Planning and building regulations in Hertfordshire

In England, building regulations energy guidance sets a limiting U-value of 2.2 W/m²K for new and replacement rooflights in existing homes, measured horizontally.

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 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.

Solar-control roof lanterns in Hertfordshire: questions

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.

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.

Who checks building regulations for a lantern in Hertfordshire?

Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
