My scoring is lower than it could have been as, somehow, my Velux window has the wrong sash in it. Ordered the correct blind, for the label on the window, but my sash has no electrical connection behind the grey plastic top plugs. Removed and broke the grey plugs, phoned Velux as all seemed wrong. Great service over phone, but another 2/3 weeks wait for a now solar blind. Window has correct label, very odd. It’s been installed for probably 12 years. From memory I bought it from a Travis Perkins outlet, which may have been why it was at Travis Perkins in the first place? Odd though, as I’d previously made the window itself operate electrically.. I then realised I’d need new grey plugs to replace the broken ones, that wouldn’t fit the new blind. So phoned angain to order them. All a bit of a palarva. A month on, still haven’t got the blind I need.. just constructive feedback. When they work, Velux products are amazing
