Hi - we have just had £7k taken from our bank account for gas. It is an estimate. We are on holiday so it has cleaned the account out for spending. Normally it is about £1600 for the year.
Checked online our estimated use for the year ahead is 500,000 kWh. This works out about £90,000 on our variable tariff. Does this look like a mistake to you or will bills go up that much? Cannot pay it obviously. It is a large house with 5 bedrooms, though we do not waste heat. Bit shocked this can happen actually.
