Sliding rooflights in Aberystwyth: what is involved?
Sliding rooflights in Aberystwyth means box rooflights whose glass lid slides back for walk-out roof access. We cover the SY23 district and the rest of Dyfed, 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. In Aberystwyth, as anywhere, sliding rooflights are the usual choice for walk-out access where a hatch would feel cramped.
From Aberystwyth to Machynlleth, Dolgellau and Llandrindod Wells, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for sliding rooflights in Aberystwyth
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.

Questions about sliding rooflights in Aberystwyth
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.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
Is the survey in Aberystwyth 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 Aberystwyth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
