Public Sector Mapping Agreement

Not one of the above?

What if I am not one of those organisations?

In addition to those not specifically defined or named in the regulations, there are other public organisations that could become members.

For example, when an application is reviewed, one of the most commonly looked at areas is “bodies governed by public law”. The Regulations defined this as meaning bodies that have all of the following characteristics:-

  • they are established for the specific purpose of meeting needs in the general interest, not having an industrial or commercial character;
  • they have legal personality; and
  • they have any of the following characteristics:
  • they are financed, for the most part, by the State, regional or local authorities, or by other bodies governed by public law;
  • they are subject to management supervision by those authorities or bodies; or
  • they have an administrative, managerial or supervisory board, more than half of whose members are appointed by the State, regional or local authorities, or by other bodies governed by public law;

In these circumstances, the applicant would be asked to provide documentary evidence of how:

  • the criteria are met
  • they receive and use public funds
  • their activities meet the ‘Core Business’ definition contained in the PSMA member licence

Are there any exceptions to this?

The terms of the PSMA does allow for OS and BEIS to agree to allow certain other bodies to become members for example, where it is in the national interest. Under this heading, it has been agreed that the contributing members of the UK Search and Rescue (UK SAR) have been able to join the PSMA. See this information on how associate search and rescue members can get access.

Organisations that OS and BEIS have agreed as not being eligible.

The following bodies are not eligible to join the PSMA:

  • Those whose remit is mainly in Scotland (and are therefore covered by other arrangements for example, One Scotland Mapping Agreement)
  • Any public or private limited company (including whether limited by shares or guarantee), unless Ordnance Survey and BEIS have agreed otherwise
  • Housing associations
  • Social enterprises
  • Community interest companies
  • Schools (whether state, public, free, academy, independent or private

Note: although these organisations are not eligible, they can still get access to information from members. For more information see the public sector licensing guidance.
