Jon maybe best known for being the original voice of Siri on Apple's UK phones, but he was a well known and widely recognised voice over before then. After leaving Channel 4, he spent 3 years as the main promotions voice of BBC 1 and 7 years as the voice of Sky Movies.

He has voiced numerous high profile advertising campaigns , including adverts for Duracell, The Mirror, The Times, Nokia, Acuvue and the inflight entertainment for British Airways.

He also works as an Awards Ceremony announcer - what is known in the trade as "Voice of God". From the Millies and the National Business Awards to the Asian AwardsThe Railway Children Ball and the Mobile News Awards, it's Jon's voice announcing the nominees and congratulating the winners.

 
Jon is the ultimate professional. He is arguably the best voice-over man in the country but also excels at managing his very successful business empire of top class talent and being a highly sought-after conference host. I have worked with him for many years in the television, radio and corporate arena and can highly recommend him as someone who will bring great experience, creativity and talent to any project
