The rules on unregulated introducers should be tightened, he added, as they are often the link between consumers and bogus investments or pension schemes.
Contractually linking introducers to authorised IFAs or pension schemes would see them required to comply with Financial Conduct Authority rules, Mr Wilson said, and stem the flow of customers to risky schemes.
"We are also pressing for the government to carry out an assessment of the impact of an outright ban on cold calling related to regulated financial products.
"Referral fees between introducers and pension schemes should also be fully disclosed or banned altogether, as they are between claims management companies and solicitors."
Alan Chan, director at IFS Wealth & Pensions said providers have a "very important role to play" as part of the public’s "front line defence against scams".
He wanted providers to actively encourage people to use the FCA’s adviser directory to check if they are dealing with a legitimate firm.
"I think the FCA could do more to educate people about regulated advisers and create more awareness that there are ‘unregulated advisers’ too and they need to be careful when they are approached by them."
Diligent advisers will ask the right questions to identify if their client is subject to a pension scam, he said.
"These situations are rare because the nature of an adviser-client relationship is such that they would normally consult their adviser first before acting on anything they hear or read from somewhere else.
"It’s more likely that a customer who does not already use a regulated financial adviser, or, worse, cannot tell the difference between a regulated and unregulated one, is the victim of a scam."
