How to Switch Electricity Plans Without Getting Stung

Switching electricity retailers can genuinely save you money — but the market is designed to make that hard to prove. Big percentage discounts, headline rates and 'welcome' credits are all engineered to look good on an ad and mean little on your actual bill. The good news: you don't need to be an energy nerd to compare offers properly. You just need to know which numbers matter and which are noise. Here's how to switch without getting stung.

Compare the total annual cost, not the discount

The single most important rule: ignore the discount percentage and compare the estimated total annual cost for a household like yours. A '30% off' plan can easily cost more than a plan with no discount at all, because the discount is applied to an inflated reference rate. Discounts also come in flavours that matter:

• Pay-on-time / direct-debit discounts — you lose them the moment a payment is late. If your income is lumpy, treat the un-discounted rate as your real rate.
• Conditional vs unconditional — an unconditional discount applies no matter what; a conditional one has strings.
• Discount off usage vs off the whole bill — 'off usage only' skips the daily supply charge, so it's worth less than it sounds.

The Australian Government's free comparison site, Energy Made Easy (energymadeeasy.gov.au), lets you plug in your postcode or upload a bill and ranks plans by estimated annual cost. Victorians have their own equivalent, Victorian Energy Compare. Use these before any retailer's own calculator.

The three numbers that actually decide your bill

Every plan boils down to a handful of figures. Pull your latest bill and check these against any new offer:

• Supply charge (c/day) — a fixed daily cost you pay even if you use nothing. Over a year this adds up fast, and a low usage rate can hide a high supply charge.
• Usage rate (c/kWh) — what you pay per unit. On a time-of-use plan there are several: peak, shoulder and off-peak. Peak is typically around 2–8pm (later in some states) — confirm the exact window from your own bill.
• Feed-in tariff (c/kWh) — if you have solar, what you're paid for exports. These are retailer-set in most states and have trended down for years, commonly landing somewhere in the 3–10 c/kWh range. Victoria, regional Queensland and Tasmania set a regulated minimum. A big feed-in headline is often paired with worse usage rates — check both together.

Here's the catch: the offer can change after you sign

This is where people get stung. Most market contracts let the retailer change your rates with notice — the sharp price you signed up for can drift up after the benefit period ends (often 12 months). A few things to guard against:

• Benefit periods that expire. When the intro deal ends you may roll onto a worse rate. Set a calendar reminder to re-compare around that date.
• Exit or early-termination fees. Standard market contracts usually don't have them, but some 'special' deals do. Check before signing.
• Sign-up credits. A one-off $100–$200 credit is nice, but a plan that's $150/year cheaper on the underlying rates beats it every year after the first.
• Bundled 'perks' — subscriptions, rewards points, referral bonuses. Value them at close to zero and compare the raw energy cost.

Switching itself is low-risk: there's a cooling-off period, no interruption to your supply (you keep the same poles, wires and distributor), and the retailers handle the changeover. You can leave whenever you like on most plans.

Check these before you commit

• Do you have a smart meter? Some offers — including time-of-use plans and the federal Solar Sharer free-power window (live from 1 July 2026, offering a daily block of free electricity around 11am–2pm on participating eligible plans) — require one. Availability varies by retailer and state, so confirm before assuming you qualify.
• Concession and rebate eligibility. Make sure any state concession you receive carries across — you generally re-nominate it with the new retailer.
• Solar export limits and plan compatibility. If you have or are adding solar, confirm the new plan's feed-in terms and that your system is registered.
• Billing and payment terms. Direct-debit-only discounts, paper-bill fees and quarterly vs monthly billing all affect the real cost.

Re-run the comparison at least once a year. The plan that was cheapest for you eighteen months ago is rarely the cheapest today, and loyalty is not rewarded — the best rates almost always go to new customers.

We sell no plans and take no retailer commissions, so we've no reason to steer you anywhere. Sometimes the honest answer is that your current plan is already fine and switching won't move the needle — and if that's true for you, we'd rather tell you than sell you a new deal.
