Planning and building regulations for Harwich
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 in Harwich 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 Harwich
How is a large lantern delivered?
On pallets, usually with the frame and glass packed separately. The heaviest single item is normally a glass unit, which needs two or more people to lift safely.
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.
Do I need planning permission for a roof lantern in Harwich?
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.
Is it worth having solar-control glass in Harwich?
With the midsummer sun about 61.5° high at noon, roof glass in Harwich gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
