Perth, Western Australia – Western Australian households are set to see their electricity bills increase by 2.75% from July 1, 2026, as confirmed by Synergy and the State Government. This rise in the regulated residential tariff, known as the Synergy Home Plan (A1), comes amidst the unveiling of the WA State Budget 2026-27, which simultaneously pledges over $1 billion in cost-of-living relief for West Australians.
The tariff adjustment, applying to both the fixed daily supply charge and the electricity charge, is a direct outcome of the State Government’s annual review of regulated electricity prices. For customers on other Synergy tariffs, including time-of-use plans, a consistent 2.75% increase will also apply.
“The Cook Labor Government will deliver more than $1 billion in cost-of-living support for Western Australian families this year, including a new $100 Fuel Support Payment to assist drivers with the rise in fuel costs.”
This latest increase follows previous adjustments, including a 2.5% rise in the Synergy Home Plan (A1) from July 1, 2025, which, combined with the removal of a $400 annual electricity credit, significantly impacted household costs. While the current increase is less steep in percentage terms, it adds to the cumulative financial pressure on consumers.
Understanding the 2026-27 Electricity Price Changes
The 2.75% increase effective from July 1, 2026, will be reflected in bills issued from that date onwards. This adjustment is influenced by the rising costs of generating and providing electricity, as well as maintaining the state’s electricity network. Synergy, the primary electricity retailer in Western Australia’s South West Interconnected System (SWIS), indicates that standard fees and charges related to managing accounts, new connections, or meter changes may also see adjustments.
For a typical Perth household, the exact dollar impact will vary based on individual consumption patterns. As of July 1, 2025, the Synergy Home Plan (A1) supply charge was 116.05 cents per day, and the electricity charge was 32.3719 cents per kWh. A 2.75% increase would push these figures higher, directly impacting the total bill.

| Component | Current Rate (July 2025) | New Rate (July 2026, est.) | Percentage Increase |
|---|---|---|---|
| Daily Supply Charge | 116.05 c/day | 119.24 c/day | 2.75% |
| Electricity Charge | 32.3719 c/kWh | 33.2625 c/kWh | 2.75% |
Note: Estimated new rates are based on a direct 2.75% increase to the July 2025 figures and are illustrative. Final rates will be confirmed by Synergy based on the State Government’s determination.
State Government’s Cost-of-Living Relief Package
In response to ongoing cost-of-living pressures, the Cook Labor Government’s 2026-27 State Budget, handed down on May 7, 2026, includes a substantial package of over $1 billion in relief measures. While not all directly target energy bills, some key initiatives aim to alleviate financial strain on households:
- Energy Assistance Payment (EAP): The budget allocates $51 million for energy bill relief measures, including a 10% boost to the Energy Assistance Payment, Dependent Child Rebate, and Air Conditioning Allowance. This is designed to provide targeted support to eligible concession card holders.
- Fuel Support Payment: A significant measure is the $198 million Fuel Support Payment, providing a $100 payment to all Western Australians with a valid driver’s licence via the ServiceWA app. While not directly an energy bill rebate, it helps offset transport costs, freeing up household funds for other essentials.
- Carers Gold Card: A new initiative includes the establishment of the Foster and Grand Carer Gold Card, providing $377 of energy bill relief, recognising the vital service carers provide.
This targeted assistance is part of a broader strategy to support WA families, with a family of two children potentially receiving over $2,100 a year in total assistance, and up to $3,600 with concessions.
Navigating Rising Energy Costs
For Western Australian residents, understanding these price changes and available relief is crucial. The combination of increased tariffs and targeted relief measures means that proactive management of household energy consumption remains paramount. Energy efficiency upgrades, such as investing in heat pump hot water systems or improving home insulation, can provide long-term savings.

Furthermore, Western Australia continues to see significant growth in rooftop solar adoption. For households able to generate their own power, solar panels offer a buffer against grid price increases. Synergy also offers Distributed Energy Buyback Scheme (DEBS) credits for surplus energy exported to the grid.

While the State Government’s relief package aims to cushion the impact, the 2.75% tariff increase underscores the ongoing need for households to actively manage their energy usage and seek out eligible concessions or alternative energy solutions.
