How to upgrade to a gas smart meter if I've got a large (U16) gas supply?


Badge
Hi,
I have a gas meter for my flat that was originally installed in the 1970s for the whole house with seven open gas fires. The house was sub-divided into four flats in the 1980s but I ended up with the original house meter for my flat.
I would like to install a smart gas meter from OVO Energy but it will not be possible as it is not a drop in replacement.
How do I first down grade to a smaller sized standard meter?
I have a gas boiler and gas hob in the flat only. The 3 gas fires are now disconnected.
Do I need to contact National Grid?
Thanks

Great question @NickinHP  !

I’ve tweaked the title and added some tags as I’m sure another user, one day, will look at this topic and benefit from reading the answers below!

It sounds like your usage no longer warrants a large gas supply (U16) meter. If this is the case, we’ll be able to visit and perform a ‘downgrade’ of the meter, allowing a smart meter to go in. You’ll need to arrange a gas safe engineer to carry out a maximum load test, and if it’s below 66 kwh, a downgrade can be booked in.

This advice will probably raise more questions than it answers. I’d suggest you ring up, so that you can get transferred to our Site visit team: experts involving all things pipes and cables. They can talk you through the necessary steps. Call them on: 0330 303 5063. As I’ve got your details, I’ll note your account to advise of this.

Hope this helps,
Tim

Hi @serjio and welcome to the Forum.

Let’s tackle this question in reverse:

Firstly, you wouldn’t contact National Grid. They only handle the high and medium pressure mains that traverse the country. The next stage down is your local Gas Transporter company. If you fill out your Forum Profile page then I could tell you which one is yours. Or could work it out from this map:

 

There are a few geographical areas where there is a private transportation company who supply the gas. But for simplicity, let’s omit that issue for the moment.

Your local Gas Transporter is responsible for the gas pipes up to and including the isolation valve at the incomer side of your gas meter. So unless there are physical problems of this valve obstructing the location where a Smart Meter is to be installed, then I don’t think anything needs changing until after the valve.

 

So the next obvious question to ask is whether OVO’s Installation Engineers offer a service whereby they provide adaptors to reduce the outlet of the isolation valve to the bore required for input to a SMETS2 Gas Meter.

Although this would be at additional expense, it would at least save you having to liaise between different parties.

 

Let’s tag @Eva_OVO, who is today’s on-duty Moderator, and ask if she can draw this Topic to the attention of an appropriate Engineering Manager.

@NickinHP - wow that's a long time in advance. We don't normally offer appointments this far away. Did you book this over the phone?

Hey @madderose,

After 2020, we'll no longer continue to replace traditional meters with other traditional meter. All replacements will be for smart meters, but it'll be a gradual phase-out.

If you still need your U16 supply after 2020, a smaller smart meter won't be forced on you. An equivalent smart meter of this capacity is still in the pipeworks (pardon the pun).

Cheers

I have an electric smart meter already so just need smart electric. Please can you look to see if there is an earlier slot available in London W14 8BG area. I booked it by email and would very much to bring the date forward.
Thanks for your follow up. Been faithful OVO Energy customer for years.

Sorry just need smart gas meter.

 


You'd need to contact the customer services team about this, or drop the team on Facebook a message.

Cheers

Hey @serjio and @Transparent,

Sorry this wasn’t picked up on Thurs/Fri. I’ve had a word with the experts and they’ve advised that our engineers can add a reducer to connect between the larger and smaller pipework, so it shouldn’t be a problem at all. The only issue at the moment is that we’re operating a very limited appointment schedule due to the pandemic. We’re reviewing this as things progress, however the best course of action may be to call the team on 0330 303 5063 to discuss specifics, and check if we’re able to book this in at the time being.

Thanks!

I also have a U16 meter but in my case, I need the extra capacity so a downgrade is not an option. I am currently staying with a dumb meter as there are, as far as I know, no U16 smart meters but what happens if smart meters become compulsory? Will there be smart U16 or G10s available?

I have now got a standard
Domestic E6 meter installed by OVO Energy. I had to get a Gas Safe engineer to issue a load certificate to demonstrate the smaller meter was all that was needed. I now have booked a smart gas meter installation for November 27th. Don't know why it tales 9 months to get one.
