A price guarantee sounds reassuring, yet the wording matters. It can cover different parts of the tariff for different periods.
What a guarantee can cover
A guarantee may cover the supplier's price components, while taxes, levies or network charges can be excluded. The contract wording defines the scope.
Check the start and end date as well. A guarantee that expires shortly before the contract can be extended deserves particular attention.
How to use it in a comparison
A guarantee is one element beside the energy price, basic charge, term, cancellation period and bonus conditions.
The better question is not simply whether a guarantee exists, but whether the complete set of terms suits your household and expected consumption.
A short checklist
- covered and excluded price components
- start and end date
- contract term and renewal
- energy price and basic charge
