What we do

“We were looking for support from an organisation that could help us hone our proposition and offer market intelligence. We know the technical side inside out, but needed broader energy system expertise to understand the landscape in depth and direct our approach to market. Energy Systems Catapult ticked every box. The Innovator Support Platform has opened doors for us, giving us access to expertise and markets we couldn’t have accessed on our own.”

“As one of the only SME operators in the ZEHID consortiums, we’ve spent over three years learning what it actually takes to run electric HGVs in general haulage and pallet network operations. The tools and insights the Catapult are releasing translate that hard-won operational experience into something every fleet operator can act on, regardless of their size or resources. The transition to zero-emission freight can’t depend on every operator figuring it out alone and now, thanks to this work, they don’t have to.”

Chris Welch, Managing Director
Welch Group

"There are not many market companies who specialise in the sector. So getting this type of support would have been difficult and probably quite expensive. Also, the Consumer Insight Team have experience working with consumers through the Living Lab [providing access to] real energy data and real people, on actual real homes, which has a massive role to play in the quality of the output that they provide.”

“The Net Zero Living programme provided Heatio with invaluable real-world consumer insight at a pivotal stage in our development. Working with Energy Systems Catapult enabled us to validate our assumptions, understand how homeowners engage with retrofit decisions, and identify where the greatest barriers to adoption exist. The findings directly influenced our strategic direction, helping us evolve our platform and launch Heat Pump Ready, a solution that now supports installers and homeowners with data-driven retrofit recommendations. The project gave us the confidence and evidence needed to refine our product, strengthen our commercial proposition, and accelerate our route to market.”

“This collaboration has been instrumental in shaping our approach to commercialisation in the UK. Through ITES and our work with the Catapult, we’ve been able to validate our technology in real-world conditions and build confidence in scaling manufacturing locally. It’s played an important role in our decision to invest in UK-based production and job creation as we move towards deployment.”

Will Tope, CEO
LiNa Energy

“Collaborating with the Catapult not only provided us with actionable insights to improve our product, but also equipped us with credible, evidence-based research. This has been essential in building trust and opening doors with leading institutions and industry partners.”

“Participating in the Inclusive Smart Solutions (ISS) programme was a key part of our journey in creating a community-led retrofit feasibility service for blocks of flats – a typology that is massively underserved in retrofit planning and delivery. Having access to partners with service design and commercial forecasting expertise was particularly valuable, and has enabled us to develop a service that works for residents, landlords, and building managers and is viable in the marketplace. Building from these foundations, we’re now validating our service at scale, working with blocks of flats across London – totalling approximately 500 households.”

"The Living Lab is a fantastic resource for enabling network operators to see the real-world impacts of their innovation projects. The Catapult team and Living Lab participants are responsive and willing to try anything. The results are detailed and insightful; in a way that modelling on its own cannot provide."

Kevin Stewart, Future Networks Project Manager

“The Local Area Energy Planning work is powerful because it identifies not just the type of technologies which will be needed for this transition, but their scale, indicative locations and costs. We are now rolling LAEP out across the other nine authorities of Greater Manchester to inform future planning, developments and programmes.”

Mark Atherton, Director of Environment
Greater Manchester Combined Authority

"Water availability is an increasingly important factor as we transition to a Net Zero energy system. At National Grid Electricity Transmission, we recognise the need to consider the interdependencies between critical infrastructure sectors, including the impact of water constraints on the electricity transmission network. We are proud to have partnered with Energy Systems Catapult, who have provided valuable analysis to support a more informed approach to energy system planning."
