they shouldnt end up ever going to the http://mydomain.co.uk
That address isn't a problem, it's https://mydomain.com which is the problem. I agree that people shouldn't go there, but some people will and it's simply not acceptable that they end up on a server page when they do.

Your solution is partly correct. I say "partly" because I don't see the point in putting up with something substandard to save some money when sticking with it over a period of months could cost you more in lost business.
