Market Context — Hiring Trends

The UK BESS and power infrastructure market remains highly competitive, driven by grid upgrades, storage deployment, and continued investment in flexible energy assets. Demand is strongest for Grid Connection Engineers, HV Design Engineers, Protection Engineers, and BESS Project Managers, with experienced candidates consistently commanding premiums above advertised rates.

Projects are moving faster than the available talent pool. Employers are prioritising candidates with hands-on grid, HV, and energy storage experience, while hiring timelines are extending, particularly for roles requiring HV authorisation, grid expertise, or project delivery experience. Shortlist quality and speed to hire are now critical.

This imbalance is reflected in hiring timelines. Specialist engineering roles are increasingly taking 30–50% longer to fill compared to pre-2023 benchmarks, particularly where HV experience, grid expertise, or regulatory sign-off is required. At the same time, candidates are becoming more selective, often evaluating multiple offers before accepting.

The market trend is clear: projects are moving faster than the talent pool. Employers are prioritising candidates with hands-on grid, HV, and energy storage experience, while hiring times are lengthening and shortlist quality matters more than ever. For Aviserv, this is a specialist market where speed, technical understanding, and market knowledge make the difference between filling a role and missing the hire.

‍

Aviserv focuses specifically on these markets, allowing us to:

●     Identify qualified candidates faster through targeted networks, not broad job ads

●     Accurately benchmark salaries based on live hiring activity, not outdated surveys

●     Reduce time-to-hire by prioritising pre-qualified, technically relevant candidates

●     Deliver higher-quality shortlists aligned to both technical and commercial requirements

‍

The result is a more efficient hiring process, fewer interviews, faster decisions,and better long-term hires.

Market Intelligence & Insights

The UK BESS and power infrastructure hiring market continues to operate under sustained supply constraints, with demand for grid and HV skillsets significantly outpacing available talent.

• Salary inflation is being driven by project demand, not market cycles
  Grid and BESS-related roles have seen 10–20% increases in accepted offers vs advertised salaries, particularly on developer-side projects where delivery timelines are fixed.
  ‍
• Time-to-hire has increased materially
  Specialist roles are taking 30–50% longer to fill compared to pre-2023 levels, with delays most acute in Grid Connection, Protection, and HV Authorised Engineer positions.
  ‍
• The grid and HV talent market is structurally split
  There are two distinct hiring markets:
  • Utilities and legacy infrastructure: £45k–£60k
  • Renewable developers and private infrastructure: £65k–£90k+
    Most public salary data reflects the lower band, while actual hiring outcomes sit in the upper range.
    ‍
• BESS project delivery roles are the fastest-moving segment
  Project Managers and delivery-side engineers are seeing the highest upward pressure on salaries, with experienced candidates often managing multiple offers simultaneously due to limited supply.
  ‍
• Candidate behaviour has shifted
  Shortlisted candidates are now typically engaged in 2–3 concurrent processes, with acceptance decisions driven by project exposure, delivery ownership, and long-term pipeline visibility — not just salary.
  ‍
• Published salary data is consistently behind the market
  Most salary benchmarks reflect advertised ranges, which lag real hiring conditions by 6–12 months. Live market data shows that final offers are regularly agreed above published ranges to secure critical hires.
