Data Governance and Quality

Code of Practice


In September 2013 the GLA published a Code of Practice in the Use of Statistics. The purpose of the code is to improve the quality of data and promote the proper use of statistics in a public environment. Based on the UK Statistics Authority’s own code, the GLA’s code has been designed to reflect its status and responsibilities with regards to data. It aims to: – establish common standards around the use of statistics; and – ensure a coherent and trustworthy service to the user of statistics.


How the Code is Applied Across the GLA Group



All of GLA, TfL, LFEPA and the London Legacy Development Corporation have signed up to the implementation of the Code of Practice in their own organisations. Details of the data standards in each organisation can be found here.The Mayor’s Office for Policing and Crime (MOPAC) and GLA will address how the code is to be applied in relation to MOPAC and Metropolitan Police data once the further transfer of staff with data responsibilities into MOPAC has been approved by the Home Secretary, as is required under the Policing and Social Responsibility Act.


Open Data Charter

This charter sets out the GLA’s own position with regard to the Open Data ecosystem in London and the wider city data environment. Under a set of broad principles, we outline our commitments as the strategic authority to provide, promote and drive the use of open data in the pursuit of a better London.


Data Release Schedule


To tell users what data is being released and when, we also produce and regularly update a Data Release Schedule.
