Urgent help pls - moving gas meter

[Dubonet]

Looking for some urgent help! Can @pigletjohn help?

The gas meter is being moved from a pretty inaccessible location inside the property to outside the property. SGN have said that there will.be a cost as it's moving more than 2m, fair enough.

They plan to dig up part of the garden and bring the service pipe and meter to the back of the property. The wall where the meter will be relocated to is the same wall that the boiler flue comes out of.

As we are installing a new boiler the boiler installer said they would reconnect the service pipe to the boiler - I think this is correct?

My question is about the other gas appliances in the house. There are 3 gas fires and 1 cooker. Will these be impacted by this move in any way? I asked the SGN engineer and he didn't really respond, saying the boiler man will reconnect the boiler, but it has just occurred to me that the other appliances will also require new pipes to them?

The added complication is that the gas appliances are in several different rooms and that the kitchen appears to have a concrete floor.

The boiler is not in the kitchen currently and we cannot move it to the kitchen so it's remaining where it is in the dining room.

Will there be any impact on the current gas appliances I am sure there will be but SGN has not responded to my email and I can't get the engineer on the phone.

Thanks in advance!

SGN will move the supply pipe and the meter. Reconnecting the internal gas pipes will be up to your gasman. The electrical earth by the meter must be bonded to the metallic pipe shortly after it enters your house. The gas installer should know how to do this but sometimes you may need an electrician

Quite possibly it will be linked up to your existing pipework in some way by taking up a floor. This will be difficult if your floors are concrete. Try to avoid running pipes on the outside of the house. This is cheaper but a bit unsightly, and they are more prone to damage and to theft of the scrap metal.

Remember that the new boiler might need a larger pipe. If it is in the kitchen it can be laid big enough to tee off for a gas cooker. The price of a bigger pipe is not great unless it is done afterwards.

@pigletjohn thank you so much for your advice.

My boiler installer has advised that he can connect the new meter to the old meter or the pipework at the old meter using 12mm pipe. Does this sound like it would work? If so, its good news as we won't need to run pipework through the house and we can just use the existing connections to the appliances. The only floor that is concrete is the kitchen, as it was an extension. The boiler is not in the kitchen, presumably because of this concrete floor.

I haven't heard anyone mention anything about bonding the electrical earth to the gas meter. I'm not even sure what this means but I will.be sure to mention it to the installer.

Thanks again, you are always so helpful

12mm sounds unlikely.

Did he mean 22mm copper pipe?

Connecting to the pipework at the old meter is probably OK, but you don't want pipe running (say) twenty feet northwards to join up to old pipe that then runs twenty feet southwards, doubling back on itself.

Pipes in kitchen can often be run on the surface of walls, where the kitchen units will hide them.

22mm is correct, I just double checked the email from the installer. I agree with the point about pipe doubling back on itself, I will see if they will check this to see how the pipes run bearing in mind that they are just tacking this on to their central heating job

Thanks @pigletjohn! There's a reason you are a mumsnet legend!
