Planning and building regulations for Farnham
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.
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 Farnham 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 Farnham
Do orangery lanterns come with cresting?
They can. Cresting and finials are options on traditional ranges.
Can I add a lantern to my existing orangery roof?
If the roof has a suitable opening and upstand, yes. If not, the roof needs structural alteration first, which is a job for a builder with an engineer's input.
Who checks building regulations for a lantern in Farnham?
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.
Is it worth having solar-control glass in Farnham?
With the midsummer sun about 62.2° high at noon, roof glass in Farnham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
