Why Your Electricity Bill Keeps Rising And Why Gas Is the Smarter Fix
If you’ve been switching off lights, running appliances at night and watching your kilowatt-hour consumption carefully — only to open a bill that’s higher than last month — you’re not alone. Across KwaZulu-Natal, households are experiencing the same frustrating reality: using less electricity no longer means paying less for it.
A June 2026 Light Paper published by residential solar provider GoSolr has put hard numbers to what South African families have quietly suspected for years. The country’s energy challenge has shifted. Load shedding has faded from the headlines, but a new crisis has taken its place: a structural affordability problem baked into the very way electricity is priced.
For homeowners in Durban, Umhlanga, Ballito and across KZN, there is a straightforward, proven response to this problem. LPG gas removes the most expensive electricity demands from your home entirely — and it does so at a fraction of the cost.
The problem with your electricity bill in 2026
South Africa’s electricity crisis used to be about supply — rolling blackouts, diesel generators and load shedding schedules pinned to every fridge in the country. That chapter has largely closed. But the financial damage from the Eskom era is still unfolding, and in some ways the new chapter is harder to fight back against.
The GoSolr Light Paper documents a trend that will be familiar to anyone who has studied their municipal account closely. Fixed connection charges — fees you pay simply to remain connected to the grid regardless of consumption — have grown dramatically. In some South African municipalities, these charges now exceed R1 700 per month before a single unit of electricity is consumed.
⚡ What this means for your household
Even if you install solar panels, buy a heat pump and replace every bulb with LED lighting, a large fixed fee on your account means your electricity bill will remain high. The tariff structure is designed to recover infrastructure costs regardless of how efficiently you behave. Efficiency alone is no longer enough.
On top of fixed charges, consumption tariffs themselves have continued climbing. Eskom implemented a 8.76% increase at the start of 2026, followed by a further 8.83% increase in April. Municipal customers in places like eThekwini often face additional mark-ups on top of the Eskom wholesale rate, pushing real-world costs even higher.
The GoSolr paper also points to what it calls “invisible costs” — the expenses that never appear on your bill but are very real nonetheless. Damaged appliances caused by voltage fluctuations. Productivity lost during outages. Security systems that need battery backups. Private generators and inverter setups that require maintenance. When you add these up, the true cost of electricity dependence is substantially higher than the number at the bottom of your monthly account.
Why switching to gas changes the equation entirely
LPG gas and electricity are not competing products in the same category — they are fundamentally different energy sources with different cost structures, different risk profiles and different reliability characteristics. Understanding the distinction is key to making a smart financial decision for your home.
Electricity is priced through a combination of variable tariffs and fixed charges, controlled by regulators and municipalities, and subject to annual increases that have consistently outstripped inflation for nearly two decades. Gas is priced as a commodity: you pay for what you buy, when you buy it, from a competitive market.
"Stability without affordability is not success — it's just a different kind of failure."
GoSolr CEO Andrew Middleton, June 2026For KZN homeowners, the two highest electricity demands in a typical household are water heating and cooking. A standard electric geyser running on South African tariffs is expensive to operate and an easy target for cuts during load shedding. An electric stove or hob draws significant load and contributes meaningfully to your monthly bill.
Both of these can be replaced with LPG gas — and when they are, the savings are immediate and sustained.
The numbers behind the switch
A gas geyser of equivalent capacity to a 150-litre electric geyser costs significantly less to run per litre of heated water. Gas delivers heat on demand — it heats precisely when you need it and stops the moment you don’t. Electric geysers, by contrast, maintain a reservoir of hot water at temperature continuously, consuming electricity around the clock even at 2am when nobody is showering.
Gas stoves and hobs offer immediate, controllable heat with no wasted energy from warming up a ceramic element or waiting for induction to respond. Professional chefs have always known this — and now it’s a financial advantage for South African homeowners too.
