We are considering getting our (N. London) flat's windows double
glazed, here's a picture of the flat from the outside, all our windows
are on this side.

Our flat is the lower one of the two duplex flats in the middle of the
block, i.e. its windows are the bottom four windows under the upper
duplex flat's balcony.

So what sort of ball-park figure are we looking at to get all four
windows replaced with double glazing? All the windows are are floor
to ceiling and the downstairs one on the right has a door onto the
balcony.

A few thousand pounds I guess, tens of thousands?

Also, any recommendations for companies to do the work?
