A flickering light can be a nuisance, but the important first question is how much of the installation is affected. One lamp behaving differently from the rest gives a different starting point from several rooms dimming together. Neither pattern is a diagnosis on its own.
For a Discovery property, a short event record helps an electrician choose a sensible investigation. Do not open fittings, tighten internal connections or remove the distribution-board cover to identify the cause yourself.
01
Describe the extent, not just the word “flicker”
Note whether one lamp, one room, several rooms or the whole property changed at the same time. Record whether sockets or other equipment were also affected. If nearby properties independently report the same interruption, include that information without treating it as proof of a network fault.
A controlled light, dimmer or recently changed lamp may be relevant to a single-fitting symptom. A wider pattern may need investigation of shared parts of the supply. The electrician should decide which possibilities the evidence supports, rather than applying the same repair to every situation.
02
Keep a brief event log
Write down when the change occurred, how long it lasted and what equipment was already operating. Include recent lighting changes, building work or electrical alterations. A safe, short video can show an intermittent symptom, but never approach sparking, damaged or exposed equipment to record it.
Do not switch large appliances repeatedly to trigger the problem. Existing observations are more useful than an unsafe experiment. If the pattern is uncertain, describe the uncertainty rather than filling in a likely sequence.
- The Discovery address and the exact rooms or fittings affected.
- Whether other equipment changed at the same time.
- The event time, duration and any recent alterations.
- Access arrangements for a shared board, cottage or occupied room.
03
Treat electrical warning signs seriously
Flickering accompanied by a burning smell, crackling, smoke, visible damage or unusual heat needs prompt attention. Do not touch a fitting to test its temperature. Keep clear and isolate only from a safe, accessible switch if doing so is safe; obtain emergency assistance for immediate danger.
Do not bypass a protective device or increase its rating to keep the lights on. If protection operates repeatedly, stop repeated resets and report the symptom. Electrical Safety First lists arcing sounds, burn marks and repeated protective-device operation among warning signs that should not be ignored.

04
What a useful investigation should establish
Ask the electrician to identify the affected part of the installation and explain the findings. Depending on the symptom, the assessment may distinguish equipment or controls from a circuit, connection or supply issue. A change that makes a light work temporarily does not by itself establish a complete repair.
If the suspected boundary involves a provider or shared building supply, agree the next reporting route and retain the findings. Access limitations should be recorded so that an uninspected part of the installation is not mistaken for one that has been cleared.
05
Plan repairs and any certification separately
Confirm the attendance scope and how further testing, materials or return visits will be handled. Keep the original event notes alongside the findings and completed-work records so a repeat occurrence can be compared accurately.
If an electrical COC in Discovery is also needed, mention it at the outset. A specific lighting investigation is not a whole-installation compliance assessment. The Department of Employment and Labour emphasises competent, legally registered contractors and actual inspection and testing for certification.

Arrange electrical help in Discovery
For electrical repairs, fault finding or an electrical compliance certificate in Discovery, use the area page to prepare your booking. Tell Wesslink the exact address, symptom or intended work and who can authorise access. Availability and the attendance scope are confirmed when you book.
The electrical price guides explain common cost factors; the client-review section helps you compare customer experience. A guide is not a fixed quotation for an unseen installation. Call 072 271 7111, WhatsApp Wesslink or email bookings@wesslink.co.za.
FAQ
Questions readers also ask
Does a new bulb rule out an installation problem?
No. A lamp change does not test the rest of the circuit or supply. Describe any remaining or recurring symptoms.
Is a video required to book fault finding?
No. Clear written observations are enough to start the conversation. Only record video if it can be done safely.
Does a flickering-light repair include a whole-property COC?
Not automatically. Confirm the fault-finding, repair and certification scopes before the appointment.
