After making the mistake of creating and building my entire project in Unity 4.6 beta. I then discovered you cannot deploy web builds from the beta version.
However, whilst in work today I was enlightened to the knowledge that 4.6.1 is now out. After downloading and rebuild my game in this, I am now able to provide a working web link, yay! It does not make my game look as good as if it is downloaded and played, but it is easier to access.
Hope that may help anyone else in the same position who as not considered downloading and re building :).
