Umunna was educated at Hitherfield Primary School in Streatham, South London, and the Christ Church Primary School in Brixton Hill. His parents felt that the local state school had "given up on him" and so moved him to the boys'independent senior school St Dunstan's College, in Catford in south-east London, where he became Deputy Head Boy.
