How to Save Electricity in South Africa: 9 Practical Ways to Lower Your Bill
You’ve seen the news. From April 2026, Eskom direct customers face an 8.76% tariff increase, while municipal customers will see an average 9.01% increase from 1 July 2026. That makes everyday electricity habits more important than ever. This guide walks you through 9 electricity-saving tips that actually work in South African homes, from quick wins to bigger changes. No jargon, no extreme lifestyle overhaul. Just practical steps you can start using today.
1. Switch to LED Lighting
If you haven’t already swapped your old bulbs, now is the time. LED bulbs use up to around 85% less energy than incandescent or halogen bulbs, and they usually last much longer too.
Start with the five to ten bulbs you use most often: kitchen, living room, passage, and outdoor security lights.
Look for warm-white LEDs (2700K to 3000K) for a cosy feel. No more harsh, blue-toned light.
2. Kill Standby Power
Your TV, decoder, computer, microwave clock and phone chargers can still draw power when they look “off.” This standby power may seem small on its own, but it can add up across several devices in the home.
The fix is simple: turn appliances off at the wall plug.
For hard-to-reach outlets, use a power strip with a switch. Keep your fridge and freezer running, but switch off TVs, chargers, gaming consoles, computers and small appliances when they do not need power.
3. Tame Your Geyser
Here’s a fact that might surprise you. Water heating accounts for around 30% to 50% of the average South African household’s electricity bill and more than your lights, fridge, TV, and computer combined. And most geysers run 24/7, heating water when nobody is actually using it.
A geyser timer is one of the most practical fixes. Set the timer to heat water before morning showers—keeping in mind how long a geyser takes to heat up to your desired temperature—and again before evening dishes or baths. You can usually turn it off overnight and during long periods when nobody is at home.
For better results, insulate your geyser and the first few metres of hot water pipes with foam sleeves. This helps the water stay hot for longer, so the geyser does not need to work as often.
4. Master Your Kitchen Habits
Your kitchen is full of energy-hungry appliances, but small changes add up fast:
The kettle rule: Only boil the amount you need. A full kettle uses nearly twice the energy of a half-full one because it takes significantly longer to heat more water. Because a standard kettle is high-wattage, boiling only what you need is one of the easiest ways to cut daily energy waste.
Fridge efficiency: Set your fridge between 2°C and 5°C, and your freezer to -15°C to -18°C. Check the door seal. If a piece of paper pulls out easily when the door is closed, the seal needs replacing.
Dishwasher discipline: Always run a full load, and use the eco mode if your machine has one.
Cooking efficiency: Use lids on pots whenever possible and match pot size to the stove plate. Pressure cookers or air fryers can also reduce cooking time and energy use.
During outages or periods of high electricity demand, a portable power station can also help keep essential kitchen appliances running. The EcoFlow DELTA 3 Max Portable Power Station delivers enough output for refrigerators, microwaves, and other everyday appliances, helping households maintain normal routines while using stored solar energy more efficiently.
5. Wash, Dry and Iron More Efficiently
A tumble dryer is one of the more power-hungry appliances in the home, especially when it runs often or for small loads. South Africa gets sunshine for much of the year, so a clothesline or folding drying rack is usually the cheaper option whenever the weather allows.
When you do use the dryer, run fuller loads where possible and clean the lint filter every time. This helps the machine work more efficiently and also reduces the fire risk.
If you iron regularly, avoid switching the iron on for one or two items at a time. Iron clothes in batches, start with lower-heat fabrics, then move to heavier cotton items once the iron is fully hot. This reduces repeated heating and makes better use of the electricity already used.
6. Schedule Heavy Loads Around Your Tariff
Load shifting simply means running heavy appliances, such as the dishwasher, washing machine, pool pump and geyser, at times that make sense for your tariff and daily routine.
Check your latest bill first. Some households pay a flat rate for electricity, while others may have peak and off-peak periods.
If your tariff changes by time of day, try to avoid running heavy loads during expensive evening peak times.
