Hiring for technical manufacturing roles is tight, and the numbers make the pressure clear. Skills shortages sit at the top of the list of barriers to growth for manufacturers, cited by 75%, with recruitment named by 36% and talent retention by 32% Barclays Corporate – Skills shortage in UK Manufacturing. When your line needs commissioning cover, you are competing for the same scarce people as everyone else.
The engineering picture is just as stretched. In 2025, 76% of engineering employers struggled to recruit for key roles, with technical and specialist sustainability skills topping the shortage list Institution of Engineering and Technology (IET). That scarcity is exactly what pushes commissioning cover costs up when you leave the hire to the last minute.
The cost of unfilled roles is not abstract. There were 55,000 unfilled long-term vacancies in UK manufacturing in 2025, costing the economy £6bn in lost output every year Make UK – Industrial Strategy Skills Commission Report 2025. Every week a commissioning gap stays open, you carry a share of that lost output on your own balance sheet.
Commissioning cover usually means a specialist: a controls engineer, an automation lead, a process or mechanical commissioning engineer who can bring a new line or upgrade into stable production. These are the exact technical skills in shortest supply, which is why the specialist end of the market sets the pace Institution of Engineering and Technology (IET).
Churn makes the dynamic harder to predict. A striking 79% of UK technical professionals plan to change employers in 2026 Engineering and Technology Jobs (IET) / Rise Technical. High movement means the person you need may be mid-notice or mid-contract, so availability, not just the rate card, shapes what cover actually costs you.
So the real cost drivers are scope, scarcity and timing. A tightly defined commissioning brief with a clear window is far easier to cost than a vague one, because you are pricing a specific set of tasks over a specific period rather than guessing at an open-ended need.
Start with scope, not a number. Write down the systems to be commissioned, the stage the project is at, the standards and sign-offs required, and the handover date. A precise brief turns guesswork into a costable plan and tells every applicant exactly what good looks like.
Then define the skills with real specificity. List the control systems, PLC platforms, safety standards and sector experience you genuinely need, and separate the must-haves from the nice-to-haves. With 76% of engineering employers struggling to recruit for key roles, a sharp specification is what gets you in front of the right people faster Institution of Engineering and Technology (IET).
Set a realistic window and move quickly once you do. Given that 79% of technical professionals expect to move employers in 2026, strong applicants do not stay available for long Engineering and Technology Jobs (IET) / Rise Technical. Line up your interview slots, your decision-maker and your onboarding before you open the role, so a short cover window does not slip and quietly push your costs up.
Finally, protect continuity. Build in a short overlap for handover and keep clear documentation, so the end of the cover period does not reopen the gap you just closed.
