It’s massively regulated, so they won’t tell you the leak is on your side of the meter if it’s not. Because if you were to report that to, say the HSE, that would be a massive issue.
I think a Gas Safe was jailed(?) fairly recent for doing a half arsed job and then there was an explosion. These incidents are investigated in incredible detail.
They are also regulated on timescales of emergency engineers arriving on site. 1-2 hours is usually the max (depending if smell of gas disappears when isolated at ECV).
I think what we're missing here is that the OP had a massive weed grow and has reversed the meter for a while.
I remember a previous discussion about brass stilson wrenches IIRC!
Hahah...a gas-powered steam-punk weed grow! I'm not that imaginative 😉
Sorry for any confusion...after the electical re-wire, the electricians had to report the mains electric feed where it enters the house as there's no, or hardly any earth on it when they tested, if I recal what they were saying correctly. not a huge supprise as it looks ancient and looks pretty rough.
It was the gas issue I noticed after they had left. I can't smell any gas, but I doubt I'd be able to given how slowly the meter is turning.
Anyway my test meter arrived, after turning the gas off yesterday and overnight, I turned it back on and tested..nothing..but then if gas is escaping i think I'll have to give it more time as it's such a timy ammount.
I know the meter is working as after doing the calibration cycle (outdoors), I tested it by expelling some gas from a cig lighter and it almost immediatly lit up, the concentration bar went to max and it started beeping like crazy.
Well no nearer to solving the problem then, but at least you haven't been forced to call the gas board, which I think was your biggest worry.

It's just disruption as I'm going away for a few days, so I'll just turn it off at the stop-cock, and deal with it when I get back. I've tested the meter is totally static when the stop-cock is in the off position.

Back at you. I'm beginning to wonder if he's capable, either that it's just a massive windup.
He's bought all the equipment that he needs so he doesn't have to call the gas board.
He's going to sort it out later, after he gets back from a few days away.
On the upside, at least there's no concerns around the electric.
You only call the gas emergency line if you can smell gas.......
If you can't smell it then the leak is so small as to not be a problem.
As I said you are allowed a drop (it can be as large as 8mbar depending on the meter and pipework) on a tightness test of an existing installation providing there is no smell of gas, your leak is so small it may even be in the imperceptible range of drop on a manometer (0.25mbar).
If you are worried I would call a gas safe engineer as they will trace and find a leak if there is one (one as small as yours may be impossible to find). The gas emergency team will just test for tightness (badly in a lot of cases), if they find a leak they will test their part of the installation and nothing else but could leave you with no gas if they want to cap the meter off.

Oh, the meter off amazon of dubious quality and no declared safety rating. Aye, okay.
He’s going to sort it out later, after he gets back from a few days away.
Sort it how? He's not gas safe so it's illegal for him to do any repairs for very good reasons.

I'd take advice from the actual professionals that have already declared themselves over some rando that spoke to someone on a job.
Thanks, no, no smell at all and the test meter is registering zero at the meter, boiler and cooker and any exposed gas piping in the basement.
So I'm no too worried, I'll just leave the supply shut off and turn it on for a shower/cook dinner then turn it off again till I can get someone out.
Will I get a big bill if they come out and can't detect a leak?
Just tested again over 2 hours the meter has registered usage (with no demand) from 0.5845 to 0.585m3, so 0.0005m3 is 'unacounted' for.

