Immediately after the Great War the Lodge went from strength to strength. Returning soldiers looked for the good things that service life had brought them (comradeship, discipline and fun) and many turned to the Freemasons to provide this. By 1921 the membership was just about 60 members and by the end of the decade it was more than 70 members. At the same time, during the 1920's and 1930's it was usual for visitors to be in the 30 to 40 range and so a usual Caxton Lodge meeting of the period would often touch the 100 mark.
In 1930 the Lodge held its Golden Jubilee and in the same year received its first home-grown Officer of Grand Lodge when WBro Luke was appointed PAGDC.
In October 1931 the Lodge had its first meeting in the new Freemasons' Hall (pictured) and the 1930's continued to be a buoyant time for the Lodge.
By the end of the 1930's however, war clouds loomed again with the start of WW2 and the Lodge had to get used to rationing.
After WW2 the lodge again continued to flourish nicely. It was a great supporter of charity and became a patron of the Royal Masonic Hospital (pictured) in 1962. This rude health of the Lodge remained in that phase until the oil crisis of the early 1970s, which when combined with the members that joined the Lodge after the Great War beginning to die-off meant that the Lodge drastically reduced in numbers. By 1974 the lodge had reduced to 45 members. By the 1980s and on the Lodge's centenary celebrations the membership was touching 50 and 30 Brethren would normally attend a meeting.
