Consents for bespoke & shaped rooflights in Portishead
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. 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.

Bespoke & shaped rooflights in Portishead: questions
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Is the survey in Portishead free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in 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.
