When buying a loft skylight, there are a number of choices to consider. Check below all the choices that affect the price while buying a roof window.

Choice 3: Finishing
When buying a skylight, the price of finishing is not always included. Finishing consists of timbering the inside of the roof. This may also include kitting and plastering or painting the skylight. The price of finishing depends on the depth of the roof. Check below the average prices of finishing when buying a skylight.

Choice 4: Additional options
There are a number of additional options that affect the price of buying a skylight. The 2 choices are the type of blackout and the choice of an electric skylight. The most common type of blackout is a roller blind. You place this between the internal windows, blocking out almost all light. It is an addition to your skylight, but does increase the price when you go to buy your skylight. Read more about the average prices of these extra options here.
| Extra option | Average price when buying a skylight including installation and VAT |
|---|---|
| Dormer window | £ 60 – £ 220 |
