Planning and building regulations in Essex

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.

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 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.

Large roof lanterns in Essex: questions

What is the biggest roof lantern you can supply?

It depends on the range. Some go to about 6 m by 4 m with intermediate rafters. Send us your kerb size and we will confirm what can be made.

Does a large lantern need structural calculations?

The roof structure around it usually does. Your engineer or building control body will want the lantern's weight and the opening size.

Do large lanterns overheat a room?

A large area of south-facing glass can make a room warm on sunny days. Solar-control glass, an opening vent and good background ventilation all help. Our guide on overheating explains the options.

Do I need planning permission for a roof lantern in Essex?

Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
