Planning and building regulations for Welwyn Garden City
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 Welwyn Garden City 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 Welwyn Garden City
Do bespoke lanterns cost much more?
For simple rectangles the premium over a stock size is usually modest. Special shapes cost more because each one is engineered individually.
Can I return a bespoke lantern?
No. Goods made to your specification are excluded from the 14-day cancellation right under the Consumer Contracts Regulations. Your other legal rights, for example if the lantern is faulty, are not affected.
Is it worth having solar-control glass in Welwyn Garden City?
With the midsummer sun about 61.6° high at noon, roof glass in Welwyn Garden City gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Who checks building regulations for a lantern in Welwyn Garden City?
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.
