I'm having a Velux window installed as part of some roofing work soon
and the roofer has asked me to buy it.

The Velux catalogue is pretty straightforward, but they don't sell
direct. So..

1) Does anyone know if there's an approved dealer network. I'd rather
not just pick an advert out of Google. Alternatively has anyone bought
one from a supplier they'd recommend. The Velux website amazingly
doesn't have a phone number.

2) The window is going in to a single storey bathroom. The roof is
slate and the property is old (1700-1800) but not listed or in a
conservation area. Do I need permission to fit it? (and I am putting
in obscured glass, before you point out the problems of being
overlooked).

3) I was thinking of pushing the boat out and getting an electric one
with rain sensitive whatsits etc.. anyone got one of these.

4) Is Velux the best brand - anything else I should be considering?

thanks

Simon
