Planning and building regulations for Portsmouth
England's Approved Document L caps the U-value of new or replacement rooflights in existing homes at 2.2 W/m²K, calculated with the glass horizontal.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
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
Is aluminium recyclable?
Yes, aluminium can be recycled repeatedly. Ask your local waste site about the glass and seals, which are handled separately.
Will the colour fade?
Polyester powder coatings are designed for outdoor use and hold their colour well. Coastal sites benefit from occasional washing to remove salt deposits.
Is it worth having solar-control glass in Portsmouth?
With the midsummer sun about 62.6° high at noon, roof glass in Portsmouth gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Can you fit a roof lantern in Portsmouth?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
