Saiful presented the 2016 Royal Institution Christmas Lectures, entitled "Supercharged: Fuelling the Future" on the theme of energy, a commemorative lecture series for the BBC which celebrated 80 years since the Christmas Lectures were first broadcast on television in 1936. The lectures were broadcast on BBC Four, and achieved over 3.5 million interactions through the BBC broadcasts and social media. Saiful was interviewed before these lectures for articles in The Guardian. A demonstration in these lectures led to a Guinness World Record for the highest voltage (1,275 Volts) produced by a fruit battery using more than 1,000 lemons. Saiful later broke that record in 2021 after using 2,923 lemons to produce 2,307.8 Volts.
Saiful has served on the Diversity Committee of the Royal Society, and was selected for the Royal Societys Inspiring Scientists' project that recorded the life stories of British scientists with minority ethnic heritage in partnership with National Life Stories at the British Library. His outreach activities include talks on energy materials to student audiences  using 3D glasses organised by the TTP Education in Action at the UCL Institute of Education, London.  He was interviewed for The Life Scientific programme on BBC Radio 4 in October 2019.
On 23 November 2022, Saiful was an invited speaker at the Brian Cox & Robin Ince's Compendium of Reason charity event, which was at the Royal Albert Hall.
