RefusedAmlwch Port, Anglesey

Anglesey said no at Amlwch. Keep it that way.

In April 2026 Anglesey County Council refused plans to turn the old Octel works at Amlwch Port into an AI data centre, citing harm to the landscape, ecology and neighbours. The developer could still appeal or try again.

What we're asking for

To Isle of Anglesey County Council: Anglesey was right to refuse the Amlwch Port data centre. If the developer appeals or tries again, keep the refusal.

NatureThe refusal cites designated sites and ecology.

WatchAn appeal or a new application could follow.

If it comes back

Nothing is open right now. If the developer appeals or applies again, objections will count.

Good planning grounds include: impact on the Green Belt or countryside, energy use and carbon, water supply, noise, traffic, wildlife and heritage. Developers' promises are not guarantees: ask for them to be made binding.

Nothing is open. If an appeal is lodged, comments go to Planning and Environment Decisions Wales; watch Isle of Anglesey County Council for a resubmission.
