Every UK firm in a 2026 industry survey reported shortages of qualified mechanical, electrical and plumbing workers. Here is what the evidence says, and five practical steps that keep a data centre or critical building on programme.
What the 2026 numbers say.
of UK respondents report shortages of qualified mechanical, electrical and plumbing workers.
of 112 markets say contractor capacity for data centre projects is tightening or already overstretched.
of UK data centre capacity announced or permitted, on top of about 2.0 GW live across 348 sites.
Labour availability is now the main driver of construction cost increases. In London, data centre work is absorbing a large share of the leading MEP subcontractors, leaving other projects with a smaller pool, and some main contractors are building their own in-house MEP teams. For anyone delivering a data centre, a plant room or a critical building, the risk is no longer only price. It is whether the people are there on the day.

How to keep your programme.
You cannot change the market. You can change how much of your programme depends on it. These are the steps we plan with you from the first conversation.
- Fix the long lead items firstFreeze the ratings of transformers, switchgear and other long lead equipment early and secure a delivery date in writing before anything else.
- Move work into the factorySkids, E-Houses and pre-wired boards arrive assembled and factory tested, so your site team installs and connects instead of building.
- Book commissioning at design stageCommissioning sits at the end of the programme with no float left. Plan the levels, scripts and witness points with the design, not after installation.
- Secure site teams for defined periodsA managed team with its own supervisor, booked for the dates you need, instead of competing for subcontractors week by week.
- Keep records digital from day oneCollect test reports and certificates as the work progresses, so handover is not held up by paperwork at the end.
