Niche PPI broker British Insurance, run by Simon Burgess, could be sold within the next two months.
The business, which was put up for sale last month, has created a shortlist of six potential suitors, including a major European investment bank.
"There has been a great deal of interest and we are looking to have it wrapped up in the next couple of months," said Burgess, who could net up to £25m in a sale.
"We are a small, niche fish in a very big sea of PPI which has £5bn a year in commissions. It is a significant market with huge opportunities."
If a European investment bank were to buy the company, it would further indicate how brokers are attractive purchase prospects for foreign entities wanting to break into the lucrative UK insurance market.
