Conservation rooflights for Machynlleth: the essentials
We handle conservation rooflights across Powys, including Machynlleth. In short: slim, low-profile steel-look rooflights for period and listed roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. In Machynlleth, as anywhere, conservation rooflights are the usual choice for period, listed and conservation-area roofs.
Neighbouring towns include Dolgellau (17 km) and Aberystwyth (25 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Machynlleth
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. 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.
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.
