Double Glazing - Big Difference in Quotes from Small Companies

boxy123

My old upvc double glazing and doors are in need of replacement. I’ve had several quotes from recommended Local installers (family run companies to Sole Traders). Prices vary from £5,600 to £10,000. Profiles so far include duraflex, kommerling, rehaus or veka.
I’ve also had Veka Network quotes from companies in Warwickshire, prices vary from£7,600 - £10,900.

There is such a wide difference between the quotes. Part of me is thinking to go with the cheapest Veka Network quote as I’ve heard the network has a good reputation. However, this would still be over £2,000 more expensive than the cheapest quote which happens to be a NON Veka Network installer at £5,600.
Any advice much cheaper.

i would say £5600 is far too cheap i would say you would be looking around £6500-7

Opting for a top window profile becomes irrelevant if they are installed poorly. Go and have a look at installations completed near you by the companies who've quoted.

absolutely agree . The £5,6 quote are about a few composite doors away from a real price when you start to include the Georgian bars
