Just why is impossible to get billed on the 1st or thereabouts of the month. Despite repeated assurances that I will (probably said just to appease me) I get billed at random dates no pattern or reason as to why. Yet another bill sent to me today and the last one was on the 3rd May. Got non response on chat today

Our system generates bills based on meter reading schedules and internal cycles, which aren't always directly tied to calendar dates

Every other supplier manged to bill on 1st of month why do EON fail with this

Eon seem to bill me at will yet I can only request SEG payment every 3 months seems unfair.

Some suppliers seem to mess around with irregular billing calculation dates and/or payment dd day, making it more difficult to keep on top of whether they owe you. At this time of year, there seems to be usual practice to try charging people as much as they can get away with rather than as much as you have used. Best defense if worried about that is to compute your own cumulative "bill estimate" to exactly 1st of every month, which you can plot cumulatively.
On the same XY chart, then plot the cumulative £ at dates billed to by your biller "supplier".
Then on the same XY chart, plot the cumulative £ paid to your supplier, at the dates of the outbound transactions from your bank.
Phew! that is a lot of stupid work to check whether the office who did electricity bills had cheated. You shouldn't have to bother, but if you did, you should get three lines which overlay, regardless of irregularity of billing dates. If lines diverge then something isn't right.

I regard £ as a pointless makework unit which does not tell much about how your efficiency improvements for bill-saving at home are doing. No point learning your £ per day because the price changes every three months, but your kWh/day are useful and can be compared to previous years. I prefer to press the button on the in-home-display to show kW ('kiloWatts') and kWh ('kiloWatt.hours') and to use a 3-pin plug in power monitor because then you can learn where the power is going and how various appliances compare to one another. For example my new fridge uses 77 Watts and 0.4 kWh per day, by comparison to the old fridge using about 90 Watts and 0.6 kWh per day.

My billing date is indeed 1st of month as I specifically requested that. It took 2 attempts to get it right though!

after my own freezer saga I too advocate the use of a plug in power monitor to test the consumption of individual appliances. My replacement freezer paid for itself in about 18 months such was the greed of the old one.

@BruceM - Is there possibly a bit of confusion between the terms "billing date" and "statement date" (the date the usage totals have been calculated/read)? Your screenshot showed the dates the statements are produced - clearly they do vary a lot.

In my case my billing period (the date shown on the physical bill) is always from 21st of previous month to 20th of current month, and the bill doesn't get produced until the usage statements have been prepared.

My statements are generally produced around the 22nd, but can vary by a number of days - most often the 23rd or 24th but can be a lot later.

Sometimes the gas & electricity statements are produced on separate dates, this can be way beyond the normal date - last month the gas was 22nd April and electricity was 25th April. Looking at the raw electric smart-meter data at the time (I'm on Next Drive using ½ hourly readings) there appeared to be some kind of glitch where the readings weren't actually available until the 25th, so I guess they didn't want to produce the bill until that month's data was complete.

Generally, the availability of the raw meter data seems to have a day or so lag between the current day and the date the meter readings become available. So I guess this is why my statement can only be created on the 22nd, for the bill being produced for my billing period up to the 20th.

This lag is also (presumably) the reason the EOn app is always a couple of days behind in showing the usage graphs - maybe a DCC restriction so nothing to do with EOn, though they always get the blame for it.
