What are loft conversion skylights?

Loft conversion skylights in South Glamorgan means roof windows planned for loft rooms — light, headroom and escape. Every quote follows a survey of the roof and the room below.

Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting.

Planning and building rules in Wales

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.

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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

How the job runs

  1. Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
  2. Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
  3. Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
  4. Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions

Can you work alongside my loft builder?

Yes — we set out and fit the windows to the builder's programme.

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.

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.

Do I need to be at home for the survey in South Glamorgan?

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
