What do pitched roof windows in Chiswick involve?
We handle pitched roof windows across Greater London, including Chiswick. In short: centre-pivot and top-hung skylights for tiled and slate roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Pitched roof windows suit lofts, attic rooms, landings and vaulted ceilings.
Chiswick sits about 2 km from Hammersmith and 2 km from Acton, and we cover the whole W4 postcode district and the roads in between.
What you can choose
- Flashings for tiles, slates or recessed fitting
- Manual, electric or solar-powered opening
- Centre-pivot or top-hung
- Integral blinds and shutters
- Double or triple glazing
- Usually fitted in a day
- Flashings to suit tiles or slates
Things we check at survey
- Rafters may need trimming for wider windows
- Insulation collars and vapour control must be detailed
Consents for pitched roof windows in Chiswick
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.

Common questions
Will it need building regulations approval?
Fitting a new roof window usually involves cutting rafters and changing the thermal envelope, so building control approval (or, in England and Wales, a competent-person route) is normally needed. We tell you which applies.
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
Do I need planning permission for a roof window?
Often not, under householder permitted development, provided it does not project too far above the roof plane and conditions are met. Listed buildings, flats and some conservation areas are different. Our planning guide covers each nation.
How do I book a survey in Chiswick?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Chiswick?
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.
