Anthracite grey roof lanterns for Hanworth homes
RAL 7016 anthracite grey, a widely chosen colour to match grey doors and windows.
In midsummer the noon sun stands about 62.0° high over Hanworth, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Matches most grey bifold and sliding doors
- Any other RAL grey on request
- White inside to keep ceilings bright

Planning and building regulations for Hanworth
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.
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 Hanworth 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 Hanworth
Is anthracite grey the same as RAL 7016?
Yes. Some suppliers call it slate grey or charcoal grey, which can cause confusion, so always check the RAL number.
Does anthracite show dirt?
Less than white. Dust and pollen are more visible on dark gloss finishes, which is why most grey lanterns use a matt or textured finish.
How quickly can I get a roof lantern in Hanworth?
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 TW13.
Do I need planning permission for a roof lantern in Hanworth?
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.
