What do loft conversion skylights in Dulwich involve?
Loft conversion skylights in Dulwich means roof windows planned for loft rooms — light, headroom and escape. We cover the SE21 district and the rest of Greater London, with a survey before any price is fixed.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Typical uses for loft conversion skylights include attic bedrooms, offices and en-suites.
From Dulwich to Brixton, Peckham and Lewisham, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Dulwich
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.
Read the planning permission guide before you commit to a design.

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.
Will the loft be cold near the windows?
Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
Will I need planning permission in Dulwich?
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 Dulwich?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
