What to include in your roof window installation budget

The price of doing a roof window installation depends on several factors. When you budget for your daylight upgrade, there are a few things you should take into consideration:

  • The type of roof window and frame you prefer, and your choice of glazing
  • The size of the roof window, as well as how many windows you want to install
  • Which type of roof you have, and roof accessibility - is scaffolding or other equipment needed to reach the roof?
  • How much operational comfort you prefer - should the roof window be controlled manually, electrically, or by solar power?
  • Your choice of interior finish (repainting, lining, replastering)

The costs of installing roof windows depend on your preferences

The costs of a roof window installation depend on your roof type, what kind of window solution you choose, and can vary greatly in different areas of the UK.

A VELUX roof window installation can be achieved in as little as four hours. The starting price for the most basic VELUX roof window, the Centre pivot roof window, is £305 excl. VAT. Add to that an average of £100 for flashing plus installation. For the larger VELUX roof balcony option, prices start at £2,559 excl. VAT plus the costs of labour.

Of course, it is well worth investing in more daylight where possible. If you're going through the time and expense of installing roof windows, selecting the bigger option will pay for itself in terms of the finished result.
