Sliding rooflights for Swansea: the essentials
We handle sliding rooflights across West Glamorgan, including Swansea. In short: box rooflights whose glass lid slides back for walk-out roof access. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Typical uses for sliding rooflights include walk-out access where a hatch would feel cramped.
We cover all of Swansea and the SA1 district, and nearby Briton Ferry and Gorseinon.
Specification options
- Electric drive with safety edge
- Box (glazed sides) or flat sliding lid
- Rain sensor
- Integrated balustrade on some ranges
- Double or triple glazing
- Glazed box sides keep the headroom open
- Lockable from inside
Before you order: points to check
- The stair opening and headroom must meet Building Regulations
- Needs space on the roof for the lid to slide clear
Do you need permission in Swansea?
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Common questions
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
