Double glazing - Big Victorian house UPVC Sash

funkyfresh3000

Hello.

Just had several quotes from the big nationals to replace victorian timber sash windows with uPVC sash windows.

I'm not looking for the cheapest supplier, nor recommendations for suppliers, I am wanting to know what what I should be paying for a good quality job that respects the house.

I've seen other peoples quotes on line, ie. "I got X amount of windows for £X" but they never state the type or size of the windows and this severely alters the cost.

With all the BS discounts and absolute horror stories online about the "big 4" and their unfair pricing systems it is impossible to tell what I should be paying for the job. I have no idea if it is 5 or 50k?. All the companies I've recieved quotes from have been accused in forums of overcharging customers by £1000's which only becomes evident after the customer refuses the quote repeatedly.

There are 11 windows in total (3 of which comprise of a bay). They are all very large. I have included the measurements below. We want white UPVC sash, made to look like the exising windows (i.e. we don't want to square off the existing arched brickwork with upvc infills, we want arched upvc frames). I want reinforced upvc and good quality glass and security fittings.

2 x 220x125cm
2 x 220x90cm
2 x 175x90cm
5 x 175x125cm

Any ideas of what a good quality job should cost?
Thanks so much in advance!
