When a business needs skills it does not currently have, the conversation usually comes down to two options: develop existing employees or recruit someone who already has the experience. Upskilling can appear to be the more affordable choice, particularly when recruitment involves advertising, interviews, onboarding and additional salary costs. Hiring, however, can bring expertise into the business that would take considerable time to develop internally.
For employers in construction, engineering, manufacturing, automotive and logistics, this decision has practical consequences. A missing skill can delay a project, reduce workshop capacity, affect production quality or prevent a business from accepting new work. The most cost-effective approach therefore depends on more than the price of a training programme or a recruitment fee. It depends on what the business needs, how quickly it needs it and whether its existing workforce has the capacity to deliver.
The strongest starting point is to distinguish between a shortage of skills and a shortage of people. Training can help employees become more capable and productive, but it cannot always provide the additional working hours a growing business requires. Equally, recruiting more people will not necessarily solve a problem caused by outdated processes or a lack of development within the existing team.
Understanding what the business actually needs
Before comparing costs, employers need a clear picture of the gap they are trying to close. An engineering company introducing new design software may already have experienced employees who understand its products, customers and technical requirements. In that situation, targeted training could be a sensible investment because the underlying expertise is already present.
A manufacturer adding a second shift faces a different challenge. Existing employees might benefit from further training, but the business still needs enough people to operate equipment, supervise production and maintain quality across additional hours. Upskilling may support the expansion, yet recruitment is likely to remain necessary.
There is also a distinction between upskilling and reskilling. Upskilling builds on someone’s existing capabilities, such as helping a vehicle technician develop more advanced diagnostic skills. Reskilling prepares someone for a substantially different role. Both can create value, but their costs, timescales and likelihood of success can differ significantly. Treating every development opportunity as a short course risks underestimating the investment required.
These questions are increasingly relevant to workforce planning. In the World Economic Forum’s Future of Jobs Report 2025, 63% of surveyed employers identified skills gaps as a major barrier to business transformation between 2025 and 2030. The same report found that 85% planned to prioritise upskilling while 70% expected to hire people with new skills. Those overlapping responses suggest that employers see a role for both approaches.
What upskilling really costs
The visible cost of upskilling is usually straightforward: course fees, assessment charges, learning materials and any necessary equipment. The wider cost is less obvious. Employees need time to learn, practise and demonstrate competence. During that period, their availability for normal duties may fall, so colleagues, supervisors or temporary staff may need to provide cover.
Internal training also draws on the time of experienced employees. A senior technician mentoring a colleague is making a valuable contribution, but those hours are unavailable for other work. If that technician already handles complex repairs, quality checks or urgent customer problems, the business needs to account for the effect on capacity.
There may also be a period between completing training and working confidently without supervision. A qualification or attendance certificate does not automatically mean someone can handle every real-world situation associated with a role. Employers should budget for supported practice, feedback and appropriate assessment, particularly where mistakes could affect safety, quality or expensive equipment.
This does not make upskilling poor value. It makes accurate planning essential. A training programme that appears inexpensive can become costly if the business has underestimated the cover required or assumed the employee will become fully productive immediately. A more substantial programme may offer better value if it produces a clearly defined capability that the business can use consistently.
When developing existing employees offers better value
Upskilling is particularly attractive when employees already have a strong foundation in the work. They understand the organisation’s systems, know its customers and have established relationships with colleagues. Building on that knowledge can reduce some of the adjustment involved in bringing someone new into the business.
Consider an experienced production operative learning to set up equipment they already use every day. Their familiarity with the machinery, common faults and quality requirements may provide a useful starting point. Similarly, an established team member preparing for a supervisory role already understands the working environment, although they will still need support to develop management skills.
Development can also strengthen employees’ reasons to stay. When people can see a credible route towards greater responsibility, better pay or more interesting work, they may be more willing to build their careers with the organisation. That benefit is not guaranteed, but it becomes more plausible when training is connected to real opportunities rather than simply adding duties to an unchanged role.
The return can extend beyond one individual. Training several employees to perform an important task reduces dependence on a single person and can make it easier to manage holidays, absence or changes in demand. For a business where work regularly stops because only one employee can resolve a particular issue, broader capability may be a valuable investment.
Where upskilling reaches its limits
Development works best when the distance between someone’s current ability and the required standard is manageable. An employee with relevant experience may be able to acquire an additional skill within a realistic timeframe. Building years of specialist judgement from a limited starting point is a different proposition.
Employers also need to consider whether the employee wants the proposed career path. A strong technical performer may have little interest in supervising a team. Someone who enjoys their current responsibilities may not want to move into a completely different discipline. Development decisions are more likely to succeed when they reflect both business requirements and the individual’s interests.
Capacity is another constraint. If a team is already struggling to complete its workload, expecting employees to train alongside their normal responsibilities can create further pressure. Without protected learning time or suitable cover, the business risks rushed training, reduced output and frustration among the people it is trying to develop.
Internal progression can also move a vacancy elsewhere. Promoting an experienced operative into a supervisory position may be the right decision, but their previous work still needs to be completed. The financial comparison should therefore include any resulting recruitment, redistribution of duties or additional training. Filling one gap internally does not always remove the need to hire.
