Double Glazing Quote London

[housebunny23]

Hi All,

I am looking to get white uPVC Double Glazing put in.
I have had a quote of 4100 pounds including vat and fitting for: two front bays, Box room window and rear bedroom window (so four windows in total).
The reviews on trust-pilot were excellent and they use their own fitters.
Is this a good price and has anyone paid less or more than this? (This is the cheapest so far from all of the others ).
The spec is: Seal uPVC Profile, Guardian A rated Glass, Espag handles and locks ( not sure what any of that means )
Any advice or recommendation of a good Double Glazing Window supplier and installer in West London?
( have been told a German uPVC Profile and Planitherm Glass are very good, but not sure if I could afford it ).

Sounds like a lot for 4 standard type windows. I paid less per window for a whole house of UPVC sash windows earlier this year.

It pays to shop around. Get 3 or 4 quotes. We went with a look local firm with a good reputation that fits a very high quality product (Bygone Colllection from Masterframe). It was much cheaper than both national and regional brand names offering much lower quality products.

Sounds about 1000 too much to me
