Renewal Rules for .UK Domain Names
While most of the domain TLDs (like .com / .net / .in) expires as per its registration date, rules are different in case of .UK domain names. The .UK domains expiring on any day of a given month should be renewed or deleted before the 25th of the same month.
So even if your .UK domain is expiring on 24th or 26th of a month, you got to renew it before 25th otherwise it will be deleted on 25th of the month.
So, be cautious and remember to renew your .UK domain name before registry presses Delete button.
