Britain does not have enough water for more data centres: Industry says Labour’s AI growth plans do not ‘make a single mention’ of water and are ‘fatally flawed’
The UK's water industry has warned that Britain lacks sufficient water supplies to support the government's planned expansion of data centres, arguing that Labour's AI growth strategy is "fatally flawed" because it fails to account for water usage. Industry figures say the policy does not "make a single mention" of water, despite data centres requiring vast quantities for cooling servers, raising concerns that the push to position the UK as an AI leader could clash with existing pressures on the nation's water resources.
The warning comes as the government pursues an aggressive AI infrastructure agenda, encouraging investment in new data centres to power the technology sector, while water companies and industry bodies highlight that supply networks are already under strain from population growth, ageing infrastructure and climate pressures. Critics argue that without addressing water consumption directly in planning, new data centre developments risk exacerbating shortages or facing local resistance, undermining the feasibility of Labour's broader AI growth ambitions.
In short
- Water industry says UK lacks water for more data centres
- Labour's AI growth plan omits water considerations entirely
- Critics call the strategy "fatally flawed" amid supply strain
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
The government's AI growth strategy is sound because data centre expansion remains compatible with UK prosperity and the water sector has viable solutions at its disposal. Proponents argue that technological innovation in cooling systems, water recycling technologies, and operational efficiency can substantially reduce consumption; moreover, the economic gains from AI leadership could fund infrastructure upgrades that benefit the entire water system. Rather than abandoning growth ambitions, coordination between government and water companies can ensure data centres are sited strategically and built to the highest efficiency standards.
The case against
The water industry's warning reflects a legitimate physical reality: the UK faces acute water stress now, with ageing infrastructure, population growth, and climate pressures already straining supplies. Data centres are exceptionally water-intensive operations requiring enormous cooling capacity, and the government's silence on water in its AI strategy is not a procedural oversight but a dangerous blind spot. Without binding water commitments and local supply assessments built into planning from the outset, new data centre projects will inevitably collide with scarcity, forcing delays, inflating costs, and provoking community opposition that could ultimately undermine the entire agenda.
Explained simply
Data centres are large buildings that house the computers and storage systems behind online services and artificial intelligence. Their servers produce heat, so some centres use water in cooling systems, though the amount varies by design and location.
The UK government wants to expand AI and attract investment in the infrastructure it needs. Water companies and industry groups are responsible for supplying water and have raised concerns about meeting future demand amid population growth, older networks and changing climate conditions.
Where new data centres are built can affect local water demand, so planning decisions may involve both technology investment and water supply. The issue matters because reliable water access could shape which projects are practical and how the UK develops its AI infrastructure.
