How we approach loft conversion skylights in Carmarthen
We handle loft conversion skylights across Dyfed, including Carmarthen. In short: roof windows planned for loft rooms — light, headroom and escape. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Loft conversion skylights suit attic bedrooms, offices and en-suites.
Carmarthen is around 22 km from Llanelli, and we survey and fit throughout that part of Dyfed, including the SA31 district.

Planning, building control and Carmarthen
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
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.

Questions about loft conversion skylights in Carmarthen
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.
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
Will the loft be cold near the windows?
Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
Is the survey in Carmarthen 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 Carmarthen?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
