Are there any regulations regarding where the incoming gas pipe (e.g. on the supply side of the meter) has to be relative to the wall?
I'm trying to work out how much aggravation there will be in getting the house insulated (not all the walls are cavity walls), and from what I've seen of other properties nearby that have had foam added to the outside, this would place the gas pipe well within the foam (which appears to be ~4" thick).
As well as the gas, there would also be problems with drain pipes, vent outlets, window cills, and probably loft ventilation.
Thanks
