Dyno Group, which will comprise Dyno-Rod and several subsidiaries, will be formed when founder Jim Zockroll sells to the MBI team for £60.5m and floats on AIM by the end of August.
BP-C&F director Ann-marie Wilkinson will lead the account. Dyno Group will be led by former British Gas home services director Kevin Mahoney. The group has a network of 167 franchises that generated revenues last year of £12m.
The accelerated IPO option has become increasingly popular since Collins Stewart pioneered the approach with Northumbrian Water in 2003.
