Installers Train Under Pressure

Training only matters when you don’t have it… and that moment usually shows up mid-install. Something doesn’t line up, the sequence feels off or the system doesn’t respond the way it should. 

From there, you start double-checking the autopilot – you reread a label, second-guess the order of steps, wonder if it’s to do with the product, the setup or something you missed. Meanwhile, the clock keeps running. The customer is nearby. The next job is already waiting.

Good training shows up before that point. It shortens the pause when something looks unfamiliar. It turns We’ll figure it out into Oh, we’ve seen this before. And when the job is done, it disappears again. No drama or certificates, just fewer problems carried into the next install.

Strip back our European Mechanical Installation Monitor Q4 2025, the message is clear. Across Europe, installers are juggling heating, hot water, heat pumps, ventilation, controls, sometimes electrics, sometimes solar. The work is broader, the systems more connected, and the margin for error far thinner. So training carries real consequences, and installers gravitate toward formats that reduce uncertainty fastest. And being surprisingly consistent about it.

The Job Dictates the Learning

Let’s start with the work itself. Across the surveyed markets (UK, Germany, France, Poland, Belgium and the Netherlands), core HVAC activities are stacked high and wide, with the usual workload: installation, maintenance, commissioning, troubleshooting. That’s where time goes, and that’s where mistakes cost money and reputation.

At a European level:

• heating installations are done by 82-98% of installers
• hot and cold water installations sit between 77-97%
• heat pump installations already involve 60% of UK installers, 71% in the Netherlands, and a massive 95% in Germany
• ventilation runs as high as 86% in Germany and 82% in the Netherlands

Meaning niche work has become mainstream. And here’s the part that matters for training: the more complex the system mix, the less room there is for guesswork. You can’t keep figuring it out on-site forever when commissioning, controls, refrigerants and regulations all collide. 

This explains why installers are picky about training formats. When the work is physical, sequential and without a doubt unforgiving, learning has to be grounded and has to map directly to what happens on site. If it doesn’t, it won’t survive contact with a full calendar.

Face-to-Face Still Carries Weight

Digital training, webinars, on-demand platforms, AI-powered learning… yes, and ho! Sounds great, but is actually a bit more complex. When installers were asked how they prefer to train going forward, online-only came dead last in almost every country.

• only 7-8% of installers prefer online-only training
• face-to-face training is the most preferred format overall
• a balanced mix of online and face-to-face is widely accepted as a practical compromise

And while this resistance seems anti-digital, it’s really more about effectiveness. Acceptance goes up across the board, even in the less-inclined markets, when online is combined with face-to-face.

In a room, with the system right in front of you, things get resolved fast. Someone asks the naive question before it turns into a costly mistake. Someone else flags what goes wrong in practice, but never shows up in manuals. You see how it’s supposed to look, sound and feel when it’s done right. One session like that saves hours later. France, Belgium and the Netherlands are especially clear on this. In those markets, online-only training is the least attractive option by a long way.

Poland is the exception, at 8% interest in online training, which likely reflects a tighter labor market rather than a preference for screens.

That lines up perfectly with how installers already work. They’re happy to check something quickly online. They’re not interested in being told that a screen replaces hands-on time with a system they’ll be responsible for later.

The Topic Decides the Format

Training preferences depend on risk-profiles. For the most important topics, face-to-face is an unsurprising favorite. These are high-stakes areas; get them wrong and the consequences domino straight into the site. Breaking things down, we’re talking about:

• • product installation (up to 63% in the UK)
  • troubleshooting (45-58% depending on country)

• maintenance

• commissioning

• technology-specific training (heat pumps, ventilation, controls)

Product training is different. Products change. Specs update. Sometimes you just need a clear walkthrough you can revisit or a quick glance at the update. That fits digital formats well, and it’s probably why – in the UK and Poland – online training is equally treated, or even preferred, when the topic is product-specific. 

So the argument structure is learn the theory online → handle the hardware in person → solve problems face-to-face.

Why Is Training Dropping?

Looking at the numbers, training participation has softened since 2023. But let’s add context to the situation.

In 2025:

• around 73-81% of installers across markets still attended at least one training
• France’s 56% show the largest decline in participation
• Belgium is the only market where participation held up better, hitting a steady 76%

This drop lines up with tighter order books, labor shortages and less time (… not less need!).

In fact, half of European installers say they’re more likely to buy from manufacturers who provide training. In Germany, Poland and Belgium the preference reaches 53%, while France is at a somewhat lower – but still meaningful –  32%. 

Labor Shortages Are Pushing Training

A quick snapshot of the continent leads us into a familiar chorus. 70% of Polish installers report labor shortages, we’re seeing 60% in the Netherlands and around 40-47% in Belgium, the UK and Germany. Looking ahead, roughly every second installer expects labor shortages to remain an issue for the next five years. 

So how do they plan to deal with it? Hire non-qualified staff and train them internally. So there’s even more weight on clear training structures, manufacturer-led education and practical, repeatable learning formats.

When experience is thin, training becomes the safety net.

Timing Matters Too

Another detail that often gets ignored is when training happens. The first half of the year is the preferred training window, spring to early summer works best and autumn is consistently the least attractive period. Why? Look at the workload. Installers aren’t refusing training. They’re just cautious about doing it at their busiest.

However, there’s also a sizable group in every country that reports no strong seasonal preference, which gives manufacturers flexibility if the content is worth their time.

The Bottom Line

Nothing in the EMIM Q4 2025 points to installers being disengaged from training. What it does show, however, is professionals operating under constraint.

That’s why face-to-face still anchors learning where mistakes are expensive. That’s why online works best as reinforcement, not replacement. And that’s why blended models win when they respect how jobs actually unfold, not how training calendars are planned.

Installers aren’t asking for more training. They’re asking for training that earns the hours it takes. Manufacturers and training providers who treat training as operational support (that’s practical, timed right and tied directly to real installs) stay relevant. Those who treat it as content delivery will keep wondering why attendance softens while complexity rises.
