Nearly a quarter of data center workforce in UK, Ireland and Nordics to retire by 2036

Retirement rates by region

The survey highlights varying retirement rates across the three regions. In the UK, 18.74% of the data center workforce—equivalent to 4,455 roles—is expected to retire. Ireland faces a higher rate, with 24.43% of its workforce, or 813 roles, set to exit. The Nordic region anticipates the largest proportionate loss, with 28% of its workforce, or 974 roles, retiring within the next decade.

Overall, approximately 6,340 workers across the UK, Ireland, and Nordic countries are projected to retire between 2031 and 2036. The survey also found that 10% of businesses expect over 40% of their employees to retire, amplifying concerns about concentrated knowledge loss.

Industry response

Matt Salter, Global Head of Data Centres at Onnec, emphasized the need for proactive measures. According to TechRadar, the industry is increasingly considering structured apprenticeship programs and mentoring initiatives to bridge the gap. These efforts aim to transfer knowledge from retiring employees to new entrants while ensuring operational continuity.

However, the scale of the challenge suggests that traditional training methods may not be sufficient. The industry’s rapid expansion—driven by AI and cloud computing—adds urgency to the need for scalable solutions, such as digital training platforms or automation tools that can offset workforce shortages.

This retirement wave adds to existing pressures on the data center industry in Europe. A recent investigation by Lighthouse Reports found that most European data centers, including those in the Netherlands, are not disclosing their energy and water usage. This lack of transparency complicates efforts to align operations with sustainability goals and could exacerbate regulatory scrutiny.

Additionally, a study by Emergn revealed that nearly a quarter of UK senior leaders may be overstating their AI knowledge, highlighting a broader issue of skills gaps in the technology sector. The data center industry’s challenge is part of a larger trend: rapid technological change is outpacing workforce readiness, and industries must adapt or risk operational disruptions.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

The data center industry in the UK, Ireland, and Nordic countries is facing a looming crisis: a fifth of its workforce is set to retire within a decade, taking critical institutional knowledge with them. For founders and operators, this isn’t just a hiring challenge—it’s a signal to rethink how expertise is preserved and transferred.

Apprenticeships and mentoring are obvious tools, but the urgency suggests a need for structural changes. Will companies invest in immersive training programs, or will they turn to automation and AI to fill gaps? The latter could accelerate cost pressures, especially as-demand for AI infrastructure grows. Operators may also need to compete harder for talent, potentially driving up wages in an already competitive market.

For investors, this trend could reshape valuations. Companies with robust knowledge-transfer systems or innovative workforce solutions might gain an edge, while those slow to adapt could face operational risks. The retirement wave also underscores the need for long-term planning—something often overlooked in an industry focused on rapid scaling.

Key takeaways

• The retirement wave will disproportionately impact roles requiring specialized experience, such as operations and maintenance, where knowledge gaps are hardest to fill.
• Founders in the data center space may need to allocate resources to training and retention earlier than planned, potentially increasing near-term costs.
• This trend could create opportunities for startups offering workforce solutions, such as AI-driven training platforms or talent-matching services tailored to the sector.
• Investors should factor workforce stability into due diligence, as companies with aging teams may face higher operational risks.
