My junction box which is in the attic has enough wires in it. where can I put an extra cable from a double socket?

There are some rather complex rules for extending circuits. It depends on the type of circuit so a ring final, a unfused spur, a fused spur, and a radial all have different rules. With radials it also depends on size of cable used.

Job one is to work out what you already have. Using a RCD FCU is likely the best method for DIY extensions but until you know what you already have can't answer the question.
