Rooflights for Harpenden homes and buildings
SkylightCompany.uk covers Harpenden and the surrounding part of Hertfordshire, from a single roof window in a loft to a glass link or a warehouse roof.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens.
We work across Hertfordshire, including Harpenden, and in neighbouring towns such as St Albans and Luton. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules in England
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.
