I've just looked at my hob fixings and found it is connected to the supply via a flexible hose. Is the use of fixed piping a newish regulation. The kitchin was here when we moved in 4 years ago although its probably a few years older than that. I believe the kitchen was fitted by Magnet.
Why would it be required to fix a hob with fixed pipework whereas a cooker can be fixed with a flexible pipe?
