Economy 7 / Day-Night meter · Ireland
Your Day register has been frozen since your last known good reading — everything you use is currently passing through the (cheaper) Night register. This compares what you're actually being billed against what a corrected day/night split would cost, and checks your supplier's estimated bill against your real readings.
The last reading before the meter got stuck — the shared starting point for every comparison below.
Rates apply to every scenario below. The day-split % is your estimate of what a working meter would actually show.
Log what the meter really shows. Leave Day blank if you couldn't read it — it'll be assumed unchanged (frozen) since your last reading. Register rollover (99999 → 00000) is handled automatically.

Log each estimated reading from a bill. It's compared against your real usage for the same date range (found by interpolating your actual readings above) — so you can see exactly how far off the estimate is, under both the current all-night billing and a corrected split.

Your real cumulative usage against the supplier's estimate, and how the actual vs. corrected cost gap grows over time.
