Planning and building regulations for Northampton
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.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Northampton 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 Northampton
Will the colour fade?
Polyester powder coatings are designed for outdoor use and hold their colour well. Coastal sites benefit from occasional washing to remove salt deposits.
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.
How quickly can I get a roof lantern in Northampton?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for NN1.
Do I need planning permission for a roof lantern in Northampton?
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.
