Spencer was born in Woolwich in 1969 and lives in Greenwich Borough with his wife Liz and their two children, Kate and Arthur.  Spencer and Liz got married in 1999 at the Trafalgar Tavern in Greenwich.

Spencer’s father was a local Veterinary surgeon who died when Spencer was 11 years old. Spencer attended the local independent School; Colfe’s on an assisted place and went on to get degrees in Politics/Economics and Britain in the European Union. He has worked as a Betting Shop Manager, Customer Services manager and for the Office of Fair Trading but in 1996 he discovered a passion for teaching and started work as a teacher at Kemnal Technology College in Footscray. He returned to Colfe’s as a teacher of Economics four years later, shortly after the birth of Kate. Spencer is currently Director of Sixth Form, having been in charge of years 10/11 for five years previously. His achievements as a teacher include the fact that he taught the first ever students to get A* grades at Mathematics GCSE at Kemnal and in 2003, 3 out of 5 of his Business Studies GCSE students were placed in the top 5 nationally (out of 61,000 students) in 2005 and in 2007 & 2008 students from his Government and Politics class were placed in the top ten nationally.
 
Spencer was elected as a councillor on Greenwich Council in 2002 and has been Leader of the Conservative Group since 2006. He is still a member of the Old Colfeians Rugby Club, having played for the 4th XV there for almost a decade. His son Arthur is now playing in the under 7s rugby team and Spencer is finding a new way to enjoy the sport (although he desperately misses the rolling maul!) 
 
Spencer has lived in Eltham since 1995 and his family are delighted that he has been chosen as its Parliamentary spokesman. He understands only too well the problems facing the Greenwich and Woolwich constituency
