How to Switch Electricity Plans Without Getting Stung

Switching electricity retailers is one of the few genuinely free ways to cut a power bill — but the market is built to make comparison hard. Headline discounts, shifting tariff structures and 'conditional' fine print can turn an apparently cheaper plan into a worse one. This guide walks through how to compare offers the way an independent engineer would: on what you'll actually pay, not what the ad shouts.

Start with your own usage, not the ad

The single most useful document is your most recent bill. Before you look at a single offer, pull out four numbers:

• Your total annual usage in kWh (add up a year of bills if you can — usage swings with the seasons).
• Your tariff type — flat (single rate), time-of-use (peak/shoulder/off-peak), or demand (charged on your highest 30-minute spike).
• Your daily supply charge (a fixed cost per day you pay regardless of usage).
• Your feed-in tariff, if you have solar — this varies widely and has trended down for years. Retailer-set in most states; VIC, regional QLD and TAS set a regulated minimum, so confirm the current rate for your state.

Without these, you're comparing marketing, not money. A plan with a low usage rate and a high daily supply charge can easily cost a light user more than a 'pricier' plan with a low fixed charge.

Read offers against the reference price, not each other

Retailers must state each plan's price as a percentage of a government benchmark (the Default Market Offer in most of the country, or the Victorian Default Offer in Victoria). That gives you one honest apples-to-apples lever.

An offer advertised as '15% below reference price' is cheaper for a typical user than one at '5% below' — provided the usage assumptions match yours. The catch: the reference figure assumes an 'average' household. If your usage is unusual (big solar export, electric hot water, a pool, or you're out all day), the percentage can mislead. Use it as a first filter, then model your actual kWh against the per-unit rates.

Discounts that aren't

Not all discounts are real savings. Watch for these:

• Conditional discounts — e.g. 'pay on time' or 'direct debit' discounts. Miss the condition once and you pay the full, higher rate. Ask what the rate is without the condition met.
• Discounts off an inflated base — a big percentage off a rate that was quietly set high is worth less than a small percentage off a genuinely low rate. The reference-price percentage cuts through this; a raw 'X% off' claim does not.
• Sign-up credits — a one-off bill credit is handy but it's a single-year sweetener. Divide it across the year and compare the ongoing rates, which is what you'll live with after the credit is gone.
• Bundled 'perks' — rewards points or subscriptions rarely beat a plan that's simply cheaper on energy.

Check the structure before you check the price

Switching can quietly change your tariff type, which matters more than a few cents on the rate. Things to confirm:

• Flat vs time-of-use. Time-of-use peak periods are commonly around 2–8pm (later in some states). If you can shift laundry, dishwashing and charging out of peak, a time-of-use plan can win; if you can't, it can sting you. Confirm the exact peak window from the plan — and from your own bill.
• Demand charges. Some plans add a charge based on your single highest usage spike. One simultaneous run of aircon, oven and pool pump can set that charge for the whole month.
• Smart meter requirements. Time-of-use, demand tariffs and newer offers generally need a smart meter. The federal Solar Sharer free-power window (live from 1 July 2026), which offers a free usage window of 11am–2pm capped at 24 kWh/day on eligible opt-in plans, requires a smart meter — and availability varies by retailer and state, so confirm it applies to you.
• Solar customers: check the feed-in tariff and any export limits, not just the import rate. A great usage rate with a poor feed-in tariff can be a net loss if you export a lot.

The fine print that costs real money

• Exit and early-termination fees — rarer than they were, but still exist on some fixed-benefit plans.
• Fixed-term vs variable rates — a fixed rate protects you from rises but can trap you above the market if prices fall. Know which you're signing.
• Benefit-period expiry — many discounts last 12 months, then the plan reverts to a higher rate unless you re-sign. Diarise the end date.
• Estimated vs actual billing and your cooling-off rights to unwind a switch.

Here's the honest catch

Chasing the absolute cheapest plan every year is a real time cost, and the savings on a modest bill can be smaller than the hours spent. For some households the sensible answer is to switch once to a genuinely competitive, low-reference-price plan with no conditions — then re-check annually rather than monthly. And if your usage pattern is awkward (heavy daytime, big solar export, demand-charged), the 'best' advertised plan for an average home may simply be wrong for you. The point isn't always to switch — it's to switch only when the maths, on your numbers, actually works.

We don't sell electricity, sign you to a retailer, or earn a referral cent when you switch. We model your real usage against the offers and tell you plainly whether moving saves you money — or whether you're already on a plan that's hard to beat.
