So I emailed ‘First’ the bus company and asked them if they would be opening their live bus times to an API
Here is response
Good afternoon Mr Hearn,
Thank you very much for contacting us with your query and apologies it has taken such a long time to respond.
I have looked into this for you and can confirm that whilst this is something that we cannot offer access to right now, it is certainly something that will be made available within the next few months (we are working through the collation of data and how this will be presented currently) in a similar vein to the link described in your comments.
