* You are replacing accessories such as socket outlets, control switches and ceiling roses.
* You are replacing the cable for a single circuit only where it has been damaged, for example, by fire, rodents or impact, provided that the replacement cable has the same current carrying capacity, follows the same route and does not serve more than one sub-circuit through a distribution board.
* Refixing or replacing the enclosures of existing installation components, if the circuit's protective measures are unaffected.
* Providing mechanical protection to existing fixed installations if the circuit's protective measures and current carrying capacity are unaffected by increased thermal insulation.
* Adding lighting points (light fittings and switches) to an existing circuit, provided that it is not in a kitchen or a special location and only if the existing circuit protective device is suitable and provides protection for the modified circuit, and other relevant safety provisions are satisfactory.
* Adding socket outlets and fused spurs to an existing ring or radial circuit, provided that it is not in a kitchen or a special location and only if the existing circuit protective device is suitable and provides protection for the modified circuit, and other relevant safety provisions are satisfactory.
