The Advertising Standards Authority has upheld a complaint regarding the Indesit company’s new “revolutionary new four-door fridge freezer” under the Hotpoint brand Hotpoint Quadrio FF4DX (product advertised on Sainsbury’s Appliances site). The complainant challenged whether the claim “save up to 50% energy” misleadingly implied that the product could save up to 50% of the total energy used by a fridge freezer, rather than (merely) a saving in the energy required to restore the internal temperature of a compartment once the door had been opened.
