Harpreet Singh was born to Dalit Sikh family in Gidderbaha in May 1972. His father was a village granthi.[4][5] After completing his schooling, he graduated from Guru Kashi Gurmat Institute where he received religious education.[5][6] In 1997 he joined the Shiromani Gurdwara Prabandhak Committee (SGPC) as a "pracharak" (preacher) and was appointed as head granthi of Gurdwara Darbar Sahib in Muktsar in 1999.[7]
Harpreet Singh resigned as the acting Jathedar of Akal Takht on 16 June 2023, being replaced by Raghbir Singh, the jathedar of Takht Kesgarh Sahib. His resignation came after controversy was created over him attending the engagement of Aam Aadmi Party leader Raghav Chadha with Bollywood actress Parineeti Chopra in May 2023.[8]
^The Sarbat Khalsa in 2015 appointed Baljit Singh Daduwal as jathedar of Takht Sri Damdama Sahib. However the SGPC refused to recognise its authority.[1]
