Had a complete new system installed. Great salesman with great promises. Was told it would take two engineers four days to complete. Install day came one engineer arrived I asked where the other one. I don’t like working with anyone else he said. So he started. 7 days later still going. Floors butchered brand new kitchen cupboard basically hatched light fitting smashed. Can safely say this was turning into a disaster. On fill up day my god I have never seen Dutch a sh*t show water flooding out of the hall ceiling and one of the bedrooms at this stage I had been in touch with the regional British Gas manager complaining. I am now nearly four months on and still having issues. Water hammer issues. Finishing imperfections. In my honest opinion I would not use British Gas if my depended on it
