@RadioFox @snic I have the answer to this now, so can clear everything up for you:
The reads have been added as part of the process of changing you to Market Wide Half Hourly Settlements.
What is the Market-wide Half-Hourly Settlement (MHHS) Programme?
The MHHS Programme is a major initiative in the UK electricity market to move all electricity meters to a half-hourly settlement basis. This means that instead of relying on estimated consumption or annual readings, energy consumption data will be recorded and used for settlement every 30 minutes.
What is the primary objective of MHHS?
The primary objective is to improve the accuracy of settlement - the process of reconciling the electricity generated with the electricity consumed. Currently, Smart electricity data for settlement is based only on monthly readings. This allows suppliers to see how much energy has been used but not when used.
Moving towards half-hourly settlement will help suppliers forecast the energy customers need more accurately, and buy electricity to meet that need in advance. As a result, they’ll only buy the necessary amount of electricity for their customers, and encourage customers to shift usage to cheaper times of the day.
This will help stabilise the grid, reduce carbon impact, and ultimately lower the cost of energy for UK consumers. Better forecasting will allow purchases from renewable sources rather than expensive, carbon-heavy generators.
If you have traditional non-smart meters
If you don’t have smart meters you’ll still be changed to MHHS. You won’t notice any change but, if you do ever have smart meters fitted, then the smart meters will provide the half-hourly settlement data.
@RadioFox @snic - as part of this change, a reading had to be entered on your accounts on the day the change took place, and the reading was entered so that it approximately fell in line with your reading history. No engineer has taken this read - this is purely administrational. It won’t happen again, and won’t make any difference to your billing.
Apologies for any alarm or confusion caused, and I hope this clears everything up.
