Who are we?

Sero was founded to make a connection between homes and energy, and to use technology to make both these easier and smarter together. We do this to save our customers money and to save them time, but we also do it to save our planet. To tackle the Climate Emergency, we provide clever energy services that automatically reduces the carbon footprint of the homes we run. To do this, we work with other home builders and landlords to help them understand what to do with their buildings to achieve this. We also try and lead by example, so through our sister company Sero Homes we build true zero carbon homes, set in ecologically vibrant spaces and places (there’s a and Biodiversity Crisis too!), so that our homes help to build a community. 


If you think we’re a match, please get in touch! We’d like a C.V., but send it with a covering note too please that tells us why you’d be our perfect fit for our team.

Your note can be a letter, email, video snippet, go crazy, give us a little bit of your character..
