The primary focus is on construction and refurbishment activities across various regional zones in the United Kingdom, including areas like the South West, East Midlands, South Wales, and West Midlands. The tender is currently active, and potential suppliers are encouraged to submit expressions of interest by 12 May 2026. This project falls within the critical industry category of substation construction work. The procurement method is a selective, competitive flexible procedure with multiple evaluation stages, starting from qualification to request for proposal (RFP) and negotiation phases. The contract is expected to commence on 22 June 2026. This tender provides substantial growth opportunities for businesses specialising in civil engineering, construction, and maintenance within electrical substations. Companies with expertise in handling "live" substation environments and employing specialist techniques for environmental protection will find this project particularly suitable. With a gross contract value of £48 million, it is an attractive prospect for firms capable of delivering high-quality work on a large scale. Potential bidders should have the capability to manage flexible procurement strategies, such as mini-competitions and direct awards, which are part of the call-off procedures under the framework. Participation in such a significant infrastructure development project can elevate a company's standing and open avenues for similar future works. ## Notice Works under the Framework comprises of civil engineering & building work associated with the construction of new and refurbishment of existing electricity substation sites within NGED's electrical distribution network.
