As the cost of living continues to rise across Gauteng, electricity remains one of the most significant monthly expenses for households in Ekurhuleni. With new Ekurhuleni electricity tariffs officially approved for the 2025/26 financial year, residents are looking for clear answers: How much will electricity cost, and how can I manage my usage without compromising comfort or safety?
The City of Ekurhuleni has published its updated tariff structure, offering residents transparency into the cost per kilowatt-hour (kWh) and how billing is calculated based on usage levels. This article breaks it all down — from understanding the Inclining Block Tariff (IBT) system to practical strategies for keeping your electricity bill in check.
Understanding the Ekurhuleni Electricity Tariff System
Like many metros in South Africa, Ekurhuleni uses an Inclining Block Tariff model for residential customers. This means the more electricity you consume, the higher the rate you’ll pay per unit. The system is designed to promote energy efficiency and ensure that lower-income households using minimal power are charged at a lower rate.
What Are Inclining Block Tariffs (IBT)?
Each month, your electricity usage is grouped into different “blocks”:
- Block 1: Covers essential usage and is the cheapest per unit.
- Block 2–4: Each successive block becomes more expensive, penalising high consumption.
The goal is to protect basic usage while encouraging households to avoid excessive electricity use — particularly important in a country facing energy supply challenges.

2025/26 Residential Tariff Breakdown
Here’s a look at the approved electricity tariffs in Ekurhuleni for the 2025/26 period. These rates apply mainly to prepaid residential customers, who represent the majority in the metro.
| Tariff Block | Usage Range | Approximate Rate | Who It Affects |
|---|---|---|---|
| Block 1 | 0–100 kWh | ± R1.50/kWh | Lower-income and low-usage households |
| Block 2 | 101–350 kWh | ± R2.20/kWh | Standard residential use |
| Block 3 | 351–600 kWh | ± R2.80/kWh | High-consumption homes |
| Block 4 | 600+ kWh | ± R3.20/kWh | Large households or those with energy-intensive usage |
These blocks reset each calendar month, so monitoring your usage regularly is key to avoiding higher blocks.
What These Tariffs Mean for Real Households
To make sense of these numbers, here are three practical examples based on common household consumption patterns:
Example 1: Small Household (±250 kWh/month)
- Mostly stays within Blocks 1 and 2
- Likely monthly cost: R450–R550
- Common among single-person flats, pensioners, or careful energy users
Example 2: Medium Household (±400 kWh/month)
- Spends time in Block 3
- Likely monthly cost: R900–R1,100
- Typical for families with children, appliances, and regular cooking
Example 3: Large Household (±650 kWh/month)
- Crosses into Block 4
- Likely monthly cost: R1,600–R2,000
- Found in homes with geysers, heaters, multiple TVs or computers
Key takeaway: Crossing the 350 kWh threshold significantly increases your cost per unit — making it the most important number to watch if you want to save.
Why Ekurhuleni Electricity Tariffs Matter Now More Than Ever
Electricity pricing is no longer just a budgeting issue — it’s a broader economic concern. As inflation squeezes household budgets, utility costs have become a major pressure point.
For Ekurhuleni residents, rising tariffs have a ripple effect:
- Less money for food and transport
- Immediate impact for prepaid customers
- High-density homes and backyard rooms push usage into higher blocks
- Load shedding recovery periods often spike consumption unexpectedly
Municipal officials acknowledge this delicate balancing act, needing to cover Eskom costs and infrastructure maintenance while keeping power affordable for residents.
Prepaid vs Postpaid: What’s Better for Budgeting?
In Ekurhuleni, the majority of households use prepaid electricity, and for good reason.
Prepaid Benefits
- Real-time usage awareness
- No surprise bills at month-end
- Easier to track and manage usage
Postpaid Risks
- Delayed visibility of consumption
- Higher fixed charges
- Risk of large, unexpected month-end bills
Unless you have very consistent and predictable usage patterns, prepaid remains the safer and more budget-friendly option, particularly for lower- and middle-income households.
Smart Ways to Keep Your Electricity Bill Down
Here’s how to take control of your energy usage and avoid slipping into the most expensive tariff blocks:
1. Stay Under 350 kWh
This is the most important usage cap. Do regular meter checks or track your prepaid token consumption to stay within affordable rates.
2. Control Your Geyser
Geysers are energy-hungry — responsible for up to 40% of your household usage. Use a timer or switch it off during the day to cut back.
3. Limit Heater Use in Winter
Portable heaters can send your usage soaring. Layer up and use blankets instead, or switch to a hot water bottle.
4. Cook Smarter
Batch cooking, using a microwave, or switching to gas can help reduce peak electricity use.
5. Track Your Prepaid Units
If your electricity is depleting faster than usual, it’s a warning sign that you’ve moved into a higher block.
Who’s Most Affected by Tariff Hikes?
Not all households feel electricity costs equally. The groups most vulnerable to higher bills include:
- Large families sharing a single meter
- Homes with backyard dwellings
- Work-from-home households using power all day
- Pensioners and elderly residents relying on electric heating
For these households, small changes in usage can mean big differences in monthly bills.
What the Future Holds for Ekurhuleni’s Electricity Prices
Electricity tariffs in Ekurhuleni are reviewed annually and often adjusted based on:
- Eskom’s bulk supply pricing
- Municipal infrastructure upgrades
- Changing consumption trends post load-shedding recovery
While no drastic structural changes are currently on the horizon, further incremental increases are expected, making energy literacy a long-term necessity.
Take Control of Your Power Spend
Electricity costs aren’t just about what you pay per unit — they’re about your habits, appliances, and lifestyle.
By understanding the Ekurhuleni electricity tariff system, tracking your usage, and adopting energy-saving practices, you can reduce your electricity spend without sacrificing comfort or safety.
