The apprenticeship gap
The UK engineering sector is entering one of its most acute workforce shortages in decades, with new data revealing a widening disconnect between labour market demand and the country’s apprenticeship pipeline
According to DART Tool Group’s Apprenticeship Gap Report, engineering now faces the most severe deficit of all technical trades analysed, with 145 job openings for every one completed apprenticeship – equivalent to more than 46,000 unfilled engineering positions.
For a sector responsible for national infrastructure, manufacturing productivity, energy security and industrial innovation, the risk is structural, not cyclical. Employers are encountering escalating recruitment delays, rising project backlogs and an increasingly ageing workforce. This analysis examines the engineering skills deficit through a technical and workforce-planning lens, drawing out implications for engineering managers, project leaders and industry strategists.
A DATA-DRIVEN VIEW
Across all six trades analysed – engineering, construction, electrical, plumbing, manufacturing and building services – the study found only 809 apprenticeship openings available to fill over 86,000 job vacancies nationwide. This translates into a sector-wide ratio of 106 vacancies per apprenticeship, but engineering sits significantly above that average.
Engineering maintenance is the most heavily constrained discipline, with nearly 550 vacancies for every newly qualified apprentice. Completion rates of just 34% compound the issue. Mechanical engineering follows closely at 488:1, with apprenticeship starts falling by 52.6% year-on-year and down 18.2% since 2021/22 – a worrying decline at a time when mechanical skills underpin major sectors such as manufacturing automation, aerospace, renewables and transport.
General engineering roles saw the sharpest decline in new starters: 83% drop year-on-year, 97% drop since 2021/22.
LOW COMPLETION RATES
Engineering apprenticeships have seen a sustained fall in completion outcomes:
- 45% in 2024/25
- 50% in 2023/24
- 42% in 2022/23
- 33% in 2021/22
While the long-term trend is improving compared to 2021/22, the recent drop from 50% to 45% is a reversal at precisely the wrong moment.
AN AGEING WORKFORCE
Around 20% of UK engineers are due to retire within five years, according to the report. Many who remain in the sector are transitioning into supervisory or managerial roles, reducing the pool of technically hands-on mentors. Apprentices entering the workforce encounter fewer experienced engineers available to provide the practical, nuanced guidance needed for equipment operation, fault diagnostics, system commissioning and site safety.
OUTDATED PERCEPTIONS
Despite the increasing sophistication of engineering – including digital twins, robotics integration and smart manufacturing – apprenticeships still suffer from outdated stereotypes. Many young people and parents remain unaware of the technical, well-paid and often future-facing nature of modern engineering roles.
TRAINING INFRASTRUCTURE MISALIGNMENT
The report highlights gaps in regional provision, limited on-site learning flexibility and an oversupply of learners in trades with limited local employment opportunities and vice versa. Engineering employers still report difficulty accessing aligned training, particularly in more specialised roles such as mechatronics, controls engineering and building services engineering.
STRATEGIC RECOMMENDATIONS
Ryan Paterson, managing director at DART Tool Group, emphasises that “with a stronger, more effective apprenticeship system and active encouragement and promotion of trade industry jobs, the risk of a widening skills gap can be reduced.”
Engineering employers can help shape curricula, modernise workshop equipment and ensure trainers remain up to date with evolving industrial technologies. Direct collaboration also increases visibility of apprenticeship pathways. Many small and medium-sized engineering firms struggle to release staff for extended off-site blocks of training. Hybrid models that combine digital learning, modular assessments and integrated job-site experience would enable more apprentices to complete programmes.
Data shows that engineering apprentices often leave programmes due to workload conflicts, lack of progression clarity or insufficient technical mentorship. Structured mentoring models, early-career skills bootcamps and access to high-quality tools and equipment can materially influence completion outcomes.
Paterson notes, “professional-grade site tools enable apprentices to complete their programmes, master technical skills, and build a stronger and more confident workforce without delaying projects further.”
ADDRESSING THE CHALLENGE
The Apprenticeship Gap Report provides a detailed analytical snapshot of a talent pipeline under significant strain. With tens of thousands of engineering roles unfilled, retiring experts leaving technical gaps, and completion rates falling, the sector faces a multifaceted challenge. But the report also points toward solutions: smarter workforce planning, deeper industry–education collaboration, and investment in the tools, technologies and training methodologies that support successful apprenticeship outcomes.
