Just to update. After speaking with dvla today she told me I could drive under section 88 as mentioned earlier. Ive just rang motability there with not really finding anything online to clarify and when I told her that dvla told me I could drive under section 88 she said that when I collect my car and sign documents with pin number to them, just ring them and they can add me on to policy for 30 days.
I hope this helps.
