2025-03-01
The Bramford–Twinstead Power Transmission Line is a major £363 million National Grid project, designed to upgrade the UK’s high-voltage network and support the country’s transition to renewable energy. Spanning 29km across Essex and Suffolk, the project is a critical piece of infrastructure that will reinforce energy supply and accommodate offshore wind energy.
With major construction work starting in early 2025, the project will require hundreds of skilled workers, contractors, and supply chain partners for civil engineering, electrical installations, steelwork, and groundwork operations. If you’re managing teams on this project, securing local long-stay accommodation is crucial.
