Developing Positive Workplace Cultures for 25 Years
Established in 2001 by our CEO and HR’s Most Influential Thinker, David Liddle, The TCM Group has been working with our customers to develop people-centred management practices, empowering HR processes and transformational workplace cultures. These practices, processes and cultures have been designed to improve productivity, increase engagement, drive collaboration, enhance wellbeing and turbo-charge your organisation.

The TCM Ecosystem
Over 25 years at the cutting edge of culture, leadership and transformation.
What sets TCM apart is our unique insight into people, relationships, workplace cultures, HR systems, leadership practices and management behaviours. We have combined this expertise into a world-leading portfolio of culture change, HR consultancy, leadership development, investigations, mediation, coaching, and conflict resolution programmes and consultancy.
Great Cultures Starts with Great Conversations
Our accredited five-day National Certificate in Coaching Skills™ equips managers and leaders with the confidence, practical tools and evidence-based techniques to unlock potential, build trust and empower others to succeed. As the foundation of TCM’s innovative Integrated Coaching System™ (ICS), it creates a shared coaching language that develops confident leaders and embeds coaching into the everyday culture of your organisation.
As technology reshapes the workplace, our competitive advantage lies in developing people who can think, adapt and grow. Coaching is a strategic capability that helps organisations build the leadership, culture and resilience needed for long-term success.
We describe coaching as the gift that keeps on giving…

“Couldn’t fault the service provided by David and the team in helping us set up an internal resolution procedure and mediation team. We had fantastic feedback from all our colleagues who attended training with them.”
“TCM has supported us to deliver our policy to resolve issues and establish a culture of fairness, trust and mutual respect. It is no surprise that in a business which employs so many people, there will be disagreements from time to time. TCM has helped us to establish a modern system for resolving these disagreements quickly and professionally.”
“The mediation and resolution training that TCM delivered was first class – engaging, thought provoking and highly professional. David’s collaborative, future focused and solution focused approach to conflict resolution really resonated with me and my team and aligns neatly with our brand values and people strategy.”

Putting the Human Into HR
The traditional human resources (HR) function is evolving. The emergence of the People and Culture function presents enormous opportunities for HR to deliver fair, just, inclusive, sustainable and high performing systems, processes and cultures. TCM is working with an increasing number of HR teams to help them as they evolve into a people and culture function. From the development of a people and culture strategy to the design and deployment of modern employee handbooks, values and behavioural recruitment processes, and transformational performance management systems. If you want to put the human back into HR, we are here to help.
Evidence Based. Practically Delivered
The use of data and evidence to inform and evaluate organisational change programmes is central to their short- and long-term success. We build a business case for cultural transformation using normative, qualitative and quantitative approaches such as existing HR and management data, and the engagement of key stakeholders such as people and culture professionals, leaders, managers, employees and unions.
Award-Winning Training from The TCM Academy.
Through TCM Academy, we design and deliver a wide range of award-winning training courses and events on a virtual, face to face and blended basis. We deliver public courses (open access) and we tailor our programmes to be delivered inhouse – to cohorts from 6 to 600. Here are just a few of our upcoming courses and events.

A Consultancy You Can Trust!
In 2023, we won the prestigious Personnel Today HR Impact Award in partnership with Burberry. (Not satisfied with just one trophy, we won the same award again in 2024 with Next)
Working with the TCM Group, Burberry conducted an audit of its team climate, systems and policies, identifying a number of key areas for improvement: upskilling HR and leaders in conflict management; reviewing policies and steps to resolution; a need for a confidential whistleblowing helpline only used for the most serious issues; and alignment of investigations processes so they were globally consistent. Feedback suggests that colleagues now feel more empowered to speak up, and there has been an increase in issues being resolved without the need for recourse to a formal procedure.
The Day That People, Culture and Leadership Aligned
On the 3rd July 2025, The TCM Group’s CEO, David Liddle, was honoured to win two prestigious awards: HR’s Most Influential Thinker 2025 and Consultancy Awards’ Consultant of the Year 2025.
