Planning and building regulations for Harrow
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 Harrow 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 Harrow
Will white uPVC yellow over time?
Modern uPVC profiles are UV-stabilised and should stay white with normal cleaning. Very old lanterns, especially with polycarbonate panels, are the ones that discolour.
Are uPVC lanterns as good as aluminium?
They do the same job at a lower price, with bulkier frames and fewer colour and size options. For most showpiece extensions aluminium is worth the extra.
Do I need planning permission for a roof lantern in Harrow?
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.
Can you fit a roof lantern in Harrow?
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.
