Hi @Andyhallmotox.
Welcome, thank you for reaching out to Sonos Community since you already tried some troubleshooting steps let me try to assist you.
Have you checked the Spotify subscription to if it's still in Sonos application?
If Spotify still in Sonos application, try to disable and enable the Sonos skill in the Alexa application.
This link might help Set up an Amazon Alexa device to control Sonos.
Let us know if it works. If you need help with any other information, please be sure to let us know.
After reading a couple of replies, and trying to decipher the bits I could understand I reset all my speakers and set up a new Amazon account and Alexa account. it all now works again. “Alexa play Spotify” and away she plays.
Thanks for the help. I think this is the easiest fix.

Glad you found an alternative way to fix the issue, in any way this issue reoccurred again in the new amazon account, I suggest contacting amazon might be the best option.
