Enduring power of attorney (EPA) was the system that was in place before LPAs. You can no longer make an EPA. However, if you made an EPA before October 1 2007 and it was correctly filled in, it is still valid and can still be registered and used.
If you have a valid EPA, you don’t necessarily need to make an LPA. However, EPAs only cover decisions about finances and property (like the property and affairs LPA). They do not cover health and welfare decisions, so some people who have a valid EPA might also want to make a health and welfare LPA to cover decisions about their care or treatment.
