If you don’t have one, consider asking your supplier to provide you with one.
Install a smart thermostat
Heating your home drains electricity so instead of leaving it on all day, you can use a smart thermostat to control your settings from your phone.
This will also allow you to monitor your household’s patterns so you can make adjustments.
For example, your heating could be coming on at 1pm when no one is home until 3pm.
