Gas Meter Still Increasing Whilst Gas Isolated (Siemens/Landis+Gyr E6S)

You have the right to ask for an independent meter check: your supplier cannot refuse. Your gas meter will be replaced and the ‘old’ meter will be sealed and bagged and sent to SGS: the Government-approved independent testing laboratory. You will get a copy of SGS’ report. If the report shows no fault found, then the supplier will raise a meter change charge.

Before you go down this route it is worth taking a note of the comments made by the Office of Product Safety and Standards re meter testing:

Thanks, yes, i've seen that. For more info, i have the same meter as discussed in this post (and surrounding thread):

<i can't post links yet but its on this site>

and this article:

<a Guardian article from 2014 where someone with same meter got a bill of £20 - thankfully i'm not there, but EDF did try put my monthly bill up to more than £600/month after my recorded usage last summer).

The challenge is i've no idea if i'm always being overcharged or if this issue only happens at times of no/low usage. I've been in the property nearly 5 years and its fairly big, but we have an recorded annual gas usage of around 25kWh. Since the boiler is condensing and we have underfloor heating, i've not been able to work out if the meter usage is correct at the times where the UFH is calling for heat.

Here's some pics - no lever, but a couple of things that could feasibly isolate things - one a yellow cap that is not easily turnable (but I've not tried to force it) and a hex bolt with a yellow On/Off sticker over it (which i've not touched)

The isolation valve and the regulator are on the grid side of the meter. If there was a small leak it would not show as usage on your meter. The meter records the volume of gas that passes through it.

I guess if the leak is very small and outside the gas might dissipate without you smelling it but I would have thought that is unlikely. But I'm just guessing to be honest based on the occasional tiny leak with a caravan gas bottle. The tightness test is very sensitive - I had one done when my new cooker was installed - and will detect the slightest leak so at least that way you'll get a definitive answer.

The yellow knob is in place of the lever, it is a more compact version.  You should be able to twist it so the arrows on the knob turn across the valve which is closed - as shown by the markings on that sticker.  If it is not easily turnable it needs replacing as that is your emergency gas cut off.  It looks pretty clean so should turn.

The only effective way to do the meter test is to turn off the supply before the meter.

The yellow sticker is not very clear.  It's not telling you to turn the hex nut.

It's trying to tell you that if the yellow knob looks like an Ahead Only sign then the gas is on.

If it's rotated 90° clockwise to look like a No Entry sign then the gas is off.

Those bits on the left of the meter are on the grid side (from what i can work out) - are you saying one of those would allow me to isolate the meter? Don't want to touch anything i don't understand, however

For what its worth, i've just recorded another video - boiler off, walk to meter, reading 30103.006, and then over the next 3 minutes, it increased to 30103.023 - not a huge amount, but not something i'd expect, unless there is something funny about this meter I'm not aware of.

I also noticed a new sticker in the box dated 16/11/22, recording metering pressumer 22mbar and relief valve set pressure 35mbar and operated by EDF. I was not aware they had even visited (and my house is gated).

You just twist the yellow knob, that shuts off the gas to the meter / house.

Thanks, now that 2 people have confirmed this is the isolator, i'll give that a try. I've not been too forceful with it to date, so will put a bit more into it.

Anyone got any thoughts on the diagnostic codes on the digital display: b, d, C and rarely E?

I've seen one reference on the web for that meter that states: "The letter D is known as a flag and indicates a problem of some kind."

Hi,

So the deed is done - I turned the isolator - it only went to around 80 degrees from norm but I suspect that's the meter isolated. In the 8 minutes since then, the reading has increased from 30103.160 to 30103.215 - around 0.63kWh.

If it's still going up with the gas off, then you have one of the dodgy Landis+Gyr meters that goes wrong when the battery runs low.  There have been a few that just keep recording gas usage.  On this forum, a previous poster reported that their meter was still going up after the gas fitter had completely removed it from the pipework.

Open a formal complaint, and keep making a nuisance of yourself until they send someone to investigate.  Then insist on a bill refund back to the date when you originally asked for the meter to be checked.
