Competitive salary + benefits

I’m supporting an established energy infrastructure business looking for an Estimator to join its tendering team, working on HV projects across the industrial, renewables and utility sectors.

Covering projects typically between 11kV and 132kV, you’ll take ownership of estimates from initial enquiry through to tender submission and handover. The work includes substations, grid connections, cabling and associated electrical equipment.

This would suit someone who enjoys getting into the technical detail, challenging costs and working closely with engineering and delivery teams to build competitive, achievable bids.

The role
  • Build estimates from first principles, covering equipment, materials, labour, subcontractors, preliminaries and risk.
  • Review drawings, single line diagrams and specifications to establish scope, exclusions and assumptions.
  • Obtain and assess supplier and subcontractor quotations.
  • Identify project risks, programme constraints and opportunities to improve costs.
  • Work with Design, Engineering, Procurement and Operations throughout the tender process.
  • Prepare tender submissions, respond to queries and support handover to the delivery team.
What you’ll bring
  • Proven experience estimating HV projects within an ICP, DNO, IDNO, OEM solutions or principal contractor environment.
  • Experience pricing 33kV and/or 132kV substations, connections, cabling or similar works.
  • The ability to turn technical drawings and specifications into a detailed cost model.
  • Working knowledge of G81, NERS/ICP requirements and DNO/IDNO specifications.
  • Strong Excel skills and confidence managing multiple tenders at different stages.
  • The ability to explain your estimates clearly and challenge assumptions constructively.

An electrical engineering qualification is desirable but equivalent practical experience also considered. Experience with BESS, solar, data centre, industrial or rail connections would be useful.

What’s on offer
  • 26 days’ annual leave plus bank holidays.
  • Enhanced pension and life assurance.
  • Health and wellbeing support.
  • Enhanced family leave policies.
  • Ongoing training and professional development.
