Private detectives to need licence 31 July 2013 Last updated at 15:55 Operating as an unlicensed private detective is to be illegal in England and Wales, the home secretary has said. The Home Office said it wanted to "ensure rigorous standards" in an industry where "rogue investigators" had been infringing privacy. Those who break the new rules - to be rolled out from autumn 2014 - could face up to six months in jail. MPs earlier said police had linked 100 firms or individuals to investigators who had obtained information illegally. Blagging Anyone can currently set themselves up as a private investigator, regardless of their skills or even criminal convictions. But under the Home Office's plans, investigators will be licensed by the Security Industry Authority after completing a training course and passing a criminality check. The new regulations do not extend to investigations carried out in relation to publishing legitimate journalism. Home Secretary Theresa May said: "It is vital we have proper regulation of private investigators to ensure rigorous standards in this sector and the respect of individuals' rights to privacy. That is why I am announcing today the government's intention to regulate this industry, making it a criminal offence to operate as a private investigator without a licence. Anyone with a criminal conviction for data protection offences can expect to have their application for a licence refused. Firms could be barred from being licensed if they have been involved in offences including: Unlawful interception of communications, such as phone hacking Accessing data on computers without permission Gathering personal details by posing as someone else, such as blagging information from a call centre Bribery The Home Office said that all contractors would need to be licensed and the maximum penalty for failing to comply with the new rules would be six months in jail. In the shadows Tony Imossi, president of industry body the Association of British Investigators said the proposals were a "good start" but did not go far enough. The government's long-awaited decision to regulate private investigators will go some way towards controlling who carries out private investigation work. But the question is - will it help define the line, often blurred in practice, between what is legal and illegal? Even the so-called "blue-chip" clients of PI firms say it can be hard to ensure the information they ask for has been legally gathered. Sometimes PIs use illegal methods to track down the information they need - and then apply legally to obtain it. But it's unlikely regulation will quell the current accusation that not enough has been done to investigate clients known to have commissioned rogue private investigators. Settling old scores, some in the media see this as a case of double standards in which law enforcers went after media phone hackers but not corporate commissioners of private eyes. Publishing the list of clients who used the Operation Millipede PIs would help establish who was using investigators and why. But Soca and the police remain resolutely opposed. The move was welcomed as a "positive step" towards protecting people from unwanted surveillance by privacy campaigners. "For too long private investigators have been allowed to operate in the shadows," Big Brother Watch director Nick Pickles said. It comes as pressure mounts on the Serious Organised Crime Agency (Soca) to release the names of more than 100 companies and individuals potentially linked to rogue private investigators who were convicted of obtaining information illegally. The Home Affairs Select Committee has published a breakdown by business sector of clients linked to the jailed investigators, but has not named them individually. Chairman Keith Vaz said the identities of the firms and individuals had been held back from the report so as not to "compromise" any investigations by the police or information commissioner. Eight of the clients on the list were used as evidence in prosecutions under Operation Millipede, an investigation that led to the conviction of four private detectives for fraud last year. A further 94 were judged as potentially relevant to the case, but not used as evidence. "When we publish our report into private investigators, we would like to be in a position where we publish the entire list," the Labour MP added. Meanwhile Nick Clegg, the deputy prime minister, said: "I have a lot of sympathy with those who say, if there are big companies and organisations that are using private investigators to find information about individuals and organisations, they should be open about it." The clients include 22 law firms, financial services and insurance firms, accountants and two celebrities.
