Powers of investigators

Investigative authorities

There are number of investigative authorities who have varying powers under which they can carry out raids, conduct searches and seizure of property and require individuals to attend interviews or to provide information or documentation as part of their investigation. These authorities often have memorandums of understanding in place to ensure they can work together when investigating criminal offences (see Practice Note: Memorandum of understanding—criminal investigations and prosecutions).

For a quick guide to the relevant authorities and the scope of their powers, see Practice Note: Dawn raid—table of relevant authorities and the scope of their powers.

Below are some useful links to Practice Notes which provide information and guidance on how to deal with the individual authorities, in particular what to do when they come knocking at dawn, and setting out their relevant investigative powers.

Independent Anti-Slavery Commissioner publishes model forced labour legislation

The Independent Anti-Slavery Commissioner has published model legislative drafting proposing new UK forced labour legislation for adoption in the next King's Speech. The proposed legislation would introduce liability for organisations failing to prevent serious human rights harms where reasonable preventive measures have not been taken. It would grant government powers to ban products made with forced labour from entering the UK and restrict imports from high-risk regions. The Commissioner's report, published on 16 December 2025 in partnership with Omnia Strategy LLP and Unseen, identifies that the UK imports approximately £20bn worth of goods annually at risk of being produced through forced labour. The proposal aims to align UK law with international partners including the US and EU, which have introduced similar measures to prevent forced labour goods entering their markets.
