How we approach sliding rooflights in Gorseinon
Sliding rooflights in Gorseinon means box rooflights whose glass lid slides back for walk-out roof access. We cover the SA4 district and the rest of West Glamorgan, with a survey before any price is fixed.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Think of sliding rooflights for staircases that rise to a roof terrace.
Neighbouring towns include Llanelli (8 km) and Swansea (9 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Gorseinon
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. 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.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
Read the planning permission guide before you commit to a design.

Common questions
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
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.
Will I need planning permission in Gorseinon?
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.
How do I book a survey in Gorseinon?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
