New analysis suggests planned UK datacentres may directly employ only around 10,400 people — roughly a quarter of the 40,000-plus jobs previously cited by the technology industry — intensifying debate over whether their economic benefits justify their enormous demands on energy, water and land.

Britain’s rapidly expanding datacentre sector is facing fresh scrutiny after new research suggested that the facilities could create far fewer permanent jobs than the technology industry has predicted, challenging one of the central economic arguments used to justify their accelerated development.

An analysis by the environmental thinktank Verdant estimates that datacentres currently planned across the UK are likely to directly employ approximately 10,400 people once operational. That compares with an industry estimate of more than 40,000 additional operational jobs by 2035 promoted by the technology trade body TechUK.

The discrepancy is substantial.

If Verdant’s modelling is correct, Britain could receive only about one quarter of the permanent datacentre jobs that have featured prominently in discussions around investment, planning reform and regional economic development.

The findings arrive as the government continues to promote datacentres as strategically important infrastructure for artificial intelligence, cloud computing and national digital sovereignty. But they also intensify a growing debate over whether the economic return from these extremely resource-intensive facilities has been overstated.

The Employment Question

Datacentres are essential to the modern digital economy.

They house thousands of servers responsible for everything from banking transactions and streaming services to cloud computing, artificial intelligence models and government systems.

Building them can involve enormous investment. Projects costing hundreds of millions or even billions of pounds require construction workers, engineers, electricians and specialist contractors.

The employment picture changes dramatically, however, once construction finishes.

Modern datacentres are highly automated. Their principal purpose is to provide enormous quantities of computing power rather than to accommodate large workforces.

Verdant examined 20 projects using publicly available planning information alongside international employment comparisons. It concluded that existing facilities create approximately 8.6 permanent jobs for every megawatt of installed power capacity.

TechUK’s forecasts, by comparison, imply approximately 43.7 jobs per megawatt, according to the thinktank.

The difference becomes even greater with the emergence of hyperscale facilities designed to support artificial intelligence.

Verdant estimates that some of the largest planned datacentres could employ as few as 1.6 workers per megawatt because automation and scale allow enormous computing facilities to function with relatively small permanent teams.

That matters because future datacentres are likely to be significantly larger and more energy-intensive than many facilities currently operating in Britain.

Industry Forecasts Under Pressure

TechUK has estimated that the sector could create 40,200 additional direct operational jobs between 2025 and 2035, alongside 18,200 direct construction jobs over the same period.

The government has repeatedly cited those estimates when discussing the potential economic contribution of datacentre investment.

In a parliamentary response in July, however, the Department for Business and Trade acknowledged that it had not produced its own independent estimate of the number of permanent jobs likely to result from major datacentre investment and instead referenced TechUK’s projections.

That admission gives the Verdant analysis added political significance.

If ministers are relying heavily on industry calculations when assessing employment benefits, critics argue that planning and infrastructure decisions may be based on assumptions that have not been independently tested.

TechUK rejects that interpretation and has challenged Verdant’s methodology, arguing that the thinktank does not adequately capture employment across the wider datacentre ecosystem.

Supporters of the industry also point out that direct employment inside individual facilities represents only one component of their economic impact.

Datacentres require electrical infrastructure, cooling systems, cybersecurity specialists, maintenance contractors, network engineers and sophisticated supply chains. Their presence can also support cloud computing companies, AI businesses and other technology industries that depend on access to computing capacity.

The disagreement is therefore partly about what should count as a datacentre job.

Construction Jobs Versus Permanent Jobs

One of the most important distinctions concerns temporary construction employment.

A major datacentre can employ hundreds or even thousands of workers while it is being built.

Those jobs can last several years and provide significant economic activity for local suppliers.

Once operational, however, employment often drops sharply.

A highly automated facility occupying an enormous industrial site may ultimately require only a relatively small workforce to operate servers, security systems, electrical infrastructure and cooling equipment.

Verdant’s analysis focuses primarily on permanent operational employment rather than temporary construction roles.

That distinction has become increasingly important because communities considering major datacentre developments are often presented with large headline job figures that may combine temporary and permanent employment.

For local authorities making decisions over land use and infrastructure, the difference can be critical.

A project producing several thousand temporary construction jobs but fewer than 200 permanent positions represents a very different long-term economic proposition from a manufacturing facility employing thousands of people for decades.

The Energy Trade-Off

The employment debate is particularly sensitive because datacentres consume extraordinary amounts of electricity.

Rapid growth in artificial intelligence has increased power requirements dramatically, as training and operating large AI models requires vast networks of specialised processors running continuously.

The United Nations Economic Commission for Europe warned this week that global datacentre electricity use could rise from approximately 485 terawatt-hours in 2025 to about 950 TWh by 2030 — roughly 3% of total global electricity demand.

