Why is my overnight usage shown on my smart meter In Home Display (IHD) so high?

My smart meter was installed yesterday at 7.40 this morning my electric usage was 42p & gas usage was 28p. Even taking into account fridge/freezer, broadband, TV’s on standby overnight 42p electric seems high. The gas at 28p is a bigger mystery as no gas was used overnight (heating is off at the moment). Does some of the cost include a daily standing charge? Can anyone shed any light on this please?

It’s worth factoring in your daily standing charges when checking the costs showing on your smart meter In Home Display (IHD) in the morning. These charges are usually added to your daily energy costs around midnight each day and will vary depending on the rates on your current plan.

 

The best place to check the standing charges which apply to your current plan is the ‘Plan’ page of your online account or OVO app (download for Android or iOS):
 

Exact appearance may vary

 

You can also view your smart meter usage data here too, by heading to the ‘Usage’ pages. Check out the guide below for more help with this:
 

 

 

Still worried that your overnight usage seems high with the standing charges excluded?  Bear in mind some appliances (like fridge/freezers and TVs on standby) use electricity overnight.

I think it includes the standing charge, like 27.4p per day... that'll do it...

Plus VAT that's 28.77p per day.

Tadaa :)

(a friend of mine and his partner went away for 6 months and switched everything off. Like Everything... When they got home the energy monitor showed that 28p per day on the elec. She properly went off at him for leaving something on, until they worked it out...)

 

As suggested by the user above, it’s worth factoring in your daily standing charges when checking the costs showing on your smart meter In Home Display (IHD) in the morning. These charges are usually added to your IHD usage balance at midnight each day and will vary depending on the rates on your current plan.

Still worried that your overnight usage seems high with the standing charges excluded?  Bear in mind some appliances (like fridge/freezers and TVs on standby) use electricity overnight. You may also have night time storage heaters or an immersion heater on a timer, and these sorts of appliances can use a lot of energy in the off-peak hours. If you’ve got storage heaters and/or an immersion tank, then you should be on an Economy 7 tariff:

Hi,

I’ve just moved into a house with smart meters for the first time and I’ve been monitoring the IHD for daily costs. What I can’t get my head around is what time the standing charge is added to it? Every morning the electric is on 80p, even when turning all the trips off at 11pm the night before, so I’m guessing the standing charge for electric is added first thing in the morning, even though the 80p doesn’t match my cost for standing charge even with the 5% vat. Gas is always on 10-15p so that’ll be my boiler cutting in for those 8/9 hours

My gas usage read 45p at 23:50 and just after 1am I read the previous days usage and it was at 98p so that makes no sense even with my 32p standing charge plus any vat?

Any help greatly appreciated!

Jon

Great question this one, @GeordieJon.

 

As you’ve spotted your daily standing charges will already show on your In-Home Display (IHD) when you check your usage costs in the morning. These are added around midnight every day. 

 

You mention that the figure shown is higher than your standing charge, as mentioned in this similar thread, this may be down to the energy used by appliances (such as your fridge/freezer) which are running overnight.

 

Have you been logging in to your online account or OVO app (download for Android or iOS) to check the usage data shown here too?

Hi Jess, thanks for the reply.

I understand the electric standing charge must go on at midnight but sometimes when I wake up at 8/9am my gas is only on 15p, which is lower than what my standing charge is at 32p

as I said before it was every so slowly creeping up throughout the day and nearly at midnight my gas showed 45p, so I expected the standing charge of 32p to be added in a few minutes. I waited until it reset after 12oclock and then went on the previous days usage and it said 98p so that doesn’t make sense either 

The meter readings are correct and my bill in the app so far looks to correspond with those readings, but the IHD seems to be adding and subtracting prices on both gas and electric whenever it feels like it.

This is strange, @GeordieJon.

 

I’m wondering whether your gas daily standing charges are being shown under the electricity charges. This has been spotted by other forum users on the thread below.

 

 

Always worth viewing the daily usage costs on the device as more of a guide than your exact billed amount, Any inconsistencies here won’t impact how your charges are calculated on our billing platform so we’d recommend checking your balance and ‘current billing period’ figures on your online account or OVO app (download for Android or iOS) for a more accurate view.

 

Sorry for any confusion - Hope this helps.

My smart meter was installed last month (EDF)   this morning and every morning  my electric usage is 80p & gas usage doesn’t work as yet, Even taking into account fridge/freezer, broadband, TV’s on standby overnight 80p electric is very high Does some of the cost include a daily standing charge? Can anyone shed any light on this please is the standing charge added on through the night my electric every single night from 12 midnight till 8am is always 80p and most days between 8 am and 4 pm it’s rounder bout the same 80 give or take a few pence

Your house will have a base load, which is the electricity used by appliances that don't get turned off. You can see it by changing the display of your IHD (the in home display connected to your smart meter). It will probably be a few hundred watts (w).

I suggest you have a look at how much you're using (in w) just before you go to bed when you've turned off the TV, lights etc. Check again first thing in the morning. If it's more than about 200w or 300w you might want to check for appliances that are using too much electricity.

Hi @Ray Sis 

That is a very good question. 

Your In Home Display includes standing charge and VAT in the cost information

The costs on the Usage page on the OVO website and app don't include the standing charge or VAT. You would have to check with EDF exactly how their website and app worked. 

You do have to be careful when looking at energy cost information.

Let us know if you have any follow up questions.

Can anyone tell me why at random days and times normally early hours of the morning my energy consumption electric almost quadrupled for 2 hours when nothing is actually being used and everyone is in bed? It keeps happening for 2 hours for 2 days about every 5th day? Tia

Hi @Alibongo ,

To be honest, that’s a very difficult question to answer. Only you know exactly what you’ve got around the house and we don’t have X-Ray vision so it’s really difficult for us to advise based on this information alone. I think @Jeffus and @M.isterW are pretty good at figuring this out though, so I’ll ask them to stop by.
