The costs of adding roof windows to a room - how to budget for your daylight upgrade

Adding more daylight from above is a very impactful way to transform your home. Yet many believe that adding roof windows is both time-consuming and costly. We're here to tell you otherwise.  


Adding roof windows is not as expensive and complicated as you might think. It all comes down to good planning and budgeting. Here's all you need to know about the costs of adding roof windows and how to budget for this home project. 
Key takeaways
  • When budgeting for your daylight upgrade, consider the type, size and number of roof windows you want, as well as choosing between manual, electric or solar operation.
  • Roof windows can help you save on energy costs. A VELUX roof window with triple-glazing gives you ultimate thermal efficiency, optimal energy efficiency, and indoor comfort.
  • To ensure that your rooms have adequate daylight levels, the glazed area of all windows should be no less than 20% of the floor area.

The costs of a roof window installation

Making a budget is an excellent place to start if you want to add roof windows and make a daylight upgrade to your home. A budget gives you peace of mind and helps you get off to a good start.

Here's what you need to consider:

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.
