From Monday 1st October, it will be an offence to clamp, tow or immobilise a vehicle without lawful authority.
The SIA Vehicle Immobilisation licence will therefore no longer be valid in England and Wales. Licences will continue to be valid, and issued by the SIA, for use in Northern Ireland.
A Home Office fact sheet on the changes can be viewed on its website.
Vehicle immobilisation is already considered unlawful in Scotland and has therefore never been subject to SIA licensing.
