On 5 November 2005 Morris challenged Scotland's John Simpson for the vacant British title at the Braehead Arena in Glasgow winning via unanimous decision over 12 rounds. He made a successful first defence of the title defeating the then undefeated Rendall Munroe again in Scotland with the location this time being in Edinburgh. On 9 December 2006 Morris made a second defence against previous victim Simpson and suffered his first defeat when a bad cut forced the fight to be called off handing victory to Simpson. On 7 September 2007 Morris got a chance to regain his title at the Grosvenor House in Mayfair and lost for the second time to Simpson with the fight this time being called off in the 7th round.
Following the second defeat to Simpson, Morris took some time off from the ring saying that he needed time to analyze the defeat and what he could do to change things. He eventually returned with a victory over Youssef Al Hamidi on 27 March 2009. Two more wins followed in 2009 against Jesus Garcia Simon and Pierre Francois Bonicel before being given the opportunity in 2010 to fight once more for the British title although this time up at super featherweight. His opponent for the championship bout on 5 March 2010 was Dewsbury'sGary Sykes who had earned the shot following an eliminator win against Manchester's Anthony Crolla. The fight, in Huddersfield, ended in a unanimous but very close points victory for the undefeated Sykes and a third career defeat for Morris. Reflecting on the tight nature of the contest Sykes said after the fight "It was a real close decision and a tough fight for me".Andy split from long time trainer Bob Shannon citing 'needing a fresh start'. Signing with Hatton Promotions having left Frank Warren, Morris rebounded from the defeat with a win over Georgian boxer Nugzar Margvelashvili on 24 May 2010, making light work of his opponent and saying that he was "hungry for another shot" at the British title. Morris' last contest was for the English Super Featherweight Title at Bolton Arena v Anthony Crolla. Although clearly winning every round at distance and utilising his greatest weapon of body shots Morris' tired in the second half of the fight and was eventually stopped in the 6th round. This signalled the end of what proved to be a relatively unfulfilled but successful career. Morris finished having won the English and British Featherweight Titles, an earlier Commonwealth bronze at lightweight after taking a string of Amateur honours. Morris returned to his Landscaping business and his expanding family.
