The Shoebox NX ground source heat pump from Kensa has won the International Technology Energy Award at this year’s Energy Institute’s International Energy Awards. The 2025 awards received over 140 entries from 29 countries.
According to a statement, the Shoebox NX, designed and manufactured in the UK, enables large-scale adoption of renewable heating through the networked heat pump model, providing thousands of homes with efficient, low-carbon heating in one go. The compact heat pump can also help solve energy efficiency challenges, it noted, with the potential of lifting EPC ratings by up to two bands in low-scoring properties.
The statement added that thousands of homes, from new builds to century-old Edwardian social flats, are currently heated by Kensa’s original Shoebox heat pump.
In social housing, it said, networked heat pumps are helping providers decarbonise their stock, boost energy efficiencies and cut resident energy bills. The statement added that they’re also ensuring new build homes meet the upcoming Future Homes Standard, which will phase out installing gas boilers in new properties.
Tamsin Lishman, Kensa’s CEO, said: “It’s brilliant for the Shoebox NX heat pump to receive this prestigious Energy Institute award. The game-changing, compact heat pump has redefined what ground source heat pumps can deliver.
“When designing, our goal was to create a high-performance heat pump that delivers reliable, efficient heating for those who need it most. The Shoebox NX does exactly that – and more – and brings us closer to a future where every home has access to better, more efficient heating.
“The Shoebox NX is a superb example of British innovation, engineering and manufacturing, and tackles one of the biggest challenges in the transition to net zero—decarbonising heat at scale. From social housing flats to listed buildings and new build homes, the Shoebox NX is destined to become a cornerstone of the UK’s heating future.”
