EHV Electrical Estimator

The Company

Our client are an innovator within the provision of integrated utility infrastructure solutions. Specialising in delivering technically complex, large-scale infrastructure for energy and communications clients across the UK and Europe, they are backed by strong private equity investment and over 25 years of operational excellence.

As EHV Electrical Estimator, you’ll be responsible for preparing robust, accurate, first-principles cost estimates for projects at 132kV and above. You’ll interpret technical drawings and employer specs to develop detailed cost models for primary plant, secondary systems, and associated civil and commissioning works. Your estimates will help drive competitive tenders, frameworks and project approvals.

Estimating & Cost Development

Develop first-principles cost estimates for EHV substation components: transformers, switch gear (AIS/GIS), protection systems, busbars, etc.

Build accurate cost models for materials, plant, labour, prelims, and indirects.

Factor access, site conditions, outages, and productivity rates into your methodology.

Produce traceable and auditable pricing schedules aligned to project scope.

Interpret layout drawings, SLDs, specs, and ERs.

Liaise with engineering and construction to understand buildability and assumptions.

Evaluate supplier/subcontractor quotes and align with technical requirements.

Identify exclusions, value‑engineering options, and risk assumptions.

Risk, Allowances & Governance

Maintain clear estimate back‑up, risk registers, and audit trails.

Apply suitable contingencies, escalations, and allowances based on uncertainty.

Support internal reviews and governance processes.
