Building regulations advice
Building regulations are national standards which apply to all types of building or alterations and cover all aspects of construction.
Part P of the building regulations deals with electrical work.
Any electrical work carried out by non-registered traders should be checked and certified and the property owner is responsible for ensuring electrical work complies with the rules.
