Section 75 vs Chargeback

If you paid with a credit card and the transaction was between £100 and £30,000, you may have a stronger claim under Section 75 of the Consumer Credit Act 1974. This makes Santander UK jointly liable with the merchant.

Chargeback is useful for debit card purchases or credit card purchases under £100, where Section 75 doesn't apply. You can submit both a Section 75 claim and a chargeback simultaneously.
