It previously ran RIBA Publishing, RIBA Bookshops (which operates online and at 66 Portland Place), RIBA Appointments and RIBA Journal. These all now operate as part of the RIBA. RIBA Enterprises also included the Newcastle-based NBS (National Building Specification), which had 130 staff and dealt with building regulations and the Construction Information Service. In June 2018, the RIBA announced it was selling a £31.8 million stake in RIBA Enterprises, to LDC, the private equity arm of Lloyds Bank. In November 2020, NBS was sold to Byggfakta Group, a Sweden-based information services provider.
