Daylight and sunlight assessment in Wales
26 providers offering daylight and sunlight assessment in or across Wales, including national firms. The rules in Wales differ from England’s, so see the notes below.
The rules in Wales
The BRE guidance is used by Welsh councils too, and planning is decided by your local planning authority. The Prescription Act 1832 extends to Wales, so the 20-year rule on rights to light is the same as in England, but take advice for your case.

Getting signed off in Wales
Building control in Wales works much like England. Your council or a registered building control approver checks the work and issues a completion or final certificate. Wales has its own Approved Documents, and all new and converted homes must have sprinklers.
