Astronomical Electricity Bill

Your tariff is entirely unsuited to a wet electric central heating system. About 95% of your usage is during the day, so you are paying a premium of around 300%. Switch to a single rate tariff. It will still be expensive, because this system always is, since it can't take advantage of cheap night rates.
Unfortunately you will still have to pay for the energy already used at peak rates.

If you read the user manual, you will see this unit is intended for use on E7 (or other multi-rate tariff), particularly for DHW.

I'm not sure I would agree with the estimated annual usage figures provided by the supplier. The OP says they have used 7651kWh in 202 days (Rate 1: Day) and 651kWh low rate over the same period.

I struggle with these figures as I would expect a higher low rate usage if the user is making optimum use of E7 for DHW
Also, once that is corrected, I would not expect the central heating will be used much, if at all, for the remaining 163 days of this year

Hi Everyone for the response,

I have calculated the usage and here are the results:
From 14th of Sept, I used 7651kWh in 202 days (Rate 1: Day)
Over the same period, the Night Rate is 651kWh.

I am on E7 rate from EDF as well.

I've compared my usage with our landlord who lived here before us and it was less (~650kWh/year for both day and evening). They do switch off their heating and water during the day, but i am not sure if that could be the cause for an increase of 20 fold in consumption.

We do keep the heating and water on during the day some times. Thermostat is set to turn to 15 degrees during the day (08:30 to 16:30). During the evenings, it is set to 23.

Hope you all can shed a light on what is happening?

I do struggle with these figures somewhat for the reasons explained above.

However, as you have a smart meter, you should be able to monitor what you are using and when.

I've got an all electric heating system and most of my consumption is in the winter dropping dramatically in the spring & summer.

We could possibly benefit from E7 in the summer by heating the water overnight but we'd also have to use all our appliances overnight as well.

There is no way that E7 would be of any benefit during the winter as the heating would be on during peak rate times.

The flow boiler would have similar characteristics, it'll cost a fortune to run on peak rate leccy (ie when the heating or hot water is on during the day and evening), the only benefit you'd get from E7 is by heating your hot water and using your appliances overnight, especially in the summer so you might as well get the cheapest single rate tariff you can.

If you cant understand how it works and what it's using and when, there isn't really much any of the rest of us can do to help. You've used loads of expensive leccy already, you need to start reading your meter more frequently and sort it out or just continue paying lots in the future

Jyan - you say your estimation is different to what you've been billed? Isn't, therefore, the bill simply based on incorrect meter readings. If the start and end readings are different, tell EDF, and ask them to correct the bill.
