Who we are

Sunswap is a UK clean-tech startup on a mission to decarbonise the cold chain. Our award-winning electric, battery and solar-powered transportation fridge, Sunswap Endurance, is purpose-built to match or exceed diesel.

Our goal is to help logistics firms and food retailers eliminate direct emissions, cut costs, and make sustainable zero-carbon supply chains possible. With each diesel unit we replace, we enable cleaner air and a healthier planet.

Introducing Endurance

We’ve combined outstanding performance, efficiency and reliability with zero emission to create the ultimate transport refrigeration solution. This is an electric transport refrigeration unit you can rely on to deliver.

“After a trial run with a unit earlier this year, we’re pleased to announce that Sunswap trailers will become a permanent part of our cold chain operation in the UK. As the only zero-emission cooling trailer on the market, Sunswap provides a huge opportunity for us to reduce the carbon footprint of our cold chain operation and strengthen our offering to customers. With positive results from the trial, we are now set to place an order for multiple units, which should enter our service within the next year.”

Matt O’Dell – Managing Director UK


“Due to the high utilisation and efficiency of our temperature-controlled fleet, I was initially sceptical that any battery-powered refrigeration unit would be able to meet the high demands we put on our equipment. I and the team at Freshlinc were pleasantly surprised with the performance of the Sunswap system and how it handled the requirements that come with delivering fresh produce. As well as the rich level of data provided throughout the trial. We’re huge advocates of any innovation that can support our industry. I’m pleased to see Sunswap have created true competition for diesel fridges.”

Lee Juniper, CEO


“Our partnership with Sunswap allows us to offer our customers another sustainable solution for their refrigerated trailer fleet management needs. We are excited to be at the forefront of the industry in implementing green technology to reduce our carbon footprint.”

‘MMID trialled the zero-emission Sunswap Endurance in our fleet earlier this year to align with our Net Zero ambitions. We were impressed with the performance of the system and its ability to run for the entirety of the trial on free clean energy generated by the solar panels’

Samworth Brothers

“A key component of Samworth Brother’s vision to be a long-term force for good is our Net Zero target. This year we’ve been trialling a range of EVs as we look to cut our fleet’s reliance on diesel. Including the fully electric Sunswap Endurance. We were very pleased with how the unit seamlessly slotted into our operations and thwarted any of our attempts to “break it” during the trial. Completing all our delivery cycles with no downtime for charging, running entirely on solar energy generated by the panels on the roof.”

We were hugely impressed by the potential of Sunswap’s technology during September’s trial. We’re excited to work closely with Sunswap to help advance transport refrigeration in a more sustainable direction that meets our customers’ growing demand for zero-emissions deliveries, vastly reducing our reliance on fossil fuels and shrinking our carbon footprint. This bold transition is possible because we know Sunswap can deliver the sustainable technology needed to drive our industry forward.
