Verdant challenges the jobs case for UK data-centre expansion

Verdant estimates that the UK’s existing and planned data-centre estate would support about 10,400 direct jobs, far below industry projections. But the apparent gap also reflects a dispute over what should count: permanent on-site roles, wider economic employment, or the strategic value of domestic computing capacity.
Verdant estimates that the UK’s existing and planned data-centre estate would support roughly 10,400 direct jobs.
The estimate is not a count of construction work or of jobs at companies that use computing capacity.
TechUK says the sector supports 43,500 jobs now and could support 40,000 more by 2035; the two claims use different scopes and methods.
An environmental thinktank has challenged the employment case for Britain’s data-centre build-out, estimating that the existing and proposed estate would support about 10,400 direct jobs. The figure is an estimate of the permanent people needed to operate and maintain facilities, rather than a count of construction workers or a measure of the economic activity that computing may enable.
That distinction is the substance of the dispute, not a footnote. Ministers have made AI data centres critical national infrastructure, while the industry argues that domestic computing capacity has economic, security and sovereignty value beyond a site’s payroll. Verdant’s case is that those wider arguments should be made explicitly, rather than treating a large employment number as settled evidence for every proposed development.
Verdant, a London-founded environmental thinktank, based its September 9 briefing on 20 projects with public staffing information, including planning applications, company accounts and press releases, as well as international comparisons. It says existing UK data centres support roughly 4,400 direct jobs.
The group applies that evidence to developments in the pipeline and describes the resulting 10,400 figure as total direct jobs nationally. Contemporary coverage of the research similarly characterises the projected shortfall as one in direct jobs. Neither formulation makes 10,400 an observed outcome for sites that have not yet been built.
Five technology groups have accumulated an estimated $3.2 trillion in future purchase and lease commitments. Filings show the funding pressure, but broad spending categories, long payment schedules and a methodology change limit what the total says about AI debt and growth.

Verdant’s comparison with TechUK rests on a jobs-per-megawatt calculation. It puts the existing estate at about 8.6 direct jobs per megawatt of energy consumed, against 43.7 jobs per megawatt in TechUK’s projections. It argues that projects still in planning are much bigger and could need as few as 1.6 permanent roles per megawatt.
Those are modelled ratios, not a measure of every economic effect of a data centre. The briefing explicitly excludes temporary construction employment and does not estimate jobs at businesses that rely on the facilities’ computing capacity. It also argues that its result makes jobs an inadequate primary rationale for further rapid build-out; that conclusion is the thinktank’s policy judgment, not a finding shared by the government or the industry.

The comparison is not like for like
TechUK, the technology-industry lobby group, says the UK data-centre industry currently supports 43,500 jobs and could support another 40,000 by 2035. In its response, carried in the report on Verdant’s analysis, its spokesperson said those estimates use industry data and standard economic-impact assessment techniques and are based on a published methodology.
That wording is broader than a tally of permanent staff inside data-centre buildings. It means 10,400 and 40,000 should not be treated as rival answers to a single, precisely defined question. The gap also needs another qualification: Verdant says the existing estate supports about 4,400 direct jobs rather than 24,300 claimed by industry, while TechUK’s response describes the industry as supporting 43,500 jobs now. The retained accounts do not reconcile those differently scoped current-employment figures.
The government has also challenged Verdant’s chosen denominator. A spokesperson said the report used a “deeply misleading” jobs-per-megawatt metric, made false comparisons with hospitals and schools, and appeared to confuse electricity capacity with actual consumption. Verdant replies that it used the capacity technology companies say they need, which it says can still displace other uses even when a finished site does not consume all of it.
This is a real methodological disagreement. The capacity companies say they need and electricity actually consumed are not interchangeable quantities; nor is a permanent operating payroll the same measure as an economic-impact estimate. The retained reporting does not provide enough underlying project-level data to independently choose between the multipliers.
Jobs are not the government’s only stated rationale
The Labour government has classified AI data centres as critical national infrastructure, a step intended to speed planning. Kanishka Narayan, the AI minister appointed to Andy Burnham’s cabinet, has argued for rapidly expanding capacity partly on sovereignty grounds.
That case has drawn a different challenge from the Green party in England and campaigners in Scotland, who have opposed the pace of development. Verdant’s recommendations are a pause until a national framework can demonstrate need and use cases, a wider public discussion, and firmer planning rules on access to constrained electricity and water.
The government rejects a pause, saying it would send investment and jobs abroad and leave Britain dependent on overseas computing for sensitive processing. That does not resolve the employment estimate; it states a different basis for making the infrastructure choice.
What would settle the policy question
The next useful test is not a single headline multiplier. A planning or national-infrastructure case should separately disclose permanent operating roles, temporary construction work, indirect or induced employment, the capacity sought, the electricity expected to be used, and the specific public or commercial purpose of the computing.
Until those categories are published on compatible bases, the most defensible conclusion is limited: Verdant has challenged the claim that permanent on-site jobs alone justify a rapid build-out. Whether the projects warrant priority for grid capacity, water and planning consent depends on the wider benefits that government and developers can substantiate.
