 This made Irwin Mitchell the nineteenth law firm to convert to an alternative business structure, and the first to do so under a “multi-licence”.Following the approval of the alternative business structure, the firm continued its expansion with a string of acquisitions and office launches over the next three years.This growth was financed in part by a £60m finance package that was announced in 2014, funded by HSBC, Lloyds Bank and Royal Bank of Scotland.
