Poor. Inefficient. Cannot put readings right.more interested in getting you to have a smart meter. consistent harassment over having one. Incorrect average usage for gas for year due to mistake by them which resulted in a £2000 + gas bill ot one month .therefore average reading is far to high which they say cannot be changed.get bills for a week and only for gas.try to put up direct debit by £50 even though I am £900 in credit
Could go on.but it's a waste of time they take no notice
