How we approach sliding rooflights in Porthcawl
Our sliding rooflights service in Porthcawl covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Sliding rooflights suit staircases that rise to a roof terrace.
From Porthcawl to Bridgend, Port Talbot and Maesteg, the same survey-first process applies: measure, specify, fix the price, then fit.

- Electric drive with safety edge

Before you order: points to check
- Electric units need a dedicated supply and commissioning
- Needs space on the roof for the lid to slide clear
Consents for sliding rooflights in Porthcawl
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
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.
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
Do you fit sliding rooflights in Porthcawl?
Yes. We survey and fit sliding rooflights in Porthcawl and across Mid Glamorgan. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Porthcawl?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
