Task guide
When this may be needed
- Half the home has power and the other half doesn't.
- The sockets work but the lights don't, or the other way round.
- No breaker appears tripped, yet a circuit is dead.
- Lights dim when a large appliance starts.
- The power went partly off after a thunderstorm.
What the team does
The technician checks whether neighbours are affected, which points to the supply, then inspects the distribution board for tripped or failed breakers and loose or burnt connections. The dead circuits are tested from the board outward. A failed breaker or loose connection is identified and the repair priced. If the fault is in SP Group's supply, you are advised to call SP Group's 24-hour hotline.

FAQs
A breaker has tripped or failed, or a connection at the distribution board has loosened. Check the DB box for a switch in the off or middle position.
It is likely a supply fault. Call SP Group's 24-hour hotline on 1800 778 8888.
A loose connection or an overloaded circuit can drop the voltage when a large load starts. It should be checked, as loose connections can overheat.
