What about .UK instead of .CO.UK?
Basically, you own both WpHost.co.uk and WpHost.uk. Unless you can't afford $10-$20 to activate the .UK version some time before 2019. And why wouldn't you do that?
Here's how that works:
As the owner of WpHost.co.uk you have priority rights to WpHost.uk until the summer of 2019. That means that you can at any time between now and 5 years in the future -- choose to register WpHost.uk in addition to WpHost.co.uk.
After 2019, if you haven't already registered WpHost.uk, those grandfathered rights go away. So if nobody has claimed WpHost.uk by that time, then it becomes available to anyone to register. Registering WpHost.uk is something you can do when you get around to it. The cost is something like $10 per year. For non-British citizens, a trustee service (for another $10) would be required for .UK. No such requirement exists for .CO.UK. I think I've got that right. But for the final word in this policy, you can check link to Nominet's info. (Nominet is the .CO.UK / .UK registry.)
