Planning and building regulations for Portishead
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in Portishead are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from Portishead
Is self-cleaning glass the same as solar-control glass?
No. Self-cleaning is a coating that sheds dirt; solar control reduces heat gain. Many lantern units combine both.
Do I still need to clean self-cleaning glass?
Occasionally. It keeps the glass cleaner for longer, but heavy dirt and droppings still need a gentle rinse, especially in dry spells.
Is it worth having solar-control glass in Portishead?
With the midsummer sun about 62.0° high at noon, roof glass in Portishead gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do you deliver roof lanterns to Portishead?
Yes. Delivery to Portishead (BS20) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
