I would give zero points if l could. I have been waiting now for nearly two years yes that’s right two years to get a pane of glass in my conservatory roof replaced. The roof is tinted BLUE they installed a replacement BROWN pane not once but TWICE. They should have come this week after waiting another four months but they cancelled as the depot had returned the new pane unit to the manufacturer as it had been sitting in their depot for three months! The incompetence of this company astonishes me. I have a 10 year guarantee on the conservatory and have wasted nearly two years getting one thing dealt with. They should extend my warranty to compensate for their incompetence. Will never use them again and would not recommend anybody to use them. They take your money and then you are on your own!
