For a single standard Velux window, supply and installation, most UK homeowners can expect to pay somewhere in the region of £900 to £2,500, depending on size and complexity.
What's Included in That Range
- The window unit itself — smaller centre-pivot models sit at the lower end, larger or top-hung models higher
- A correctly matched flashing kit for your roof covering
- Labour for a straightforward installation with reasonable access
- Basic internal finishing around the opening
What Pushes the Price Higher
- Larger window sizes or premium models (electric, solar-powered)
- Difficult access requiring scaffolding
- Structural alterations to rafters for a non-standard opening
- Flat roof applications, which use a different, more involved product
What Can Bring It Down
- Choosing a smaller, standard centre-pivot model
- A genuine alternative brand like Fakro or Keylite
- Installing multiple windows in the same visit to share labour and access costs
