Equilibrium,
yes I have received my CILOT (quarter council tax) rebates when I have been paid Operational Allowance.
Recently though I received a letter, like a lot of people, that I had been overpaid Op Allowance, i.e. two lots in one day, one for Iraq and one for Afghanistan. Being a tight ar$ed yorkshireman, I decided to check what I had been paid and what I actually needed to pay back, so after a morning going through my log book,pay slips and the rather poor printouts from JPA (several entries for each day), it turns out that they have actually underpaid me by £200. If you've received one of these letters, I'd take the time to check if I was you.
