It will be appearing on all cans, outer packaging and support materials for both the on and off -trade this month.
A spokeswoman said: "Carling is brewed using 100% British barley and is the only major UK brewer to use its own maltings.
"As consumers are increasingly looking to buy British and locally sourced products to minimise their impact on the environment and get the best quality products available, Carling is proud to be sourcing British ingredients."
The move will be supported by an outdoor campaign
