The Kensa Group is pleased to announce the appointment of Tamsin Lishman as their new Chief Executive Officer as of the 1st October 2023, and the planned departure of Dr Matthew Trewhella, current CEO of the UKs leading provider of ground source heat pump-based solutions.

Tamsin’s appointment as CEO designate has been confirmed by The Kensa Group Chairman, Lord Taylor, following a rigorous selection process. Tamsin will take her place formally as CEO on the 1st October 2023, with a transition period from the 1st September.

Dr Matthew Trewhella will remain as CEO in the meantime, continuing to focus on delivering the Kensa vision and strategy for energy security and affordability through the mass decarbonisation of heating and cooling with networked heat pumps. He will work closely with Tamsin to ensure a comprehensive handover and a smooth transition. As of Tamsin’s formal take over as CEO, Matt will take up the position of Director of Strategic Business Development prior to his planned departure from the business on the 12th April 2024.

Tamsin is a visionary leader with an excellent track record of building high performing businesses. An Oxford graduate of Engineering Science and Fellow of the Energy Institute, Tamsin will join from her role as Chief Revenue Officer at ENERGYNEST. In this role, Tamsin has developed customer offers to provide green, reliable and affordable industrial heat, specialising in thermal energy storage and power to heat solutions across the UK and EU. Prior to joining ENERGYNEST, Tamsin held senior positions at Northumbrian Water Group, Centrica, and BP.

Tamsin Lishman, CEO designate, says:

I am delighted to be joining Kensa and to be part of a strong, successful and purpose led team. The mass deployment of Kensa’s networked ground source heat pump solutions is the 21st century alternative to gas, enabling the transition from fossil fuels and supporting energy security. Kensa’s offer of affordable, decarbonised heat and cooling to keep our homes and buildings comfortable is an essential part of the energy transition and I’m excited about leading the company in the next stage of growth.

Dr Matt Trewhella, who has been with the Kensa Group since 2013, has today (13th July 2023) announced he will be stepping down from the position of Chief Executive Officer, with a phased transition to the incoming CEO, Tamsin Lishman.

The decision comes after Matt’s considerable years of dedicated service and tremendous contributions to the organisation’s and ground source heat pump technology’s growth and impact, recently affirmed by a £70m investment into the Kensa Group by Octopus Energy and Legal & General Capital.

The Kensa Group consists of three UK-based heat pump specialist businesses: heat pump manufacturer, Kensa Heat Pumps; delivery partner, Kensa Contracting; and networked heat pump asset finance provider, Kensa Utilities.
Through Matt’s tenure, the technology and The Kensa Group have gone from niche to mainstream, with the realisation of networked ground source heat pumps and shared ground arrays becoming a credible alternative to the UK’s sustainable and affordable transition away from gas.

Dr Matthew Trewhella CEO of the Kensa Group comments:

Ground source heating has so much potential and it has been an incredible 10 years at Kensa. We are now completing projects at a scale and with such positive results that the technology is ready for mass deployment at the speed we need. On a personal level, it has been an honour and a privilege to work alongside an incredible group of capable and committed colleagues who have had the vision to join us on our exciting journey. I am taking a long-planned career break and will be avidly following Kensa’s progression over the next few years.

Lord Taylor, Chairman of the Kensa Group, says:

I am delighted to welcome Tamsin to Kensa. Already Kensa has achieved market leading amounts of decarbonisation as the UK’s largest installer of ground source heat pumps, and also made a massive difference to the alleviation of fuel poverty in thousands of homes. Tamsin as our next CEO will lead a fantastic team in ramping up our transformation of UK heating and cooling. I look forward to her leadership and contribution through this next exciting phase of our development which will bring the benefits of what we do to tens of thousands more homes across the country.
