Using gas whilst away, how is this possible?

So whilst i was away the My OVO app showed i was burning 30p a day of gas. Now i use NEST so i turned the thermostat to off before going

I have no other gas appliance so unsure what to-do, i have OVO smart meters so could they be sending false data?

I was interested in your post as I have also been looking at my gas consumption when I am not at home since my Smart Meter was installed.

On days I am not in the house for a whole 24 hour period, MyOVO shows that the Gas cost for the day was £0.33. This seems to be consistent across the month.

This is made up of 28.77p standing charge and then 1.4 kwh of use @ 2.66p per kWH.
So 32.494p in total (I guess My OVO always rounds up in the graph).

So I was curious as to what is using the 1.4 kwh of Gas.... I have two Gas Appliances, a Vaillant Combi Boiler which does hot water and heating and a gas hob.

Now I know for sure the hob wasn't turned on, and I too have a Nest system so I know that the heating wasn't turned on at all (from the history in Nest).

So I have three theories
1) The Boiler occasionally uses a tiny bit of gas? Some sort of maintenance safety feature...
2) I have the worlds smallest gas leak
3) The meter is creeping when no gas is being used

I plan to test these theories by switching the boiler off completely and seeing if I get the same result next time I go away.

So just an update on this now that the summer is here!

The conclusion, my meter is definitely not creeping forwards on its own and it is the boiler that is using gas, even when it is not being used!


So even though I have a combi boiler, with no hot water tank and I know the heating is not being used, it still seems to used around 1kWh of Gas per day. Next time the annual service is due I will ask the plumber to see if he knows why.

So in the summer I can turn it off completely before I go away (no pilot light so easy to switch off and on), but in the Winter I will probably leave on when away as the thermostat will cut in if the temperature drops to prevent the pipes freezing and it is nice to turn the heating on when you are on your way home!

 

 

It’s very rare for smart meters to over-clock your usage, if you’re concerned about the accuracy of your meter see this guide for how to test for a faulty meter. If you’re looking at your online account, make sure you’re looking at data using meter readings, and that it’s not been estimated.

 

It’s also worth bearing in mind that even when you’re away from home your daily standing charge is still applied which might help explain the usage costs you see on your online account or OVO app (download for Android or iOS), whilst your home is empty.

 

If you are noticing minimal charges over the daily standing charge it’s possible that your boiler/pilot light uses a small amount of gas, even when your heating is switched off.

Hey @MrsSB 

Sorry you’re still experiencing issues with this.

 

Do you know if the meter reading schedule is set up at once daily, or is it set to send them every half an hour? It may be that the reading only comes to us once a day and so the system may be estimating the usage in between those actual readings each day. Our Support Team can check this for you, and if it’s not already set to half hourly, they can get that changed for you.

 

We also have this forum idea, which is focused on making this sort of action, something that customer would be able to change themselves: 

 

I know it must be frustrating trying to get this resolved, but as we have no access to accounts here at the Forum, we won’t be able to provide you any specifics on your account & usage.

 

There is a test called the meter accuracy test, this is when the gas meter is removed for testing. They would replace it for a new one when they remove the meter, if they found that the meter wasn’t faulty there would be a charge for the appointment, so it’s always worth ruling out all of the gas appliances first to be sure it’s not one of those. 

 

Please do get back in touch with the Support Team about this so that they can look into it.

Our meter sends readings half hourly, it appears to be sending readings when no gas is being used, eg when we are in bed and everything is switched off, but also recently during the day when we are in the house and know nothing is being used.

 

So if our meter is faulty we have to pay to have a new one fitted? Really? Why?  We haven't caused the fault!!!!

 

As for ruling out gas appliances there are only 3:

a gas fire which has not been turned on for over a year - I think we'd notice if that suddenly switched itself on and we certainly haven't smelt any gas leak from it.

A hob, which is around a year old - again, I think we'd notice if that to was switching itself on, our if it was leaning gas, and finally

The combi boiler - again, we'd hear if that was switching itself on, we've checked the settings and it isn't set to heat water apart from on demand, heating is set very low and has never come on overnight, even in winter. No smell of gas in the cupboard where boiler is located. 

