Data centres to be expanded across UK as concerns mount
Getty ImagesThe number of data centres in the UK is set to increase by almost a fifth, according to figures shared with BBC News.
Data centres are giant warehouses full of powerful computers used to run digital services from movie streaming to online banking – there are currently an estimated 477 of them in the UK.
Construction researchers Barbour have analysed planning documents and say that number is set to jump by almost 100, as the growth in artificial intelligence (AI) increases the need for processing power.
The majority are due to be built in the next five years.
However, there are concerns about the huge amount of energy and water the new data centres will consume.
Some experts have warned it could drive up prices paid by consumers.
More than half of the new data centres would be in London and neighbouring counties.
Many are privately funded by US tech giants such as Google and Microsoft and major investment firms.
A further nine are planned in Wales, one in Scotland, five in Greater Manchester and a handful in other parts of the UK, the data shows.
While the new data centres are mostly due for completion by 2030, the biggest single one planned would come later – a £10-billion AI data centre in Blyth, near Newcastle, for the American private investment and wealth management company Blackstone Group.
It would involve building 10 giant buildings covering 540,000 square meters – the size of several large shopping centres – on the site of a former Blyth Power Station.
Works are set to begin in 2031 and last for more than three years.
Microsoft is planning four new data centres in the UK at a total cost of £330 million, with an estimated completion between 2027 and 2029 – two in the Leeds area, one near Newport in Wales, and a five-storey site in Acton, north west London.
And Google is building two data centres, totalling £450m, spread over 400,000 sq m in north east London in the Lee Valley water system.
By some analyses, the UK is already the third-largest nation for data centres behind the US and Germany.
The government has made clear it believes data centres are central to the UK’s economic future – designating them critical national infrastructure.
But there are concerns about their impact, including the potential knock-on effect on people’s energy bills.
It is not known what the energy consumption of the new centres will be as this data is not included in the planning applications, but US data suggests they are can be considerably more powerful than older ones.
Dr Sasha Luccioni, AI and climate lead at machine learning firm Hugging Face, explains that in the US “average citizens in places like Ohio are seeing their monthly bills go up by $20 (£15) because of data centres”.
She said the timeline for the new data centres in the UK was “aggressive” and called for “mechanisms for companies to pay the price for extra energy to power data centres – not consumers”.
According to the National System Operator, NESO, the projected growth of data centres in Great Britain could “add up to 71 TWh of electricity demand” in the next 25 years, which it says redoubles the need for clean power – such as offshore wind.
‘Fixated with sustainability’
There are also growing concerns about the environmental impact of these enormous buildings.
Many existing data centre plants require large quantities of water to prevent them from overheating – and most current owners do not share data about their water consumption.
Stephen Hone, chief executive of industry body the Data Centre Alliance, says “ensuring there is enough water and electricity powering data centres isn’t something the industry can solve on its own”.
But he insisted “data centres are fixated with becoming as sustainable as possible”, such as through dry-cooling methods.
Such promises of future solutions have failed to appease some.
In Potters Bar, Hertfordshire, residents are objecting to the construction of a £3.8bn cloud and AI centre on greenbelt land, describing the area as the “lungs” of their home.
And in Dublin there is currently a moratorium on the building of any new data centres because of the strain existing ones have placed on Ireland’s national electricity provider.
In 2023 they accounted for one fifth of the country’s energy demand.
Getty ImagesLast month, Anglian Water objected to plans for a 435 acre data centre site in North Lincolnshire. The developer says it aims to deploy “closed loop” cooling systems which would not place a strain on the water supply.
The planning documents suggest that 28 of the new data centres would be likely to be serviced by troubled Thames Water, including 14 more in Slough, which has already been described as having Europe’s largest cluster of the buildings.
The BBC understands Thames Water was talking to the government earlier this year about the challenge of water demand in relation to data centres and how it can be mitigated.
Water UK, the trade body for all water firms, said it “desperately” wants to supply the centres but “planning hurdles” need to be cleared more quickly.
Ten new reservoirs are being built in Lincolnshire, the West Midlands and south-east England.
A spokesperson for the UK Government said data centres were “essential” and an AI Energy Council had been established to make sure supply can meet demand, alongside £104bn in water infrastructure investment.

New Delhi: Several crucial deadlines have been extended in December 2025, including ITR for tax audit cases, ITR filing and PAN and Aadhaar linking. These deadlines will be crucial in ensuring that your financial affairs operate smoothly in the months ahead.
Here is a quick rundown of the important deadlines for December to help you stay compliant and avoid last-minute hassles.
ITR deadline for tax audit cases
The Central Board of Direct Taxes has extended the due date of furnishing of return of income under sub-Section (1) of Section 139 of the Act for the Assessment Year 2025-26 which is October 31, 2025 in the case of assessees referred in clause (a) of Explanation 2 to sub-Section (1) of Section 139 of the Act, to December 10, 2025.
Belated ITR filing deadline
A belated ITR filing happens when an ITR is submitted after the original due date which is permitted by Section 139(4) of the Income Tax Act. Filing a belated return helps you meet your tax obligations, but it involves penalties. You can only file a belated return for FY 2024–25 until December 31, 2025. However, there will be a late fee and interest charged.
PAN and Aadhaar linking deadline
The Income Tax Department has extended the deadline to link their PAN with Aadhaar card to December 31, 2025 for anyone who acquired their PAN using an Aadhaar enrolment ID before October 1, 2024. If you miss this deadline your PAN will become inoperative which will have an impact on your banking transactions, income tax return filing and other financial investments.

Getty ImagesSouth Korea’s largest online retailer, Coupang, has apologised for a massive data breach potentially involving nearly 34 million local customer accounts.
The country’s internet authority said that it is investigating the breach and that details from the millions of accounts have likely been exposed.
Coupang is often described as South Korea’s equivalent of Amazon.com. The breach marks the latest in a series of data leaks at major firms in the country, including its telecommunications giant, SK Telecom.
Coupang told the BBC it became aware of the unauthorised access of personal data of about 4,500 customer accounts on 18 November and immediately reported it to the authorities.
But later checks found that some 33.7 million customer accounts – all in South Korea – were likely exposed, said Coupang, adding that the breach is believed to have begun as early as June through a server based overseas.
The exposed data is limited to name, email address, phone number, shipping address and some order histories, Coupang said.
No credit card information or login credentials were leaked. Those details remain securely protected and no action is required from Coupang users at this point, the firm added.
The number of accounts affected by the incident represents more than half of South Korea’s roughly-52 million population.
Coupang, which is founded in South Korea and headquartered in the US, said recently that it had nearly 25 million active users.
Coupang apologised to its customers and warned them to stay alert to scams impersonating the company.
The firm did not give details on who is behind the breach.
South Korean media outlets reported on Sunday that a former Coupang employee from China was suspected of being behind the breach.
The authorities are assessing the scale of the breach as well as whether Coupang had broken any data protection safety rules, South Korea’s Ministry of Science and ICT said in a statement.
“As the breach involves the contact details and addresses of a large number of citizens, the Commission plans to conduct a swift investigation and impose strict sanctions if it finds a violation of the duty to implement safety measures under the Protection Act.”
The incident marks the latest in a series of breaches affecting major South Korean companies this year, despite the country’s reputation for stringent data privacy rules.
SK Telecom, South Korea’s largest mobile operator, was fined nearly $100m (£76m) over a data breach involving more than 20 million subscribers.
In September, Lotte Cards also said the data of nearly three million customers was leaked after a cyber-attack on the credit card firm.
