The South Coast-based distributor received £25.2m in new applications in June, achieving £17.6m in offers.
Tony Salentino, director of Complete FS, said: “This has been our best month since 2008 and I think I can now safely say that the industry has recovered a lot of the ground it lost when the credit crunch hit in 2008.
“Complete FS has probably the longest pedigree of consistent support for the intermediary market as we mark our first 21 years of service this year.
“Complete’s history is one of innovation and improvement and we are looking forward to announcing further enhancements to our already legendary service over the next few weeks.
“We are delighted by the volumes we are now handling and while there still might be some bumps in the road as the overall economy continues to improve, Complete FS is looking forward to the rest of the year as more introducers are becoming aware of how Complete FS can help them.”
