Manchester nightclub Pure and service company Serco have also been announced as sponsors of the event, which takes place at the Manchester Evening News arena from April 9 to 13.
Kellogg's has been named the official cereal of the championships and will invest in training three female life guards and 48 children to obtain their swimming helpers certificate, encouraging them to qualify as swimming teachers.
Serco Leisure, which manages Manchester's Aquatic Centre, the official training venue for the event, will be working with more than 35 local swimming clubs to support the development of the sport and encourage participation in swimming. The company is also giving ticket holders at the championships a free swim at any of its 60 leisure centres across the country.
Northern Rail, which operates local and regional train services across the north, will be the official regional rail partner of the championships and will advertise the event across all its stations, as well as distributing leaflets to over 220,000 homes across the northern network.
GMG Radio's 105.4 Century FM will be the official radio partner for the championships and will run on-air and off-air support initiatives in the run-up to the event.
Pure will become the official hospitality venue, hosting the aftershow party for the events participants, sponsors, partners and volunteers, on Sunday April 13.
Marc Hope, director of rights marketing at Fast Track, said: "I'm thrilled to welcome these five partners to the growing sponsor family, we are proud to have them on board.
"They will play a very special role in ensuring the championships are both a huge success and leave a lasting legacy."
The Manchester Evening News was announced as a sponsor in August. It will report on all the championship news, as well as advertising the five-day event to readers.
Sports marketing agency Fast Track, which brokered the deals, is still in talks to fill the remaining commercial partnerships, particularly two at national partner level.
