30 Second Briefing
Trant Engineering has secured a place on National Grid’s new dynamic market framework for major civil engineering works at substations, joining nine contractors in the Major Civils workstream for projects over £5m alongside BAM Nuttall, Costain, Galliford Try, Laing O’Rourke and Skanska. The framework is intended to streamline procurement and accelerate delivery of substation construction and upgrade schemes across the UK transmission network. Trant’s selection is based on performance in live, highly regulated substation environments, with a focus on safety, technical assurance and collaborative delivery on critical grid assets.
Technical Brief
- Major Civils workstream covers individual substation civils packages valued above £5m per project.
- Framework spans both new-build substation construction and upgrade works across National Grid’s transmission network.
- Thirteen contractors are prequalified overall, with only nine, including Trant, eligible for Major Civils lots.
- Trant’s scope will involve working in live, energised substation environments under stringent electrical safety controls.
- National Grid’s “dynamic market” structure allows contractors to be added or removed as performance and needs change.
- Selection criteria emphasised technical assurance processes and quality management in highly regulated energy infrastructure settings.
- Long-standing Trant–National Grid relationship is based on repeat delivery under tight operational and outage constraints.
Our Take
In our infrastructure coverage, Trant’s recent AMP8 water framework work in the South West suggests the company is pivoting towards long‑horizon framework income across regulated utilities, reducing reliance on one‑off EPC contracts.
National Grid’s parallel moves on high‑voltage cable frameworks and dynamic line rating upgrades indicate that substation framework members will likely see a steady pipeline of reinforcement and connection jobs as the UK transmission network is uprated rather than simply expanded.
