South African households are increasingly feeling the financial strain as essential living costs continue to rise faster than overall inflation, placing significant pressure on already stretched budgets across the country.
Key Takeaways
- Electricity and water costs are rising far faster than inflation: Electricity prices increased by about 85% and water by 68% over five years, compared to roughly 30% general inflation.
- More increases are already on the way: Eskom’s 8.8% tariff hike and expected municipal increases of around 9% will place additional pressure on household budgets.
- Infrastructure and financial challenges are driving higher costs: Ageing infrastructure, maintenance backlogs, and operational pressures at Eskom and municipalities continue to push tariffs higher.

Utility Costs Surge as Electricity and Water Prices Outpace Inflation
The most recent Cost of Living report released by the Competition Commission highlights that the costs of basic utilities, particularly water and electricity, are increasing at a pace far exceeding headline inflation, leaving many households struggling to keep up with everyday expenses.
According to findings in the report, electricity price inflation in South Africa has risen dramatically, climbing by roughly 85% over the five-year period leading up to January 2026.
This steep increase stands in stark contrast to general consumer inflation, which rose by approximately 30% over the same timeframe.
The 85% increase in electricity costs includes the tariff adjustments implemented in July 2025 by municipalities across the country. Prior to these changes, cumulative electricity price increases from 2020 to June 2025 stood at approximately 68%, according to the Competition Commission.
However, these figures do not yet account for Eskom’s most recent price adjustments, which are expected to further compound financial pressure on consumers.
The report was published on the same day that Eskom implemented an 8.8% tariff increase for its direct customers. In addition, municipalities across South Africa are expected to introduce further electricity tariff increases of approximately 9% from July.
Water Costs Also Climbing Rapidly
The Competition Commission also noted that water supply costs have followed a similar upward trend, with water tariffs experiencing notable acceleration over recent years.
Following municipal tariff adjustments in 2025, water supply prices increased by 68% over the same five-year period.
Before the July 2025 adjustment, the cumulative increase in water prices between 2020 and June 2025 was around 50%, according to the report.
The commission further explained that these rising costs largely originate from government-controlled pricing structures, with state-owned entities such as Eskom and municipalities playing a major role in driving price increases.
Water and electricity are classified as regulated or administered prices in South Africa. However, the Competition Commission emphasised that regulated pricing does not automatically guarantee affordability for consumers.
The group noted that pricing is typically influenced by operational costs, infrastructure maintenance, capital investment requirements, and financial sustainability targets, with individual municipalities setting tariffs for end users.
These operational and financial pressures have increasingly shifted the burden onto households, making essential services progressively less affordable.
Eskom’s long-standing operational challenges have further intensified these pressures. Decades of underinvestment, governance challenges, corruption allegations, and infrastructure neglect have left the utility facing substantial cost increases and mounting financial obligations.
At the same time, municipalities across South Africa have experienced similar challenges, including:
- Ageing infrastructure
- Deferred maintenance
- Limited investment in upgrades
- Service delivery challenges
- Expanding demand from growing populations
These issues have contributed to the steady rise in utility tariffs as municipalities attempt to recover costs and fund operations.
Households that track monthly electricity usage and adjust consumption patterns during peak hours can often reduce bills by 5% to 15%, depending on tariff structures.
Rising Utility Costs Compared to General Inflation
The divergence between utility inflation and general inflation has become increasingly pronounced in recent years.
| Category | Increase Over 5 Years |
|---|---|
| Electricity | 85% |
| Water | 68% |
| General Inflation | 30% |
This widening gap highlights the growing financial burden placed on households, particularly those already managing rising food, fuel, and transport costs.
Electricity tariffs in South Africa have increased more than four times faster than inflation in some municipalities over the past decade.
The Problem Is Not Expected to Ease Soon
The Competition Commission warned that the upward pressure on water and electricity prices is unlikely to subside in the near future.
With the 8.8% Eskom tariff increase already implemented for 2026 and municipal increases of around 9% still scheduled for July, households are expected to face continued financial pressure.
The National Energy Regulator of South Africa, Nersa, has also approved further tariff increases for Eskom in 2027, allowing another 8.8% increase.
Additional tariff adjustments are also anticipated in Eskom’s upcoming Multi-Year Price Determination applications, with projections suggesting increases could exceed previous expectations.
These developments stem from an administrative error made by Nersa during the processing of Eskom’s latest tariff application, which resulted in an undercalculation of Eskom’s costs by approximately R54.7 billion.
To correct this error, Nersa approved a structured recovery plan allowing Eskom to recoup the shortfall from customers over several years.
The first portion of this recovery, amounting to R12 billion, will be collected through higher tariffs in 2026. This adjustment increased the planned tariff hike from 5.4% to 8.8%, effective from 1 April.
A further R23 billion will be recovered through tariff increases in 2027, pushing the planned increase from 6.2% to 8.8%.
The remaining R19.7 billion will be recovered through future tariff applications in subsequent years.
Long-Term Cost Pressure on Households
These developments indicate that South African consumers will likely face sustained electricity price increases over the coming years.
As a result, electricity costs are expected to continue diverging from general consumer price inflation, which the South African Reserve Bank aims to keep around 3%.
The growing gap between administered prices and general inflation highlights how essential services are becoming a major driver of cost-of-living increases.
This divergence reinforces the central role that utilities play in shaping household financial stability and long-term affordability.
The Competition Commission concluded that recent policy decisions and regulatory developments suggest that upward tariff pressure is unlikely to ease in the foreseeable future.
Many municipalities offer free basic electricity allocations for qualifying households. Checking eligibility may help reduce monthly expenses.
Utility costs now account for a significantly larger share of household budgets compared to a decade ago, particularly among middle-income earners.
What Households Can Do to Reduce Utility Costs
While price increases may continue, households can take proactive steps to manage rising utility expenses:
| Electricity Saving Tips | Water Saving Tips |
|---|---|
| Use energy-efficient lighting and appliances | Fix leaks immediately |
| Turn off standby devices | Install low-flow showerheads |
| Shift usage to off-peak hours where possible | Use greywater for gardens |
| Install solar or backup solutions if feasible | Reduce outdoor water usage |
A leaking tap can waste thousands of litres of water per year, significantly increasing household bills.
Conclusion
South African households are likely to remain under mounting financial pressure as electricity and water tariffs continue to rise faster than general inflation. With additional increases already approved and infrastructure challenges still unresolved, utility costs are expected to remain a key driver of the country’s cost-of-living crisis. As a result, households may need to adjust spending, improve energy efficiency, and plan for ongoing increases as essential services become progressively more expensive.
