Pitched roof windows for Portishead: the essentials
For Portishead homes and buildings we offer pitched roof windows: centre-pivot and top-hung skylights for tiled and slate roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Think of pitched roof windows for pitched roofs over bedrooms, stairs and bathrooms.
Portishead is around 31 km from Bath, and we survey and fit throughout that part of Somerset, including the BS20 district.

Planning, building control and Portishead
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. 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. 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.

Questions about pitched roof windows in Portishead
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.
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.
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.
Can you work alongside my builder in Portishead?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Portishead?
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.
