This is not neccessarily true.

Thanks for the unput, So you are saying it's not *necessarily* true,
but just possibly true, yes?

Possibly, but you are entirely in Transcos hands here. It all depends on the
pipe size rising up the building and the unseen length underground. If its
an old pipe they may want to run in a new supply back from ther street main.
They may just decide to run in a bigger "shared supply" and renew the supply
to the rest of the house but its their call and though you might get a
sympathetic surveyor you just as easily won't


As you are now talking about seperate
households each will be given a supply capable ("properly" not under
overload conditions) of delivering 6m^3 per hour with only the
permissible
pressure drop i.e. not below incoming supply permissible limits. A pipe
which used to give 6m^3 may not be able to give 12m^3 under these
constraints.
You should ask for a quote to have a supply of gas installed and go from
there.
Transco operate to engineering standards which are not negotiable.

Wish I knew the best way to maximise my chances of avoiding having to
pay for an entirely new 2nd gas supply... I bet tsomeone out there who
knows the answer.

Instead of asking until "someone" gives you the answer they think you want
to hear you should start the estimating route and fins out what the
Engineering answer is. It doesn't matter what group readers say it isn't
their call.
