They could also re-evaluate the banding and you suffer an increase! A couple of my friends have had dealings with the council tax people
Council tax banding for most houses is very simple, so unless you live in a unique property it is probably correct already, or maybe even too low so keep schtum!
But as you rightly say John, if you live in a fairly standard terraced, semi or detached house and there are lots of them the same in your vicinity, it is well worth appealing if your neighbours are in a lower band
