Hi again everyone.
Thank you all for your comments and advice. It seems that having been on an economy 7 set up when the flat was built, the meter is still seen as that when Look After my Bills looked for comparisons. I called her current - and quite new energy company and they have now moved her to a different tariff so she should save about £30 per month. I hope so. So please, everyone else, make sure none of you are in this situation. Mum does like it extremely warm, as she is sitting still most of the day. She does wear plenty of clothes, but it's not comfy to be bundled up with so much that you're just not comfortable, so as long as she can afford it, I wouldn't try to turn things down or suggest she wears heavier clothing. Someone said I made no mention of a washing machine - there isn't one, as there's a communal laundry room for that, although I do it anyway. It seems like we all need to be as clear as possible with these things, as it's easy to end up being charged incorrectly for one reason or another!
It’s been a while so I will start us off…….whats for supper and why?
