The only secure way to echo the content of a variable is to use the delayed expansion here.
If percent expansion is used, it depends on the content if it fails. 

set "var1=Hello ^& World"
set "var2=Hello & World"
setlocal EnableDelayedExpansion
echo !var1!
echo !var2!
echo %var1%
echo %var2% -- fails

The delayed expansion is more usefull as it doesn't interpret any special characters.

just

echo Hello ^& World!

works

EDIT so the problem is not with ECHO command, but with the assignment of the variable, as @Bali correctly pointed out.

This works for me:

set "hi=Hello^&World!"
echo %hi%

Outputs

Hello&World!