What hiring really costs
Recruitment costs extend beyond finding a suitable candidate. Employers commit time to defining the role, reviewing applications, interviewing, assessing practical skills and checking relevant experience. Depending on the recruitment approach, there may also be advertising costs or agency fees.
Once someone joins, there are induction requirements, equipment costs and time spent introducing them to company systems and working practices. Even an experienced recruit needs to understand the organisation’s expectations, customers, processes and reporting arrangements. Technical competence can shorten the journey to effective performance, but it does not eliminate onboarding.
For international recruitment, the assessment should also include the relevant immigration processes, relocation arrangements and settlement support. These requirements vary by role and destination, so employers need a realistic plan based on the particular appointment. A clear understanding of the process helps the business compare options properly and prepare for the employee’s arrival.
The largest cost, however, may arise before anyone starts. A vacant role can leave equipment underused, increase overtime or force a business to turn work away. Those effects are easy to overlook because they do not appear on a recruitment invoice. Nevertheless, they belong in the commercial assessment of how and when to fill the position.
When hiring is the more cost-effective choice
Hiring becomes more compelling when the business needs expertise that cannot reasonably be developed internally within the available timeframe. A new contract may require experienced welders, a production facility may need specialist maintenance knowledge or a workshop may need additional qualified technicians to meet demand.
In these circumstances, choosing training solely because its initial cost is lower can be misleading. If the required capability takes too long to develop, the business may lose more through delayed output than it saves on recruitment. That does not mean hiring is always faster: candidate availability, notice periods and any relocation requirements must also be considered.
Recruitment can bring a further benefit through experience gained in other working environments. A new employee may introduce a more effective approach to fault finding, production planning or quality control. These improvements should not be assumed when calculating the business case, but relevant external experience can add value beyond filling an immediate vacancy.
Hiring is also necessary where growth requires additional capacity. A logistics business expanding its operations may need more drivers even if its existing team is highly capable. A manufacturer increasing output may need additional operators alongside better processes. Training can improve how effectively people work, but there are practical limits to how much extra demand the same workforce can absorb.
Comparing the costs fairly
A useful comparison starts with the same operational outcome and the same assessment period. For example, the business might need a particular machine running reliably across specified hours within three months. Both the training option and the hiring option should be assessed against that requirement.
For upskilling, the calculation should include training fees, employee learning time, supervision, cover and any pay adjustment associated with greater responsibility. For hiring, it should include recruitment, onboarding, employment costs and the period before the new employee reaches the required level of performance. Both options should account for the consequences of delays.
Care is needed to avoid double counting. If an employee’s normal salary is already included in the business’s payroll forecast, training time should not automatically be treated as an additional cash expense on top of that salary. The business should distinguish between money it will actually spend and the value of productive time it will lose. Both matter, but they describe different effects.
Lost revenue also needs careful treatment. Turning away work worth €20,000 does not necessarily mean losing €20,000 in profit, because completing that work would involve costs. Using the contribution the work would have generated after its associated variable costs gives a more useful basis for comparison.
A simple illustrative example shows why this matters. Suppose an internal development route costs €8,000 in training, cover and supervision, while recruiting an experienced person carries €14,000 in recruitment and onboarding costs. Upskilling appears €6,000 cheaper. However, if recruitment delivers the same required capacity eight weeks earlier, and that timing preserves €1,000 of contribution each week, its advantage could outweigh the initial difference. These are hypothetical figures, with other employment and backfill costs assumed equal, but the principle is useful: the timing of the return matters as much as the initial price.
Why a combined approach often makes sense
For many employers, the most practical answer is to recruit for immediate gaps while developing the workforce for future requirements. Bringing in an experienced specialist can provide capability the business currently lacks, while a structured training programme helps existing employees build related skills over time.
A manufacturing business might recruit a specialist maintenance engineer while developing its technicians’ fault-finding abilities. An automotive employer could hire additional experienced mechanics to manage current demand while supporting existing employees through further technical training. The recruitment creates capacity, while development strengthens the team’s longer-term capability.
Knowledge transfer needs deliberate planning. A recruit should not be expected to meet a full operational workload while informally training several colleagues without time or support. If mentoring is part of the role, employers should make that expectation clear and provide an appropriate structure. Otherwise, a promising idea can become another source of pressure.
International recruitment can form part of this approach where suitable candidates are difficult to secure through the employer’s existing recruitment channels. Its value lies in widening access to relevant skills and experience. Employers should assess it through the same full-cost framework as other options, including fair employment terms, preparation, onboarding and support for successful integration.
Making the decision work over time
Whichever route a business chooses, it should define what success looks like before committing expenditure. For a training programme, that might mean an employee completing a task independently to an agreed standard. For recruitment, it might mean restoring production capacity, reducing a backlog or enabling the business to fulfil additional orders.
Reviewing those outcomes helps employers make better decisions next time. Course completion rates and the number of vacancies filled provide useful information, but they do not show the whole return. Measures such as time to competence, quality, overtime, output and employee retention give a clearer picture of whether the investment has addressed the original problem.
Upskilling is often cost-effective when the business has suitable employees, a realistic development pathway and enough time to build the required capability. Hiring can offer stronger value when specialist expertise or additional capacity is needed within a timeframe internal development cannot meet. The right decision follows from the operational requirement and the full cost of delivering it.
