Pitched roof windows for Chelmsford: the essentials
We handle pitched roof windows across Essex, including Chelmsford. 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 homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. In Chelmsford, as anywhere, pitched roof windows are the usual choice for pitched roofs over bedrooms, stairs and bathrooms.
Chelmsford is around 28 km from Southend-on-Sea, and we survey and fit throughout that part of Essex, including the CM1 district.

Do you need permission in Chelmsford?
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.
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. 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
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 roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
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.
