August 28, 2026, (Inside AI) — The UK government has rejected a Green party call for an immediate moratorium on large-scale AI datacentre construction, setting the stage for a national debate over energy, water, and economic security.
Green party leader Zack Polanski demanded a pause on what he called “energy-guzzling, water-guzzling datacentres,” but Labour officials countered that halting development would damage jobs and national security.
The dispute arrives during one of the UK’s worst droughts in years. Datacentres currently consume about 2.5% of UK electricity, a figure projected to quadruple by 2030.
Polanski criticised Labour’s decision to classify datacentres as critical national infrastructure, calling the move “outrageous.”
“To most people critical infrastructure means hospitals, water, electricity. It doesn’t mean artificial intelligence.” Zack Polanski, leader, Green party
He added: “Right now the government is putting our communities, our water security and our climate ambitions second to the demands of tech giants.”
The government rejected the moratorium proposal, which would have allowed only local-scale datacentres for community use.
“A pause on building new datacentres would simply send investment and good jobs abroad, while leaving Britain dependent on overseas computing for the processing of sensitive health and defence data.” Government spokesperson
Officials said critical national infrastructure status does not grant datacentres priority access to water or electricity during shortages. In England, datacentre water use represents less than 1% of non-household consumption.
The political row mirrors growing tensions in the US, where datacentre policy has become a midterm election issue. In Scotland, the SNP government appears to be “inching towards a moratorium” amid voter pressure.
Local disputes have erupted from Devon to Buckinghamshire and Cardiff to Fife over noise, heat, traffic, and visual impact on house prices.
AI minister Kanishka Narayan linked datacentre expansion to defence sovereignty, saying the public “doesn’t just want foreign billionaires to own things that matter to our lives.”
‘No Blank Cheque’ but No Pause Either
The government insists its refusal to pause development does not mean automatic approval for every project. Developers should “prioritise clean power, use water responsibly, create British jobs and supply chains, and provide investment to the communities in which they are built,” a spokesperson said.
But campaigners warn that some developers are planning their own gas-fired power stations to bypass grid connection delays. Tech equity group Foxglove called this a “deeply alarming backward step on climate action.”
“It’s good to hear that the government thinks there shouldn’t be a ‘blank cheque’ for big tech’s datacentres. But without urgent action, that’s exactly what will happen - the public and the planet will be left to foot the bill for the environmental and social costs of these energy-hungry giants.” Rosa Curling, co-executive director, Foxglove
The standoff leaves the UK charting a narrow path: courting AI investment while managing scarce water and grid capacity. With drought conditions persisting and energy demand rising, the datacentre debate is unlikely to cool before the next election.
