How we approach loft conversion skylights in Portslade
Thinking about loft conversion skylights in Portslade? The short answer: roof windows planned for loft rooms — light, headroom and escape. The longer answer depends on your roof, which is why we survey before we price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of loft conversion skylights for attic bedrooms, offices and en-suites.
We work across East Sussex, including Portslade, and in neighbouring towns such as Hove and Brighton. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Portslade
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.
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. 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
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
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 Portslade?
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.
