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 Crowborough 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 Crowborough
What height should my upstand be?
High enough to keep water away from the lantern seal, commonly at least 150 mm above the finished roof surface. Follow the instructions for your chosen range.
Who makes the upstand weatherproof?
Your roofer, by dressing the roof membrane up the outside of the upstand. The lantern then sits over it.
Do I need planning permission for a roof lantern in Crowborough?
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.
Is it worth having solar-control glass in Crowborough?
With the midsummer sun about 62.4° high at noon, roof glass in Crowborough gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
