Task guide
When this may be needed
- All the lights in one room or area have gone off.
- The lighting MCB trips when a particular light is switched on.
- A light works from one switch of a two-way pair but not the other.
- Lights flicker together or dim when other appliances start.
- Lights stopped working after water leaked from the ceiling.
What the team does
The technician checks the lighting MCB at the distribution board, then tests the switches and light points on the affected circuit. Each fitting is checked for a failed driver, loose terminal or water damage, and switches for worn contacts. The faulty point is found and simple fixes, such as a loose connection, are done on the spot. Parts and fittings are priced before replacement.
Included in this price
- Checking the lighting circuit at the DB box
- Testing switches and light points
- Finding the faulty fitting, switch or connection
- Fixing loose connections, with parts priced first
Limits & price factors
Replacement fittings, LED drivers and switches are priced separately. Water leaks into ceiling lights must be fixed at their source first.
The price starts from $80. Lights in false ceilings, many fittings on one circuit and two-way circuits take longer.
FAQs
The lighting MCB may have tripped, or a shared connection on the circuit has failed. Check the DB box first.
That fitting probably has a fault, such as a failed driver or water inside it. Leave it switched off until it is checked.
No. Switch off the lighting circuit at the DB box and have the fittings checked once the leak is fixed.
