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
Can I return a bespoke lantern?
No. Goods made to your specification are excluded from the 14-day cancellation right under the Consumer Contracts Regulations. Your other legal rights, for example if the lantern is faulty, are not affected.
How accurate do my measurements need to be?
Accurate to the millimetre on the outside of the kerb, measured at several points. Kerbs are rarely perfectly square, so measure both diagonals too. Our measuring guide shows how.
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.
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.
