You cannot buy spare parts on the Velux site as it just doesnt work. You have to buy via 3rd party drop boxes which are poor quality and not very informative. Delivery times are ridiculous, if Amazon took this long they would be out of business! The 'colour by me' chart is really poor as the sliders do not show much variation within the chosen spectrum. It would be much better to show say 5 yellows, could be named like 'Sunshine yellow' etc. or RAL colours or Pantone colours. The company has appalling references on Trust Pilot, if I was the CEO I would shake the whole place up!
