The Cost of an Unfilled Vacancy
On this page
Unfilled vacancies in the UK energy sector significantly impact revenue, project timelines, and workforce morale.
Prolonged hiring leads to overtime costs, stress, and reputational risk. Using data-driven recruitment strategies, such as Astute People’s People Plus and People Solutions, companies can reduce time to hire from 67 to 39 days, safeguarding revenue and securing specialised talent efficiently.
Unfilled vacancies are an often-overlooked drain on resources, affecting finances, operations, and company reputation.
In specialised UK sectors like energy, prolonged vacancies can result in significant lost revenue and project delays.
Matt Dickens, Managing Director at Astute People, provides a data-driven analysis of vacancy costs and solutions for minimising lost revenue.
How Vacancies Drive Costs
- Overtime Payments: Existing staff take on extra work, increasing overtime costs. Energy sector employees average 10.3 hours of overtime weekly, costing businesses billions annually (Personnel Today).
- Increased Employee Stress: 79% of UK workers report stress, often due to understaffed teams, which can increase absenteeism and turnover (Personnel Today).
- Delayed Projects: Absence of critical roles like engineers or project managers can delay projects, resulting in losses from £50,000 to £500,000 per day (Personnel Today).
Calculating the Cost of a Vacancy
Revenue per Employee: Divide total annual revenue by total employees.
Organisational Value Per Day: Divide revenue per employee by annual working days (254 in 2024) to estimate daily revenue loss per vacancy.

Example: £3.5bn revenue ÷ 5,500 employees = £636,364 per employee. £636,364 ÷ 254 days ≈ £2,505/day lost per vacancy.
Long-Term Revenue Impact
Average UK energy sector vacancy fills in 67 days. Using the previous example, this equates to £167,835 lost per vacancy.
Sector-Specific Costs
In energy, technical roles can contribute £100k–£200k per year to revenue. Vacancies in roles like Project Manager or Renewable Energy Engineer can delay multi-million-pound projects and harm reputation.
Reputational Impact
Extended vacancies reduce candidate confidence. Positions advertised for over a month may deter top talent, harming employer brand and future recruitment.