 

So unless there is some other way to "rule out appliances" we've pretty much done that already. As this problem is intermittent, ie happens every day for a few days, and then not at all for a further few days, and so on and so on, a leak is unlikely as, presumably, a leak would be continuous until it was located and repaired, I assume it wouldn't just have a few days of and then return??? We are getting absolutely nowhere with Ovo, no-one wants to help or even suggest any way for us to get help, we've resorted to turning our gas off at the meter as we're so concerned about charges being made for gas we are not using.

Hi @MrsSB 

 

Thank you for all of that information.

The test in question requires the meter to be removed in order to test it. If they find that the meter is faulty during this, you wouldn’t be charged, but if they found that the meter wasn’t faulty, this is the only reason you’d be charged, only of the meter wasn’t faulty.

When they remove it to be tested, they would fit a new one anyway as they can’t refit the same meter. 

 

The best thing to do will be to contact the Support Team to discuss this as we don’t have access to your account here at the Forum.

Thank you. Your last response actually said "if they found that the meter was faulty there would be a charge"  which is why I queried it.

 

We have been in touch with Customer Services, and also have emailed Ovo's CEO. We have had numerous phone conversations, and numerous emails, none of which have been any help to resolve this matter. In fact yesterday our gas usage shows charges for mid morning when the boiler, hob and fire were all switched off, we were out of the house, and the gas was actually turned off at the meter!!!  To our simple minds this indicates a meter fault but I expect Ovo will try to wriggle out of it & say it's something we're doing.

@MrsSB I feel like some context on this meter accuracy process might be helpful to you. 

 

Most people who have higher than expected actual usage benefit from ruling out the most common causes: something to do with their appliances. Most meters tested for a fault are not faulty. For these two reasons we recommend anyone rules out other factors before booking a meter accuracy test. 

 

As you might imagine, a meter accuracy test that is free no matter what the results would not be scaleable for an energy supplier. After all, nothing to lose in getting it tested right? Instead OVO aims to give you as many ways to rule out alternative causes first, and helps you book in the test if you’re sure. If the meter is faulty, the test is free and your charges are recalculated. Otherwise you’ll be charged for the appointment. 

 

In your case I still think there’s a chance that your meter has intermittent communication with OVO. Even if we get a daily reading, perhaps we don’t always get half hourly usage data. If that’s true your half hourly graphs will be partly estimated, just like how you describe which sometimes shows the overnight usage and sometimes don’t. So I wouldn’t use the graphs as the only justification to book a meter accuracy test. It’s far better to look at the total kWhs your meters have clocked, shown in your monthly bill, having checked that you’ve had daily readings added for those dates. If the kWh’s are much bigger than you expect, that is something worth exploring. 

 

Hope this helps,

Tim

That hardly explains why on 2 consecutive days, where actual usage was identical apart from an extra boiling of a kettle on the hob on the 2nd day, the usage recorded on the 1st day was 4.84kWh and on the 2nd day 22.92kWh.  So the boiling of a kettle added 18kWh to our usage, when the 1st day's 4.84Kwh actually included 2 kettle boilings? 

It seems to me that Ovo representatives will suggest anything rather than about the just could possibly be a problem with their equipment.

And @Tim_OVO  we're quite prepared to pay to get the meter tested/replaced as we are not stupid enough to believe that Ovo will admit to there being a fault and we won't expect to get our money refunded. Funnily enough, most old people have seen enough of life to realise that this is how things work.

Hey @MrsSB 

 

Would you be able to upload some screenshots on to the Forum, on this thread, so that we can look at the readings? As we don’t have access to accounts we can’t see any of that information, so if you could attach some photo’s we can see what you can and try to help you more where we can.

My heating and hot water are currently turned off but there’s a charge for gas on my account. Does anyone know why this might be?

Your meter is showing some gas use in the evening. That pattern suggests it isn't a leak. Are you sure you don't have a gas appliance that's switching on at 7 or 8pm? Some combi boilers have a pre-heat function that runs even if you don't use any hot water. Could it be that?
