Planning and building regulations for Risca
Wales sets its own energy standards for rooflights in the Welsh Approved Document L, so the Welsh figures apply rather than England's.
Permitted development rules in Wales are set separately, so check with your council, especially for listed buildings and conservation areas.
Building regulations in Risca are checked by your local authority building control team. Replacing a rooflight in an existing home is building work in Wales too. A competent person scheme installer can self-certify; otherwise building control should be notified.

Questions from Risca
What is the biggest roof lantern you can supply?
It depends on the range. Some go to about 6 m by 4 m with intermediate rafters. Send us your kerb size and we will confirm what can be made.
Do large lanterns overheat a room?
A large area of south-facing glass can make a room warm on sunny days. Solar-control glass, an opening vent and good background ventilation all help. Our guide on overheating explains the options.
Do I need planning permission for a roof lantern in Risca?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your county or county borough council before ordering.
Can you fit a roof lantern in Risca?
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.
