Three weeks ago I found 'abandoned vehicle' notices on three of my vehicles parked in the privately owned back alley, the notices gave me fifteen days to move them or they would be towed and crushed (at my expense!) Two days later I got FPNs in the post for £200 each vehicle. I wrote to the council and pointed out the obvious: private land: it doesn't matter, the council can take action against what they consider abandoned vehicles anywhere !! (refuse disposal act 1978)
I moved the vehicles anyway (drove them away, so that shows how abandoned they were!) Told the council they were gone, and asked for the fines to be revoked, I was polite and pointed out the inaccuracies in their 'evidence'
A week went by and they have agreed to drop it.
So, if, like me, you have a camper van (or vans, or cars) that have not moved in a while, BEWARE. My vehicles were sorned and insured.
What a good job I was here and not on holiday, or I would have come home to a very hefty bill and no vehicles or their contents.
