The police send a copy of the statements to the defendant's solicitor, and the solicitor will send a copy to the defendant. So yes, the defendant will have copies in his house.
Your name and address will only be on the back of the statement, the defendant gets the front pages only.
The defendant and his solicitor need to see the witness statements well in advance of the trial in order to prepare the defence.
