Been having a new gas central heating installed over the past few days. The original system was installed by a complete Cowboy, and has been a right pain in the ... so as I'm now partially disabled and getting to the age where I need my comforts etc. I went to British Gas for new system; BIG MISTAKE! I don't believe I was stupid enough to actually believed their promises! BG sub'd it out to local installation firm who turned out to be.... well, to give you an idea, whenever one of them picked-up the circular saw, he went "Yee Haa", every ***kin time; I don't think I have ever heard anyone go "Yee Haa" and genuinely mean it! I had to ask then to fill in the holes they left in the brick-work (they still haven't done all or them), the house is a right mess ("We leave your home as you would!"!). The gas pipe has been run outside, even thought I asked them not to. In spite of repeated promises, the electrician still hasn't been to fit the lecky supply to the boiler, and the earth bond to gas pipe. So I still don't have any heating or hot water.
It may well be a good system, and I'd like the opportunity to find-out!
My advice, keep clear of BG, they are heavy with the promises "We charge more because we fit the best", "We leave your home as you would", but light on delivery!
