Planning and building rules in England
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

How do I book a survey in Grantham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Grantham free?

Yes. We survey and fit skylights and rooflights in Grantham and across Lincolnshire. Send your postcode and we will offer a survey date when we reply.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
