A Net Zero future
starts at home.
What we do
Here at Sero we believe that a green, Net Zero Carbon home should be a possibility for everyone. We understand that the journey to Net Zero and a greener, more sustainable way of life looks different for everyone, but also believe that the move to decarbonise the way we live shouldn’t mean a compromise in comfort or cost.
We think outside the box
Combining industry leading construction and digital expertise to deliver ground-breaking living solutions. Our Passport provides property owners and developers with a clear set of steps to achieving a carbon zero portfolio of homes. Meanwhile our Comfort Service helps the families in those homes navigate their journey to a greener future.
We have created an invaluable tool to understand how your home, building project, or housing stock contributes to the UK’s climate challenges and our pathway provides you with solutions on how to tackle it, together.

Comfort is key at Sero
We are passionate about ensuring that the families living in homes with our forward-thinking technology understand that we are here for the long haul! Our comfort service, Sero Life, offers families a route to effortlessly achieve comfort at the lowest possible cost, carbon footprint and in the least amount of time, through intelligent home controls. We are here to help you save time, save money and save the planet.
Why we do what we do
Put simply – because we need to
Net Zero starts at home
40% of the UK’s carbon emissions come from households, how we build and live in our homes, makes up a big proportion of this. As a nation, we will not succeed in fighting the Climate Emergency if we don’t effectively eliminate carbon emissions from every one of our homes.
We do this for ours, for yours and for future generations. Sero is for our future.
Who we are
The journey to net zero is not a journey we can do alone. The people we surround ourselves with, from our team and our customers to our partners, all share a common goal of creating a better, brighter, greener future for how we live.
