I have had an unsolicited txt from a company trying to get me to pre order my corresponding .uk Domain names for £99 and then a phone call with a reduced price of £50.
I agree I need to get the .uk name to help protect my business interests but not get ripped off in the process.
I refused to be taken in and went to my current domain name registrar 123- Reg. Logged into my control panel and matched up the UK with my .co.uk name and paid £9.99 ex vat, job done. So check with you current registrars and hosting providers.
.UK domains should be live in June 2014 at some point.