If your tariff charges the same rate all day, focus more on reducing unnecessary running time.
For pool pumps, this matters even more. Many pools do not need the pump running all day, especially outside the hottest months. Check what your pool size, pump type and water condition actually need, then adjust the schedule gradually.
Homes with solar panels and battery storage can take load shifting even further. By charging a battery during sunny periods or lower-cost electricity hours and using that stored energy later, households can reduce dependence on expensive peak-time grid electricity. The EcoFlow RIVER 3 UPS Solar Generator (110W Lightweight Solar Panel) supports smart app-based monitoring and energy management, making it easier to optimise electricity usage around changing tariffs and household demand.
7. Insulate Your Home
The more heat your home loses, the more electricity your heater (or air conditioner) has to use to keep you comfortable.
You don’t need a full renovation to make a difference. For renters and homeowners on a budget:
Add weather stripping around loose window frames.
Attach a draught excluder to the bottom of external doors.
Hang thermal curtains or blinds.
For homeowners, ceiling insulation is one of the best long-term investments you can make.
8. Replace Old, Inefficient Appliances
Older appliances can quietly use more electricity than newer, more efficient models, especially fridges, freezers, washing machines and dishwashers that run often.
When an appliance finally gives up, check the South African Energy Efficiency Label before buying a replacement. Compare the estimated energy use rather than just looking at the letter rating, because two similar-looking appliances can draw very different amounts of power over time.
Don’t rush to replace a perfectly good appliance just for the energy savings. Use it well, keep it clean and service it when needed. Then, when it is time to replace it, choose the most efficient model that fits your home, budget and daily use.
9. Do a Quick Home Electricity Audit
A quick DIY energy audit helps you pinpoint exactly where your electricity goes each day. Finding these specific high-use areas allows you to stop unnecessary power wastage immediately and lower your next bill.
Check your meter at the same time every day. If you use a prepaid system, ensure you register your prepaid meter correctly to track usage accurately and avoid tariff errors from day one.
Check your bill for units used, not just the random amount.
Walk through each room and list appliances that stay on for hours.
Use a plug-in energy meter for anything you suspect uses too much power.
Compare weekday and weekend use, especially if someone works from home.
Conclusion
The electricity tariff hikes are real, but you don’t have to accept a higher bill every month. Start with simple steps this weekend: install a geyser timer, switch to LED bulbs, turn off appliances at the wall, and air-dry laundry. Small actions, done consistently, add up to meaningful savings. For households looking to go further, a portable power station can help reduce grid reliance and keep essential devices running during outages or peak pricing. The cheapest kilowatt-hour is the one you never use.
FAQs
What uses the most electricity in a house?
In a typical South African home, the geyser is the single biggest electricity user – it accounts for 30% to 50% of your monthly bill. That’s more than your lights, fridge, TV, and computer combined. Space heating (heaters, electric blankets, air conditioners) comes second, followed by kitchen appliances. If you want the biggest impact with the least effort, focus on your geyser: install a timer, insulate the tank and pipes, and consider a solar water heater or heat pump for long-term savings.
What is the cheapest way to pay for electricity?
The cheapest way to pay for electricity in South Africa depends on your municipality, tariff, and monthly usage. Prepaid electricity helps many households manage spending and track usage, but it is not always the cheapest option. Before choosing prepaid or postpaid, check for fixed monthly charges and other tariff fees. If you use prepaid, buy through a low-fee or fee-free channel where possible. Some digital services, including Prepaid24’s WhatsApp option, offer zero service fees with certain payment methods, so it is worth comparing how many kWh you receive for the amount paid.
How much electricity do I get for R500 per month?
The number of units you get for R500 depends on your tariff, municipality, VAT, fixed charges and whether your account uses prepaid or postpaid billing. As a rough way to estimate it, divide R500 by the per-kWh rate shown on your bill. For example, if your effective rate is around R3 per kWh, R500 would buy roughly 160 kWh before any fixed or service charges.
