Received a business energy price rise?

Read the notice alongside your latest bill

• Find the date the new rates start and the fuel and site they apply to.
• Compare the old and new usage rates and daily supply charges, including GST on both sides.
• Look for changes to discounts, fees, usage blocks, demand charges or time-of-use periods.
• Check whether the notice concerns a price change, an expiring benefit or a new contract. These are different events.

Work out the impact at the same usage

Use energy consumed during a known billing period. Keep the consumption unchanged when comparing old and new prices so you can isolate the price effect. A change in trading hours or weather belongs in a separate usage review.

A fictional business using 1,000 kWh over 30 days, with a rate moving from 30c to 33c/kWh and supply from $2 to $2.10/day, would pay about $401.50 more over 365 days at the same daily use. This is an illustration, not a forecast or an available offer. The price change calculator separates the usage-rate and supply-charge effects.

Choose your next step

• Ask your current retailer for its available business offers and the full costs in writing.
• Compare eligible alternatives using the same consumption, network, GST basis and tariff details.
• Check exit fees and contract conditions before accepting another offer.
• If you stay, keep the notice and check the next bill against the new rates.

What if the notice or new charges look wrong?

Ask your retailer to explain the effective date, the contract clause and the charges you do not recognise. Keep the notice, bill and any written response. Notice requirements and customer protections depend on your state, customer classification and contract.

A contract term and a fixed-price period are different. Avoid assuming a rate cannot change just because the contract lasts a year. Larger commercial sites, embedded networks, demand tariffs and unusual supply arrangements may need a separate review.
