uPVC windows: handle/lock is broken

Anyone got tips on replacing/repairing uPVC window handles?
The problem is with a small casement window. The handle is stuck in the open position, due North and won't turn into the closed position, due West.
The handle has a pushbutton/keyhole combination on it. Is it easy to "swap out" such a dodgy handle?

Flick through yellow pages for a local uPVC supplier, you'll find they're all pretty much the same and cost about a fiver. Maybe take the old one to compare screw centres but they'll be the same almost guaranteed.

Depends on age. Obsolescence may mean having to replace the whole window.

Absolutely false.
With the handle in the "open" position it is simple to remove by releasing two screws.
Whether the locking system is Cockspur or Espagnolette the OP will be able to replace, the fittings are almost universal. A local fabricator can probably supply from stock.

All the recent ones I've seen were compatible. They seem to be held on with just one screw under white cap .. easy to swap out. 2 local installers here gave me several samples for nothing. However, it could be your problem is the actual window lock mechanism, much more difficult to fix.. Remove handle, if mech won't turn even with wrench on square spigot, get local supplier to investigate.
