My 3 bed terraced house is well insulated and is heated by 3 Creda TSR sensor plus storage heaters, 2 X 2.5kw and 1 X 3.4kw heaters. Our electricity bill for last winters heating and hot water was £336. Unlike gas heating, storage heaters need no servicing. I switch mine on in late October and off in March and don't have to touch them from year to year as the latest ones only charge when they need to. Plus you get heat from them 24/7 unlike gas heating. Look on the internet for prices of storage heaters. Hope this is of help to you.
