Planning and building regulations for Horsham
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.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
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 the coating be damaged?
Yes, by abrasive cleaning, some chemicals and silicone. Follow the care instructions supplied with your lantern.
Does it work under trees?
Less well. Sap and leaf debris build up faster than daylight and rain can deal with them, so lanterns under trees need more regular rinsing.
Do you deliver roof lanterns to Horsham?
Yes. Delivery to Horsham (RH12) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
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.
