Replacement window quote - reasonable?

[GSXRMovistar]

Looking to replace several windows in the house (and a side door) to match new ones recently gone into a new extension.

Quick/poor sketch up of what is being quoted for:-



bottom left is not part of the quote (my builder is paying for that one), F are frosted/obscured for the bathrooms.

Style of window:-



For supply/fit/making good/taking away old I've been quoted £4110 all in, is this reasonable?

Many thanks.

If there are like the picture (fully Sashed) that is a reasonable quote.
Quite rare to see this but it does look so much better.

Yes each panel (both those that open or not) do have a full surround/sash.

Now I'm even more confused, some saying the quote is reasonable and others saying its way over.

I think the fitting costs for windows and door come to approx. £800.
