It is worth stating plainly, because a surprising number of people still do not know: clamping a vehicle on private land is, in almost all circumstances, a criminal offence. It has been since October 2012, when section 54 of the Protection of Freedoms Act 2012 came into force. The old private clamping industry - the van that prowled retail parks with a boot and a payment terminal - was legislated out of existence, and what replaced it matters to fleet operators in both directions: your drivers cannot be clamped on private land, and you cannot clamp trespassers on yours.
A person commits an offence who, without lawful authority, immobilises a motor vehicle by attaching an immobilising device to it, or moves, or restricts the movement of, a vehicle by any means. Read that second limb carefully: it is not just the yellow triangle on the wheel. Blocking a vehicle in with another vehicle, chaining it, or otherwise preventing it from leaving catches the same offence. When the ban was announced the government confirmed it extends to towing away and all other forms of immobilisation on private land without specific legal authority.
The penalties are real: on conviction on indictment, an unlimited fine; on summary conviction, a fine up to the statutory maximum. And there is a carve-out only where a person is entitled to remove the vehicle - lawful authority holders such as the police, local authorities and DVLA operating under their own statutory powers. The ordinary landowner has no such authority.
A truck, van or car parked on private land - a supermarket car park, a private estate road, a customer’s overflow yard - cannot lawfully be clamped or towed by a private operator. What private landowners can do is issue parking charge notices: the civil, ticket-on-the-windscreen regime that replaced clamping. Those charges are contractual claims, not criminal fines, and they follow their own dispute processes. The fleet administration point is to know the difference on sight: a clamp on the wheel on private land is evidence of a crime in progress and a call to the police; a ticket on the windscreen is paperwork to process.
Drivers should be briefed: never pay a clamper on private land, never be intimidated into a “release fee”, and call the police if a vehicle is physically prevented from moving. Equally, parking charge notices should still be handled promptly - they are enforceable civil claims and ignoring them is how small sums become court claims against the keeper.
The other direction catches operators out. The yard with the persistent trespass problem, the depot entrance blocked by commuters’ cars, the HGV parking area full of unauthorised vehicles: the temptation to clamp or block in is understandable and entirely unlawful. A transport business that clamps a trespasser’s car has committed the same offence as the old cowboy clampers, with the unlimited fine exposure and, for O-licence holders, a conduct matter that can travel upward.
Lawful tools for managing private land exist and should be used instead:
None of these immobilises anyone. All of them are legal.
One confusion worth clearing: the clamping ban did not affect the statutory powers of councils and the DVLA. Authorities removing abandoned vehicles, clamping untaxed vehicles, or enforcing parking on the public road operate under their own legislation with lawful authority - section 54 is aimed at private actors. So the untaxed van on the street can still be clamped by DVLA’s contractors while the same van in your yard cannot be clamped by you. The distinction is authority, not location.
Section 54 is short and absolute: no lawful authority, no immobilisation, no moving, no restricting - on pain of criminal conviction. Brief your drivers that they cannot be clamped on private land, brief your yard managers that they cannot clamp anyone else, and build your site parking control on signage, charges and access management instead. The era of the private boot ended in 2012; operating as if it did not is a criminal-law risk sitting inside an otherwise compliant business.
