Planning and building regulations for Isleworth
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.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in Isleworth 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 Isleworth
What is the smallest roof lantern?
Many ranges start at around 800–1000 mm. Below that, a flat rooflight is usually the better product.
Can I fit a small lantern myself?
Small lanterns are within the reach of a competent builder or roofer. The critical parts are a level, square, weatherproof upstand and the manufacturer's fixing instructions. In existing homes, replacement rooflights are building work that may need building control involvement.
Is it worth having solar-control glass in Isleworth?
With the midsummer sun about 62.0° high at noon, roof glass in Isleworth gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do I need planning permission for a roof lantern in Isleworth?
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.
