What are loft conversion skylights?
Across Buckinghamshire, our loft conversion skylights work covers roof windows planned for loft rooms — light, headroom and escape. Survey first, fixed price second, fitting third.
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. Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens.

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.

Common questions
Will the loft be cold near the windows?
Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
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 I need planning permission in Buckinghamshire?
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.
