The 5 electricity plan traps that cost Australians $340 a year — and how to avoid them

Most Australian households are on the wrong electricity plan. Not because they made a bad choice — but because they accepted what they were offered at sign-up and forgot about it. Energy retailers rely on this inertia. Their best rates are never advertised to existing customers, and prices quietly drift upward through "conditional discount" expiry, standing-offer rollovers, and rate card changes buried in fine print.

After analysing billing data from thousands of Jerico households, we've identified five specific traps that together account for an average of $340 per year in avoidable spending.

Trap 1: The conditional discount cliff

Retailers advertise big headline discounts — "25% off your usage charges!" — but bury a critical condition in the fine print: the discount only applies if you pay on time, paperlessly, and sometimes only for the first 12 months. Miss a payment date by a single day and the discount evaporates for that bill cycle. Many customers don't realise this has happened until they've paid the non-discounted rate for six months.

"We found one customer who'd lost their conditional discount eight months earlier — they hadn't noticed an extra $48 per bill until Jerico flagged the change."

What to look for: compare your "pay-on-time discount" rate with what you actually paid in the last two bills. If they differ, check the conditions.

Trap 2: The standing offer rollover

When a market offer contract expires — usually after 12 or 24 months — retailers roll customers onto the standing offer rate unless the customer actively re-contracts. Standing offers are regulated but designed as a safety net, not a competitive product. In practice, standing offer rates run 15–30% higher than the best available market offers in your area.

Trap 3: The solar feed-in mismatch

If you have rooftop solar, your feed-in tariff varies significantly between retailers. At the time of writing, rates in New South Wales range from 1.2c/kWh to 8.5c/kWh. For a typical 6.6kW system exporting around 1,800 kWh per year, that's a difference of roughly $131 per year for doing nothing different.

Trap 4: Peak/off-peak plan mismatch

Time-of-use plans can save money if usage patterns align — but they can cost more if they don't. We see many households on time-of-use plans whose actual consumption runs heavily in peak periods (typically 2–8pm weekdays). For these households, a flat-rate plan would be materially cheaper.

Trap 5: The introductory rate expiry

Some retailers offer below-market introductory rates for 3–6 months to win new customers. These revert to standard pricing — sometimes without meaningful notification. A low intro rate might save $40 in the first three months, but if you don't re-shop at expiry, you could pay an above-market rate for years afterwards.

What to do next

Check your electricity plan every 12 months. The government comparison tools are free and unbiased. Switching retailer is a straightforward online process that takes under ten minutes and requires no physical work or technician visit.

Jerico automates this: it tracks your billing data, benchmarks your rate against current market offers, and notifies you when a materially better deal is available. Users on the Household plan have saved an average of $318 in their first year on electricity alone.
