If you’re trying to understand household electricity usage in South Africa to budget, compare with other countries, or plan energy-saving upgrades, here’s a clear breakdown.
The average South African household uses:
~350–550 kWh per month
(depending on household size, appliances, and lifestyle)
This is 2–3× higher than Kenya, largely because South Africans rely more on electric cooking, heating, and water heating (geysers).
Electricity Use by Household Type
| Household Type | Monthly kWh | Typical Household |
|---|---|---|
| Low usage | 150–300 kWh | Small homes or apartments, limited appliances |
| Medium usage (most common) | 350–550 kWh | Typical family with fridge, cooker, geyser |
| High usage | 600–1,200 kWh+ | Large homes, pools, multiple appliances, electric heating |
For budgeting, 400–500 kWh/month is a safe middle estimate for a family home.
Monthly Electricity Cost (Estimate)
| Usage Level | kWh/month | Approx Cost (ZAR) | Notes |
|---|---|---|---|
| Low | 200 kWh | R450 – R600 | Small apartment |
| Medium | 450 kWh | R1,100 – R1,500 | Typical household |
| High | 900 kWh | R2,300 – R3,000 | Large home with big appliances |
Costs vary based on municipality, prepaid vs postpaid, and tariff structures.
Comparison: South Africa vs Kenya vs Global
| Country | Avg Monthly Household Use |
|---|---|
| 🇿🇦 South Africa | 350–550 kWh |
| 🇰🇪 Kenya | 120–200 kWh |
| Global average | 250–900 kWh |
| 🇺🇸 USA | 900–1,000 kWh |
Why SA is higher than Kenya:
- Electric stoves are common
- Electric geysers for hot water
- Higher electrification rate
- Larger average homes/appliance use
- Winter heating load in some regions

What Drives Electricity Use in Homes?
Major consumption areas:
- Electric geyser (hot water)
- Cooking (especially electric stoves/ovens)
- Refrigeration
- Heating/cooling
- Laundry appliances
- Pool pumps in high-income homes
Lifestyle factors:
- Number of occupants
- Time spent at home (work-from-home increases usage)
- Type of cooking and heating appliances
Typical Appliance Usage Per Month
| Appliance | kWh/month | Notes |
|---|---|---|
| Fridge | 30–60 | Always on |
| Electric stove/oven | 40–90 | Heavy use |
| Iron | 10–25 | Common in African homes |
| Electric geyser | 150–300 | Biggest power consumer |
| Washing machine | 10–20 | Varies by frequency |
| TV + router | 15–30 | Small but constant |
| Lighting (LED) | 10–25 | Higher with older bulbs |
Geyser = #1 electricity cost driver in most SA households.
How to Reduce Power Bills
Biggest wins first:
Install a geyser timer or switch to solar water heating
Use gas cooking or air fryer instead of oven
Switch to LED bulbs
Turn off standby appliances via smart plug
Use prepaid meter to track usage
Iron clothes in batches (reduces reheating cycles
