Planning and building regulations for Bletchley
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
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 Bletchley 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 Bletchley
Do I need triple glazing to meet building regulations?
Not usually. Well-specified double glazed lanterns generally meet the limiting values for rooflights. Triple glazing is an upgrade, not normally a requirement. Your building control body can confirm for your project.
Will triple glazing stop rain noise?
It reduces it noticeably. Laminated glass reduces it further.
How quickly can I get a roof lantern in Bletchley?
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 MK3.
Is it worth having solar-control glass in Bletchley?
With the midsummer sun about 61.4° high at noon, roof glass in Bletchley gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
