Hi I need to send my was renewal form back but I have been given two different addresses to return it to. Envelope that came with the form has centre for health and disability, london bsc, mail handling site a, Wolverhampton, wv98 2es. But I got a letter today to remind me to send form back in time with. London, centre for health and disability assessments, London bsc, 333 Edgewater road, london, nw96td. The reminder letter says send to that address so I've no idea which is correct.
