I am going to fit a kitchen in my house, & will be having a gas hob cooker fitted to the worktop. The gas pipe needs to be run at the back of the cabinets, i can solder copper pipe, & will be using a gas fitter to connect to the old gas pipe to the new pipework, is it legal for me to do this, & if i start to fit kitchens for a living can you have a gas safe qualification just for carcasing pipework only. I have a plumbing qualification after going on a React course after being made redundant which is domestic installation & domestic maintenance, cheers if you can help.
