Velux-style roof windows are priced close to standard casements but include a weathering upstand and flashing kit. Installation labour is higher due to roof access.

|---|---|---|
| uPVC | Double | £450 – £1,200 |
| uPVC | Triple | £700 – £1,650 |
| Timber | Double | £1,150 – £3,300 |

Belfast note: Northern Ireland labour costs are lower than GB averages; ferry-inflated material costs partially offset savings.
