Conservation rooflights for Letchworth Garden City: the essentials
We handle conservation rooflights across Hertfordshire, including Letchworth Garden City. In short: slim, low-profile steel-look rooflights for period and listed roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for conservation rooflights include slate and plain-tile roofs where a quiet roofline matters.
Letchworth Garden City sits about 5 km from Hitchin and 9 km from Stevenage, and we cover the whole SG6 postcode district and the roads in between.

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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
