Growing skills,
growing business

Trainer Martin Heib guides installers through a hands-on workshop. In two to four hours, participants translate theoretical planning into practical competence with Hager’s product portfolio.

Stronger installer businesses, fewer warranty claims, safer buildings: Hager’s training programmes generate returns that reach far beyond the classroom. A formal impact assessment is putting the numbers behind them.

In a training workshop at Blieskastel, a group of electricians is wiring a simulated meter panel to the latest regulatory standard. The room is focused and quiet, save for the snap of terminals and the occasional question to the trainer. By afternoon, these participants will leave with competences they did not have that morning. What happens next, out on real job sites across Europe, is where the value begins to compound.

Hager’s training ecosystem spans three centres in Germany alone, with 22 dedicated trainers, 300 webinars a year, and more than 40.000 digital learners. In 2025, the German programme trained and informed 84.081 participants. The scale is considerable. The question Hager wanted to answer was whether the returns were equally significant.

Quantifying the return

To find out, Hager is conducting a Social Return on Investment assessment across different phases. “Training is a strategic differentiator for Hager. By training first, we position ourselves ahead of our competitors,” says Yves Peters, Director of Training. “But we wanted to go beyond intuition and put credible numbers behind what we observe every day.”

The early findings confirm what the training teams have long sensed on the ground. After completing modules in energy management, e-mobility, or connected-home technology, installers diversify their services and take on projects they previously had to decline. Case studies show average basket values¹ increasing by 22 to 40 percent. Corrective site visits drop by up to 50 percent², freeing capacity and reducing material waste. “When an installer completes our energy management or e-mobility training, they gain the ability to offer services they were previously unable to deliver. That translates directly into revenue growth,” explains Yves Peters.

Retention, trust, and reduced warranty exposure

The benefits flow back through the value chain with equal force. Professionals who are trained correctly install products correctly. That means fewer warranty claims, lower after-sales costs, and products that perform as designed over their full lifetime. For end users, the outcome is a safer, more reliable installation delivered by a qualified expert, and that experience builds lasting confidence in the brand behind it.

“Our training is fully integrated into our Customer Relationship Management (CRM) system. After every session we follow up with documentation, product guidance, and ongoing support. That continuous relationship keeps installers connected to Hager,” says Yves Peters. Those who complete the learning programme adopt digital tools such as Hager Ready and Hagercad, develop deep familiarity with the product ecosystem, and are more likely to specify Hager solutions in future projects. The retention effect is tangible and cumulative.

A wider outcome

Beyond business performance, the assessment captures societal benefits. Better-configured installations reduce energy consumption in buildings. Fewer rework visits mean fewer kilometres driven and lower CO₂ emissions. Improved regulatory compliance reduces the risk of electrical incidents. Each trained professional carries these benefits into dozens of projects annually.

“Every hour freed by better training becomes an hour reinvested in higher-value, lower-carbon work,” reflects Yves Peters.

Back in Blieskastel, the workshop is wrapping up. The meter panel passes inspection. The electricians pack their tools. Tomorrow, what they learned here will shape how a building performs for decades. The return on that investment reaches far beyond the training room.
