Energy savings scheme (3)
I believe the answer is:
pep
I believe this is a double definition.
'energy' is the first definition.
(personal energy, vim)
'savings scheme' is the second definition.
(personal equity plan)
(Other definitions for pep that I've seen before include "Energy, zip" , "Palindromic energy or vim" , "Energy or enthusiasm" , "Palindrome for vitality or energy" , "savings plan" .)
