A strategic clean-tech investment company shaping the future of water, energy and sustainable technologies.
ABOUT
Who We Are
Sustec is a UK-based investment and innovation platform focused on sustainability, efficiency and clean technology.
Founded by experienced industry operators, Sustec provides strategic direction, operational depth and long-term vision to a rapidly changing sector.
We partner with organisations that are advancing the way buildings, water and energy systems perform — companies with strong leadership, specialist capability and the desire to scale.
Our Purpose
To accelerate the adoption of sustainable technologies by investing in businesses that deliver measurable improvements in resource efficiency, environmental performance and operational excellence.
We support organisations that are ready for their next phase of growth and want to be part of a connected, future-focused group.
VISION
A Future of Intelligent Resources
We believe the world’s most valuable resources — water and energy — must be managed intelligently, sustainably and without compromise.
The technologies exist.
The expertise exists.
What’s needed now is a unifying platform capable of bringing the best together. Sustec exists to build that platform.
Where We Are Going
Our vision is to develop a high-performing portfolio of companies operating across:
Building Performance Systems
Water Efficiency & Smart Management
Data-Driven Optimisation
Clean Energy & Renewables
We see a future where:
- Waste is engineered out of buildings
- Water behaves like the renewable it should be
- Renewable technologies are seamlessly integrated
- Data informs real-time action
- Efficiency becomes the default, not the exception
This is the transformation Sustec is designed to deliver.
THE MISSION
To elevate the performance of essential resources through intelligent investment, strategic alignment and a commitment to long-term impact.
We don’t follow the transition to sustainable technologies. We help shape it.
