Bristol Energy has become the first energy supplier in the UK to trial selling ‘heat as a service’, offering households the chance to buy a tailored ‘Heat Plan’.

The government-backed trial is being run by Energy Systems Catapult. Heat Plans provide consumers with room-by-room, hour-by-hour control over their heating. Using data collected via a smart heating control system, the energy provider can calculate a fixed monthly cost that is bespoke to the triallist’s home and lifestyle and does not fluctuate with the weather.
