Loyd worked with his second cousin's husband, Lord Wantage, who had formed the National Aid Society in 1870, the society helped the sick and wounded from war and Loyd worked abroad for the Society particularly during the Franco-German war and in Turkey and Serbia. Loyd was one of only two survivors of the original society when in 1905 it changed name as the British Red Cross Society and he became vice-chairman of the society's council. He was on the governing body of Abingdon School from 1901 to 1922.
