I don't live in your area. Is this supply only for diy fitting, or supply
and installation? If you want to fit them yourself and are confident about
measuring, and familiar with the regulations including which windows if any
need to be toughened glass and fire openers, any local double glazing firm
can make up the units to your measurements and specs. You can get some idea
of supply-only prices from here: http://www.u-fit.co.uk/windows/default.asp .
If you want supply and installation then recommendations from friends and
neighbours would be useful.
