Dear Majove...I've just bought my dad a new gas cooker and with all the new rules and regulations you (literally) cannot do anything yourself anymore... for one thing the oven doesn't come with a hose at the back and you can't buy one so you have to get a gas fitter to bring it... also they now have to be chained (literally) to the wall -more expense ... it worked out to over �100 more getting these things done before my dad could use it.. most of the gas/electricity oven supplies have a list of extra charges now..for -. delivery...taking old one away... fitting... etc etc...Someone in the Govt must lie awake at night thinking up all these new rules and regulations...
