How we approach pitched roof windows in Letchworth Garden City
We handle pitched roof windows across Hertfordshire, including Letchworth Garden City. In short: centre-pivot and top-hung skylights for tiled and slate roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Pitched roof windows suit lofts, attic rooms, landings and vaulted ceilings.
Letchworth Garden City is around 38 km from Watford, and we survey and fit throughout that part of Hertfordshire, including the SG6 district.

- Centre-pivot or top-hung

Before you order: points to check

Planning and building rules for Letchworth Garden City
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.
