My daughter has an old victorian house with sash windows. She has

my feeling is that it's not too bad).

The prices are for supplying and fitting 'vertical slider,
counterbalanced 4mm toughened glass' secondary units.

For two about 1.3m x 2m they are about £500 each
For two about 0.5m x 2m ther are about £380 each

Prices ex VAT, total for four windows, installed is £2140.


Seem reasonable?


From the v few I've seen over the years seems the right ballpark for
London at least.

Off your topic but I'll offer that worth checking she (or her staff!)
will be able to clean the windows - i.e. /full/ sliding and a big enough
gap to reach in and clean; or tilt as well as slide; or easily removable
- in practice not just in theory, bearing in mind weight.
