Was sceptical initially, but after reading the reviews I decided to give it a shot as I would rather spend an extra £137 than thousands trying to reapply. I received the pack via email and it was full of information and templates. They take many situations into account and inform you accordingly. I decided to follow the instructions fully. A month later I was successful. This pack made it easy to manage documents, a full array of necessary and optional documents were provided. Having the DIY pack really eased my mind about forgetting potential documents. 100% recommend.
