Adviser commission on auto-enrolment pension schemes established before the Retail Distribution Review (RDR) could be scrapped under measures announced by the government.
A Department for Work and Pensions consultation has asked for industry views on whether in-built adviser commission on pension schemes should end.
It said the Office of Fair Trading raised concerns that schemes containing built-in adviser commissions may continue to be used for current members, as well as being used for people automatically enrolled in the coming years.
The DWP said these commissions may lead to scheme member detriment, because they created barriers to switching between schemes.
The document said: "Advisers can continue to receive commission for current and future members of schemes set up before the introduction of RDR in January 2013.
"There is some anecdotal evidence that there was a spike in sales of GPPs in the months leading up to the introduction of the RDR. If this spike in sales was a rush to set up schemes with commissions to be used for automatic enrolment, this would be a cause for concern.
"We are interested in receiving views on whether commission should be banned and any evidence on the potential impacts of this measure."
The government also plans to extend the consultancy charging back to all defined contribution (DC) pensions, rather than just the current stop on auto-enrolment set ups. Consultancy charges were banned by pensions minister Steve Webb earlier this year.
The document said: "The decision to ban consultancy charges received widespread support in Parliament, among consumer groups, and from the market. However, it is important to protect all savers and not just those in automatic enrolment schemes.
"As such, the Pensions Bill 2013-14, currently before Parliament, contains measures to broaden the existing powers, enabling the ban on consultancy charging to be extended to all qualifying schemes.
"This would mean that consultancy charges agreed before 10 May would have to stop for both new and existing members if the scheme is being used to comply with automatic enrolment duties. We are mindful, however, that these regulations could potentially cause some disruption to pension providers."
The government has set out a range of proposals to limit charges in schemes used for auto-enrolment to either 0.75% or 1%.
Active member discounts - which see deferred pension scheme members charged more than active members - are also under review in the consultation.
