Planning and building regulations for Greenwich
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.
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 Greenwich 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 Greenwich
Do you need to survey before fitting?
For a lantern on a ready upstand, clear photos and measurements are often enough. Replacements and new openings need a survey.
Can you build the upstand as well?
We can quote for upstands and associated roofing on a survey basis.
How quickly can I get a roof lantern in Greenwich?
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 SE10.
Is it worth having solar-control glass in Greenwich?
With the midsummer sun about 62.0° high at noon, roof glass in Greenwich gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
