Summary of the contracting process

National Grid UK Limited procured a framework for civil engineering and building works at electricity substations on the National Grid Electricity Distribution network. Work covers new substation construction and refurbishment, including new or altered buildings, foundations, fencing, drainage, roads, excavation, cable ducts and general building maintenance such as roof repairs, joinery, glazing and gates. It may also involve specialist measures to protect substations from flooding, high winds, humidity and other environmental risks. Works may take place in live substations. The framework is divided into ten geographic lots covering areas of south-west and central England, Wales, and the East and West Midlands, including Redruth, Plymouth, Bristol, Cardiff, Birmingham, Derby and Nottingham.

The procurement is awarded, with 31 suppliers selected across ten lots; contracts were due to be signed on 14 October 2026. The framework contract period runs from 14 October 2026 to 13 October 2027, with a possible extension of up to 12 months. Award values differ by supplier and lot: they range from £3,333,333.34 to £40,000,000 excluding VAT. Awards include A I & Z A Grant Ltd, Alpha Construction Limited, Alun Griffiths (Contractors) Limited, Amalgamated Construction Ltd, A Thomas Plant Hire Limited, Blyth Construction (SW) Ltd, Bridge Civil Engineering Limited, Cambrensis Civil Engineering Limited, and others. The process used a competitive flexible procedure under a selective route. Bidders passed qualification checks, then technical quality carried 70% and commercial evaluation 30%, followed by negotiation.

This award demonstrates sustained demand from National Grid for civil and building contractors able to work across electricity distribution substations, including in operational live environments. Relevant capability includes substation construction and refurbishment, earthworks, foundations, drainage, roads, cable ducting, fencing and building maintenance, as well as specialist resilience work addressing severe weather risks. The buyer selected a broad mix of small and large suppliers, suggesting opportunities were accessible to firms of differing scale, provided they could meet qualification thresholds and deliver safely and reliably across the geographic areas they pursued. A credible competitor would need strong technical proposals, backed by commercial competitiveness, and the capacity to undertake varied civil packages through framework call-offs that may be allocated by mini-competition, portfolio allocation or direct award.
