Woek up this morning and the window in the bathroom has jammed.

It looks something like this but going upwards.

If I pull the handle the lock opens up and if I push outwards then the top
half of the window starts to open but the bottom half is totally stuck.

I have tried bashing it with a hammer and sticking a screwdriver in to pry
it apart but no luck.

I am thinking that maybe the actual runner type things inside have
broken -
hard to explain but when you pull the handle there are 2 sets of locks
(top
and bottom) that slide upwards that allow to window to open.

Problem is I see no easy way to fix this without totally having the window
pulled apart!!

Taking the double-glazed sealed unit out of its frame might let you see
which part has jammed or broken, and even let you spray with WD-40 and free
it up.

Pretty unlikely I'd have thought; don't think I've ever seen a way of
accessing the locking mechanism from underneath where the sealed unit goes.

Otherwise you need to contact the original installer or look in
Yellow Pages, double glazing repairs/repairers, request estimates, then
request repair callout. If the opening window can't be repaired or replaced
you could be looking at having the whole frame replaced although it should
be possible to re-use the sealed units. Good luck.

Certainly a tricky problem by the sounds of it. I think your best bet
is to contact a specialist uPVC window repairer - they do exist -
hopefully a good one with recommendation. There may well be some trick
or other to solve this without causing serious damage; uPVC windows and
doors are like that.

Might also be worth trying:
