Loft conversion skylights in Swansea: what is involved?
Loft conversion skylights in Swansea means roof windows planned for loft rooms — light, headroom and escape. We cover the SA1 district and the rest of West Glamorgan, with a survey before any price is fixed.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Think of loft conversion skylights for loft conversions and rooms in the roof.
We cover all of Swansea and the SA1 district, and nearby Briton Ferry and Gorseinon.

Do you need permission in Swansea?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. 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.
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 many roof windows does a loft room need?
Enough to give good light — a common rule of thumb is glazing equal to roughly a tenth to a fifth of the floor area, adjusted for orientation and use. We advise at survey.
Top-hung or centre-pivot in a loft?
Top-hung gives a clearer view and often suits escape use; centre-pivot is easier to clean and suits higher positions.
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
Is the survey in Swansea free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Swansea?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
