What do sun tunnels & tubular skylights in Merthyr Tydfil involve?
Sun tunnels & tubular skylights in Merthyr Tydfil means light pipes that bring daylight to halls and bathrooms with no window. We cover the CF47 district and the rest of Mid Glamorgan, with a survey before any price is fixed.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Think of sun tunnels & tubular skylights for small internal rooms where a full rooflight will not fit.
From Merthyr Tydfil to Aberdare, Rhondda and Ebbw Vale, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for sun tunnels & tubular skylights in Merthyr Tydfil
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. 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. 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.
