I just contacted M&S about economy 10 and got a reply from Octopus. Here is what they said about my meter and their prices. I am Eastern Region for electricity. My current meter has only 2 readings.
I’ve just had a look on the national database, it seems that you did have another meter point for your meter (for the economy 10 set up). However, it seems this has now been disconnected.
I’ve just had a look and your off peak times are between 02:30 – 07:30.
DAY RATE: 18.6375 kWh
NIGHT RATE: 10.0905 kWh
STANDING CHARGE: 22.155 per day
According to E.On who are my current supplier, my off peak times are as follows.
12am to 5am and 1pm to 4pm and 8pm to 10pm ( = 10 hours ).
Can anyone explain the difference in the hours. Is someone telling me porkies ?
I guess I will switch to M&S and trust my meter readings are based on Economy 10 hours.
