depends how far it is from the meter. the information you have given is insufficient. Additionally, any engineer giving you a quote will be able to calculate this for you.

and the combi is

I can't remember the name its a friends boiler however it s not a name I have heard of before. The combi that is in at the moment isnt a condensing boiler

working fine doesn't mean working correctly. New boilers are more likely to experience problems with undersized gas supplies than old ones. Many gas supplies are undersized. It may be ok, but only if its relatively short, and the combi one of the smallest. <24kw.

Don`t know of one single combi that don`t require 22mm feed. That is all.

It`s probably a conventional boiler.

its prob right above the meter or it ain't working right

Probably not a combi taking into consideration any other gas appliances. It may be fed in 22mm then reduced to 15mm at a point where the poster can`t see. Only way to check is by working pressure at meter then at boiler.
