Why do electricity retail tariffs change?
We're always working to help our customers, whatever circumstances they are in. To do this we work closely with a large number of organisations and consumer representatives, from social services and the Energy Ombudsman, through to financial and legal service providers.

Sometimes you might just need a little extra time to pay your bill. At other times more help might be needed, like a payment plan to help you budget better or because of unforeseen circumstances like chronic illness in the family, loss of income or other reasons. If times get really tough, we offer additional support through our ‘Keeping Connected’ program. Whatever the reason, please get in touch with us, so we can help.

Are network access charges changing?

The Economic Regulation Authority has confirmed there are no changes to Western Power’s network access charge price list in 2018/19. 

Are gas prices likely to increase?

ATCO Gas Australia is not increasing its network access charges. Therefore Synergy will not be making any changes at this time. 

We will keep you informed of any decisions relating to the gas network access charges, and how any changes may impact your business.


Why is Synergy changing prices again?

The setting of electricity retail tariffs is determined by the State Government.  These prices are reviewed each year.


Why have generation costs increased so much?

Currently, taxpayers like you are subsidising the WA energy infrastructure to the tune of $300 per household, per year. That’s enough money to build a new hospital every year. 

Under the current system, taxpayer funds are subsidising all residential energy bills, regardless of the person’s ability to pay. The changes will mean that most residential customers will be paying more directly for our shared energy infrastructure, such as poles, wires and electrical systems. 

This means that the more you manage your existing energy usage, using tools such as My Account from Synergy, the less you’ll pay on your electricity consumption charges. To find out more or register, visit



Why has my bill increased even though I am using less and less energy?

The reforms will mean that most customers will be paying more directly for our shared energy infrastructure, such as poles, wires and other electrical network components.

Why do we now charge an over the counter fee?
Australia Post governs a charge to Synergy each time customers pay their Synergy bills at Australia Post. From 1 July 2018, this fee will be a direct pass-through cost to customers who pay their Synergy bills over the counter at Australia Post.

Impacted customers can choose to avoid this fee by switching to Direct Debit
Why do we now charge a paper bill fee?
The paper based bill fee is a delivery based cost. Synergy incurs a delivery cost each time an invoice is sent to a customer. From 1 September 2018, Synergy will pass through the Paper based bill fee to customers who choose to receive paper invoices. 

Impacted customers can choose to avoid this fee by switching to paperless.
Why has the supply charge changed significantly for non-contestable electricity tariffs (excluding A1 residential)?
The State Government recently announced price changes for regulated electricity tariffs. As part of these changes, the daily supply charge has increased for each non-contestable tariff (excluding A1 residential) to align with Western Power’s fixed network costs. As a result, this component has increased by a greater degree than the change in variable rates. 

This approach was applied to the A1 residential tariff from July 2017.

Due to the individual supply charge and variable rate changes, the impact will vary for each customer based on their consumption and associated tariff. For example, the R1 tariff increases by an average of 4.1% on a customer’s total bill. However the L1 tariff decreases by an average of 1.5%. 

The changes as announced by the State Government  will apply to regulated non contestable electricity tariff customers from 1 July 2018.
If I pay more than one bill over the counter, how many times will I need to pay the Over the counter fee?

Customers will be charged $2.10 per transaction that is paid over the counter at the Australia Post.

For example, if a your business has 2 accounts, and you pay both of your Synergy bills in full at Australia Post in the same visit, you’ll incur two charges of the $2.10 Over the counter fee.

Similarly, if you have one Synergy bill and make multiple visits to Australia Post to pay portions of that bill, you’ll be charged $2.10 per payment towards your that bill.
