UK households used 15% more heating in March 2020 than the corresponding month last year, tado research found.
More homes were occupied in the day due to the coronavirus lockdown, while an average outdoor temperature of 1°C also had an impact.
An average UK annual dual fuel heating bill comes in at approximately £1,200, with heating and hot water accounting for around three quarters of an average energy bill.
Turning down the thermostat by 1°C saves around £80 a year on the average household energy bill.
However using a smart thermostat to control the heating and hot water can also make significant reductions.
Christian Deilmann, co-founder and chief product officer of tado, said: “Many people end up heating the whole home when in fact only some rooms are occupied where heat is needed.
“Smart radiator thermostats provide intelligent control and heating schedules for individual rooms which can save a lot of energy from being wasted.”
