Planning and building regulations for Daventry
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.
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 Daventry 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 Daventry
What is the difference between an orangery and a conservatory?
A conservatory has a mostly glazed roof; an orangery has a mostly solid roof with a lantern in the middle and usually more solid wall. Orangeries are easier to keep comfortable year round.
Can I add a lantern to my existing orangery roof?
If the roof has a suitable opening and upstand, yes. If not, the roof needs structural alteration first, which is a job for a builder with an engineer's input.
Who checks building regulations for a lantern in Daventry?
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.
Is it worth having solar-control glass in Daventry?
With the midsummer sun about 61.2° high at noon, roof glass in Daventry gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
