Unlike cheaper uPVC frames, sash windows offer an authentic look for older homes and these days they can still be manufactured to reduce your energy bills. Older sash windows often consist of only a single pane of glass causing draughts and resulting in higher energy bills. Fortunately, however, you can save money and keep warm with new double-glazed sash windows. Made with frames styled to suit old Georgian and Victorian designs, they still offer all the insulation and energy-efficient qualities of cheaper uPVC window models.

New double-glazed sash windows will vary in price according to the size of your windows, how many you need installed, what type of material you opt for and the final style you choose, but the following table lists some average costs for three of the more popular kinds of double glazed sash window:

Measurements (mm) u-PVC White (£) u-PVC Cream/Natural (£) Oak Timber (£)
600 x 1000

£167

£192

£209

1100 x 2950

£419

£482

£524

 

Although the prices listed above only include the smallest and largest double-glazed sash window options available, the cost estimates should help you to work out a rough guess of any measurements in-between. It is important to remember, however, that this is just a table of average quotes, and for a more accurate guide to pricing you should get in touch with a professional window installer, who will be able to carefully calculate costs according to your chosen design and size of your new sash window.

Hello all,

My girlfriend and I have moved into a 100 year old victorian house and there is some single pane sash bay windows in the living room that are typically drafty/cold…

We are keen to keep the period features in the house and would like to consider our options to update the glass to double glazed.

Please can someone be in touch to quote for the works?

Thanks
