Data centres to be expanded across UK as concerns mount

Data centres, like this one Google is building in Hertfordshire, are becoming a more familiar sight across the UK

The 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.

Data centres are home to powerful servers for things like streaming, online banking and AI tools

Last 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.

United Airlines CEO confirms he approached American Airlines about merger

United Airlines CEO confirms he approached American Airlines about merger

United Airlines CEO Scott Kirby confirmed Monday that he contacted American Airlines about a potential merger, a possibility American rejected.

“I approached American about exploring a combination because I thought we could do something incredible for customers together,” Kirby said in a statement. He said he shared his “big, bold vision” because he was confident it could win regulatory approval.

American rejected the idea and its CEO, Robert Isom, last week said such a merger would be bad for customers and “anticompetitive.”

Kirby had floated the idea to the Trump administration earlier this year, according to people familiar with the matter who weren’t authorized to discuss the private conversation, in hopes that the combination would mean a big global airline to compete with foreign rivals

American declined to comment on Kirby’s Monday statement.

“I was hoping to pitch that story to American, but they declined to engage and instead responded by publicly closing the door,” Kirby said in his statement Monday. “And without a willing partner, something this big simply can’t get done.”

He said that “American’s public comments make it clear that a merger like this is off the table for the foreseeable future” but outlined his vision for a combined airline.

Kirby reiterated that the country has deficit with foreign airlines that fly more than half of the long-haul seats into the U.S., with most of the customers being Americans.

“The combined scale of United and American would be a better way to compete with foreign carriers,” he said.

President Donald Trump said he was against the idea of a combination last week.

“I don’t like having them merge,” he told CNBC’s “Squawk Box” on Tuesday morning. He said he would, however, like someone to buy struggling discount carrier Spirit but he also suggested that the federal government could “help that one out.”

Spirit and the Trump administration are in advanced talks for a rescue package.

This bank CEO let his AI clone handle an earnings call — now he’s signing an OpenAI deal

This bank CEO let his AI clone handle an earnings call — now he’s signing an OpenAI deal

Nearly half an hour into a conference call on Friday to discuss first-quarter results with analysts, Customers Bank CEO Sam Sidhu revealed something unusual — up until that point, he hadn’t actually been speaking.

“The prepared remarks you heard on my behalf today were delivered by my AI clone, not read by me,” Sidhu said, calling it a potential first for a public company earnings call.

The point of the stunt, he said, was to underscore a broader shift happening as Customers Bank, a $25.9 billion asset lender catering to startups and small businesses, embraces artificial intelligence.

Customers Bank has signed a multiyear partnership with OpenAI in which the AI giant will embed engineers at the company to help it automate lending and client onboarding, CNBC has learned exclusively.

The deal is part of Sidhu’s effort to get ahead of other banks in the industry’s race to transform itself using AI agents as a new digital workforce. His strategy hinges on automating core banking processes — slashing loan timelines from weeks to days, for instance — and scaling growth without adding staff at the same pace.

While many bankers have described AI in broad terms like productivity gains, Sidhu is tying it directly to financial targets.

Sidhu told CNBC that the project will improve the firm’s efficiency ratio from about 49 to the low 40s, boosting the bank’s returns starting next year.

The relationship with OpenAI — which has targeted finance as one of its core industries, even hiring former bankers to train its models — will be a symbiotic one for the AI giant, according to the bank CEO.

“We’re going to be co-creating enterprise solutions they could potentially sell to other banks in the future,” Sidhu said. “The goal here is end-to-end, automated agentic led workflow” for lending, deposits and payments.

OpenAI said it was proud to help Customers Bank “as they build a more intelligent operating model that empowers employees, strengthens client service, and sets a new standard for regional banking,” chief revenue officer Denise Dresser said in a statement provided to CNBC.

Always-on workers

The bank expects to roll out AI agents across lending, deposits and payments over the next six to 12 months.

If they succeed, closing a commercial loan will go from taking 30 to 45 days, including underwriting, document collection and legal negotiations, to about seven days, Sidhu said.

Opening accounts for complex commercial clients, which can take more than a day, will be collapsed to under 20 minutes using conversational AI and automated document gathering, he said.

“When you have an autonomous agent, you’re essentially creating a digital worker … and they can work around the clock,” Sidhu said.

Key advantage

While it is a relatively tiny firm compared to the likes of JPMorgan Chase, which has $4.9 trillion in assets, Customers Bank has a key advantage, according to Sidhu, who began his career at Goldman Sachs in 2004. The megabanks have sprawling global operations and far higher complexity and regulatory standards for AI implementation, he said.

“Smaller banks are not going to be expected to have the same level of frameworks as many of the larger banks,” he said. Regulators want community and regional banks “to be able to compete with larger banks.”

The lender already uses AI to write half the firm’s software code and has saved 28,000 hours of work so far, equal to not hiring about 15 full-time employees, he said.

“This is an opportunity for us to potentially slow that hiring … and do more revenue per employee,” he said.

The bank is also exploring entering new businesses that would have been prohibitively expensive to tackle before AI agents. For these AI-native business lines, smaller teams oversee automated systems that handle work previously requiring large numbers of humans, he said.

Unlike typical software licensing agreements, Sidhu said both sides are contributing resources to build new tools together, with OpenAI gaining real-world use cases inside a regulated financial institution.

“It’s going to benefit our investors. It’s going to benefit our customers,” Sidhu said. “Our regulators will hopefully also be happier over time, because they’re going to see us reducing risk as well.”

Spotify teams up with Peloton to launch global fitness content hub


Spotify is increasing its push beyond music and podcasts as the company on Monday announced a new fitness category partnership with Peloton Interactive.

The deal will make more than 1,400 Peloton classes available to Spotify Premium subscribers across most of its global markets, embedding fitness content directly into Spotify’s existing audio and video ecosystem, according to the companies. The offering includes strength training, Pilates, barre, yoga, meditation and more.

“As we continue to forge a path deeper into wellness, our work with Spotify is just our latest move to expand our reach and capture new revenue streams through Peloton’s unmatched experience, content and instruction,” Peloton’s chief commercial officer, Dion Camp Sanders, said in the release. 

Neither company disclosed financial terms, but the partnership is an indication of both companies’ strategic priorities.

For Spotify, the move represents a deeper expansion into wellness, opening up new engagement and monetization pathways beyond its core music and podcast business. Fitness content keeps users on the platform longer and creates opportunities to layer in subscriptions, advertising and creator-driven revenue streams, the company said in a release.

Spotify said more than 150 million fitness playlists are already active globally, with nearly 70% of Premium users reporting they work out monthly.

“Fitness is a natural extension of how people already use Spotify today — to get motivated, recover and reset,” a Spotify spokesperson told CNBC.

Spotify is also building out a broader creator ecosystem around fitness beyond Peloton, working with fitness creators like Yoga With Kassandra, Caitlin K’eli Yoga, Sweaty Studio and Chloe Ting who can monetize through existing tools such as the Spotify partner Program.

For Peloton, the agreement accelerates its pivot away from a hardware-centric model toward scalable, high-margin content distribution. CEO Peter Stern said the deal also builds on his international expansion ambitions.

“Spotify provides a global stage for our instructors, in which they have now the ability to meet hundreds of millions of Spotify Premium subscribers,” Stern told CNBC.

By tapping Spotify’s reach, Peloton is gaining exposure without requiring users to own its equipment or subscribe to its standalone app.
