What is a rooflight or Velux loft conversion?

A rooflight or Velux loft conversion uses the space that is already underneath your rafters, so no roof extensions or dormers are required. Velux windows or rooflights are fitted into the ceiling, meaning that these types of loft conversion are naturally light and bright.

There are two main types of roof window we can install: centre pivot and top hung. A centre pivot window spins in the frame to allow for ventilation, whereas a top hung window hinges open from the top of the frame. We can discuss all options with you at your free design appointment.

Transforming your home with a rooflight or Velux loft conversion

A rooflight or Velux loft conversion is the ideal economical way to make use of the space you already have. Here are some of the main points you’ll want to consider.

Will I need planning permission
for a rooflight or Velux loft conversion?

As there are no roof extensions, you shouldn’t need planning permission for a rooflight or Velux loft conversion. We will be happy to talk you through the process, telling you more about planning permission and your permitted development rights.

Rooflight or Velux loft head height

One of the key things to bear in mind is that you’ll need enough head height for this type of loft conversion – around 2.3m minimum. If you don’t have this much height available, another type of loft conversion may suit you more, such as a dormer, hip to gable or mansard.

However, if you have plenty of space – around 2.5-2.6m of head height – then you don’t really need any kind of roof extension. There will be plenty of room to walk around already, so we can directly convert this space into living space.

Building regulations for rooflight or Velux loft conversions

Your completed Velux loft conversion will need to be approved for building regulations. During the inspection, the following points will be covered:

  • Structural stability
