Company Mission
Nusku is leading the energy transition with a revolutionary new heating system that enables a seamless shift away from gas boilers to a more affordable and greener solution. Our mission is not only to reduce the carbon emissions from the UK’s 29 million homes, which currently account for 20% of the UK’s CO2 footprint, but also to reshape how people think about home heating.
