Can private investigators look through people's rubbish?

[R2D2]

In the United Kingdom, private investigators are subject to laws and regulations defined by the Regulatory and Investigatory Powers Act 2000 (RIPA) and the Data Protection Act 2018. According to these laws, it is generally not permissible for private investigators to engage in activities such as searching through someone's rubbish without a lawful and legitimate reason. Under specific circumstances, such as when authorized by the relevant authorities, for a specific investigation, or when the activity is considered reasonable and proportional in the interest of public safety, private investigators may be granted certain exemptions. However, unauthorised searching through someone's rubbish would generally be seen as an invasion of privacy and a potential breach of the law.
