The energy price hike prediction has risen from 54% to 65% and now 78%! It could get even higher by then, who knows. These hikes will affect anyone not on a fixed rate contract. Once your contract ends, you will feel it deeply.
If you are not on a fixed rate contract, add 78% to your current tariff, see how much it will be. If you can find an 18 or 24 month fixed rate contract for less than that, think seriously about changing over to one BEFORE the end of September at the latest.
