What’s the actual timescale for ensuring that user readings are used rather than estimates ? I read that you estimate if the readings are more than 4 days early
e.g. I started on the 23rd. I plan to send you a monthly reading on the 23rd following. When will you issue a bill / claim a payment ? When do I need to send you a meter reading to ensure that it’s used ? On the 19th is clearly too early.
