around £30/40 a time . also fusion welding i specialist job and not just anyone can do it i would imagine only a very small amount of corgi guys would be qualified to do it. Also mdfe should only be used externally,
The only time it should be used on internals is when running between buildings of a large property and then it should have a suitable transition fitting to take it to copper or steel best practise being a metre away from where it enters the property
Sounds like you will probably need a U16 meter on this if all appliances are going to possibly be run together.
The 837 will use 4m3/hr so that only leaves 2 at the most, so assume the fire will use around 0.75m3/hr that only leaves 1.25 m3/hr for the very large range cooker you say you have.
Chances are your G4 or U6 meter will not be giving the full 6m3/hr anyway.
