There is always a sneeky way round the law...
You are allowed to drive your car on a road if you are on the way to get your tax that day...
I drove my car for about a week without tax as I was px-ing my car and did not want to payout for new tax...but to get around that I just carried my papers in the car with me, so if I did get pull I could show them all the paperwork and pretent I was on my way to get my tax that day.

That is if the DVLA stuff does not work out for ya.
