What to consider
Energy tariffs explained
Fixed and variable tariffs
A fixed tariff fixes specified rates for a term; it does not fix the total bill because usage still varies.
Time-of-use tariffs
Prices change by time, so suitability depends on flexible consumption, metering and the full rate schedule.
Switching
Check supplier, contract dates, payment method, exit fees, customer service and any bundled conditions.
Comparison method
A fair comparison uses the same annual usage, region, payment method and full-year charge assumptions.
