Nell started his full-time radio career in 2002 at Island FM in Guernsey, one of the Channel Islands. He initially presented the late show, eventually moving to the evening show while also working in production and competition administration.
In early 2006 Nell moved to Beacon Radio, 5 years after first presenting shows on the station, to present drive time and after a reshuffle moved to mid-mornings. While Nell was at Beacon Radio the station won The award for 2006 Arqiva Commercial Radio Station of the Year. From June 2006 he started to provide cover on 96.4 BRMB.
BRMB
In October 2007 Nell moved to 96.4 BRMB as the full-time cover presenter, providing weekday holiday cover and presenting weekend breakfast. At the beginning of August 2008 it was announced that 96.4 BRMB, Beacon Radio, Mercia FM, Wyvern FM and Heart East Midlands would be sold to satisfy the Office of Fair Trading's ruling on the takeover of GCap Media by Global Radio. As a direct result of this, to replace The Global Radio network programming, Nell presented the networked mid-morning show on Beacon Radio, Mercia FM, Wyvern FM and Sunday breakfast on 96.4 BRMB from Monday, 25 August 2008. On 10 February 2009 it was announced that Nell would leave BRMB to join Hallam FM to present drive from mid March.
Hallam FM
On 16 March 2009 Nell presented his first weekday drivetime show on Hallam FM. Nell was part of the programming team that won UK commercial station of the year and Commercial radio marketing award for "Get Me to the Church on Time 2" at the Arqiva Commercial Radio Awards 2010. He also hosted Sunday mornings from 08:00-12:00.
From 24 November 2009 Nell started a daily 4–7 pm show on Heat Radio, which was voice-tracked, in addition to weekday drivetime on Hallam FM. The times of his Heat Radio changed to 3–6 pm from 5 July 2010. From 5 September 2011 Nell moved to evenings and Sunday mornings.
Nell returned to Free Radio to cover various shows from May 2012. Until Sunday 6 April 2014, he presented Sunday afternoons on the Free Radio network between 1300 and 1600 as well as providing regular daytime cover. From the launch of Free Radio 80s he presents 10am-2pm on Saturdays. From Monday 3 March 2014, Nell began presenting the regional breakfast show with Cat James on Free Radio Shropshire and Black Country. A week into the show, Cat and Ed became Cat and Nelly, referring to his surname after a conversation about school nicknames. On 16 July 2015, it was announced by Orion Media that from 20 July, Nell would be moving to present drivetime without his co-host Cat James. This slot was vacated by Tom Newitt, who moves to Free Radio Coventry & Warwickshire. Breakfast will be presented by Jo & Sparky who have previously presented drivetime on Free Radio Birmingham.
