About us

Every refrigerated truck and trailer moving goods across the country has relied on diesel for decades. It's polluting, expensive, and the technology hasn't changed. Two companies have dominated the market, selling the same legacy technology with minor updates.

Sunswap makes the electric refrigeration that's replacing it - zero emissions, lower operating costs, built from the ground up for how fleets actually operate. We've gone from founding to manufacturing at scale globally in just six years. We built our own production facility in Surrey. We are trusted by major brands like Tesco, Ocado, Birds Eye, and Happy Eggs every single day. With units operating across the UK, France, Netherlands, Belgium, Chile, and Australia.

We've been named Sunday Times Best Place to Work 2024 and 2025. We've won awards for innovation, technology, and marketing excellence. We've secured backing from BGF, Barclays, and Clean Growth Fund. We've got the customers, the traction, and the momentum.

Now we're taking this British-engineered product global. Scaling manufacturing. Opening new markets. Building the team that will make legacy polluting technology obsolete across the world.

If you want to be part of a company that's setting new standards for the industry and scaling internationally, this is it.
