Anyway the ombudsman line said that I had a strong case and pointed out the reasons why. When I spoke to my employer i think they quickly realised that it wasn't a legitimate redundancy the roles are really the same and so they offered me the 4 weeks payout plus 4 weeks notice that they will pay out too. To answer your question though, they are classing it as a redundancy but it is really hush money IMO.
I'm happy with the 8 weeks, it will keep us going for another 4 moths and hopefully I can find something by then.
THANK YOU for all of your help ladies.
