Sun tunnels & tubular skylights for Letchworth Garden City: the essentials
For Letchworth Garden City homes and buildings we offer sun tunnels & tubular skylights: light pipes that bring daylight to halls and bathrooms with no window. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
Letchworth Garden City is around 38 km from Watford, and we survey and fit throughout that part of Hertfordshire, including the SG6 district.
What you can choose
- Pitched or flat-roof flashings
- Rigid (brighter) or flexible tubes
- Insulated tube sections
- Integrated electric light
- Diffusers in several sizes
- Works on pitched and flat roofs
- Low maintenance
Things we check at survey
- Gives light, not a view
- Light output falls with tube length and bends
Consents for sun tunnels & tubular skylights in Letchworth Garden City
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.
