Brookson, a firm with 300 employees, acquired 1st Option earlier this week. The Financial Conduct Authority (FCA) has authorised the deal.
The firm said that the acquisition will allow the development of its services to customers, increase its industry sector spread and strengthen its position in the market.
Martin Hesketh, chief executive of Brookson said, “We have been searching the market for a suitable business to enable us to expand our services while also enhancing our strong reputation and heritage.
“We have found this with 1st Option who provide a range and standard of service that will complement that already offered by Brookson.”
Brookson plans to continue acquiring firms this year in a bid to strengthen its service offering to customers, it said.
1st Option is an accounting firm for freelancers, contractors and interims.
David Mount, managing director of 1st Option, said, “Since 1996 1st Option has built a reputation for providing excellent customer service and professional financial advice and I am very proud of the hard work and dedication my staff have shown over the years.
“Brookson provides an excellent home for the 1st Option business to develop further to support our customers in the future.”
The firm added that the 1st Option brand and existing service experience for customers will continue following the merger.
A spokesperson said, "In delivering this, we expect to retain a presence in Coventry but we will also integrate some roles into our operations in Warrington."
