IHD and Meter says I’ve used £2300 of gas this billing period

As per the title my IHD and gas meter are displaying a stupid amount of gas usage (£2302)for the first three weeks of this month. (My total gas usage for May was only £16) 

In fact £2000 would be approximately 4 years gas usage for my two bed semi detached bungalow. My online account details show a figure which is as expected of £5.13 gas usage for this month. 
 

why such a discrepancy ? 
also my online account shows readings of 5719 have been sent on 20th 21st and 22nd June

yet my Ihd and meter display 63769.440 under meter reading.

i tried querying with online chat only to be told that consumption varies and basically the meter is a smart meter and will be correct. 
 

Fair enough if the meter is sending in accurate readings,  but if Ovo were to manually read my meter or ask for a manual reading they’d be getting the much higher read. 
 

I did ask if the reading on the IHD is converted at some point to the reading they use their end but was told  no. 
 

My electric meter readings coincide with what I see on my account it’s just the gas which is so out. 

Just to add some more context my electricity supply was interrupted for several hours on 20th June as my supply was looped to my neighbours, and needed unlooping because of alterations to their property needing a meter relocation. During this the main fuse to my electric meter was removed by National grid while the works were completed. 
I wonder if it’s possible that the interruption compromised the information stored in the gas meter as I know the gas and electric meters do communicate with each other 🤔

I have raised a complaint for Ovo to investigate as I was getting nowhere with online chat being told there was nothing the rep could do and no point escalating as I’d be told the same by someone else. No attempt was made to understand my concern nor any realisation that a £2300 consumption in summer for a domestic property where the only gas usage is when I turn a hot water tap on is totally unrealistic anyway for a 3 week period, even saying check my previous bills, just resulted in the same reply that ‘you can’t expect the same consumption every month and there are standing charges too’
 

Just wondering if anyone else has had such discrepancies between the meter reading displayed on their IHD and meter compared with the readings being sent to Ovo ? 
Thanks

UPDATE

Just after my last post I had a call from OVO in relation to my e-mail complaint. Basically they are re-setting things their end and if it’s not fixed send an engineer. They’ve assured me they are receiving correct readings from my meter but the displays my end are incorrect.

 

Thanks again for all the inputs 

If the information on your In Home Display (IHD) seems incorrect, then there could be an issue with the IHD itself, or with the smart meters at your property. If in doubt it’s always best to contact our Support Team, however this article may help you determine whether the issue is the IHD or the smart meters:

Disclaimer: I have no personal experience of gas meters, smart or otherwise.

 

The power interruption can have had no effect on the gas meter; it’s generally regarded too dangerous to mix mains electricity and gas. 

Where do you see ‘£2302 usage’ on the gas meter? A photo of it would help. 

The reading you quote - 63769.440 - is very close to the kWh equivalent of 5719 m³. Have another look to check what units are being displayed (the meter can only give an approximation of the kWh amount because it can’t know the calorific value of the gas it’s metering).  

The IHD may have been upset by the power outage, but if it hasn’t come right in a few days, ask Support for help. Meanwhile, you should be able to rely on the online account for an accurate picture of what’s happening.

Hi ​@Mikep , when you say that

As per the title my IHD and gas meter are displaying a stupid amount of gas usage (£2302)for the first three weeks of this month. (My total gas usage for May was only £16) 

 

How are you seeing any cost on your meter? The IHD is not used for billing so as long as the meter reading on your meter hasn’t suddenly jumped then your bill shouldn’t be affected.

There are ocassions when a very low usage on the gas meter can affect the IHD but again, as the IHD isn’t used for billing it shouldn’t make any difference.

Thanks for the reply 

this is why I asked the rep whether I had to convert the meter reading on my ihd show KWh into another figure and he said no that was the meter reading figure 

then obviously seeing the £ figure triggered my concern . 
attached are photos of my current display

under meter readings I can only see the kWh figure and not cubic metres.

 

Thanks again for your explanation. Certainly more helpful than I had from online chat.

Pressing OK on the IHD shows account information (ok) pressing ok again shows Bill so far this period , first for  electric then pressing the thunderbolt/flame button shows gas.

Photo attached of IHD which is clearer than the meter but I get the same info showing.

The  customer service rep told me that was the cost of the gas I’ve used so far for the month . Well moth actually, which I guess was a typo.

Thanks. That’s a fault I don’t remember seeing before, and I can’t imagine where it comes from. The IHD is supposed to receive and display m³ figures for gas. The gas proxy (a device inside the communications hub on top of the electricity meter) is clearly receiving the right m³ data from the gas meter so they can be sent to OVO, so it’s a mystery why the IHD is getting kWh figures from the same meter. It also looks as if the IHD is using its own internal systems to work out consumption figures in £ as if the data it was receiving were normal, which they obviously aren’t.  

I’d suggest contacting Support again, using the webchat option. You’ll then be able to upload the images so they will be added to your account and can be scrutinized by someone who knows about IHDs.

Meanwhile, please upload a photo or two of the actual gas meter. You will have to touch a button to light up the screen; repeated touches should display more information than just the kWh figure.
