Questions from Stevenage
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.
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.
Do I need planning permission for a roof lantern in Stevenage?
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 Stevenage?
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.
