Planning and building regulations for Watford
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.
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 Watford 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 Watford
Do aluminium lanterns get cold and drip?
Thermally broken frames are designed to reduce cold bridging. Condensation can still form if a room is very humid and poorly ventilated, which is why kitchens and bathrooms need extract ventilation.
Can I paint an aluminium lantern later?
It can be repainted with suitable systems, but it is far better to choose the right powder-coated colour at the start.
Can you fit a roof lantern in Watford?
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.
Do you deliver roof lanterns to Watford?
Yes. Delivery to Watford (WD17) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
