Rectangular roof lanterns for Sittingbourne homes
The classic double-hipped lantern: a ridge, four sloping sides and the most size choice.
In midsummer the noon sun stands about 62.1° high over Sittingbourne, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.

Planning and building regulations for Sittingbourne
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 Sittingbourne 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 Sittingbourne
Can a rectangular lantern be made to an exact size?
Yes. Made-to-measure lanterns are built to the external kerb size you give us, usually in 10 mm steps within the range's limits. Made-to-measure takes longer than a stock size and cannot be cancelled once ordered, so measure twice.
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.
Is it worth having solar-control glass in Sittingbourne?
With the midsummer sun about 62.1° high at noon, roof glass in Sittingbourne gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
How quickly can I get a roof lantern in Sittingbourne?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for ME10.
