How we approach sun tunnels & tubular skylights in Redruth
Sun tunnels & tubular skylights in Redruth means light pipes that bring daylight to halls and bathrooms with no window. We cover the TR15 district and the rest of Cornwall, with a survey before any price is fixed.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Think of sun tunnels & tubular skylights for small internal rooms where a full rooflight will not fit.
Redruth is around 13 km from Truro, and we survey and fit throughout that part of Cornwall, including the TR15 district.

Planning and building rules for Redruth
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
