Myself,wife + 2 kids.
Electric is £60 pcm
Gas is £25 pcm
I admit that we hardly use gas at all.
We have 2 pc's,2 tv,s and a ps 3 almost permenately on.All washing is tumble dried and we use an electric heater instead of the central heating which is hardly used.
Electric is 8.67 pence per unit.
Gas... no idea.
