In England, building regulations energy guidance sets a limiting U-value of 2.2 W/m²K for new and replacement rooflights in existing homes, measured horizontally.
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 Rochester 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 Rochester
Does a longer lantern need extra support?
Long lanterns use intermediate rafters inside the lantern itself. The roof structure around the opening must be designed to carry the lantern's weight; your builder or engineer sizes the trimmers.
Which way should the ridge run?
The ridge runs along the longer side. On a square opening there is no ridge and the lantern becomes a pyramid.
Who checks building regulations for a lantern in Rochester?
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.
