Planning and building rules for St Austell
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. 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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about pitched roof windows in St Austell
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.
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 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 I need planning permission in St Austell?
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.
