Planning and building regulations for Winchester
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 Winchester 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 Winchester
Can a vent be added later?
Usually not to an existing fixed lantern. Decide before ordering.
What happens if it rains while the vent is open?
With a rain sensor the vent closes automatically. Without one it stays where you left it, so a sensor is worth having.
How quickly can I get a roof lantern in Winchester?
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 SO23.
Is it worth having solar-control glass in Winchester?
With the midsummer sun about 62.4° high at noon, roof glass in Winchester gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
