Planning and building regulations for Horsham
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
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 Horsham 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 Horsham
Can I replace polycarbonate panels with glass?
Usually not in the old frame: glass is much heavier than polycarbonate and the frame was not designed for it. Replacing the whole lantern is the safer route.
How long does replacement take on site?
For a like-for-like swap on a sound kerb, often a day. Kerb or roof repairs add time.
Do I need planning permission for a roof lantern in Horsham?
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 Horsham?
With the midsummer sun about 62.4° high at noon, roof glass in Horsham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
