Sun tunnels & tubular skylights for Sherborne: the essentials
Our sun tunnels & tubular skylights service in Sherborne covers light pipes that bring daylight to halls and bathrooms with no window. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
Sherborne sits about 8 km from Yeovil and 26 km from Dorchester, and we cover the whole DT9 postcode district and the roads in between.

Consents for sun tunnels & tubular skylights in Sherborne
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
