Snow presented his first programme in October 2002 just after graduating from university, co-presenting the BBC's 60th anniversary special on the Battles of El Alamein with his father Peter.[9] The two then collaborated to present an eight-part documentary series called Battlefield Britain, which aired in 2004, and won a BAFTA Craft Award for special effects. The same year, Snow won a Sony award as one of the presenters on the LBC Boat Race coverage. Snow presented on the Canadian Broadcasting Corporation's specials, with his mother Ann MacMillan, for Queen Elizabeth II's funeral and King Charles III's coronation.
Snow has presented on many state occasions such as the 200th anniversary celebration of the Battle of Trafalgar, Beating Retreat 2006, the 60th anniversary of the end of World War Two, the 90th anniversary of the Armistice in November 2008, Trooping the Colour and the Lord Mayor's Show. Snow again collaborated with his father to present BBC 2's 20th Century Battlefields and its print edition.[10] The series covers battles all around the world and is presented in similar fashion to the first Battlefield Britain.

In August 2014, Snow was one of 200 public figures who were signatories to a letter to The Guardian expressing their hope that Scotland would vote to remain part of the United Kingdom in September's referendum on that issue.[62] In June 2019, Snow wrote in a Twitter thread [63] if Brexit happened and if the Scottish National Party won a majority of votes in Scotland, he would "get" why Scottish people would want to have a second referendum, as leaving the European Union could "put up barriers" for Scotland. He was then asked if this meant he now advise Scots to vote for independence, and he replied "No way. One thing Brexit has taught me is the utter insanity of trying to rip countries apart".[64]
