No, you don't need to take photocopies.
In fact, if you are uploading, you don't even need to take the originals to the appointment because you will have already submitted all your documents.
However, we do recommend taking your original documents to the appointment, just in case something didn't scan/upload correctly and they need to redo it.
Just a note that it's actually much easier for us to help you if you can keep all your questions about your application in just one thread, rather than starting a new one each time you have a different question, so that everything you have asked, and all the advice you have been given, is all on one page that we can refer to quickly and easily if we need to. You currently have 7 active threads for your ILR application, which means each time you ask a question, we potentially have to search through all the others first to remind ourselves of your situation.
