EDF Energy: Building a Coaching Culture in Safety-Critical Environments

About EDF Energy

EDF Energy operates nuclear generation facilities across the UK—some of the nation's most critical infrastructure. As one of the UK's largest energy companies, EDF manages nuclear sites where every decision, process, and conversation has consequences. The stakes are high: safety, regulatory compliance, operational reliability, and the expertise of thousands of people all converge in environments where precision is not negotiable.

The Challenge: From Command-and-Control to Coaching Culture

Safety-critical industries like nuclear generation have traditionally relied on hierarchical, command-and-control management models. Someone at the top makes decisions; others execute them. This approach has delivered decades of safe operations—and for good reason. In environments where a single error can have serious consequences, clear direction and accountability matter.

But EDF recognised something that leading organisations in regulated sectors are increasingly discovering: command-and-control leadership and coaching culture are not opposites. They can coexist and strengthen each other.

The challenge was threefold:

• How to develop decision-making capability at all levels without compromising safety standards
• How to shift from passive compliance to active ownership—where people don't just follow instructions but think critically about their work
• How to build capability at scale across a complex, multi-site organisation

That's where the Coaching Professional Level 5 apprenticeship came in. But this wasn't a standard training rollout. EDF's commitment required on-site delivery at their nuclear facilities—which meant navigating nuclear security protocols, site protocols, and the unique demands of a safety-critical environment. TESS Group's team, including Lisa O'Reilly and Rod Doyle, visited the nuclear facility directly to understand the operational context, meet the cohorts, and design a programme that would work within EDF's culture.

Why an Apprenticeship, Not a Training Course?

EDF Energy had already recognised that one-day workshops or short training courses don't create lasting culture change. A coaching culture requires sustained practice, reflection, and integration into daily work.

The apprenticeship model solved this because:

For EDF, this meant that learners weren't getting generic coaching theory. They were developing coaching capability in the specific context of nuclear generation—understanding safety culture, regulatory environment, high-stakes decision-making, and how coaching actually works in their world.

The Programme: Coaching Professional Level 5 + Senior People Professional

EDF Energy delivered two complementary programmes:

Coaching Professional Level 5

The foundation programme focused on developing core coaching skills. Apprentices worked on:

• Mastery of coaching models (GROW, OSKAR, and solution-focused approaches)
• Active listening and powerful questioning techniques
• Handling difficult conversations with confidence
• Understanding when to coach and when to direct—crucial in safety-critical contexts
• Supervised practice with real-world coaching conversations from their roles

Senior People Professional

Complementing the coaching apprenticeship, EDF also developed people leaders through the Senior People Professional pathway, ensuring that coaching skills were integrated with broader HR and people leadership capability.

What Makes This Delivery Different

On-site nuclear facility delivery. TESS Group's willingness to visit the nuclear site, understand the security and operational constraints, and co-design a programme that respected EDF's culture was not standard. Many training providers deliver off-site; EDF's learners received their monthly workshops on-site, reinforcing that coaching was integral to how EDF worked, not something separate to go on a course for.

Multiple cohorts, sustained delivery. What began as an initial cohort in mid-2025 expanded quickly. An October cohort followed, with discussions of a December cohort. This isn't a one-off pilot. It's an ongoing commitment to scaling coaching capability across the organisation.

Expert skills coaching. Elaine Denney and Jamie provided 1:1 coaching support to apprentices. This wasn't generic oversight—it was experienced coaches helping learners navigate the complexities of real coaching conversations in their roles.

Focus on learner outcomes, not just compliance. TESS Group's commitment to quality showed in the results: learners achieved distinctions through rigorous assessment and demonstrated mastery of both theoretical frameworks and practical application.

What Results Look Like in a Safety-Critical Environment

Building a coaching culture in nuclear generation doesn't soften rigour—it sharpens it. In a mature coaching culture at EDF, you see:

• Team leads coaching people through challenging safety incidents, drawing out learning and building independent decision-making capability
• Operations managers asking powerful questions that help teams identify root causes instead of just escalating problems
• Peers coaching each other on complex decisions in high-pressure situations—faster, better decision-making across the organisation
• Continuous development conversations that sit alongside formal reviews—building engagement and ownership
• A culture where people want to stay and develop, not just comply with rules

This is what transforms safety-critical organisations: not looser control, but more intelligent, distributed capability.

The Path Forward

EDF's partnership with TESS Group is already growing. Multiple cohorts have been delivered, with demand continuing. What started as a response to a single opportunity has become a strategic capability initiative.

For organisations thinking about building coaching culture in regulated, safety-critical environments, EDF Energy's approach shows what's possible: rigour and empowerment aren't mutually exclusive. In fact, they strengthen each other.