Gas vs electricity for key home applications
| Factor | Grid Electricity | LPG Gas |
|---|---|---|
| Monthly cost trend | Rising steeply +8.76% in 2026 | Stable & competitive commodity pricing |
| Fixed charges | Up to R1 700/month regardless of use | Zero — pay only for what you use |
| Load shedding impact | Full disruption without backup | Zero impact — fully grid-independent |
| Water heating efficiency | Stores heat continuously, losing energy overnight | Instantaneous — heats only on demand |
| Cooking performance | Delayed response, residual heat waste | Instant control — precise, responsive flame |
| Installation requirement | Existing wiring | SAQCC-certified installer + COC |
| Tariff structure transparency | Complex with hidden fixed fees | Simple — per-unit commodity price |
What the tariff data tells us about long-term energy planning
The GoSolr Light Paper’s most striking finding is historical context. South African electricity tariffs have risen by more than 1 100% since 2007. A household consuming 800kWh per month paid approximately R1 055 in 2014. By 2024, that same consumption cost approximately R3 388 — a 221% increase in just ten years.
There is no credible projection that suggests this trend will reverse. Eskom still carries significant debt. Municipal electricity distribution networks require ongoing capital investment. The funding model for South Africa’s electricity infrastructure is built on tariff revenue, and that means continued increases for the foreseeable future.
Planning your home energy strategy around electricity prices staying flat or falling is, at this point, a financial risk. Planning around an energy source that removes your dependence on grid electricity for your highest-consumption applications is prudent household economics.
✓ The gas advantage over time
Unlike electricity tariffs — which are set by regulators and municipalities and increase annually — LPG gas is a traded commodity. Its price is influenced by global markets and local competition between distributors. Historically, gas pricing in South Africa has been far more stable relative to electricity on a per-unit-of-energy basis, and the absence of fixed connection fees means every rand spent on gas delivers actual energy.
The five biggest benefits of switching to LPG gas in KZN
A gas geyser operates completely independently of the electricity grid. Load shedding, tripped breakers and grid faults have zero impact on your hot water supply.
Households that switch their geyser and stove to gas typically save up to 30% on monthly energy costs compared to running equivalent electric appliances on current Eskom-linked tariffs.
Gas flame responds immediately. You can reduce heat to a simmer in seconds or go from zero to full heat instantly — something electric hobs cannot replicate.
Gas has no standing charge or connection fee. You pay only for the gas you buy. This contrasts directly with electricity's growing fixed tariff component.
Gas geysers and gas stoves are sought-after features in KZN rental and resale markets. A SANS-compliant gas installation adds tangible value to your property.

Frequently asked questions
Why is my electricity bill going up even though I am using less electricity?
South African municipalities and Eskom now charge substantial fixed connection fees every month regardless of how much electricity you actually use. In some municipalities these fixed charges exceed R1 700 per month before a single unit is consumed. As a result, cutting your consumption no longer translates into proportional savings on your total bill — the fixed component remains regardless.
How much have electricity tariffs increased in South Africa since 2007?
According to the GoSolr Light Paper published in June 2026, South African electricity tariffs have increased by more than 1 100% since 2007. A household consuming 800kWh per month paid approximately R1 055 in 2014; by 2024 the same consumption cost around R3 388. Eskom implemented a further 8.76% increase and an additional 8.83% increase in April 2026.
Is gas cheaper than electricity in South Africa in 2026?
For the two highest-demand home applications — water heating and cooking — LPG gas is significantly more cost-effective than grid electricity at current tariff levels. Gas has no fixed connection charges, heats on demand rather than continuously, and its commodity pricing is more stable than the regulated annual increases applied to electricity tariffs. Most KZN households switching their geyser and stove to gas reduce monthly energy costs by 20–30%.
Does a gas geyser work during load shedding?
Yes. LPG gas geysers operate entirely independently of the electricity grid. They continue delivering hot water throughout any power outage or load shedding event, with no inverter, battery or backup system required. This makes them an immediately practical solution for South African homes regardless of whether load shedding returns.
How long does a gas geyser or gas stove installation take in Durban?
A standard gas geyser or gas stove installation by Alternate Energy Solutions typically takes between 2 and 6 hours depending on the complexity of the pipe run, the appliances being installed and site conditions. Most residential installations are completed within a single day. The process includes pipe installation, pressure testing, leak detection and the issuance of a Certificate of Conformity (COC).
What is a Gas Certificate of Conformity (COC) and do I need one?
A Gas COC is a legal document issued by a SAQCC-registered gas installer certifying that a gas installation complies with SANS 10087-1 regulations. It is required by law for any fixed LPG gas installation and is typically requested by insurers and is mandatory when selling a property. All Alternate Energy Solutions installations include a COC as standard. For standalone inspections of existing installations, a COC typically costs between R600 and R1 200.
