Skylight installation in Monmouth: what is involved?
Skylight installation in Monmouth means survey, supply and fit — new openings, extensions and fit-only work. We cover the NP25 district and the rest of Gwent, with a survey before any price is fixed.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
From Monmouth to Abergavenny, Pontypool and Cwmbran, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight installation in Monmouth
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. 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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.
