Planning and building regulations for Slough
In England, building regulations energy guidance sets a limiting U-value of 2.2 W/m²K for new and replacement rooflights in existing homes, measured horizontally.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in Slough 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 Slough
Can I have an opening vent in a pyramid lantern?
Some ranges can fit a vent in one of the triangular panes, others cannot. We will tell you on the quote whether your chosen range allows 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.
Who checks building regulations for a lantern in Slough?
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.
Do I need planning permission for a roof lantern in Slough?
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.
