Barclays had been running the ad for its home insurance promotion, which offered to beat consumers' home insurance renewal quotes and give them 拢50 when they switch.
When it launched the offer in January it promised to lower its price by up to 拢475 to beat its rivals. It changed this limit in April to 拢100.
However, by failing to change its TV ad until May 25 it has landed in trouble with the Advertising Standards Authority. The Bartle Bogle Hegarty spot features a Barclays employee excitedly leaving a message for his boss, having thought up the offer.
Two viewers complained to the ASA that the original ad was misleading because it did not make clear that Barclays would only drop its price by a maximum of 拢100.
The ASA said the limit of 拢100 was a significant restriction on the offer that should have been made clear to viewers in the ad itself.
In contrast, the original ad did not refer to a specific limit. The ASA had earlier ruled that this was justifiable because the original 拢475 limit only affected a small number of people.
The ASA welcomed the changes to the replacement ad but judged that Barclays had breached rules by continuing to broadcast the original ad for more than one month after the change.
