Budget 2026: What Does it Mean for Data and AI? 

AI and data firms will have been watching Chancellor of the Exchequer John Healey’s budget closely, but some observers might see his announcements regarding AI as somewhat insubstantial.  

The headline figure is an additional £700 billion pounds for AI safety and security. This may come as a relief to a public now inundated with stories about existential risk. 

But Healey is trying to spin a more positive vision, with funds going towards new initiatives and bodies as part of the government’s efforts to position the UK as a global leader in AI regulation. 

He has also confirmed an extra £140 million for the UK’s Sovereign AI Unit backing home-grown AI startups, and launched an AI Challenge Prize to support innovative uses for AI in the public sector. 

A boost for data centres 

More exciting for the AI and data sectors is a new ‘British data centre covenant’ aimed at getting more data centres built in the UK – and perhaps boosting public sentiment around them, too. 

This covenant will require operators to invest in communities, create jobs, and protect water supplies – likely to assuage local fears about the impact data centres have on the environment. 

In return, they will be given priority access to the national grid, and permission to build power generation facilities on site if necessary. 

This is all framed in terms of national sovereignty and security, where the aim is to keep sensitive data used by public services within the country. 

Is public opinion ready for it? 

Healey here seems to be walking the tightrope between the headwinds of public opinion and expanding economic opportunities. 

Significantly for Healey, the public still seems broadly wary of data centres. Polling by corporate affairs consultancy SEC Newgate in June found only about 35% of the population has a positive view of data centres, while 40% would not support new ones in their area even when they have the potential benefits explained to them. 

By baking safeguards into planning permissions, and framing their expansion in terms of national security, Healey will hope public sentiment starts to shift in favour of more data centres in their local area, with all the benefits to jobs and the local economy that implies. 

David Farmer, CEO at Harnham, said: 

‘It’s encouraging to see the government offer real backing to our AI and data sectors. We want to see continued support for these sectors, and that’s not possible without genuine investment in data centres. We’ll be following closely to see whether this initiative can provide a much-needed boost to what is fast becoming critical national infrastructure.’
