In Perth, most residential customers are supplied by Synergy on regulated Western Australian tariffs, so your bill mainly reflects electricity use, daily supply charges and any applicable concessions or fees. Check the bill’s usage in kilowatt-hours against the same period last year, and look for appliances such as heaters, air conditioners, hot-water systems and pool pumps that may be driving consumption. Contact Synergy to ask about payment plans, hardship support or billing concerns, and check whether you qualify for a WA Government concession through the official services portal. Your final charges and assistance options depend on your account and circumstances.
