The UKPAC register allows you to search for organisations or indvidiuals who are registered as lobbyists, and also to search by client. Staff listed may be employed or providing consultancy services. The register also details organisations that employ individuals who are registered under their CIPR membership.
If you want to see if an organisation is using lobbyists then you should search by “Client”.
Search tools use the information as it is entered by the registrant. If your search does not come up with information you thought might exist you might wish to search again using a shorter form of the organisation or individual name. You can also use the “sounds like” button to broaden your search.
Further help and information about the register and how to search it can be found here.
