Planning and building regulations for Portsmouth
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.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in Portsmouth 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 Portsmouth
Can I collect?
Ask us when you request your quote. Collection depends on where your lantern is made.
Can you deliver to Scotland, Northern Ireland or the islands?
Mainland Britain is standard. The Scottish Highlands, islands and Northern Ireland are by arrangement, with delivery confirmed on your quote.
Do I need planning permission for a roof lantern in Portsmouth?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
Who checks building regulations for a lantern in Portsmouth?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
