Admiral Taverns will fund free BII membership for all new tenants.
The deal, for the length of the tenants' agreements, will give access to discounts on the BII's training schemes and professional services such as stock-taking, accounting and HR.
Admiral is the first pub company to offer free BII membership to licensees. However, existing tenants are not covered in the agreement.
Peter Thomas, interim chief executive of the BII, said: "This is a really progressive move by Admiral. It is fantastic that the company recognises the difference BII membership can make in helping and supporting both hard-working licensees and sustainable pub businesses."
BII membership costs £174 in the first year and £108 for subsequent years.
Members can call free helplines for advice on legal affairs, licensing, health and safety, and business and finance.
Membership also gives money off energy bills and business seminars, plus a subscription to BII Business magazine.
Suzanne Smith, head of licensee recruitment and training at Admiral, said: "Membership of the BII is a ‘must have' for anyone wishing to be recognised as a professional within our industry.
"By using the full range of benefits made available by the BII, we can help our licensees maximise the potential of their businesses."
Admiral, based in Chester, owns about 1,200 pubs.
The company's business development managers will have their memberships automatically renewed as part of the BII deal.
