Planning and building regulations for Weymouth
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 Weymouth 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 Weymouth
Can I have cresting without finials, or the other way round?
Usually yes. Ranges treat cresting and finials as options. Tell us what you want and the quote will list each item.
Will a traditional lantern need planning permission?
The style does not change the planning position; size, height and location do. Listed buildings and conservation areas are the main cases where consent is more likely to be needed.

Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for DT4.
Who checks building regulations for a lantern in Weymouth?
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.
