Britain's data-centre build-out has acquired a jobs problem. New analysis from environmental thinktank Verdant estimates that the country's currently planned data centres will directly employ about 10,400 people in permanent operational roles, around a quarter of the 40,000-plus employment figure frequently associated with the sector's expansion.
The comparison needs care. techUK's 2024 report modelled 40,200 additional operational roles by 2035 under a scenario in which UK data-centre capacity growth accelerated from roughly 10% to 15% a year. Verdant examines a set of planned projects and uses observed jobs-per-megawatt evidence. The methodologies are therefore different, but the gap is large enough to matter for infrastructure policy.
Data centres create enormous capacity without enormous headcount
Modern data centres are capital and power intensive. They create construction work, demand specialist engineering and support a wider digital economy, but a completed facility does not necessarily require a workforce proportional to its physical size or electricity consumption. Verdant argues that larger facilities can be particularly labour-light once operational.
techUK's case is broader. Its report estimated that data centres already contributed £4.7 billion in annual GVA, supported 43,500 jobs across the UK economy and generated £640 million in tax revenue. It also argued that more capacity enables digital services and productivity elsewhere. That wider economic contribution is different from the narrower question of how many people work permanently inside new facilities.
Our view: planning decisions need the right metric for the promise being made
British Business Review's view is that policymakers should stop asking one jobs number to carry the entire case for data-centre expansion. If a project is being justified as employment policy, direct permanent jobs and local supply-chain work should be measured transparently. If it is being justified as strategic compute infrastructure, the case should instead quantify capacity, resilience, investment and the economic value of the workloads it enables.
The debate is likely to intensify as AI facilities compete for grid connections, water, land and planning support. The next useful dataset would track each major UK project by megawatts, capital investment, construction employment, permanent employment and grid requirement. That would allow local authorities to compare benefits and costs on the same basis.

| Verdant 2026 analysis | About 10,400 jobs | Direct permanent roles across currently planned projects |
| techUK 2024 growth scenario | 40,200 additional jobs | Operational roles by 2035 under faster capacity growth |
| techUK current contribution estimate | 43,500 jobs | Jobs across the UK economy associated with the sector |
| techUK current GVA estimate | £4.7bn annually | Estimated economic contribution |
Frequently asked questions
How many jobs could planned UK data centres create?
Verdant estimates about 10,400 direct permanent jobs across currently planned projects.
Why does techUK have a much higher number?
techUK modelled 40,200 additional operational jobs by 2035 under a scenario of accelerated capacity growth, so the scope and assumptions are not identical to Verdant's project-based estimate.
Are jobs the only economic benefit of data centres?
No. Supporters also point to digital infrastructure, investment, tax revenue, AI capacity and productivity enabled elsewhere in the economy.
