Just had an email from Flipper reminding me to submit both meter readings by the 9th of next month.
It's obviously one of these incredibly difficult tasks which need plenty warnings so you can prepare properly for it. Buy the correct tools and protective clothing. Attend night classes to learn how.
I can understand companies trying to persuade you to pay a bill early, much as it annoys. But surely a meter reading should be as up to date as possible?
