Reg 38 provides that:
(1) If a consumer withdraws an offer to enter into a distance or off-premises contract, or cancels such a contract under regulation 29(1), any ancillary contracts are automatically terminated, without any costs for the consumer, other than any costs under these provisions -
(a) regulation 34(3) (where enhanced delivery chosen by consumer);
(b) regulation 34(9) (where value of goods diminished by consumer handling);
(c) regulation 35(5) (where goods returned by consumer);
(d) regulation 36(4) (where consumer requests early supply of service).
(2) When a trader is informed by a consumer under regulation 32(1) or (2) of a decision to withdraw an offer or cancel a contract, the trader must inform any other trader with whom the consumer has an ancillary contract that is terminated by paragraph (1).
(3) An “ancillary contract”, in relation to a distance or off-premises contract (the “main contract”), means a contract by which the consumer acquires goods or services related to the main contract, where those goods or services are provided -
(a) by the trader, or
(b) by a third party on the basis of an arrangement between the third party and the trader.
(4) Regulation 6(1)(b) (exclusion of financial services contracts) does not limit the contracts that are ancillary contracts for the purposes of this regulation.
