To be honest, I’m planning on a career change and am in the process of arranging my provisional licence so as to begin LGV training. But as I’m likely to become a regular here I doubt this will be my first and last piece of advice.
As an addendum though, if you over-provide with a provision say provide for £14,000 and then your cash expenses actually amount to £5,000 then the over provision of £9,000 will be taxable in the following year.
