Investment platform Skandia has taken on temporary staff to deal with an estimated "ten-fold" increase in workload following the administration of Honister Capital.
The Honister collapse has led to delays in processing times, as advisers contact the provider to set up new agencies and transfer clients.
Informed Choice director Martin Bamford said he was quoted 25 days to process a letter of authority to Skandia Investment Solutions.
The firm had been "overwhelmed" by transfer of agency requests, which have been held up by Honister administrator Grant Thornton, he said.
"The floodgates have opened and [Skandia] was talking about ten times the volume [of work]," he said.
"The transfer we are having the delay on was an ex-Honister IFA who we have taken clients off."
A Skandia spokesperson said a ten-fold increase was "a rough guess" to give advisers an idea of the scale of the challenge, but confirmed the provider had taken on extra staff to deal with the increase.
"Volumes of enquiries are up significantly as a result of Honister going into administration, and we have taken on temporary staff to help advisers with transfers of agencies, setting up new agencies and bulk transfers of client," he said.
"Honister was obviously a huge network so there are loads of advisers out there that have clients with Skandia that need our help.
"We are doing everything we can to process it as soon as possible for them hence taking on temporary staff."
Grant Thornton has since sold the Honister trail commission book to corporate adviser MacRobins.
