I have just had a new Worcester-Bosch 24i system boiler installed in
the loft to replace a 30-year-old non-condensing boiler in the
kitchen. Tests show it is "undergassed". The installer says it may
be a problem with the gas meter governor, in which case they say
Transco would have to fix it. However the 22mm pipe required by the
boiler is connected to a 15mm pipe from the gas meter. Should the
installer fit a larger pipe to the gas meter instead of blaming the
governor and shifting the problem to Transco? Any advice most
welcome.

As a GasSafe engineer. I would not leave any appliance attached to any gas pipe if the input pressure did not meet that specified in the Manufacturers Installation Instructions. If there was a problem with the meter governor, I would ask the O/P to attend.

I imagine Mr Mendoza has either had it fixed or blown himself to
smithereens in the intervening ten years...

While you are correct, it is welcome to have someone this group who is
both versed in gas and helpful. Elsewhere these two characteristics seem
mutually exclusive.
