At the 2016 European Championships held in London, Peaty retained both of his individual titles in the 50 metre breaststroke and the 100 metre breaststroke, comfortably winning all of his heat, semi final and final swims and sharing the podium with his team mate Ross Murdoch on both occasions. He also retained both of his relay titles winning the 4 × 100 metre medley relay with Walker-Hebborn, Guy and Duncan Scott, and the mixed 4 × 100 metre medley relay with Walker-Hebborn, O'Connor and Halsall. He did not enter the 200 metre breaststroke event and had never entered the event again at a major championship.
