Study challenges UK data-centre job forecasts as construction accelerates

Employment estimates diverge sharply

Britain's planned data centres may directly employ about 10,400 permanent workers, roughly one quarter of the more than 40,000 additional jobs forecast by the technology industry's trade association, according to new research reported by the Guardian. The analysis adds a labour-market test to an infrastructure programme already facing questions about electricity, water and planning.

The environmental thinktank Verdant examined staffing information for 20 projects using planning documents, company accounts, announcements and international comparisons. It estimates that operating data centres already built in Britain created fewer than 4,400 direct jobs. Its calculation excludes the substantially larger but temporary workforce employed during construction.

Verdant measured about 8.6 permanent jobs for each megawatt of claimed power capacity at existing sites and argued that larger future facilities could be less labour-intensive. TechUK defended its estimate that the sector supports 43,500 current jobs and could support another 40,000 by 2035, saying its methodology also captures wider employment effects.

Government disputes the comparison

The government rejected Verdant's jobs-per-megawatt approach, arguing that electricity capacity is not the same as actual consumption and that comparisons with hospitals or factories overlook the broader value of computing infrastructure. Ministers also frame domestic data capacity as a security and sovereignty asset for sensitive health, defence and public-service information.

That strategic case is embedded in government policy. Data centres have been designated critical national infrastructure, while AI Growth Zones are intended to accelerate access to power and planning approvals. The government's delivery plan says the zones could unlock up to £100 billion in investment and create more than 10,000 jobs, with public bodies helping viable projects secure finance.

Planning decisions will test both cases

The dispute is now likely to shape local planning and national energy allocation. Officials must distinguish temporary construction work, permanent operating roles and indirect jobs when assessing promised benefits. Developers will also face demands for clearer forecasts of electricity and water use. Upcoming project approvals will show whether ministers require consistent employment evidence before granting infrastructure support or continue to prioritise computing capacity and national resilience.
