Getting a gas smart meter installed- Is access needed to the electric meter/cellular hub?

A relative has had a smart electricity meter installed at their property. They’re now looking to get the gas one changed too. They’re wondering if access to the electricity meter (likely the cellular hub) is needed when a smart gas meter is installed?

The electricity meter is inside, under the stairs, while the gas meter is about 3m away, mounted on an external wall outside. 

As the electricity meter is under the stairs, and they use that space for storage (nothing flammable or likely to catch fire if anything were to happen!), it is an absolute faff to empty that area.

If access is needed to scan the barcodes on the cellular hub, such as the CHF or GPF ID, will a picture of the meter suffice? There is a little viewing window in the wooden panelling so the meter can be seen and numbers verified, but impossible the barcode be read by a scanner at that distance. 
 

They’re not with OVO (I am, however) so thought I’d ask here. Their gas is with British Gas, and electric is with EDF (they’re not interested in switching - no matter how much convincing I’ve tried)

Hey @strategic_goose,

 

Unfortunately it’s not a clear cut answer, but here’s advice from one of the experts:

 

It depends. So the dependency is on the signal to the gas meter from the location of the electricity meter where the Communication Hub is situated.

 

The fact you have different suppliers adds complexity but doesn't affect it all being possible. It also depends on the process the installer follows.. they WILL need the details of the ​​​Comms Hub Function in the Gas meter (it's a code on the Communication Hub needed to join to the Gas meter) to set up the Gas meter and get it joined but may not need to scan those locally.. some do, some don't... the key deciding factor is if the gas cannot connect and a Dual Band Communication Hub is needed.

 

That will require a process known as ‘Trust Centre Swap Out’ to replace the single band Communication Hub and replace it... so the Gas meter can connect and work... to 'punch' a signal through the wall... having both fuels with the same supplier is easier but not explicitly required as it's designed to work with separate suppliers.

Does this mean he didn’t exchange the gas meter?

He didn’t exchange the gas meter. He checked both, connected new IHD (I didn’t have it) and explained about the gas meter. But it was over a year ago. (As he didn’t need to change my electricity meter, I assume it was already SMETS2)

Not sure what you mean by ‘asking for a meter exchange’? I don’t particularly want to move over to any smart meters until I’m forced to.
  

If you ask for a replacement meter, it will be a smart one. There aren’t any others. Why don’t you want one if it solves your problem?

OK. Time to book a gas meter exchange, then. When you do, explain the situation so the engineer will have an idea what kit to bring with him when he comes. Be prepared for both meters to be exchanged - it’s often easier to get the system working if they start from a clean slate.

Hi

It’s not urgent. I was hoping to be just get a gas smart meter but apparently that isn’t possible. It’s only an issue in the winter - I’ll reconsider come the Autumn.

Will I be able to have a gas meter installed if I change supplier to OVO from SO energy?  SO energy are not installing gas meters at the moment. I maybe on the waiting list for 6 months or more and I need to get my investment property back on to a gas supply.

Hi ​@Sylvie ,

AFAIK the answer to that is yes. You’ll need to switch over the Electric first if there’s currently no Gas supply, which you can do via https://switch.ovoenergy.com and once that’s set up, you can put a request in via OVO Support to enable a Gas supply and have a meter installed.

If there’s a registered gas supply already, you may be able to switch both at once but if not do Electric first and go from there.

Hey ​@Sylvie,

 

Has all the pipework and additional work been completed, or is the property currently set up for gas before arranging for a meter installation? Additionally, it's important to know the gas pressure for the property. Will you be living in the property, or will you be renting it out? 

 

I've included a link below with more information on our engineers' prices. When you call to arrange this, they will confirm everything with you.
