Soon after retiring, Dannatt took up several consultancies within the defence industry. These included armoured vehicle and tanks manufacturer Ricardo and the high-profile private security firm Control Risks Group.
Since then, Dannatt has also undertaken consultancies with Typhon and Targetfollow, and with Imeon Logistics until July 2017.  He is currently chairman of Cadence Consulting, a board adviser to Photonis Netherlands BV and a senior adviser to Joule Africa, which develops sustainable energy projects in Africa.
Dannatt has been chairman of Royal Armouries since 2015, a role which was extended by the UK government until November 2018. He was the 159th Constable of The Tower of London and a Trustee of Historic Royal Palaces from August 2009 -July 2016.
Sunday Times sting operation
In 2012, Dannatt was one of several retired senior army officers targeted in a sting operation by Sunday Times journalists posing as representatives of a Korean drone manufacturer.
Dannatt reportedly discussed a fee of £100,000 for two days work a month:
Dannatt told the Sunday Times that he represented Capita Symonds, which was bidding for a £400 million contract to manage Ministry of Defence estates, and that he had managed to get himself a place next to Permanent Secretary Jon Thompson at a dinner for the Soldiers, Sailors, Airmen and Families Association, on the strength of the fact that they had both attended St Lawrence College.
Confronted by the Sunday Times, Dannatt said he had not been paid by Capita Symonds and did not have a contract with them. The company said he had not been instructed to lobby for the bid.
