Although Legacy is produced in America, it is also designed to work very well for UK data entry and research. First, you can select to use the UK-English, where all phrases and word spellings are automatically adjusted for the UK. There are also a number of historical timelines to use with the Chronology View. The Research Guidance section is very good for UK research, which provides guidance and suggestions for actually performing UK research - Scotland, Ireland, England, Wales. There are also blank England census forms that can be printed and filled in.
The "UK version" is part of the main Legacy program. When you install Legacy for the first time, you can select which language you wish to use, one of them being "English - United Kingdom". Legacy contains all sorts of UK resources for the Research Guidance and we're adding more UK related templates for the SourceWriter all the time.
