Just been on British gas web site house.co.uk and seen the offer for £300 of a boiler. It says, and I quote, "We take the best A rated condensing boilers and then make them safer and more energy efficient". If this is so does this mean the boilers they badge up as their own were unsafe or less efficient? does a man behind a desk say "great boiler Worcester Bosch but not safe enough for us and a bit more efficient please"? Any thoughts gents.
