Bespoke roof lanterns for Chelsea homes
Made to your exact kerb size, including long, gable-ended and L-shaped designs.
In midsummer the noon sun stands about 62.0° high over Chelsea, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Gable-ended and L-shaped designs on request
- Approval drawing before manufacture
- Choose bar layout and vent position

Planning and building regulations for Chelsea
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 Chelsea 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 Chelsea
Can I return a bespoke lantern?
No. Goods made to your specification are excluded from the 14-day cancellation right under the Consumer Contracts Regulations. Your other legal rights, for example if the lantern is faulty, are not affected.
How accurate do my measurements need to be?
Accurate to the millimetre on the outside of the kerb, measured at several points. Kerbs are rarely perfectly square, so measure both diagonals too. Our measuring guide shows how.
Is it worth having solar-control glass in Chelsea?
With the midsummer sun about 62.0° high at noon, roof glass in Chelsea gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Can you fit a roof lantern in Chelsea?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
