Managing prepaid electricity can be challenging, especially as electricity prices continue to put pressure on household budgets. Running out of units before your next top-up can be frustrating, but small changes in how you use electricity can make a noticeable difference over time.
In this guide, you’ll learn practical ways to reduce electricity consumption, identify the appliances that use the most power and make your prepaid electricity last longer without sacrificing everyday comfort.
How does prepaid electricity work?
With a prepaid electricity meter, you buy electricity units before using them instead of receiving a bill afterward.
Each time electricity is used, the meter deducts units from your available balance. Once the balance reaches zero, the supply is automatically disconnected until more credit is loaded.
Many households in South Africa use prepaid meters because they make it easier to monitor electricity use and manage monthly spending. Eskom also notes that prepaid meters help customers keep track of their remaining credit and better control their consumption.
Which appliances use the most electricity?
One of the easiest ways to stretch your prepaid electricity is to identify the biggest energy users in your home.
Although every household is different, these appliances are often responsible for the highest electricity consumption:
- electric geysers;
- space heaters;
- electric stoves and ovens;
- tumble dryers;
- kettles;
- air conditioners.
According to Eskom, geysers alone can account for a significant share of a typical household’s electricity use, making them one of the best places to start when trying to reduce consumption.
Simple ways to make prepaid electricity last longer
Reducing electricity use doesn’t always require expensive upgrades.
Small daily habits can add up to noticeable savings over the course of a month.
Some of the most effective tips include:
- switch off lights when leaving a room;
- boil only the amount of water you need in the kettle;
- unplug appliances that are not being used;
- use natural daylight whenever possible;
- wash clothes with cold water when appropriate;
- allow food to cool before placing it in the refrigerator.
These habits not only reduce electricity use but also help you make your prepaid electricity last longer between purchases.
Pay special attention to your geyser
If your home has an electric geyser, it is one of the best places to focus your energy-saving efforts.
Eskom recommends avoiding unnecessary heating because water heating is one of the largest contributors to residential electricity consumption.
You can often reduce consumption by:
- taking shorter showers;
- lowering the geyser thermostat to a safe, efficient setting;
- fixing leaking hot-water taps;
- insulating the geyser and exposed hot-water pipes where practical;
- turning the geyser off during long periods when nobody is home, if appropriate for your household.
Should you switch appliances off instead of leaving them on standby?
Yes, whenever possible. Many electronic devices continue using small amounts of electricity even when they appear to be turned off. This is often called standby power or phantom load.
While the amount used by a single appliance may seem small, the combined effect of multiple devices left on standby every day can increase overall electricity consumption.
Examples include:
- televisions;
- decoders;
- gaming consoles;
- desktop computers;
- microwave ovens with digital displays;
- chargers left plugged into wall sockets.
Switching these appliances off at the plug when they are not needed can help reduce unnecessary energy use.
Does using electricity at certain times make a difference?
For most residential prepaid customers, the number of units used matters more than the time of day they are consumed.
However, some municipalities and electricity providers offer prepaid tariffs with different pricing structures, including time-of-use tariffs for certain customers.
If you’re unsure which tariff applies to your property, check with your municipality or electricity provider. Understanding your tariff can help you plan energy-intensive tasks more efficiently.
How can you monitor your electricity usage?
One of the biggest advantages of prepaid electricity is that it allows you to see how quickly your available units are being used.
Instead of waiting for a monthly bill, you can monitor your balance regularly and identify changes in your household’s electricity consumption.
It may also help to:
- record how long each electricity purchase lasts;
- compare usage before and after changing household habits;
- keep an eye on seasonal changes, as winter often increases electricity demand due to heating needs.
Tracking your consumption makes it easier to spot patterns and adjust your usage before your credit runs out.
Small changes can lead to noticeable savings
Making prepaid electricity last longer doesn’t always require major investments or lifestyle changes. In many homes, a combination of simple habits, regular monitoring and smarter use of high-consumption appliances can noticeably reduce electricity usage over time.
By understanding where most of your electricity is going and making small adjustments where possible, you can stretch each top-up further while keeping your household running efficiently.

Frequently Asked Questions
Does buying more prepaid electricity at once make it last longer?
No. Buying more units doesn’t reduce your electricity consumption. How long your credit lasts depends on how much electricity your household uses.
Can unplugging appliances really save electricity?
Yes. Some appliances continue drawing small amounts of electricity while on standby. Unplugging devices that aren’t being used can help reduce unnecessary consumption.
Why does my prepaid electricity seem to run out faster in winter?
Many households use more electricity during colder months because geysers, heaters and electric blankets are used more frequently, increasing overall consumption.
How can I check my remaining prepaid electricity balance?
The method depends on your meter and electricity provider. Many prepaid meters display the remaining units directly on the device, while some municipalities and providers also offer online or mobile services.
Is prepaid electricity cheaper than billed electricity?
Not necessarily. The cost depends on the tariff set by your municipality or electricity provider. The main advantage of prepaid electricity is that it gives consumers more control over their usage and spending.
