Questions from Ashford (Surrey)
What is the largest square lantern?
Ranges differ. Many go to around 3 m square, with extra hip bars on larger sizes. Tell us your kerb size and we will confirm which ranges can make it.
Will a square lantern leak at the top?
It should not when it is correctly installed and maintained. The apex is factory-designed to shed water; leaks usually come from the upstand or roof membrane rather than the lantern itself, which is why the upstand detail matters.
Do I need planning permission for a roof lantern in Ashford (Surrey)?
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.
Who checks building regulations for a lantern in Ashford (Surrey)?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
