No offence to anyone this might have an impact on, but I'd really like to point out that if you're chimfing about losing £700 quid a year on a posting to Lossie, god help you if you ever get posted to Odiham. Frankly, cost of living change will far, far outweigh the tax!
(I do also appreciate that no one wants a posting to Odiham, but that's bugger all to do with the money!)
