Choosing rectangular roof lanterns in Merseyside

The classic double-hipped lantern: a ridge, four sloping sides and the most size choice.

Across Merseyside, the shortest day brings around 7h 29m of daylight and the midsummer sun reaches about 60.0° at noon. A lantern collects light from the bright overhead sky all year, and the right glass keeps the long summer days comfortable.

  • Standard sizes or made to your kerb
  • Suits kitchen-diners and rear extensions
  • Intermediate rafters added on longer lengths
  • Stock anthracite, black or white, or any RAL

Delivery and fitting in Merseyside

Planning and building regulations in Merseyside

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.

Rectangular roof lanterns in Merseyside: questions

Does a longer lantern need extra support?

Long lanterns use intermediate rafters inside the lantern itself. The roof structure around the opening must be designed to carry the lantern's weight; your builder or engineer sizes the trimmers.

Can a rectangular lantern be made to an exact size?

Yes. Made-to-measure lanterns are built to the external kerb size you give us, usually in 10 mm steps within the range's limits. Made-to-measure takes longer than a stock size and cannot be cancelled once ordered, so measure twice.

Which way should the ridge run?

The ridge runs along the longer side. On a square opening there is no ridge and the lantern becomes a pyramid.

Who checks building regulations for a lantern in Merseyside?

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.
