What do conservation rooflights in Pwllheli involve?
Our conservation rooflights service in Pwllheli covers slim, low-profile steel-look rooflights for period and listed roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Typical uses for conservation rooflights include slate and plain-tile roofs where a quiet roofline matters.
From Pwllheli to Porthmadog, Caernarfon and Dolgellau, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Pwllheli
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.
See our building regulations guide for U-values, glazing limits and self-certification.
