Yes I did see that post before, that's why I thought of contacting Welcome as I knew Macadam had ceased but didn't know where to start searching.
No I didn't request a SAR, I just phoned them and they emailed me back. Might send a SAR request but I think I will phone the FSCS first and see what they say.
I think the loans are probably too old to find any info on them though as they are all from the late 90's. I have had some other PPI complaints upheld recently so this is why I thought it might just be worth trying to find out about them.
Many thanks for your replies and help
