ABOUT TEG UK

Established experience. Evolving capability.

TEG UK has spent more than a decade working with leaders, teams and behaviour inside complex organisations.

Our roots go back further. Twenty years spent building and running businesses shaped our understanding of leadership, people and performance. That experience was followed by more than ten years working inside complex organisations, including nuclear, defence and engineering, where communication, decision making, challenge and accountability have real operational consequences.

Behaviour has always been central to that work. What has evolved is our ability to see it.

Technology now allows us to capture behavioural evidence as work happens, identify patterns across teams and organisations, and measure whether change is taking place.

That has taken TEG beyond traditional learning and development.

Today, we combine experienced human judgement, behavioural intelligence, technology and development to help organisations understand what is influencing performance, decide where to act and measure what changes as a result.

It creates one connected approach:

Understand and act → Diagnose and measure → Develop and embed

We work primarily across nuclear, defence and complex engineering, supporting organisations where better leadership, stronger teams and clearer decisions can make a measurable difference to performance.

We haven’t moved away from learning and development. We’ve built a way to understand where development is needed, target it more effectively and see whether it worked.

Our system:

TEGacademy

Develop and embed

TEGacademy turns insight into development. Through practical programmes, workshops and simulations built around real operational challenges, leaders and teams develop and practise the behaviours needed to make change part of everyday working.

I started TEG because I kept seeing the same problem. Organisations were putting their people through training programmes, good ones, expensive ones and six months later, nothing had really changed.

Teams were back to the same friction. Leaders were back to the same habits and nobody could quite explain why.

I’ve spent more than 20 years working in some of the most demanding environments the UK has to offer. Nuclear sites, defence programmes, major infrastructure projects. Environments where the gap between what leaders say and what they do isn’t just a performance issue, it’s a safety issue, a culture issue and sometimes a survival issue.

What I saw, again and again, was that behaviour only changes when three things are true:

• people know what good looks like,
• they practise it in conditions that feel real,
• someone is paying attention to what’s actually happening day-to-day.

Not in a survey six months later. That conviction is what built TEG UK.

1. TEGalign, the advisory work sets the standard.
2. TEGinsight makes it visible.
3. TEGacademy makes it practical. 

The loop closes and organisations stop guessing whether change is happening.

We’re the organisation that stays, does the work and shows you the evidence. If that’s what you’re looking for, we should talk.

Our mission:

TEG UK exists to help complex organisations improve performance by understanding and developing the behaviours behind it.

We work across nuclear, defence, engineering and other high-consequence environments where leadership, communication, decision making and accountability affect what happens every day.

Our approach combines experienced human judgement, behavioural evidence, technology and development. We help organisations understand what is happening, identify where change can make a difference, develop the people involved and measure what happens next.

More than ten years of working with behaviour has taught us something important. The better you can see what is happening, the better you can decide what to do about it.
