The Corner saw off competition from 18 Feet & Rising, Hello People and Lucky Generals to land the account in a process run by AAR.
The agency will be tasked with creating the first above-the-line campaign for the life-insurance brand, which launched in 2012. Activity, which is expected to comprise TV, digital and print executions, will aim to increase awareness and sales.
Matthew Gledhill, Beagle Street’s managing director, said: "The Corner won against some stiff competition. The team immediately understood us strategically and nailed the creative challenge with work that we are excited about taking straight to market."
