When Chris Bonington was recruiting for the large, siege-style expedition to climb the South West Face of Everest, Boardman was recommended by Paul Braithwaite as a talented climber who would be compatible with other team members. The expedition was successful in placing the first two Britons, Doug Scott and Dougal Haston, on the summit on 24 September 1975. Boardman and Pertemba, the expedition's head Sirdar, reached the summit on 26 September. On their descent, they met Mick Burke a short distance below the summit and still ascending. They waited for him at the South Summit in deteriorating weather, but Burke was never seen alive again.
