No less than 18 mb inlet point

In worse case situation when you come across a service and the pipe size is too small. What do you do notifiy the client that it's required upgrading or contact gas supplier to tweet the incoming supply.

cant tweek incoming as its acceptable

depends if it effects gas rate if not juts advise if it does follow the rulings

Problem with things like this when boiler has been in place for some time and as far as customer is concerned the boiler is working OK is trying to convince them that they need gas supply upgrading most will look at cost & disruption involved, you know they wont get it done, if you push them it will be the last time you do any work for them and will take there custom elsewhere, Unless its ID not a lot you can do.

Pipe Size sounds OK.
As above, check for a blockage in the Gas Valve filter/or pipe work.
If the filter has Copper Sulphide in it, you may need to clear the pipework too. As that stuff builds up it can heavily restrict the Flow of Gas.
A lot of modern Boilers have a 'bigger than you'd expect' drop from the pipe connection to the Gas valve test point.
To be honest, if its Gas rate is good, pipework and filter is clear and it doesn't effect any other appliances I wouldn't worry about it.

Thank you very much guys you'd have push my ability on to another level. I didn't pass my gas through the help of my employer you guys did it especially thank you too Shaun I wouldn't be where I am because of you. If I could buy you all a pint every time I've needed help I'd be a poor man especially when I'm only getting £8.50 per hour. Thanks I hopefully will continue to pester you guys from time to time with stupid questions.

Are you the only gas safe person in the company?

 

[Inverness]

There's one other guy and he said it's ok too but I prefer asking your advise. 3 weeks today I'm going out on my own!

Correct me if i am wrong chaps but is this not AR? The boiler clearly has undersized pipework? Worcester allow 2.5 mbar from meter to inlet on gasvalve.

Aslong as it doesn't adjust the figures out of spec they say it's fine down to 14.5 mbar

Unless you can find anything to the contrary, undersized pipework is only the old NCS. Unless it is proved to be affecting the safety of any appliance, in which case it is ID. So either poor combustion resulting in CO to a room, or burner outage on, say, a cooker ring, when the boiler kicks in
