Planning and building regulations for St Helens
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 in St Helens 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 St Helens
Should the lantern match my bifold doors?
A common choice is to match the outside colour, often anthracite. The inside can be white to keep the ceiling bright.
Can I add a lantern to my existing orangery roof?
If the roof has a suitable opening and upstand, yes. If not, the roof needs structural alteration first, which is a job for a builder with an engineer's input.
Is it worth having solar-control glass in St Helens?
With the midsummer sun about 60.0° high at noon, roof glass in St Helens gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
