Loft conversion skylights for Letchworth Garden City: the essentials

Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for loft conversion skylights include attic bedrooms, offices and en-suites.

Planning and building rules for 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Questions about loft conversion skylights in Letchworth Garden City
Do loft roof windows need to be escape windows?
Some loft rooms need an escape window, depending on the layout and the fire strategy for the conversion. Building control confirms the requirement.
Will the loft be cold near the windows?
Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
Top-hung or centre-pivot in a loft?
Top-hung gives a clearer view and often suits escape use; centre-pivot is easier to clean and suits higher positions.
Will I need planning permission in Letchworth Garden City?
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.
Do I need to be at home for the survey in Letchworth Garden City?
