About Insite Energy - Your heat network partner

Our journey

Built to support you, not just your network

We started back in 2009 to give housing providers and property managers a real choice in metering & billing solutions. At the time, the market lacked flexibility and wasn’t built with operators in mind. So, we built something better.

Since then, we’ve grown into a full-service partner for heat networks across the UK. Supporting it all, our dream to empower communities for a greener future by providing innovative, sustainable heat network solutions while fostering trust through exceptional service.

Everything we do, from launching new services to refining old ones, is designed to make your job easier and your networks better.

Metering & billing - Greenside Views

The savings are genuinely impressive. There is no trade off with taking the more affordable option as one might normally expect. Not having to fit hard-wired in-home displays is a huge advantage and we’re getting a great level of energy data.
