Mine was £129 per month direct debit before I got moved from Avro to Octopus Energy with a £500 credit in hand. I've been monitoring the usage as my £500 credit was disappearing fast. We were going through approximately £180 a month.
We have an electric oven and four kids between 16 and 23 that were all eating at different times and using the oven several times a day. It really annoys me because they would preheat the oven and quite often forget about it and then put 1 burger in there. It wasn't uncommon for them to forget to turn it off either.
So I bought a combination microwave and told them to use that instead of the oven, turned the central heating down to 14°, turned the boiler right down, made sure there were no draughts anywhere and removed some light bulbs as most rooms had 4 or more.
Got the combined usage down to £125 per month. Obviously that'll go up in April though and I'm not looking forward to that.
I'm not sure what else I can do to save energy.
