Gas meter is clocking incredibly high usage with no one in the house?

Nope unfortunately don’t fit into any of the catagories.. siggh :) 

That doesn't look right if you haven't got your heating on. I assume your heating isn't on very low permanently. 

Given they are 30min readings they won't be estimates. 

Even if you have a hot water tank heating the water constantly or a pre heat function etc on your gas boiler, you wouldn't expect to see that usage every 30 min and that total over a day. 

I strongly suggest you get a gas engineer to check you haven't got a small gas leak somewhere asap.

We had a small gas leak once, so it can happen. 

Hi @Jeffus thank you so much for replying so quickly.

if there was a leak would you expect to see constant usage throughout the day? For example the same day I showed above there was nothing clocking up some hours earlier in the day when there were people in the property. It doesn’t seem to make sense at all with what / when we are using our hot water

So that does look different. As the other screen shot had usage every 30min.

I would still suggest getting a gas engineer to check then.

To see if there is something wrong with your gas boiler firing up when it shouldn't. 

I would be very surprised if you used that much gas on water heating alone with no central heating.

Do you have your gas appliances serviced every year. I strongly recommend it. 

You mentioned that you're in a block of flats? Is your meter in your flat or in a communal meter cupboard? I'm wondering if the meters are mixed up so you're getting someone else's readings.

Hi @M.isterW yes our meter is located in a cupboard outside on the street with all the other flat’s meters

You can see the details ovo hold for your meter here.

You could check this against the actual meter. 

You could also go back over your old bills to see when the issue started to occur and see if the meter details flipped.

If anyone in your home qualifies on a permanent or temporary basis you could try signing up to the Priority Service Register.

You can sign up online.

Then you can ask for a free gas safety check from OVO

Just looking at a few other things and noticed this might also help on checking if the meter is correctly identified for your account 

Thanks so much for your suggestions.

@M.isterW i have checked and the serial number in our account matches the serial number on the meter itself so nothing looks odd there

@BPLightlog thank you for sending this over we’ve have done some tests a few times and mostly found that it shows there is some gas usage even with all t electric supply to the property (and therefore the gas boiler) turned off 

we switched the boiler off at the mains yesterday at 2.30pm and haven’t switched it back on yet. This is our usage graph for yesterday evening

We’re not sure what to do next. OVO have suggested getting someone out to do a meter accuracy test but this is at the cost of £157 to us and only gets refunded if an overclocking issue is found which I’m not convinced is the issue - if it was overclocking wouldn’t the inaccuracy be consistent? Also this can take up to a month to arrange an appointment, up to 2 months to complete the test and then up to 3 months to get a refund of any overcharges - so we are at the mercy of whatever the meter decides to charge us for at least the next few months which is likely to be extortionate, again to clarify without even being able to put our heating on. We are at such a loss!

Matching serial numbers doesn't mean it's your meter. It's unlikely that they've been mixed up but you could check by turning everything off (completely off) and checking that the meter reading doesn't change over a period of time. Then turn appliances back on and check that the meter is recording the usage.
