Planning and building regulations in Greater London

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 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.

Bespoke roof lanterns in Greater London: questions

Will I see a drawing before it is made?

For made-to-measure and special shapes, yes: the order is based on a drawing you approve, so the size you check is the size that gets made.

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.

Do bespoke lanterns cost much more?

For simple rectangles the premium over a stock size is usually modest. Special shapes cost more because each one is engineered individually.

Who checks building regulations for a lantern in Greater London?

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.
