Early life and business career.
Stefanou was born in Egypt, the son of a shopkeeper who had emigrated from Cyprus at age 14. The whole family left Egypt for the UK in 1959, following the political turmoil after the Suez Crisis, which lost his family their business. His parents reestablished themselves by starting a grocery shop in Battersea Stefanou arrived in the UK at age 6.
He studied chemistry at Imperial College London, graduating with a BSc. He started his industrial career working for Johnson Matthey (1974-1977) and Esso (1977-1980), before moving to John Doyle Construction in 1980.
Stefanou's brother Stef Stefanou also worked at John Doyle Group, and by 1999 Stef was the Chairman and Stelio was the Chief Executive. In 1999 they instigated a de-merger which split the company into two. Stef Stefanou retained John Doyle as the construction company, while Stelio Stefanou founded Accord as a separate company to run the longer-term public services and infrastructure maintenance contracts. Stefanou sold Accord to Enterprise plc in 2007.
Public service.
After selling Accord, Stefanou changed from running businesses to running charities. In 2008 he established the Stefanou Foundation to protect the interests of vulnerable people, especially the very young and the very old, and to support the commercial development of scientific ideas into viable businesses.

In 2013, he established the Stefanou Foundation Cyprus which aims to break new ground in addressing that country's social and economic challenges following the financial crisis, and he serves as its chairman.
In April 2015, he launched the "Healthy Relationships: Healthy Baby" (HRHB) programme for families suffering domestic abuse that are expecting babies.
Parents join this program during pregnancy and they are supported to bring an end to domestic abuse in order to nurture their baby’s early development. 
The Foundation is initially running two prototype projects, in Hertfordshire and in Westminster.
The police and crime commissioner for Hertfordshire, David Lloyd, visited the centre and he said he believes it can "reduce the number of people suffering from abuse and make society better and safer".
Stefanou personally funds the development and initial delivery of the HRHB programme as part of his overall funding to the Stefanou Foundation of £1.5M a year.
