Planning and building regulations for Dartford
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
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 Dartford 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 Dartford
Is solar control the same as tinted glass?
Solar-control coatings often look slightly tinted, but the performance comes from the coating, not just the colour.
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.
