Pitched roof windows for Gerrards Cross: the essentials
Our pitched roof windows service in Gerrards Cross covers centre-pivot and top-hung skylights for tiled and slate roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written 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 pitched roof windows for lofts, attic rooms, landings and vaulted ceilings.

Planning, building control and Gerrards Cross
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. 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.
Read the planning permission guide before you commit to a design.

Pitched roof windows in Gerrards Cross: questions
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.
Can a roof window be fitted from inside?
In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
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.
How do I book a survey in Gerrards Cross?
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 Gerrards Cross?
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.
