Planning and building regulations for Egham
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 Egham 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 Egham
Will a new lantern be warmer?
A modern double glazed lantern with a thermally broken frame loses far less heat than polycarbonate.
My old lantern leaks. Is it the lantern or the roof?
Often the roof or kerb detailing. A survey or close inspection will tell. If the lantern is the problem, replacing it is usually better value than repairing old polycarbonate.
Do you deliver roof lanterns to Egham?
Yes. Delivery to Egham (TW20) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Is it worth having solar-control glass in Egham?
With the midsummer sun about 62.0° high at noon, roof glass in Egham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
