Skylight installation in Stevenage: what is involved?
For Stevenage 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Skylight installation suits new extensions, new openings and fit-only jobs.
Jobs in Stevenage are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Do you need permission in Stevenage?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

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.
Can you work alongside my builder in Stevenage?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
