Britain’s digital infrastructure just had its biggest year ever. Businesses collectively poured more than £11 billion into UK data centres in 2025, driven almost entirely by the insatiable appetite for AI compute power.

Who’s writing the checks

NVIDIA leads the charge with plans to invest up to £11 billion in what it calls “AI factories” across Britain. That commitment includes the deployment of up to 120,000 Blackwell Ultra GPUs, representing a historic expansion of the company’s footprint in the country. Blackwell Ultra chips are NVIDIA’s latest-generation processors designed specifically for training and running massive AI models.

Microsoft has committed $30 billion toward AI and cloud infrastructure in the UK, with roughly $15 billion earmarked for data centre capital expenditures over the coming years.

Google has also entered the picture with a £5 billion pledge to Britain’s AI sector spread over two years.
