Planning and building regulations for Slough
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 Slough 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 Slough
Can a rectangular lantern be made to an exact size?
Yes. Made-to-measure lanterns are built to the external kerb size you give us, usually in 10 mm steps within the range's limits. Made-to-measure takes longer than a stock size and cannot be cancelled once ordered, so measure twice.
What is the most common rectangular roof lantern size?
Sizes of 1000 × 2000 mm and 1500 × 2500 mm are common standard sizes for kitchen and dining extensions, but the right size is the one that matches your kerb. If your kerb is not built yet, our sizes guide helps you pick a standard size first.
Can you fit a roof lantern in Slough?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Is it worth having solar-control glass in Slough?
With the midsummer sun about 61.9° high at noon, roof glass in Slough gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
