Technically you can be fined for driving it without an MOT unless you have a pre booked MOT appointment and are driving it there, as Al mentioned. No points though and it is quite a small fine - £60. I got fined that taking my last mig to the scrap yard
. I'm pretty sure you won't be fined if it is just left on a road, insured and taxed.
Pumbien v Vines
(1995) The Times June 14 Queen's Bench Divisional Court
A motor car parked on a road was being used on the road for the purposes of sections 47 and 143 of the Road Traffic Act 1988 even if it was totally immobilised and could only be moved by being dragged away, and, therefore, required both a valid MOT certificate and an insurance policy.
The Court so held in dismissing an appeal by way of case stated by Andee Pumbien against his conviction of offences of using a motor vehicle on a road without either a valid test certificate or insurance policy contrary to sections 47(1) and 143(1) of the 1988 act.

Also potential insurance issues with no MOT
