Main information
What it could mean
Unstable power (flickering lights, appliances restarting, or voltage fluctuations) can come from a loose connection, a switchboard issue, or in some cases the supply network itself.
Safety first
If it coincides with a specific appliance being used, note it; that helps rule out whether the source is the installation or the appliance itself.
Next step
It's worth checking the switchboard and main connections to rule out an internal fault before assuming it's an issue with the supplier.
Frequently asked questions
Could this be a supplier issue rather than mine?
Possible; you can compare whether it also affects neighbours in the same building to rule it out.
Can a loose connection cause these fluctuations?
Yes, it's one of the most common causes within the installation itself.
Is it dangerous for appliances?
Sustained fluctuations can damage sensitive electronics; worth resolving as soon as possible.
