OpenAI Pauses UK Data Center Investment Over Energy Costs and Regulation

Apr 10, 2026

OpenAI has paused its multi-billion pound Stargate UK data centre project planned for Cobalt Park in North Tyneside, citing concerns over high energy costs and regulatory uncertainty. The project, announced in September as part of a £31bn UK tech investment package, was to include thousands of AI chips through partnerships with Nvidia and Nscale, though it was much smaller than the US-based $500bn Stargate project. Key regulatory concerns include uncertainty over whether the UK will allow AI firms to train systems using copyrighted works under an opt-out system that previously angered artists like Sir Elton John. The pause represents a setback for the UK government, which has promoted AI development as central to economic growth, though OpenAI maintains it will continue investing in its London research hub.

OpenAI's pause of UK data center investment

▪OpenAI's Stargate UK agreement came alongside a wider £31bn package of UK tech investment.
▪OpenAI is pausing a multi-billion pound UK data centre project aimed at boosting its AI infrastructure.
▪Stargate UK was much smaller than OpenAI's US-based Stargate project, which committed a $500bn investment over four years to build new AI infrastructure.
▪OpenAI announced its UK data centre project in September.
▪Stargate UK included a large data centre in north-east England.
▪Stargate UK was based at Cobalt Park, North Tyneside.
▪Stargate UK included making thousands of powerful chips for AI development available as part of a partnership with tech firms Nvidia and Nscale.

Energy costs and regulatory concerns behind the decision

▪OpenAI's concerns about the UK's regulatory environment include uncertainty over whether the UK would change the law to allow AI firms to train their systems using copyrighted works.
▪The UK had previously been set to make training AI systems using copyrighted works an opt-out decision for creators.
▪Britain's energy prices had long been significantly higher than in the US even before the Iran war sent costs soaring.
▪The UK's opt-out approach to AI training on copyrighted works angered artists, including Sir Elton John.
▪OpenAI cited concerns about high energy costs and regulation as reasons for pausing the UK data centre project.
▪OpenAI will only move forward with Stargate UK when the right conditions such as regulation and the cost of energy enable long-term infrastructure investment.

Impact on UK's AI ambitions and government response

▪Technology secretary Liz Kendall said in a speech in January that the UK's AI sector had grown 23 times faster than the economy as a whole.
▪The £31bn package of UK tech investment was lauded as a sign of the country's potential to become an AI superpower.
▪The UK's AI sector has attracted more than £100bn in private investment since the government came into office.
▪London is home to OpenAI's largest international research hub.
▪OpenAI will continue to invest in talent and expanding its presence in the UK.

Perspective of UK Government

▪The £31bn package of UK tech investment was lauded as a sign of the country's potential to become an AI superpower.
▪The UK government has championed home-grown tech and AI development as a way to bolster economic growth.
