From initial survey through installation to internal finishing and cleanup
Most VELUX roof window installations fall under permitted development and don't require planning permission. However, you may need approval if your property is listed, in a conservation area, or if the windows project more than 150mm from the roof slope.
A single VELUX window installation typically costs £800-£1,500 including the window, flashing kit, and labour. Prices vary based on window size, glazing specification, and access requirements. Electric or solar-powered windows cost more. We provide detailed, no-obligation quotes after surveying your property.
Modern VELUX windows come with solar control glazing options that reduce heat gain by up to 77% while still letting natural light through. We recommend solar control glass for south-facing installations. Blinds and external awnings provide additional heat management options.
A single VELUX roof window can typically be installed in one day, including cutting the opening, fitting the window and flashing, and basic internal trimming. Roof lanterns and larger installations may take 2-3 days. Plastering and final decoration are usually done separately.
Skylights are flat or low-profile glazed units that sit flush with the roof, ideal for flat roofs or simple installations. Roof lanterns are raised, multi-panel glass structures creating a more dramatic architectural feature with greater headroom and more glass area for maximum light.
VELUX windows can be installed in most roof types with pitches between 15° and 90°. Different flashing kits accommodate slate, tile, flat, and profiled roofing materials. For very low-pitch or flat roofs, we recommend flat roof skylights or roof lanterns instead of traditional roof windows.
