Planning and building regulations for Isleworth
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 Isleworth 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 Isleworth
Can I get a grey uPVC lantern?
Some ranges offer foiled colours. The choice is narrower than aluminium.
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.
Can you fit a roof lantern in Isleworth?
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.
Who checks building regulations for a lantern in Isleworth?
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.
