It is a criminal offence to clamp/block/tow away a vehicle on private land without lawful authority. Lawful authority to immobilise or move a vehicle is restricted to a number of organisation such as the police, DVLA and local authorities.
Privately owned land includes car parks, such as those at retail parks, whether or not there a fee is payable in order to park there (not local authority run car parks).
To commit this offence a person must intend to prevent the owner/driver from moving their vehicle. Therefore, clamping your own car to prevent theft would not be an offence. No offence would be committed where a driver was prevented from leaving a car park because the vehicle's exit was blocked by a fixed barrier.
Clamping of a vehicle on a public highway can only be done by public bodies, namely; a local authority, the police or the DVLA. Normally vehicles are only clamped on a public highway if the vehicle has no excise licence, parked in no waiting or other restricted area (eg permit holders only).
