Questions about each
Energie
What does a unit of electricity cost on an Energie tariff?+
Energie charges a unit rate of €0.17 for electricity, and adds a standing charge of €35 on top. The unit rate is the part that follows the market, while the standing charge is the fixed part of the bill that stays the same whatever you use. Both figures are quoted in euros.
Is there an exit fee if I switch supplier early?+
The exit fee is €0, and the contract runs a fixed term of 12 months. A household can therefore move house, change supplier or renegotiate without paying to break the deal. On our data that exit fee position is 1 of 29 brands ranked.
Eni Plenitude
Is there an exit fee on the energy contract?+
No penalty charge applies to the energy tariff, where the exit fee is €0. Broadband is treated separately: the fibre line carries a deactivation charge if you cancel within the initial period, and that charge is reduced when you hold an energy contract with the same supplier. Leaving the energy side is simple; leaving the fibre side is not free.
What do I actually pay on the energy side?+
The unit rate is €0.17 and the standing charge is €144, and the standing charge applies whatever the household uses. Low-usage homes feel that fixed part harder, so the same tariff can look different from home to home. Both fuels, electricity and gas, sit on the same contract.
