Help with reading a meter bill

[druid77]

I have been asked to help a friend understand their electricity bill. A task I find challenging as I don't understand it myself. Note that at the moment I have not seen the meter installation, only the bill and I have attached a redacted version of the relevant page
My questions are

1) Can you have 2 different supply numbers for one meter?

2) Do meters exist that have three payment rates of Flat/Day/Night. I was under the impression that you had either a flat rate meter or an “economy 7” meter with day/night rates
Note this is a small one bedroom housing association bungalow (with solar panels fitted), a single occupant and no gas so all power is electric. I assume heating is night storage heaters but will check at next visit. This bill is July to September so hopefully little or no heating charges.

3) Is 41 kWh a sensible number for night rate for 60 days (presumably water heating) . Less that 1 kWh/day seems very low to me and I wonder if the water timer is mis-set heating the water on the day rate.
(And yet the top part of the bill seems to be charging at 11.06p/kWh which is closer to the night rate than the day rate. and includes 362kWh for 60 days, 6kWh/day which seems to me more sensible for water heating)

4) Does the suppliers yearly kWh estimate of 2262 day and 1638 night seem logical. I would have thought anywhere with Night Storage Heaters would use more kWh overnight. But I have never had NSH so am talking from ignorance.

Any help for me to explain this to someone else would be very much appreciated.
Regards.

That is a dual rate tariff.

First block is the night time usage and the second block is the daytime usage.

As they have 2 separate meter numbers and 2 lots of standing charge, it looks like it is a very old install that does have 2 separate meters. You would save some money by having those meters swapped for one dual rate meter and then there would only be one standing charge.

The part that looks odd is the Supply numbers are different but the Meter numbers are the same looking at what is annotated on the redacted bill which is confusing
The top part of the bill is clearly a night tariff only meter and the lower part is a dual tariff meter

I would suggest the OP posts a picture of the current metering and consumer unit arrangement I suspect that the night tariff only meter is operated by a teleswitch or timeswitch serving storage heaters so it might need some wiring mods to move over to a single meter and save a few hundred pounds a year on the standing charge

I wonder if this is a reconfiguration of the old Total control system that did indeed have 2 meters, one being single rate, one being dual rate. As above a picture of the meter(s) would help.

Just re-read the OP and solar panels are mentioned so is the top part of that bill for an export meter given that no annual usage figures are given

A photo showing the meters might help

That is correct

The top part of the bill is clearly a night tariff only meter and the lower part is a dual tariff meter

Will hopefully be round there Thursday of this week, so will try to get a picture and a bit better understanding of how the user thinks they are using electricity

Looking at the meters and the bills isn’t really giving enough information

Apart from night storage heaters how is the hot water heated?

How many heaters? Are they all storage heaters or the newer LOT 20 units ?
