Anyone around for a quick ball-park price for replacement windows?

[Bewooohooove]

Got a salesman coming at 6. Bog-standard white UPV double glazing for 3 large windows. Any ideas what to expect?
I'm hoping less than £2000, is that unrealistic?

We have 2 large windows the traditional ones with 4 panes of glass and 4 smaller square like windows with 2 end ones opening(if that makes sense)
But 1 smaller one 1opening top and 1 large side opening.

There mahogany on outside and white inside with leading
We paid £2200

Yours sound much nicer than what I need, and I'm hoping they can re-use my mahogany sills so maybe I'll get the 3 around that price (here's hoping - I can't abide hard sellers so I'm fingers crossed this guy will be nice)

Well, as I suspected I spent more than I intended
Ended up going for the triple glazed units with mahogany sills.
