Last month our gas usage was really really low. I can't remember exactly what it was. We are low users.
This month the heating has gone on and it's got to - 6 yesterday. We'd used £5 of gas before we even got up yesterday.
We are easily using x 5 as much as last month.
Our bill was more than £10 for last month but this month the cost has absolutely skyrocketed.
I think your bill for last month would have been low but £10 is just wrong. £10 a week is probably not an unreasonable amount. (I think this is probably roughly where we are)
This month you should be expecting to pay a lot more because its below seasonal average temperature and last month was massively above.
£50 for this week won't be an unreasonable guesstimate for us. So about x 5 last month. Our thermastat isn't turned up high either. I was bloody cold yesterday.
I think something is probably off with your readings before but it certainly is likely that you'll be using at least x 3 what you did last month even in a best case scenario.
A huge amount of this won't be the meter it will be the weather.
The other thing I ask is whether you rolled off an old tariff onto a new one when you put the meter in. I'm wondering if your rate has gone up.
