Hi guys, was supposed to be a on a job today, fitting a new radiator to a kitchen, and piping up 2 newly added radiators. Turned up today and the customer has asked me to quote for additional work. The gas meter is being moved from the garage (which is currently being converted to a kids play room) to the front of the property (external) It's only about 8 meters worth of pipe, drilling through to the gas meter and connecting up. He wants it all done in one go and I don't want to be back and forth so said I will return Wednesday and do it all together.

Approximately what would you charge for something like this? Gas pipe will be clipped to the floor, run round to where the meter is, sleeved through the wall and connected up. Nothing big needs to be done.

Thanks.

Edit: it's not me moving the meter, just making the connection to what's already there.

Phil's right, instead of throwing pipe sizes at Ash it'd be more beneficial to him to help him with the working out for future jobs. I know most of you can get it right by rule of thumb and experience but our boy's not quite there yet.

I’ve done all of the math just now on paper. There are could be more bends and elbows though.

Ok so lets say for arguments sake it does definitely need 28mm.

That would be 28mm from the meter and only reduce it at the points it branches off for each appliance?

I'd say 99% of houses I go to it's 22mm off the meter all the way to the boiler and 15mm for cooker/hob. I rarely see 28mm from the meter!. I should get back to this property tomorrow and will check the appliances. As it's all in 22mm now does that mean it's all been incorrectly sized up to now or does moving the meter 4 meters away and adding in a few 90's make that much more difference?

I'm happy to do it the correct way but it's frustrating thinking how little I see 28mm on peoples houses if this is the case. Thanks for all the replies.

Ash. If its 4m longer and you have 2 branches/legs.
That 4m can then effectively becomes at least 8m or with an elbow etc more...
It Can make all the difference...

...especially when its being audited by gas safe.

I cant see diagram as on tapatalk and its not showing

Ok ill check KW of the appliances when i next go back. If 28mm is required that's what i will advise. I know the customer is not going to want me to upgrade the whole lot to 28mm but if that does turn out to be the case he will have to go elsewhere. I might be lacking experience but that's why i come on here and ask questions. I know some guys who would have just extended the 22mm no questions asked.

if they are all working ok now if you put 28 from meter to existing youlll be fine it loks like your loosing 1.5 of 22 up to existing meter so only adding 6.5 stick it in in 28 if the appliances are low add a bit more but i doubt there would be a problem

My personal opinion would be to run the new pipe in 28mm under the floor even if it didn't need it. My reason would be that there boiler in at the moment is probably ok off it now but if in the future they want it ripping out and a nice big combi installing then chances are they will have to upgrade the gas to cope, so as someone has already said it's just future proofing it and it will be cheaper and easier to do it now than having to rip up floor boards etc in the future. I would explain to them why you want to do it like that and most people would probably go for it.

As for your question about why you hardly ever seen 28mm is that a lot of new boilers installed the gas pipe is undersized, people just put them in and not think of the gas pipe they just see 22mm pipe and a 22mm connection and connect it up. If you size the pipes then you will see that if you have a combi and a cooker and a decent run 9/10 it will need some 28mm.
