The Octopus Tracker tariff for gas and electricity is a variable tariff which follows the wholesale price of energy using a set formula.
Note that with the current extremely high wholesale prices both the electricity and gas tariffs have been capped to protect the consumer.
It is possible to select tracker for gas and another tariff for electricity or the other way around.
