Advise on Replacement Double Glazing

Just moved into a 1920s semi which has the original wooden sash windows which look lovely but are requiring attention i.e new putty, replacing some of the glass & completely repainted. I have seen a few glazing specialists with a view to either making good the current windows or going for double glazing. One FENSA company has suggested the following:-

Replace windows with standard outward opening casement windows. Fitted into existing timber box frames and trimmed with upvc

I spoke to the installer and he says that from the inside the windows would have the existing wooden frames but with double glazing whilst on the exterior the widows ledges wood be UPVC as descibed above. He says that this is quite popular as it is cheaper than removing box sashes and architraves and going completely MDF.

Has anyone got an opinions on this? I am on a budget so I am tempted but another company I spoke to were quite negative about this hybrid solution

If you possibly can, get the existing windows restored. You can't beat the apearance of existing timber sashes. UPVC will do nothing to enhance the propertys' character.
Replacing some putty, glass and repainting is not really major work, especially if you do the work yourself. I have got single glazed timber windows in my cottage which I have kept with a bit of filler and putty. It's just a question of putting a bit of time into them.
