price for this job in donegal done by a registersd gas installer is €170 for range cooker type. this includes drilling external wall, putting conduit thru cavity, putting plastic coated copper pipe thru conduit and run from gas bottle to rangemaster, safety chain and shut off valve behind appliance, regulator for gas bottle also inc. in price. basically all you have to do is supply the bottle. i'm sure for someone on mains gas that already have gas in the kitchen it should be cheaper.they also provide cert. stating work was done by a registered gas installer. i think more lenders insist on this now
