Planning and building regulations for Haverhill
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.
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 Haverhill 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 Haverhill
Do I need an upstand for a roof lantern?
Yes. Lanterns are designed to sit on an upstand, never directly on the roof deck.
Can I order a lantern before the upstand is built?
Yes, if you build the upstand to the lantern's stated external size. Many people order the lantern and upstand together so they match.
Who checks building regulations for a lantern in Haverhill?
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 Haverhill?
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.
