You will be better researching the qualifications in the specific country you are going to. A Masters in Scotland is an undergrad qual for example, and there are several countries where a 'Bachelors' is not deemed equivalent to a UK one, and you'd actually need their local Masters.
If you are at all unsure, the international requirement pages on many UK uni websites will state what is required for PG entry, so you can use that to work out what is the same as a UK undergrad.
