SurelY the proble here is that if you had a accident and you were say "delivering sandwiches" or were window cleaning on a standard insurance policy, then your insurance company would say it was void as you weren't insured for that purpose?
And so in that case the police can say you have an invalid policy. Your not insured to use this vehicle for work.
Or is it a case of the police can't and have to prove it?
Sounds to me like one of these "don't pay your water bill" things as nothing actually happens to you if you stop.
Keep it simple. Pay what's due, pay your taxes, live without the worry of having to go to court for something that would have only cost you a few quid a month in the first place.
Police can prove it without even approaching you its all on their database, Cleanclear is right by law all you need is third party
insurance.
They will need to prove that you are using the vehicle for business use but if your carrying cleaning equipment and you say
that its for personal use well it wont be hard for them to suss out the truth.
But as we all know by not declaring certain facts you can render that insurance void, that's the whole insurance not just
the comprehensive part.
So in other words you wont be insured for anything.
