Balfour Beatty has been awarded the first phase of National Grid's Birkhill Wood substation in East Yorkshire, the company confirmed this week, under National Grid's £8bn Electricity Transmission Partnership.

The contract covers early contractor involvement: detailed design and enabling works to get the site ready before main construction starts in 2027. Birkhill Wood will be a 400kV substation, and its job is to connect three planned North Sea wind farms, Dogger Bank South East, Dogger Bank South West and Dogger Bank D, into the grid. Between them those three sites are expected to generate enough renewable power for around four million homes.

Why it matters

This is one deal within a much bigger pipeline. National Grid and the wider transmission sector are working through roughly £200bn of planned investment over the next decade, and the company has said that scale of spend could support up to 55,000 jobs across the UK by 2030. Birkhill Wood is a visible, funded example of that pipeline turning into actual site work rather than a plan on a slide.

For contractors, it also confirms where the next wave of civils and M&E work is heading: not into new housing, where output keeps falling, but into grid infrastructure tied to offshore wind. Early contractor involvement deals like this one are becoming the normal route in for transmission work, which rewards firms and individuals with a track record in ECI rather than pure lump sum delivery.

What it means for your career

Balfour Beatty says the project will employ around 200 people at peak, including apprentice and graduate roles, once main construction gets going in 2027. That is a live hiring signal for anyone in or near Yorkshire with high-voltage substation, overhead line or grid connection experience: project engineers, planning supervisors and design coordinators with National Grid or DNO-side experience will be in demand well before peak construction, since ECI phases are where the technical teams get built.

More broadly, if your CV is weighted towards housing or general building and you are watching vacancies thin out in that end of the market, energy transmission is one of the few areas still recruiting ahead of need. Quantity surveyors and commercial staff with experience of NEC-based framework call-offs, rather than traditional JCT housebuilding contracts, are particularly well placed, since that is the contract form this whole £8bn partnership runs on. It is worth getting NEC experience onto your CV now if you do not already have it: this kind of work is going to keep coming for years, and firms are hiring for the whole programme, not just this one substation.
