The development and maintenance of the OHA Website is funded by the W R Tanner Memorial Fund which was raised in recognition of his outstanding contribution to the Association.

The Old Haberdashers’ Association (OHA) is the body which, through a wide range of activities, helps the wide network of former pupils of the Haberdashers’ Aske’s Boys School to maintain links among themselves and with the School. This website provides a host of information on OHA activities and Old Haberdashers’ achievements, links to the sports clubs websites, access to Old Haberdasher databases and links to the School and to the Haberdashers’ Company.

The OHA has a long and successful history (since 1888) and enjoys close, friendly links with the School. One of its principal aims is to encourage members of the OHA in all parts of the world to keep in touch.  Its main activities include: 

• Social Programme:
  the OHA organises a wide and diverse social programme including musical entertainments, wine tastings, visits to interesting venues, galleries, theatres etc, University socials, a black tie Annual Dinner at Haberdashers’ Hall, regular lunches for retired members, close links with school CCF activities. Event locations vary from the School and OH clubhouse to central London and regional venues.
• Networking:
  connecting Haberdashers in similar professions or with similar interests (e.g. the City, medicine, media) through events, talks, directories & informal contacts.  The OHA also works with the School to enable boys to benefit further from the expertise and knowledge of the diverse community of Old Haberdashers, for example through careers advice and work experience opportunities.
• Reunions:
  Year group, anniversary and regional reunion events
• Sports:
  Active and successful Cricket, Rugby and Football clubs (based at its Borehamwood sports ground) and Golf and Rifle societies which field regular teams in league and cup competitions. Informal matches have been organised for other sports e.g. Hockey, Tennis & Water Polo. There is an OHA sports day at the school in the summer when OHA cricket teams play against the school at various levels.
• Involvement in School events. These include the annual Remembrance Day CCF parade at the school where the OHA President lays a wreath on the OHA war memorial.
• Communications:
  Members receive regular e-mail newsletters and a substantial annual magazine with news and features on Old Haberdasher and School events and achievements.
• Charitable Activities:
