Planning and building regulations for Clacton-on-Sea
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.
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 Clacton-on-Sea 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 Clacton-on-Sea
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.
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.
Can you fit a roof lantern in Clacton-on-Sea?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Do you deliver roof lanterns to Clacton-on-Sea?
Yes. Delivery to Clacton-on-Sea (CO15) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
