BT Business and Public Sector was a division of United Kingdom telecommunications company BT Group that provided fixed-line, mobile, broadband and IT services to businesses (predominantly small and medium-sized enterprises) and the public sector in the UK and Ireland.

It also sold other vendors' products and services such as the Avaya IP Office business telephone system.

In April 2018, Gavin Patterson, then BT Group's CEO, announced Wholesale and Ventures was to be combined with the group's Business and Public Sector division into a newly-formed division, BT Enterprise.

It came after BT's decision to undertake a streamlining of its operations, in a bid to strengthen its offerings as a business.
