They are simple to fit if you follow the instructions - my husband managed to replace ours so they must be fairly idiot proof. We bought ours on line I think from Velux themselves....definitely not necessary to pay someone to do it for you.

Good luck!

Matt who runs Skylight Services is brilliant - he serviced and replaced a few Velux blinds for me last year - one replacement came with a tiny pinprick hole (manufacturer's fault), which he pointed out to me, he then sorted this out with Velux, called me when he had the new replacement and came over to fit it.

Peter jones on slane sq or any john lewis.. Very easy to fit yourself, waste of money to ask somebody to do it. ;)

Does anyone know of someone who can supply and fit one of these?
