Planning and building regulations for Eltham
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.
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 Eltham 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 Eltham
Will a new lantern be warmer?
A modern double glazed lantern with a thermally broken frame loses far less heat than polycarbonate.
Can I replace polycarbonate panels with glass?
Usually not in the old frame: glass is much heavier than polycarbonate and the frame was not designed for it. Replacing the whole lantern is the safer route.
Who checks building regulations for a lantern in Eltham?
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.
Do I need planning permission for a roof lantern in Eltham?
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.
