In June 2010 he threw 41.25 to come fourth in a senior meet in Cardiff, and followed this with a second place in the World Junior Championship in the Czech Republic. In 2011 he was part of the Great Britain squad that travelled to Christchurch in New Zealand to take part in the IPC Athletic Championships, he finished 4th in the F42 javelin, throwing 38.31. In April he attended his second Junior World Championship, this time finishing third. Despite having to miss training to concentrate on his academic studies beforehand, his results in an IWAS Series meet in Stadskanaal in the Netherlands saw Moorhouse beat his personal best with three of his throws. His best of the three, 45.75m, was enough to give him first place. Then, two weeks later in Cardiff, he threw a 47.33 which pushed him up the global rankings.
