Do I need planning permission for a loft conversion?

Planning permission is not necessarily required. However, you will need it if you live in listed building or conservation area, if the house has been extended before, if you're converting the loft above a flat or your house is over two storeys high. In addition, if you are making significant changes and conform to the following conditions, you will need permission:

  • The additional roof space should be no more than 40 cubic metres for terraced houses and 50 cubic metres for detached and semi-detached houses
  • No extension beyond the plane of the existing roof slope of the principal elevation that fronts the road or higher than the highest part of the roof (e.g. a dormer will need permission)
  • Materials must be similar in appearance to the existing house
  • No verandas, balconies or raised platforms
  • Side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor
  • Roof extensions, apart from hip to gable ones, to be set back, as far as practicable, at least 20cm from the original eaves.

You may also be affected by The Party Wall Act 1996 if you live in a terraced or semi-detached property. This ensures your planned changes don't compromise the strength or soundproofing of the dividing wall. You will always need buildingregulations approval to convert a loft or attic into a habitable space.

Do I have to use a VELUX-branded blind on my VELUX roof window?

Not necessarily. While VELUX has the most extensive range to choose from, the RoofLITE blinds we sell are a cheaper range of blinds for most of the standard roof window sizes. They come as blackout, roller and awning. However the colour choice is limited to beige and dark blue and, for the awning blind, black only. The other advantage of a VELUX blind is they can be electrically controlled or solar-powered, so you control your blind from anywhere in the house.

Can I add an electrical blind or shutter to my INTEGRA window a while after installation?

Yes, all VELUX electrical blinds and shutters can easily be fitted at a later date on the INTEGRA® window. The original remote control will automatically register the changes and add them to the overall menu in a few seconds.

Can I install a VELUX blind myself?

Yes. VELUX blinds can be installed quite easily in a matter of a few minutes. The instructions are quite straightforward to follow. Most windows come with pre-fitted brackets to assist with the installation. However, if your window does not have these brackets, and you are ordering a new blind, the brackets will be included with the blind.

How do I identify my VELUX window for spare parts or blinds?

All VELUX roof windows produced after 1968 have a type sign stating exact information about the window located in the right corner of the top sash behind the ventilation flap. See below.
