Would you like the professional designation that identifies you as one of the very best commercial property agents in Europe?

The SIOR Designation

The SIOR Designation is a professional accreditation for the most highly qualified and successful real estate practitioners. Our designates carry an exceptional transactional history in brokerage, fee-based services, or executive management.

Within SIOR Designation there are six categories that identify you as a specialist in certain real estate disciplines. They are:

  • Industrial
    A realtor specialising in industrial transactions
  • Office
    A realtor specialising in commercial office transactions
  • Industrial and Office (Dual)
    A realtor who handles both industrial and commercial transactions
  • Sales Management
    An experienced sales manager who oversees a team of at least 10 real estate sales or leasing agents
  • Executive Management
    An experienced manager who oversees the operation of at least 100 sales or leasing agents across three or more offices
  • Advisory Services
    A realtor who works on a consultancy or advisory basis

Regardless of your specialist area or specific role, every SIOR designee carries the highest level of knowledge and is recognised as such by developers, lenders and investors. This reputation is backed up with quantifiable success and a commitment to the kind of continual professional development that maintains your position as the very best in your field.
