How often should you switch energy plans?

A good rule of thumb is to check your energy plan at least once a year, and switch whenever a meaningfully cheaper deal appears. Here is why, and how to make it painless.

The short answer: check yearly, switch whenever it pays

There is no penalty for switching often, and for most Australian households there is no exit fee either, so the practical answer is: review your plan at least once a year, and switch whenever a meaningfully cheaper plan appears. Some people switch every year or two; others more often. What matters is not a fixed schedule but making sure you are never stranded on an overpriced plan for long.

The reason yearly is the minimum is that energy plans drift. Retailers change rates regularly, and many market offers discount for the first 12 months then step up — so the plan you happily signed up for can quietly become one of the more expensive ones without you doing anything. An annual check catches that drift before it costs you a full year.

Triggers to compare right away

Your bill jumped
If the bill rose without your usage changing, your rate almost certainly did — compare now.
A benefit period ended
Many discounts last 12 months. When they lapse, your plan can step up sharply.
You got a "price change" notice
Retailers must notify you of rate changes; treat it as a prompt to check the market.
Your circumstances changed
A new EV, solar, a battery, a baby or working from home all shift your usage — and the best plan with it.
You moved house
A new address means a new account and possibly a new network — the perfect, effort-free moment to compare.

Why people switch less than they should

The barrier is rarely money — it is effort and doubt. Comparing plans by hand is tedious, the rates are hard to read, and it is difficult to be sure the new plan is genuinely cheaper for your usage rather than just better-marketed. So people stay put, and retailers quietly rely on that inertia. The gap between what a loyal customer pays and what a switcher pays can be hundreds of dollars a year.

The fix is to make comparison so easy that an annual check takes minutes, and to be told clearly when a switch is actually worth it — rather than chasing every small difference. That way you switch when it genuinely pays, and ignore the noise the rest of the time.

Make it effortless with tracking

  1. Set a yearly reminder to review your plan — or let a tool watch it for you.
  2. Upload a recent bill to EnergySorted so your real usage becomes the benchmark for every comparison.
  3. Watch your Bill Health Score over time — it flags when your plan has drifted off the pace and a switch is worth making.
  4. Act on the meaningful gaps and ignore the trivial ones, so switching stays worthwhile rather than a chore.

Frequently asked questions

How often should I switch energy plans?

Review at least once a year and switch whenever a meaningfully cheaper plan appears. There is usually no exit fee, so there is no downside to switching more often — the key is never being stuck on an overpriced plan for long.

Is it bad to switch energy retailers too often?

No. Switching does not harm your credit or your supply, and most plans have no exit fee. You can switch as often as it pays to. The only thing to watch is giving up a conditional bonus (like a special solar feed-in) before it has paid off.

Will my power be interrupted when I switch?

No. Switching retailers is an administrative change — the same wires and network deliver your power, so nothing is physically disconnected. You simply start being billed by a new retailer, usually from your next meter read.

How do I know when it is worth switching?

When the cheapest available plan for your usage is meaningfully cheaper than what you pay now. Tracking your bill over time — for example with a Bill Health Score — flags when your plan has drifted so you switch on the meaningful gaps, not the trivial ones.

Does switching every year really save money?

For many households, yes, because plans that were competitive a year ago often are not today, and benefit periods step up after 12 months. An annual check-and-switch habit is one of the simplest ways to avoid paying a loyalty penalty.
