PPI claims firms make up half of nuisance calls Ofcom is currently working with the Information Commissioner's Office and the Claims Management Regulator, part of the Ministry of Justice, to tackle the issue of nuisance phone calls. Ofcom has a track record of success in this area, last month concluding an investigation which saw telecommunications company TalkTalk fined £750,000. Last year emergency insurance company Homeserve was issued with a similar fine. Which? executive director Richard Lloyd welcomed the three regulators coming together to tackle the problem of nuisance calls. "Today we see three of the regulators starting to step up and respond to the public outcry, with the Office of Fair Trading and the Information Commissioner also getting a grip on how companies collect and use consumers' personal details, data that is sold on to third parties and used to generate unsolicited calls and texts," he said "They must use this intelligence and get tough when they find the rules have been broken by hitting those responsible with heavy fines. Mr Lloyd said that the time had come to call time on nuisance calls and texts. He added: "We want all the regulators to work together in a concentrated effort to properly police firms that are part of the problem and to take tough enforcement action, which is why we've called for a joint task force."
