There is NO single central repository. The Government (including Minister Sarah Newton, Baroness Williams, Lord Keen of the Home Office) has clearly and repeatedly stated that there will be no choice of a single solution and that the open market will be allowed to flourish around modern slavery data. If you are worried about having to choose a register/repository and have no preference on approach then we recommend that you support all of them.  We have built in a user-controlled function to enable members to submit of statements to other registers from within tiscreport, in an effort to join forces with other open data initiatives. We need more collaboration and openness, not more silos.
The TISCreport register is not only increasing transparency with a data driven approach, it is the only modern slavery statement register partnering and funding the official UK Modern Slavery Helpline and Resource Centre, tendered by Polaris to our award winning charity partners Unseen. It is the ONLY register in an official partnership with the helpline, and as such supporting it by becoming a member will in itself be an action you can report in your future statements. Additionally, because we are the only register measuring company compliance quantitatively, you will be able to check your supply chains for non-compliance through our systems. This is not something you can currently do anywhere else.
Our own register is neutral with no ranking or tiering, and our focus is on data integrity to allow others to access and analyse on their own sites. Other repositories have chosen to rank and tier (if not on their own sites, then on others), which some businesses will find valuable in holding them to account. They are also far more geared towards use by the public, which is something our data enables our other partners via API. Ours is an international open data register that also enables easy compliance checking. With data analysis techniques and additional sources of supply chain risk data we aim to provide businesses access to best practice from their sectors. If this approach and these features are valuable to your business, then we would love for you to join us.
