The club has hailed the support of official stadium partner Northern Commercials, whose agreement will come to a formal close at the end of the season.
Northern Commercials have sponsored the club for close to 10 years.
And after taking over the naming rights of Valley Parade’s Midland Road Stand, in 2016 the Brighouse-based commercials vehicles giant became the Bantams’ stadium backer.
City commercial manager Michael Shackleton said: “We would like to take this opportunity to thank Northern Commercials for their involvement with the club over the last nine years - and for their sponsorship of the stadium for the last three years.
“In the coming weeks, we will be actively looking for a new stadium partner.
“With attendances averaging around 16,000, we believe stadium sponsorship can provide fantastic exposure - locally, nationally and across the world.”
Steven Lahy, marketing manager of Northern Commercials, added: “Bradford City has been a long and valued partner for Northern Commercials and we are proud to have been the main stadium sponsors for over three years.
“On behalf of everyone at Northern Commercials we would like to wish the club all the best for the future.”
