There is a subscription of £30 per year for families, but it will not be mandatory for new members to subscribe, until they have provided documentation to confirm they were given a HPT. The annual subscription, paid for many years by our existing members, provided the funds needed to continue our research, discover documented evidence used for the IMMDS review and exposed the government and manufacturer's collusion in keeping Primodos on the market. This research has taken us across the UK and Europe, researching archives and libraries and provided for the cost of translating documents discovered in Germany. These documents provided significant evidence to be used by our legal team on behalf of our members. These funds are essential to enable us to continue our work. Although the subscription is not mandatory, it is a necessary resource we rely on.
