What does skylight installation in Eastleigh involve?
For Eastleigh homes and buildings we offer skylight installation: survey, supply and fit — new openings, extensions and fit-only work. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Skylight installation suits new extensions, new openings and fit-only jobs.
Eastleigh sits about 8 km from Southampton and 11 km from Winchester, and we cover the whole SO50 postcode district and the roads in between.
Specification options
- New openings with joist trimming
- Fit only (customer-supplied units)
- Internal plaster reveal
- Upstands and flashings
- Supply and fit
- Fit-only for units you have bought
- Free survey for new installations
Things we check at survey
- Work at height is planned with suitable access
- Structural changes may need an engineer's check
Do you need permission in Eastleigh?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Questions about skylight installation in Eastleigh
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
How do I book a survey in Eastleigh?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Eastleigh?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
