Answers:    Yes, in the UK. I quote "All flexible gas hose must conform to (be tarnished with) BS3212, and not exceed 1m in length.
Flexible hoses must be installed short stress or tight radius turns."

It's usually used behind the appliance, to connect between the solid gas pipe and the fire, cooker, anything. Necessary because different appliances have their inlets surrounded by different places.
