Loft conversion skylights for Llangefni: the essentials
For Llangefni homes and buildings we offer loft conversion skylights: roof windows planned for loft rooms — light, headroom and escape. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. In Llangefni, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
From Llangefni to Bangor, Gwynedd, Caernarfon and Holyhead, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Llangefni
- Blackout and thermal blinds
- Centre-pivot or top-hung
- Balcony roof windows on some ranges
- Combination and stacked layouts
- Electric or solar opening
- Blinds and blackout for bedrooms
- Light planned around the room layout
Before you order: points to check
- Rafter spacing affects window widths
- Escape-window requirements apply to some loft rooms
Do you need permission in Llangefni?
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. 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 Llangefni
Do loft roof windows need to be escape windows?
Some loft rooms need an escape window, depending on the layout and the fire strategy for the conversion. Building control confirms the requirement.
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.
