The Intergenerational Advantage: Why Construction Firms Who Blend Ages Will Outperform Everyone Else

Across the UK, the construction workforce is ageing faster than it’s being replenished. There are 20% more workers aged 55+ than under 25. And it gets worse: 35% of the workforce is now over 50, and only 20% is under 30. 

Yes this presents an industry risk, but closer to home we see organisational risk.

Leaders worry about recruitment, apprenticeships, T levels, Skills Bootcamps all useful, but none of them address the real issue:

Experience is walking out of the door every single day, and new capability isn’t being integrated fast enough.

This is exactly what my conversation with Colin McEllin MCIOB of Clan Contracting highlighted. When a 21 year old commercial graduate joined Clan Contracting, Colin didn’t roll his eyes or think, “another kid who’s never been on a site.” He leaned into it and welcomes thoughts, ideas and advice from 'young Aaron'. Massive benefits for him, and Aaron, and the wider team. 

The construction sector is staring at a workforce cliff edge:

• 140,000+ vacancies lie unfilled. 

• By 2036, 750,000 skilled workers will retire, stripping the industry of vital capability. 

• The UK will need nearly 1 million additional construction workers by 2032. 

Yet recruitment alone isn’t enough. You cannot hire your way out of this crisis.

We must integrate generations on purpose, not by accident.

Younger talent offers:

• Modern thinking around sustainability and digital tooling

• Analytical approaches and better documentation habits

• A willingness to question processes that haven't been updated since the 90s

• A commercial lens shaped by newer training systems

In Colin’s words, their thinking “took him right back to when he was 21” eager, energetic, ideas driven.

You want that energy before they lose it.

Your experienced people have:

• 30+ years of instinct

• Pattern recognition that no textbook teaches

• Quiet influence that stabilises teams

• Technical fluency on heritage, concrete, structure, sequencing, conservation, problem solving

These people are your institutional memory. Once they go, they’re gone.

And currently, UK engineering employers admit they only retain knowledge effectively from 57% of retiring staff. 

That is a crisis hiding in plain sight.

1. Create deliberate two way mentoring (not hierarchical mentoring).

Younger staff teach digital skills, new processes, sustainability thinking. Older staff teach technical judgment, site sense, risk spotting. Both feel valued.

2. Give young people actual responsibility, not token tasks.

The CITB plans 40,000+ industry placements a year. It means nothing if leaders hide young people in the corner. 

Let them make decisions, with support.

3. Systemise knowledge transfer.

You cannot afford to rely on “ask Dave if you need help.” You need processes, templates, technical walkthroughs, shared documentation.

4. Remove the “that’s not how we do it here” reflex.

76% of construction workers say current training doesn’t adequately prepare people for the job. 

So your way probably isn’t the best way anymore.

Your Competitive Advantage Is Sitting Right Under Your Nose

When generations work in isolation, capability leaks.

When generations work together, capability compounds.

The firms who win over the next decade won’t be the ones who grab the talent, it will be the ones who blend talent.

I write about topics that my podcast guests bring to the podcast. They have years of experience with challenges and opportunities along the way, highs and lows and are in the thick of leading with purpose and passion, faults an'all. As a coach and trainer I work with leaders and their times to help them thrive, laugh, enjoy their work, be productive and to build teams of all ages.
