Gurcharan was born in the village of Nathowal in the district of Ludhiana (Punjab, India) on November 7th, 1948.
He was born into a Sikh family with a Jatt background. He is the second eldest of 5 siblings. Gurcharan comes from a family with a military background with his father, grandfather, father in-law and grandfather in-law having served in the British and Indian armies. His grandfather Bishan Singh Buttar fought in the British Indian Army in World War 1 and his father, Kartar Singh Buttar fought for the British Indian Army in World War 2 both being awarded medals for their bravery.
In 1954, the family moved to the neighbouring state of Uttar Pradesh (UP) where they settled in the village of Ramraj (in Meerut, Muzaffarnagar). The main family income was derived from farming. Growing up Gurcharan proved to be very studious and divided his time between studies and helping his father cultivate land.
At secondary school he received a merit scholarship for coming first in his O Level exams beating over 1,000 other students to the achievement. He continued and graduated with Physics, Chemistry and Mathematics from the Meerut University. He later achieved a Masters in Mathematics.
He is a fluent English speaker and is also fluent in Punjabi, Hindi and Urdu.
In 1971, he married Rajinder Kaur Jawanda, a registered nurse from Jagroan, Ludhiana (Punjab). Rajinder recieved her nursing qualifications from Christian Medical College Ludhiana.
In 1972, Gurcharan and Rajinder came to England and eventually settled in the town of Southall in Middlesex. Rajinder began working as a nurse at Hammersmith Hospital in Shephard's Bush, London and Gurcharan began working as a Rail Guard for British Rail and then a Clerical Officer for the Civil Service at Somerset House in Aldwych, London.
Gurcharan and Rajinder have three grown up children. All 3 were born at Perivale Hospital, Middlesex. They also have 5 grandchildren.
Whilst in this post[3] , Gurcharan managed a budget of £93m. His responsibilities included delivery of social housing, an efficient and responsive repair system and modernisation of stock. His main challenge was to regenerate council estates in the area. During this time, he spearheaded and was successful in attracting extra funding for the Estate Action Programme. This programme was focused on modernising derelict estates such as Golf Links estate in Southall and South Acton estate in Acton. In performing these duties, consultation was required with all stakeholders and these included Government Ministers, trade unions, clients and community as a whole.
During the same time, Gurcharan tackled unfairness in the housing allocation system by establishing and Charing the Race and Housing Working Party and implementing its recommendations. Housing allocation has since been made on needs basis rather than colour.
In addition, his tenure also saw a dramatic decrease in the number of families in bedsits down from 1800 to 653.
Whilst in this post, Gurcharan introduced kerbside recycling to all low-rise dwellings and free collection of scrap vehicles from resident’s front/rear gardens.
In these posts he oversaw investment in Southall and Manor House parks, the introduction of traffic calming measures in Southall and the resurfacing of 2 Southall car parks.
Gurcharan's tenure as Mayor was marked by his charity work. He managed to raise a over £35,000 - more than any previous Ealing Mayor. The charities included those related to the Meadow House Hospice, Polish ambulance services, Parkinson's Disease and the Iranian earthquake victims.
Gurcharan has stood and won in local government council elections in 1982, 1986, 1990, 1994, 1998, 2002 and 2006. He also stood for the Greater London Assembly in 2000 and 2004 but lost.
In May 2010, Gurcharan stood as the Parliamentary Candidate for the Conservatives in Ealing Southall -a Labour stronghold (for over 50 years). Gurcharan fought a fair and vigerous campaign which was based on the issues. The battle for 2nd place was won and he achieved a significant swing of 8.3% in his favour along with a 10.8% increase in vote share which gave him nearly 30% of the public vote whereas Labour's vote share decreased by 5.8%.
In the lead up to the 2007 Ealing Southall by-election (prompted by the death of the incumbent MP Piara Khabra), Gurcharan, along with 4 other Labour councillors (Manjit Singh, Maninder Kaur Keith, Jarnail Singh Jandu and Jagdish Gupta) defected to the Conservative Party.
The reasons given were primarily related to the selection process adopted by the Labour Party in selecting their candidate. The shortlist was criticised for being untypically narrow (only 2 candidates as opposed to the usual 5).
Eventually Virendra Sharma, a little known councillor from Hanwell was chosen and went on to win the bi-election.
