Commercial or domestic gas supply

[jaydebruyne]

hey,

So am due to do some work at a domestic property above a restaurant. The domestic property has been run from the commercial gas supply.

This isn’t right, surely? The domestic property has been fitted with an AECV. I need to upgrade pipe size to water heater.

Gas safe reckon they need their own meter but I just wanted to double check as the gas safe guy sounded like he couldn’t really care less about talking to me.

Aslong as it's a u16 or under yes they can

"A maximum installation volume supplying an individual dwelling or non domestic premises of 0.035 m3"

I posted that ?

Not when gas safe are involved a domestic engineer can work on / change a commercial supply aslong as it's under 35mm and valved so it's under 0.035 what there working on

You posted that!


It's simple to me and it goes like this:-

1 Is the 'Primary' meter U16 or smaller?
2 Is the installation pipework 35mm or less?
3 Is the Maximum installation Volume including the primary Meter less than 35 dm (0.035M)?

A 'yes' to those three will confirm that a domestic engineer can work on it and therefore whether it is a Commercial or Domestic sized Gas installation (pretty much and even though I think it barmy but that is another subject).

So in answer to your comment Shaun First off we need to decide whether the installation is classed as Domestic or Commercial.

If it is classed as Commercial, then a domestic engineer cannot work on it. Even if they section a part off that is smaller than 0.035m. This is because the installation is commercial and at no point does it change into a domestic.

I’mmmmmmm soooooo confuseeeedd

Don't be confused Harvest. It's straight forward.
It is either a domestic size gas installation or a commercial size installation. That to me dictates who can work on it. There are no Half domestic half Commercial installations in my book. Never seen one anyway.

I’m confused now. I haven’t seen the meter yet as I never went to the restaurant because it’s commercial and I don’t have a ticket.

I would think that if I need to shut off the ECV at the primary meter (in restaurant) to work on the section serving the domestic flat, I’d need a commercial ticket? I’m pretty sure the pipework is 35mm steel and then then tees off in 22mm copper to serve the domestic property.

Not sure what to do ???

I would do my work and get paid

It would be something different if you had to tap into the main run / supply

I must admit, it does nark me that the goal posts changed to allow this

Lol
It's up to you.
I personally would look at the Restaurant installation and decide if it's within your remit and if it is, there's nowt to think about, get on with it.

Order a Meter from BES.

If it's definitely Commercial, you are then working an a section of a Commercial installation. It is a small section, granted but never the less, it's Commercial.
In my opinion.

Ask Gas Safe their thoughts. If they categorise it as within domestic remit, ask them to put it in writing and send it to you. That way you have a come back should you get pulled for anything.
