hi,, i dont think its you,, i currently have both gas and electric three teens,, have a timer for the heating,, for one hour in the morning,, and and back on in the evening for 3 hours,, same as you for washing and drying,, between both gas and electric i am currently using £45 per week,, i heat the water over night.. i switch it on at 1 am,, yes i get up to do this, and turn it off at 5 am. i cant afford, i have now turned of the heating, and told the kids to wear more clothes as its cold in the house, im disabled and cant afford the heating... i think having a pre paid meter you pay more for that option. i worked out that quarterly, im paying just under £600 sorry if that sounds depressing, but its too expensive
