Bathroom window

KTJ_2

Im getting some contractors to sort my bathroom out. Tile it, install new suite, etc.

The bathroom will need a new upvc window. My question is 1) Is there anywhere you can buy said windows from and 2) will my contractors be able to fit it..

Or...will I have to go through a double glazing company?

B&Q sell individual windows but only in specific sizes and one style.. I found it cheaper to buy one from them but was lucky in that the window size was close to my old window size.

Fitting isn't difficult but obviously it depends on how much adjustment can be done/needs to be made to get the window to fit.
