Your thoughts on electricity bill?

There does indeed seem something rather wrong

You indicate your day reading in Feb was 1248
And the day reading in June was 2125

That's a difference of 877kWh

Yet you appear to have been charged a total of 905kWh in that time
(234+251+217+203)

Similarly for night rate:
Metered: 1639kWh
Charged: 1220kWh

Please provide your annual figures, and let's get you switched to a decent supplier sooner rather than later

Thanks everyone for your replies! So I think I am definitely using too much... my to do list:
-post some photos of my water heater on here to see if I can manually change the timer/temperature without getting a man in.
-check with Bulb that I'm reading the meter correctly!
-if all else fails and I am just using a lot... might have to splurge on a new oven and fridge in an effort to cut it just a little bit and then freeze throughout Winter

Bulb have assumed my annual consumption as 6700kwh (£798)

And re. area, I'm in SE8 (London)!

Investigate cutting down the water tank temp - I see you have already got this down to look into.
As a temporary step, turn both switches off and only turn on the top one - the one that is currently off, probably - for 15 minutes before showering then turn it off after the shower, and boil a bit of water in a kettle for washing up if you do it by hand.

Do you use the oven a lot - if so, does the temp light stay on permanently while it's in use?
If it is then this could well indicate a faulty thermostat gobbling up power as the elements never cycle on and off while heating the oven, they just stay on, and replacing this should cost a lot less than a new oven.

Based on that usage (ca. 57.7% night rate it appears), how would you like to save over £50 per year without changing anything (except who you pay)? :money:

That's probably even more than the bribe you were offered to join your current supplier in the first place
... and remember such a bribe would have been a one off credit only. I'm offering you a saving of over £50 per year, every year! (based on current prices)

Here is the kwh usage from my statements:
Feb-March:
Energy (day) 234 kWh @ 14.56 p/kWh
Energy (night) 379 kWh @ 7.10 p/kWh

March-April:
Energy (day) 251 kWh @ 14.56 p/kWh
Energy (night) 391 kWh @ 7.10 p/kWh

April-May:
Energy (day) 217 kWh @ 14.56 p/kWh
Energy (night) 261 kWh @ 7.10 p/kWh

May-June:
Energy (day) 203 kWh @ 14.56 p/kWh
Energy (night) 189 kWh @ 7.10 p/kWh

Please show which are indicated and which are estimates.

Unless the oven's faulty, it's probably not going to give you significant savings. And if it was faulty it would be burning all your food?

Judging by your use at this time of year (equivalent to 4750 ish per year), you'll struggle to stay anywhere near 6700.

Hi all

Anyone know how/if I can alter the temp/time?

Feb-March and May-June are my readings, the others are estimates.

If there is a temp adjustment, it'll be under that yellow cover and that's a job for an electrician.

It doesn't look as if you have any time controls. The left hand switch powering the top "boost" heating element could be replaced with a Horstmann Electrisaver E15 or E30 push button timer switch. It would prevent the boost element being accidentally left permanently on using peak rate electricity. But you probably don't use that much?

As for the other switch controlling the main (bottom) heating element, we have to assume it's connected to the off peak only output from your meter and is powered for 7 hours a night. There are some nice Horstmann E7 immersion controllers but I don't think they're designed to be connected to the off peak circuit that's only on for 7 hours a day. Ideally, you'd need an electrician to swap that feed back to the 24hr output from the meter, then fit the timer to give you full control of when water heating was happening and for how long.

That said, I have no idea how wasteful it is to get the water to maximum temperature at 1am and then top it up if it cools down a bit during the remainder of the 7 hours until the E7 output shuts off.

It goes without saying that if you're going away for more than a day you'd switch that night switch off.