Squirrel - was that directed at me? I was a gas safe engineer for 25 years, only recently given my registration up as I now work in the heat pump industry.
I copied those words from the NICEIC Domestic Gas Safety book so unless it has changed in the last 2 years it is still currently correct.
On the upside, at least there’s no concerns around the electric.
The electricians didn't seem at all concerned, the earth issue has been reported, but not as an emergency and I've not heard back yet ... they just said they will be in touch...they will have to come back out anyway to sign the work off properly, as they can't do that before the earth issue has been looked at and they can re-test.
Something to bear in mind is if the OP has a damaged sense of smell. He may not be able to smell anything until it's at a dangerous concentration.
Urm.. I can smell gas immediately if I misfire my cooker hob, for example.
Also the tester I bought went ballistic when I tested it with a lighter... So it's working as a fail safe.
I think some of the people reading this thread are going to need some new rosary beads by the sounds of it!
@bear I may have been confusing you with someone else but in any case, doesn't that depend on the meter?
Here's the NICEIC guidance published 4 years ago:
Acceptable leak rate for an E6 is indeed 8mbar. But that's not what the OP has, it's a G4 (handily labelled on the meter he posted a picture of on the previous page) which is half that. Have they changed the rates since then?
Regardless, nobody knows what the leak rate is since nobody has put a manometer on it. If only there was someone who he could call that could do that?
Oh and nobody is going to give you shit for doing the right thing. I was working under the floor, heard hissing and got out before calling the gas board (at 10 o'clock at night). Turns out there was no leak but it was the halogen lamp I had heating up and venting the air out the seal. Guy was happy I did the right thing.
nobody knows what the leak rate is
0.04 cubic meters per week by my calculations?
Gas meters have an asset life of 25 years. I am glad you have reported this - if the meter has a leak it would need to be replaced by the meter provider - not yourself. A leak downstream of the meter is the property owner’s responsibility.
Also the tester I bought went ballistic when I tested it with a lighter… So it’s working as a fail safe.
Different gasses pal. Natual gas is Methane, probably Butane in a lighter.
I am glad you have reported this –
He hasn't!

Yeah it's a multi gas tester... "methane, natural gas, propane, LPG, gasoline, etc."
I just tested again - this time on the gas hob just in case, and predictably it went crazy immedialty, full bars, beeping like mad and screen turned red rather than green.
Turned the hob gas off after a couple of seconds, so I was basicaly simulating a failed ignition on the hob, and the numbers of bars steadily dropped and the screen went green again over a few seconds whilst the gas dissipated in the air.
Call the gas emergency line, this is what they are there for. It is free unless you’ve done so etching stupid. They will tell you where the issue (if there is an issue).
You’d have to be bonkers to not call them FFS.
"Will I die?"
"Actually maybe, yes, here's a quick, easy and free solution, call this freephone number:"
"Meh, I'll be fine"
💥
I know, it's been said before 😁
It's still ridiculous 😉
What is the sensitivity of your tester? You're trying to find an admittedly tiny leak with it, but calibrating it by holding it near an open hob/lighter, blasting gas into the room? You said it stops beeping a few seconds after the hob turns off, but surely there's still more gas in the air at that moment than there is near your tiny leak, and it's not detecting it.
Also, there's the chance of you deciding this leak is fine, within acceptable parameters or whatever, meaning to keep an eye on it but really you'll forget all about it before long. Meanwhile the tiny hole grows and ....
Seriously, just call them, what's the worst that could happen! I think you said you're going away soon and don't want the disruption? Fine, just turn the gas off at the meter and call them as soon as you get back.
but calibrating it by holding it near an open hob/lighter,
No, I 'acid tested' near a hob and a lighter...it runs a calibration cycle for 30 seconds every time you switch it on... So I did this away from the building in the open air, in order to get as clean as possible calibration basline.
it stops beeping a few seconds after the hob turns off,
It drops from 5 bars, flashing red over the course of a few seconds after I shut the hob off, on that particular test, which is what I would expect.
There is still gas in the immediate viscinity of the tester and the hob, but then the beeps get slower, the bars drop, and the screen goes from red back to green over a few seconds as the gas is diluted in the ambient air.
There are 5 bars on the meter, going from 0.1%LEL to 0.5% LEL, the beeps & visual bars get faster as it goes up, and slower as it goes down.
So it's working as expected. In non-test conditions, I can't even get it to register anything at all, which again isn't a huge supprise, given the tiny amount of 'unacounted' usage registered on the mains meter dial.
fine, just turn the gas off at the meter and call them as soon as you get back.
That's exacly what I'm doing, it's actually off right now at the main valve, as I need no heating or hot water. I'll turn it back on for half an hour at a time to have a shower/use the cooker(testing along the way) and that's it.
Then I'll have it looked at when I have time.
This has probably been happening for years,un noticed, I only noticed when I decided to pay really detailed attention to the meter knowing that there was no demand.
"Do not use soppy water it's corrosive" something I took to heart aged 12 when I gave up washing...
Maybe just call the number. If they tell you you're fine, don't worry then it's all good. If they say we'll send someone out, that's up to them?
The electricians didn’t seem at all concerned
.... about your gas supply.
they can’t do that before the earth issue has been looked at
... in case there's, I don't know, a spark or something?
Come on Matt, two pages, literally everyone advising you the same thing. I always had you down as one of the smarter ones here. You could have had it resolved by now.
Its not often theres massive concensus on here too .
To be fair Matty hasn't smelt any gas. He's not really in a position to call the number that you phone if you smell gas.
Presumably if he phoned it they would ask him if he can smell gas, there's no point lying as they would soon find out that it wasn't true.
I don't think that "No, but I am worried because I suffer from OCD and keep checking my gas meter" is likely to be treated with the same level of urgency.
He’s not really in a position to call the number that you phone if you smell gas.
They will absolutely take it seriously. If you tell them exactly what is written here. "I can't smell gas, but my meter is going round with no appliances running. I'm worried I may have a leak."
They will come out within a couple of hours. Put a pressure drop test on and tell you straight away.
They will never moan about coming out even for little things. Just call them.
Well I guess he could claim to have no sense of smell.
Can anyone see a scenario where this doesn't end with the OP calling either the gas emergency number or a gas safe engineer? (*)
Anyone?
Anyone at all?
No? So just call them!
(* - by "end" I mean "end in a safely resolved manner with the op fully confident in the long term safety of their gas supply", not "end as the lead story on the local news bulletin")
@ernielynch stop it. Seriously. Everyone bar one has said they will deal with it, I have personal experience of not smelling gas, calling them and getting a positive response. Smelling gas is the bare minimum reason, any gas emergency (and a leak is an emergency) is worth reporting.

