Please note that there is no one curriculum across the United Kingdom.
Each country has its own system. However, the systems across England, Wales and Northern Ireland have much in common, for example using similar terminology.
Scotland does not have a national curriculum, as England does. The link above is therefore to the "5 to 14" guidance given to schools.
The Curriculum for Excellence in Scotland is a different kind of curriculum, providing guidance on how to teach, rather than stating what to teach.
