I have a 1 bedroom flat built in 80s but retrofitted with electric heating that are of modern design set to 22c all year. Did all the insulation etc and my monthly bill is £30 and in credit by 200 when summer rolls around. You do miss gas for cooking though and this flat previously had gas![]()
Electric is 3x the price of gas where I am, but having the ability to heat just the room you are in could half that additional cost.
