors.

Ministers have signalled plans to cut red tape and change planning rules to speed delivery, while Great British Energy-Nuclear and Rolls-Royce executives described the scheme as the start of a long-term, factory-led commitment to energy independence and local investment.

Industry figures emphasised the potential for training, jobs and lower local construction impacts through modular approaches.

The decision is portrayed as a boost for Anglesey, reviving Wylfa’s nuclear heritage, supporting the Anglesey Freeport and linked investment zones, and promising local jobs and training.

Reports estimate the SMR plant could support up to 3,000 construction roles at peak and attract billions in infrastructure investment through the mid-2030s.

Some local sources and politicians, however, insist on guarantees for community benefits and clear timetables given previous failed revival attempts.

Reactions and technical caveats

Not all coverage is uniformly celebratory: international reaction and technical caveats appear across sources.

The US ambassador said he was 'extremely disappointed' that US firm Westinghouse’s gigawatt-scale proposal was not chosen and argued there are cheaper, faster and already approved options.

Mainstream outlets such as New Civil Engineer highlight that final contracts, regulatory approvals, and first-of-a-kind costs and timetables remain unresolved.

This mix of diplomatic friction and procedural uncertainty tempers purely promotional narratives.

Political and community reactions

Political reactions vary: national leaders and Welsh ministers welcomed the decision as a boost for jobs and energy security.

Energy Secretary Ed Miliband called it an "exciting" step, while local politicians and community groups urged clear timelines and benefits after earlier failed attempts to revive Wylfa.

Several outlets underlined export potential and the programme's role in broader nuclear commitments (Sizewell C, Hinkley Point).

Some local reporting noted opposition to new nuclear in parts of the community.
