Planning and building regulations in Lancashire

In England, building regulations energy guidance sets a limiting U-value of 2.2 W/m²K for new and replacement rooflights in existing homes, measured horizontally.

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 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.

Self-cleaning glass roof lanterns in Lancashire: questions

Does it work under trees?

Less well. Sap and leaf debris build up faster than daylight and rain can deal with them, so lanterns under trees need more regular rinsing.

Is self-cleaning glass the same as solar-control glass?

No. Self-cleaning is a coating that sheds dirt; solar control reduces heat gain. Many lantern units combine both.

Do I still need to clean self-cleaning glass?

Occasionally. It keeps the glass cleaner for longer, but heavy dirt and droppings still need a gentle rinse, especially in dry spells.

How quickly can I get a roof lantern in Lancashire?

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 Lancashire.
