There was a three-way pitch for the account. The incumbent agency was Homestyle PR.
Smeg, which is based in northern Italy, produces a range of luxury domestic designs including kettles, toasters, range cookers, ovens fires, fridges, freezers and washing machines.
John Davies, brand manager at Smeg, said: "Smeg continues to grow at a rapid pace with some extremely exciting developments in the pipeline. This coupled with a prolific number of new product launches planned for this year, the most in the company’s history, has led Smeg to change its media strategy.
"Little Red Rooster was recommended for its ability to expose brands to new audiences, thanks to its extremely strong press relationships across diverse media sectors."
In addition to the new win, the agency has hired Metro technology editor James Day as director of new business development.
Day has spent the last six years at Metro, developing its consumer tech section, Connect. Before this he worked at Zoo and Look magazine.
Day said: "I’ve worked with LRR over a number of years and it was obvious from the off the firm operated very differently to the hundreds of other PR firms I dealt with on a daily basis.
"There are great similarities here with what we were trying to build – and achieved - on Metro."
The agency currently works with Bisque Radiators, Victoria + Albert Baths and Ruark Audio.
