Question to the Home Office:

To ask the Secretary of State for the Home Department, how many illegal working investigations have been opened into parcel delivery firms in each of the last five years; and how many resulted in (a) civil penalties and (b) prosecutions.

The Home Office does not hold data on illegal working investigations at the level of detail requested. For civil penalties, illegal working enforcement activity is recorded by employment sector, not by specific sub sectors such as parcel delivery firms. For prosecution, criminal investigations relating to illegal working will be recorded in line with the primary offence under investigation, such as possession of a counterfeit identity document, or assisting unlawful immigration. As a result, we are unable to provide figures on the number of investigations opened into parcel delivery firms or the outcomes in terms of civil penalties or prosecutions.

Any relevant activity would be captured under the broader business sectors of Warehousing, Distribution and Delivery or the primary offence under investigation.

A breakdown of activity by sector is available in the Home Office publication which can be accessed at: Illegal working and enforcement activity to the end of December 2025: by illegal working sector - GOV.UK
