We just got most of the windows in our new house replaced. Or, to be precise, they're finishing off fitting them today. We went with a local firm, and we've got really good, A rated windows now. Price was £3900 for 2 large, semi-circular bays (5 windows in each) and 4 windows (one of which is very big). The French doors in the kitchen didn't need replacing, and we're leaving the huge sliding doors in the back reception room til later. We're going to replace the hideous front door later too, as there are more urgent things to do first.
