A smart energy platform for the age of the smart grid
PassivSystems have developed a range of home energy services which are changing the landscape of the energy industry. We are a pioneering company at the forefront of making energy use more efficient and more affordable for millions of households. Our motivation is to help consumers, asset owners and businesses get better value for money and to make a significant difference to global emissions
In 2010 we were the first company to launch a smart thermostat that allowed consumers to remotely control their heating. In 2015 we became the UK’s No 1 residential Solar PV asset management services business and in 2016 we launched the world’s first predictive load management service for optimising CHP equipment on residential district heating networks.
