Pescod joined the civil service in British Hong Kong in August 1981. He became an official Justice of the Peace in 1998. Between June 2001 and November 2004, he was Deputy Commissioner for Tourism. Pescod was posted to Brussels as Special Representative for Hong Kong Economic Trade Affairs to the European Communities between 2006 and 2008. He received the Chief Executive's Commendation for Government/Public Service in 2006. From 2008 to 2010, he was Permanent Secretary for Commerce and Economic Development. From then till 2014, he was Permanent Secretary for Transport and Housing and Director of Housing. Upon his return from his post in Brussels, Pescod and his wife bought a house in Clearwater Bay, Sai Kung, as a retirement home and investment. In 2012, during his tenure as chief of housing, Ming Pao Daily reported that several unauthorised structures had been found at this property. This negative attention came at a time when other prominent officials, including Chief ExecutiveCY Leung, were found to have similarly illegal structures. He retired from the Planning Department in 2014 after thirty-three years in the civil service to join the West Kowloon Cultural District Authority. Later that year he was awarded a Gold Bauhinia Star for "contributions in the areas of economic and trade, communications and technology, as well as housing." He joined the semi-independent WKCDA as chief operating officer in October, and rose to the CEO position when Michael Lynch stepped down a year later. His prominent position at the WKCDA was not well received by lawmakers or the arts community. EJ Insight noted it appeared to be a pro-government move at a time when 16 board members were due to retire at the end of their 6-year terms. At one point, the project was controlled by Henry Tang, failed Chief Executive candidate, whose appointment was seen as a conciliatory play by the elected victor Leung.
Personal life
Pescod was born in Sierra Leone, West Africa, and grew up in Thailand. He went to Sedbergh School in England between 1972 and 1977. He spent 1977 to 1981 at Leeds University, at which he was awarded a Bachelor of Arts in Sociology with Honours. EJ Insight reported in 2014 that he was living in a 5000sf house on Victoria Peak leased for $230,000 a month, of which he was paying just $16,000 due to civil service benefits. Pescod's forays into public life beyond the civil service include chairing the PeakSchool Council, the Children's Heart Foundation and the Valley Rugby Football Club, and a position on the Board of the Ocean Park Corporation in the early noughties.
