10 Practical Ways to Reduce Your Eskom Bill

Start with the geyser

1. Fit a geyser timer or blanket

Your electric geyser can account for a huge share of household consumption because it reheats water around the clock, even while you sleep. A simple timer that runs it only before you need hot water, paired with an insulating geyser blanket and lagged pipes, cuts wasted reheating. It is one of the cheapest interventions with one of the fastest paybacks.

2. Turn the thermostat down

Many geysers are set hotter than anyone needs, then the hot water is mixed back with cold at the tap. Dropping the thermostat to a sensible setting reduces standing heat loss without leaving you short of hot water. It costs nothing and takes minutes.

Attack the everyday waste

3. Switch to LED lighting throughout

If you still have any halogen or incandescent bulbs, replacing them with LEDs cuts lighting energy dramatically for the same brightness. LEDs also last far longer, so you save on replacements too. It is a small upfront spend that quietly keeps paying.

4. Kill standby power

Devices left on standby — TVs, decoders, chargers, the microwave clock, gaming consoles — sip power continuously. Switching them off at the wall, or grouping them on a single switched plug strip, removes a load that runs 24 hours a day for zero benefit.

5. Use appliances smartly

Run the washing machine and dishwasher with full loads, wash clothes in cold water where you can, and keep the fridge and freezer well sealed and not overfilled with warm items. None of these are dramatic on their own, but together they shave a steady percentage off every month.

Get the big appliances right

6. Rethink heating and cooling

Space heating and air-conditioning are power-hungry. Sealing draughts, closing curtains at night to hold heat, and using a heater only in the room you occupy all reduce the load. If you are replacing an air-conditioner, an efficient inverter model uses far less than an older unit for the same comfort.

7. Choose efficient replacements

When any major appliance dies, treat the replacement as an efficiency decision, not just a price decision. A more efficient fridge, geyser or aircon costs a little more upfront and then saves every single day for a decade. Over the appliance's life, the running cost dwarfs the purchase price.

Understand and outsmart your tariff

8. Read your bill and know your tariff

You cannot manage what you do not understand. Many households have no idea whether they are on a flat rate, a stepped (inclining block) tariff, or a time-of-use structure. If you are on a stepped tariff, pushing your total consumption into a lower block by cutting waste saves disproportionately. If you are on time-of-use, shifting heavy loads like the geyser and washing away from peak periods directly lowers the bill.

9. Consider prepaid discipline

For some households, a prepaid meter makes consumption visible and immediate in a way a monthly account never does. Watching the units tick down tends to sharpen everyone's habits, and that behavioural nudge alone can trim usage. It will not suit everyone, but the visibility is a genuine tool.

Generate your own power

10. Go solar with a battery

Every step above chips away at the bill. Solar is the one that changes its shape entirely. By generating your own electricity during the day and storing it in a battery for the evening and load-shedding, you replace a large, rising Eskom charge with a smaller, more predictable one — and you get the bonus of staying powered when the grid goes down.

The entry point is far lower than most people assume. A starter system like Alumo's Bronze package (a Sunsynk 3.6kW inverter, a 3.6kWh battery and four panels) starts from around R1,911/month on a rent-to-own basis, and a no-deposit subscription starts from around R1,299/month. For many households, the monthly saving on the Eskom bill offsets a large part of that figure from the outset.

The right size depends on your actual usage, which is exactly what a proper assessment works out. Get a free quote → to see how much of your current bill a well-sized system could replace.

Putting it together

The smart approach is layered. Start with the free and cheap wins (the geyser timer, LEDs, killing standby, understanding your tariff) because they cost little and stack up. Then, once you've squeezed the easy savings, look at solar as the structural fix that caps your exposure to Eskom's next increase and the next round of load-shedding.

You do not have to do everything at once. Even the first three or four steps will show up on your next bill. And when you are ready for the big lever, the numbers are more accessible than they have ever been. Get a free quote → and you can see exactly where solar fits into your plan.

Frequently asked questions

What uses the most electricity in a South African home?

For most households the electric geyser is the single largest consumer, followed by heating and cooling. That is why a geyser timer, a geyser blanket and a sensible thermostat setting are usually the highest-impact low-cost changes you can make.

How much can I save without buying anything?

It varies by household, but behaviour changes and cheap fixes — geyser timing, LEDs, killing standby, running full appliance loads and shifting usage off peak — can trim a meaningful portion of your bill for very little or no cost. The exact figure depends on your current habits and tariff.

What is a stepped or time-of-use tariff?

A stepped (inclining block) tariff charges more per unit as your monthly consumption rises, so cutting waste can drop you into a cheaper block. A time-of-use tariff charges more during peak periods, so shifting heavy loads like the geyser to off-peak times lowers your bill. Check which one applies to you.

Is solar really worth it if I already save electricity carefully?

Often yes. Efficiency reduces the bill, but solar changes its structure by replacing rising Eskom charges with self-generated power. The two work together: a more efficient home needs a smaller, cheaper solar system to cover its needs.

How do I know what size solar system I need?

A proper site assessment looks at your actual consumption, roof and load-shedding exposure to size the system correctly.
