Scammers are cold-calling people about personal injury claims and pretending to be from the Association of British Insurers (ABI), the trade association has warned.
The ABI said it has been contacted by people who have reported receiving cold calls from those purporting to have some sort of connection with the ABI.
Fraudsters are trying to encourage people to make fake claims, it said.
It said it would never contact people in this way about a personal injury claim or endorse a claims management firm.
ABI spokesman Anthony Wright said: "Any cold callers saying they are connected with the ABI are cowboys trying to scam honest people into making a fake claim.
"We want the public to know that the Association of British Insurers will never contact members of the public in this way and does not endorse any claims management firm.
"If someone does contact you about a personal injury claim saying they work with the ABI, our advice is to just put the phone down."
Nuisance calls and texts can be reported to the Information Commissioner's Office.
