I had the pleasure of working very closely with Tristan on the MHHS programme which saw the biggest mandated change in the energy sector since privatisation. Clear and robust product prioritisation, collaboration, product led workshops with customers to help shape their MHHS qualification and most importantly, team work were the outcomes. We hit every deadline we needed to across multiple clients which on a change of this scale should say everything you need to know about why it is a pleasure and a privilege to work with Tristan.
During very complicated deliveries Tristan is not shy to lead from the front and get involved with his teams in the tough moments. The biggest compliment I can give Tristan is the team he built at scale — his product teams, owners and managers are some of the best I have ever worked with. Any organization would be lucky to have Tristan.
I have had the privilege of working under Tristan's leadership for the majority of my professional career, and I can confidently say he is one of the most impactful leaders I have seen. He consistently pushes his teams to perform at their best, setting high standards while ensuring there is clarity around expectations, priorities, and outcomes.
Tristan's leadership style is honest, direct, and transparent. You always know where you stand, what success looks like, and where improvements are needed. He creates an environment where people feel trusted, encouraging thoughtful experimentation, independent decision making, and ownership. His ability to combine strategic vision with execution sets him apart.
I have had the pleasure of working with Tristan across several high-profile programmes, including the Market-Wide Half-Hourly Settlement initiative and multiple DCC adapter onboarding projects. He is a highly engaged, hands-on Head of Product who combines strategic thinking with strong operational delivery.
Tristan's breadth of knowledge across the energy industry is exceptional. His expertise — paired with his ability to simplify challenges and drive clarity — makes him an invaluable partner on complex programmes. His leadership style fosters collaboration, accountability, and momentum. Tristan would be a key asset to any organisation, and I would highly recommend him for any senior product or strategic leadership role.
I had the pleasure of working with Tristan in his role as Head of Product for Market Connectivity, where his energy and clarity of vision made a real difference to how our team operated.
He set clear goals and a strong strategic product direction, ensuring everyone understands not just what we were doing but why we were doing it. What really sets him apart is his ability to rally people around a common cause and motivate the team to deliver. I would highly recommend Tristan to any organisation looking for a product leader who combines strategic thinking, structure, and the ability to bring people with him.
I've had the pleasure of working with Tristan whilst delivering programme level change at ENSEK. Tristan showcased clear product vision, turning complexity into clear, measurable outcomes for our colleagues and clients. His customer-centric approach, technical knowledge and leadership have consistently driven strong results. Most importantly, Tristan mentors and inspires people around him, fostering a culture of accountability and continuous learning. I'd happily work with him again.
I worked closely with Tristan on and off over the years at ENSEK. He brought a high level of passion and determination to each project, leading by example and even stepping in several times to assist Engineering Management during periods of turmoil while still working as HoP. He is very results driven and says what needs to be said.
His outspoken support enabled us to keep delivering on MHHS during a very high-pressure period and gave me the space to create our monitoring and observability suite. I am really sad to see Tristan go and I hope our paths cross again!
Working with and getting to know Tris at ENSEK was a highlight — he's fiercely confident, deeply knowledgeable, and genuinely personable. He tackles tough challenges head-on, backs his ideas with real expertise, and makes collaboration feel easy and effective.
I've worked with Tristan since his start at Ecotricity and in a short time he's made a big impact on the business. Tristan was brought in to fill the Smart Capability Manager role but his influence is already pushing out significant change in our project management, strategy and technology areas — through his experience and competence, things are done right first time.
Tristan has very quickly gained the confidence of Executives as well as the wider Operations and Metering teams. I would strongly recommend Tristan for any role within Smart Metering, as well as Project Management across any industry.
I have had the pleasure of working with Tristan the past few years and can honestly say that his drive for excellence, and passion for his work has had incredibly positive effects in my team. Implementing new processes as well as leading teams both as a Lead QA professional as well as a PM, Tristan is not afraid to get stuck in and really engage with the team helping in multiple capacities. I look forward to working on future projects together.
Tristan is a highly motivated individual who successfully manages his colleagues and subordinates who have a multitude of personalities and skillsets. His passionate, confident attitude serves to motivate other project staff. Tristan naturally falls into a leadership role with a strong ability to identify each team member's capabilities and bring out the best in each one throughout the course of the entire project.
During the management of the most recent project, Tristan demonstrated an ability to effectively identify project priorities and pinpoint which methodologies were relevant. He focused on the stated objectives and created accurate estimates for each piece of work — giving the project a clear direction with minimised risk.
Tristan was a pleasure to work with at Gilmond, full of energy and new ideas. Direction was always clear and concise, with resolutions to issues affecting the efficient implementation of a project swiftly and effectively implemented.