Equally there isn't a sticker saying "if you can't smell gas but the meter is registering usage even though you've got nothing running, don't bother us, it's probably nothing"
I normally stay out of these sorts of threads because, well, there's nothing to add.
Statement of facts.
OP has a gas leak.
Despite surchasing a detector, OP can not find the gas leak, nor where the gas is going.
There is a free service to assist with main gas leakages because gas explosions a moderately inconvenient.
...
!
Profit?
Got to say this is top level Darwinism. Pick the f***ing phone up and report you might have a gas leak.
Why is this one so difficult a concept for some folk?
Mattyfez has to be an AI chat bot set to "full wind up" mode
TBF to the OP (because everyone and their dog seems to be piling on now), he has said that he'll have it looked at when he gets back and the supply will be turned off (before the leaking side) in the meantime.
0.04m^3 a week… so 40 litres, potentially building up in a confined space in a nice stoichometric, combustion ready mixture. And with dubious electrics/earthing nearby. Nah, you’ll be reet.
You are literally bonkers if you’ve not already called the gas network people.

I don’t think that “No, but I am worried because I suffer from OCD and keep checking my gas meter” is likely to be treated with the same level of urgency.
It’s the gas emergency phone line, not the “I can definitely smell gas” phone line.
There are enough stupid people out there to make it easier to say to call if you can smell gas. Plenty of people can’t and plenty of people can but don’t care… 🤦🏻♂️
TBF to the OP (because everyone and their dog seems to be piling on now), he has said that he’ll have it looked at when he gets back and the supply will be turned off (before the leaking side) in the meantime.
But it could be the ECV that isn’t actually turning the gas off, hence nobody has any idea if it is working to stop the gas or not. It needs checked by a qualified engineer.
Oh and technically speaking, it’s a gas service up to the meter. Gas Mains are in the streets, that then feed the Services.
I know everyone has piled on the OP but if anyone knows Summerseat near Ramsbottom there was a gas explosion in a Victorian terrace there caused by a nearby fractured cast iron main that crept through the soil and was ignited in the unfortunate victims house. I walk the dog down there sometimes and it was odd looking into the shattered remains of someone's house and life.
The massive nearby pub over the river was also swept away a few years ago so the area doesn't really have much luck.

The ECV works... It's shut off right now... The meter doesn't spin.
Still not phoned then yet then?
I wonder how an insurer would react if you had to make a claim for the damage a gas leak caused and there was evidence you'd wilfully not chosen to contact someone to fix it?
