OpenAI has marked its expansion in the UK with its first permanent office in London.

The new office will be at Regent Quarter in King’s Cross London, comprising 88,500 square feet with the capacity for 544 team members.

Expected to open in 2027, the office represents OpenAI’s continued international expansion.

The firm also aims to make London its greatest research hub outside of the US, as its expansion in the nation reflects growing demand for AI research and products.

“The UK has an incredible depth of talent and a strong track record in AI,” says Phoebe Thacker, global head of data research programmes and London site lead at OpenAI. “London is already a key hub for our research and teams, and this new office gives us the space to keep building here.

“We’re seeing real momentum in how businesses, developers and institutions across the UK are using AI, and we want to support that growth. This investment reflects our long-term commitment to the UK and the role it can play in shaping how AI is developed safely and used to benefit people all over the world.”

The commercial office coincides with OpenAI’s many deals with the UK government, from its Memorandum of Understanding for a data residency, to agreements with the Ministry of Justice and its support for UK SMEs to expand their AI skills.

The office announcement, however, comes hot off the tails of OpenAI dropping its plans to construct a new data centre in the UK, citing high energy costs and regulatory hurdles.
