Loft conversion skylights for Cheshunt: the essentials
Our loft conversion skylights service in Cheshunt covers roof windows planned for loft rooms — light, headroom and escape. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Cheshunt, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
We work across Hertfordshire, including Cheshunt, and in neighbouring towns such as Waltham Abbey and Enfield. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Cheshunt
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. 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.

Common questions
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.
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 the loft be cold near the windows?
Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
Will I need planning permission in Cheshunt?
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.
Can you work alongside my builder in Cheshunt?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
