Ok - it should do. If not under the Consumer Rights Act 2015 then the terms may not be fair if it is not made obvious what the charge is.
Section 62 states:
62Requirement for contract terms and notices to be fair
(1)An unfair term of a consumer contract is not binding on the consumer.
(2)An unfair consumer notice is not binding on the consumer.
(3)This does not prevent the consumer from relying on the term or notice if the consumer chooses to do so.
(4)A term is unfair if, contrary to the requirement of good faith, it causes a significant imbalance in the parties’ rights and obligations under the contract to the detriment of the consumer.
(5)Whether a term is fair is to be determined—
(a)taking into account the nature of the subject matter of the contract, and
(b)by reference to all the circumstances existing when the term was agreed and to all of the other terms of the contract or of any other contract on which it depends.
(6)A notice is unfair if, contrary to the requirement of good faith, it causes a significant imbalance in the parties’ rights and obligations to the detriment of the consumer.
So if it is unfair and not brought to your attention, it can not be enforced.
Can I clarify anything for you about this today please?
