Triple-glazed aluminium-framed sash windows

[strret00]

I was wondering whether anyone knew how much it costs to replace 9 sash windows (roughly - I'm looking for a ballpark figure).
The windows are approximately 1m (width) x 1.5m (height).

I would like the new windows to be aluminium-framed and triple-glazed.
(Two windows need to be sand-blasted as well, as they are in the bathrooms.)

I live in Central/South London (SE17).

Does anyone know any companies that specialise in windows like that?

No one will be able to price a window with a spec like that on here. You are going to be looking at a fair bit. When you say sandblasted I take it you mean just the glass. Why do you want Ali? I could price it but not until I get back to work on monday
