Loft conversions, dark rear extensions and north-facing rooms across Southampton's Victorian and post-war housing stock are commonly under-lit. Velux roof windows and flat roof skylights are the most effective and least disruptive way to bring natural light into these spaces. We supply and fit, or fit-only from your own supply, across all Southampton postcodes and Hampshire.
Velux and skylight installation in Southampton costs £600 to £1,800 supply-and-fit, bringing light into loft conversions and extensions. We use correct flashing kits for slate, clay and concrete tile, with free quotes and full insurance. Covering Southampton and Hampshire. Call 0238 184 9628.
A roof window or skylight transforms the living quality of loft conversions, top-floor bedrooms and dark rear rooms. In Southampton's Victorian terraced streets — where deep terraces create poorly-lit rear rooms — flat roof skylights over single-storey extensions have become one of the most requested home improvement jobs we carry out.
Velux roof windows are the standard for pitched roof installations. The Centre-Pivot range (GGL) is the most common for habitable loft spaces. For maintenance access or where opening is less critical, the Top-Hung (GGU) offers a cleaner internal finish. Installation requires careful flashing integration with the existing roof covering — on Welsh slate and clay tile roofs we install slate or tile flashing kits that maintain the watertight envelope properly.
Flat roof skylights — fixed-light or opening — are now a standard feature of rear kitchen and dining room extensions across Southampton. The most common specification is a double-glazed polycarbonate or glass unit on an upstand, integrated into a GRP or EPDM flat roof. We can install skylights into new flat roofs as part of a replacement job, or into existing flat roofs where the deck is sound.
Sun tunnels (Velux TWR) channel daylight from the roof to interior spaces below via a reflective tube — useful where full skylight installation is not practical, typically in bathrooms, hallways and landings. They are significantly cheaper than full skylights and require minimal structural work.
Most single roof window installations on non-principal elevations are permitted development. Front elevation or principal elevation windows on properties in conservation areas may require planning permission. We advise on planning implications during the free survey.

"Three Velux windows in our loft conversion in Bitterne. The flashing on the Welsh slate was done properly — not a drop of water has come in over two winters. Excellent installation."
"Flat roof skylight over our rear extension in Highfield. They installed it as part of the flat roof replacement — seamless integration, beautifully lit room."
"Sun tunnel in our hallway — completely transformed a dark space. Took three hours, looks great, minimal disruption."
Velux supply and fit on a standard pitched roof: £600 to £1,200. Fit-only: £300 to £500. Flat roof skylight supply and fit: £800 to £1,800. Sun tunnel installation: £350 to £700. Free quotes on all Velux and skylight work.
Most single Velux installations on non-principal elevations are permitted development. Front elevation or principal elevation windows in conservation areas may require planning permission. Windows that protrude more than 150mm above the roof pitch require permission. We advise on this during the free survey.
Yes. We use Velux-approved slate flashing kits that integrate the window frame correctly with slate covering. Correct flashing integration is critical — a poorly flashed Velux window on a slate roof leaks within the first wet winter.
Velux is a brand name — their products include both opening roof windows and fixed rooflights. A rooflight or skylight is a broader term covering fixed-light units, typically on flat roofs, as well as opening windows. We install both.
Yes, provided the deck structure is sound. We assess the deck during survey. If the flat roof is due for replacement, installing a skylight as part of the replacement job is the most cost-effective approach.
A single Velux window installation typically takes half a day to a full day including flashings. Multiple windows take proportionally longer. Flat roof skylights take a full day to integrate with the flat roof system correctly.
