The Velux website hat I have used for spares in the past began the process of selecting a replacement blind but then went into a loop. I finally rang the helpline number and was told there is a separate site for blinds. Velux kept this secret! The Velux agent stayed on the line with me as I changed site and went through the ordering process which was fortunate because I was asked to choose the model of blind from a long meaningless list. Improvemnt in this process is required to reach Velux's usual standards.
