I wish you luck, but fear you not get far.
This has been looked at on several occasions and has always drawn a blank. The reason? the good old X-factor. And like it or not, that is what you will be told by those in high places.
My sqn and I looked into this matter several years ago, when we were spending 8 - 9 months out of the country each year in Bosnia and Kosovo. My particular winge was regarding Car Tax and Car insurance and I spoke to HMG and my insurance co' about these very two points, pointing out that as I couldn't use my vehicle, can I have a rebate of sorts?
The answer from HMG was ''Don't you get the x-factor to cover these sorts of things?' and the reply from my insurance co' was slightly more disturbing in that that they were considering 'loading' me because of my lack of regular driving experience in the UK!! (I didn't pursue either!)
Good luck tho' and I'll gladly liobby my MP for you.
Kind regards
