Update: Just spoke to Orange on 150, they put me through to the iPhone department who have ordered a Nano SIM FOC.
Not convinced until it arrives, but, a step in the right direction at least.
I also spoke to them on Monday and was able to successfully order a nano sim free of charge, and that I should be with me in 3 working days. I think it's a case of speaking to the right person, the first two I spoke to said no. But I kept raining back on different days and the response gradually changed. Apparently ts supposed to be a 3.50 charge to swap on a sim only contract but he lady removed this for me without me asking, making it free of charge.
