What do loft conversion skylights in Coulsdon involve?
Loft conversion skylights in Coulsdon means roof windows planned for loft rooms — light, headroom and escape. We cover the CR5 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. In Coulsdon, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
Coulsdon sits about 3 km from Purley and 5 km from Banstead, and we cover the whole CR5 postcode district and the roads in between.

Planning, building control and Coulsdon
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
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.
Will I need planning permission in Coulsdon?
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 Coulsdon?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
