Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from St Helens
Does it help in winter?
Solar control mainly limits summer heat. Winter heat loss is governed by the U-value, which depends on the glazing unit and frame.
Can blinds do the same job?
Internal blinds reduce glare but the heat is already inside the room. Glass that stops the heat at the roof is more effective.
Do I need planning permission for a roof lantern in St Helens?
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.
How quickly can I get a roof lantern in St Helens?
