Planning and building regulations for Chester-le-Street
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.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Chester-le-Street 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 Chester-le-Street
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.
Can you fit a roof lantern in Chester-le-Street?
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.
Is it worth having solar-control glass in Chester-le-Street?
With the midsummer sun about 58.6° high at noon, roof glass in Chester-le-Street gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
