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.

Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.

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.

Small roof lanterns in Greater London: questions

What is the smallest roof lantern?

Many ranges start at around 800–1000 mm. Below that, a flat rooflight is usually the better product.

Can I fit a small lantern myself?

Small lanterns are within the reach of a competent builder or roofer. The critical parts are a level, square, weatherproof upstand and the manufacturer's fixing instructions. In existing homes, replacement rooflights are building work that may need building control involvement.

Are small lanterns available quickly?

Standard small sizes are often available from stock. Lead times are confirmed on your quote.

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.
