The costs of replacing a roof window – how to make a budget for your replacement project

Have you put off replacing your roof windows because it seems like a considerable extra cost? Then read on! Replacing your roof windows is neither as expensive nor as time-consuming as you may think. It all comes down to planning the process and budgeting. Here's all you need to know about the cost of replacing your roof windows. 
Key takeaways
  • Decide if you need a simple like-for-like replacement or if it’s a great chance to upgrade to add more light to your space.
  • The cost of installing a roof window depends on multiple factors such as the replacement window type, size, finish and glazing as well as interior finishes and ease of roof access.
  • VELUX roof windows are a brilliant way to let in more daylight and can help save on energy costs due to their thermal efficiency.

How much does a skylight replacement cost?

The average cost of replacing a roof window varies depending on the kind of roof window that needs replacing. For instance, replacing your out-of-date roof windows with a new like-for-like model is cheaper than replacing it with a larger window. Here's what you need to consider when making a budget for your roof window replacement:

What to include in your skylight replacement budget

The cost of installing a roof window will depend on several different factors, including:

  • The type of window and the types of internal finish and glazing you choose
  • The size of the window and how many windows you want to install
  • Ease of access to the roof and whether scaffolding is required for the installation
  • How you want the roof window to be controlled (manually, electrically, or with solar power)
  • The interior finish (repainting, lining, and replastering)

Start by figuring out what you want from your roof window replacement. This is a great time to consider if your roof windows allow enough daylight to enter your house or if you could do with an upgrade.

The cost of replacing a skylight depends on the kind of replacement you choose

A VELUX roof window replacement can be achieved in as little as four hours and will cost an average of £980 for a 1:1 installation. If you decide to go for larger or multiple roof windows, there will be an additional fee, but it can still be done within a day or two.

Why skylights are a great choice

It's recommended that the glazed area of all windows is no less than 20% of the room's floor area to ensure rooms have adequate daylight levels. Choosing a roof window will allow maximum daylight to enter your home. For instance, a roof window provides up to twice as much light as a façade window of the same size, while flat roof windows can bring up to three times more light. Discover our different solutions to find a roof window to match your needs and budget.
