The point of this post was to say there are companies already processing claims of this sort, everyone is placed into a group and they then claim as one entity. The aim is to get as many workers claiming as possible as the power really is in numbers as Uber proved and those drivers are now beginning to see the benefit of holiday pay, pension etc.
If you would like to know the website to visit and register your free claim just PM me and I will provide it, I would stress that you will be required to provide copies of payslips, P60 or Self Assessments in order to be clear of how much you can claim for.