Britain is attempting to attract a significant share of that infrastructure.

Hundreds of facilities are either planned or awaiting connections to the electricity network, creating concerns about whether datacentre expansion could compete with housing, manufacturing and other industries for limited grid capacity.

The government argues that investment in electricity generation and transmission will allow Britain to support both datacentres and wider electrification.

Critics remain unconvinced.

Their concern is increasingly framed as an opportunity-cost question: if enormous quantities of electricity, land and infrastructure are allocated to datacentres, what economic benefit does Britain receive in return?

If the employment return is significantly smaller than previously suggested, that calculation becomes harder to defend.

Water and Environmental Pressure

Electricity is not the only concern.

Datacentres can require large quantities of water for cooling, depending on the technologies used.

Communities considering major projects have raised concerns about water availability, noise, land use and local environmental impacts.

Opposition has become particularly visible in Scotland, where campaigners have called for a temporary pause on new datacentre development while the government assesses their environmental effects.

Hundreds of protesters gathered outside the Scottish parliament earlier this month over proposals that include major facilities in areas with substantial renewable-energy resources.

Campaigners argue that communities are being asked to absorb significant environmental and infrastructure costs without receiving comparable employment benefits.

Industry representatives respond that newer facilities are becoming more efficient and that developers increasingly use closed-loop cooling systems, renewable power agreements and other technologies designed to reduce environmental impact.

Government Sees Strategic Infrastructure

The government nevertheless regards datacentres as far more than employment projects.

In 2024, Britain designated datacentres as critical national infrastructure, placing them alongside sectors such as energy and water because of their importance to economic activity and national security.

Ministers have subsequently linked datacentre expansion directly to their ambition to make Britain a leading artificial-intelligence economy.

Government policy includes AI Growth Zones intended to accelerate the development of computing infrastructure in areas including the North East, Oxfordshire, Wales and Scotland.

Officials argue that Britain cannot become a major AI power without domestic computing capacity.

Cloud computing, advanced research, defence systems, financial services and artificial intelligence increasingly depend on access to large amounts of secure processing capacity.

The government therefore views datacentres not simply as workplaces but as enabling infrastructure.

That distinction is important.

A power station, railway or fibre-optic network may employ relatively few people directly while supporting economic activity worth far more than its payroll.

Datacentre advocates argue the same logic applies to computing infrastructure.

The Wider Digital Economy

Government data underlines the broader significance of the technology sector.

Britain’s digital and technology industries employed approximately 2.6 million people in 2023 and generated around £207 billion in gross value added, according to Skills England.

Employment in 30 priority digital occupations could increase by approximately 239,000 jobs between 2025 and 2035, although the government acknowledges considerable uncertainty because AI itself may reduce demand for some roles.

This creates an important distinction between datacentres and the industries they support.

A datacentre may employ relatively few workers directly while enabling hundreds of AI or software companies to operate.

The challenge is proving that such benefits will actually occur locally rather than simply supporting multinational technology companies whose economic activity is distributed internationally.

That question has become increasingly important as local authorities grant planning permission for large facilities.

Who Really Benefits?

Recent scrutiny has also exposed another gap in government knowledge.

A Freedom of Information request reported earlier this month showed that ministers did not have comprehensive information about what some of Britain’s largest datacentres were being used for or which companies ultimately relied on them.

That has strengthened calls for greater transparency.

Critics argue that if governments are prioritising datacentres in planning and electricity-grid decisions, policymakers should be able to demonstrate what economic or strategic benefits individual projects provide.

A facility supporting British universities, AI startups or critical government infrastructure may present a different public-interest case from one primarily serving overseas digital services.

The government has resisted calls for a moratorium, arguing that restricting development would damage investment, employment and national security.

A Debate About Value, Not Technology

The controversy therefore does not fundamentally concern whether Britain needs datacentres.

Almost every modern economy does.

The more difficult question is how many Britain should build, where they should be located and what public benefits should be required in return for access to scarce electricity, land and planning capacity.

Verdant’s employment analysis challenges one of the simplest arguments previously used in favour of expansion: that datacentre construction automatically produces large numbers of permanent local jobs.

The industry disputes that conclusion and points instead to indirect employment, productivity, investment and strategic importance.

Both sides may contain elements of truth.

Datacentres can be economically important while remaining relatively poor generators of direct employment.

That distinction is becoming increasingly important as Britain commits billions of pounds of infrastructure capacity to the artificial-intelligence economy.

For policymakers, the central question is no longer simply whether datacentres create jobs.

It is whether the combination of jobs, investment, technological capability and national resilience they provide is sufficient to justify the enormous quantities of energy, water and land they consume.

As Britain’s AI infrastructure race accelerates, that calculation is likely to become one of the most important economic and planning debates of the decade.
