The KPMG survey found that while the majority of British business chiefs were confident of both their own company's and the UK's growth prospects over the next three years, 76 percent said they were considering moving their headquarters out of Britain following the June 23 Brexit vote.
"CEOs are reacting to the prevailing uncertainty with contingency planning," said Simon Collins, KPMG UK chairman.
"Over half believe the UK's ability to do business will be disrupted once we Brexit and therefore, for many CEOs, it is important that they plan different scenarios to hedge against future disruption."
Concerns Over Post-Brexit Business
The survey's findings show the increasing concern over Britain's post-Brexit economic landscape, with the UK government yet to announce what type of trade agreement it would like to negotiate with the EU.
There are concerns among the UK's business community that any attempts to severely restrict EU immigration may lead to the UK being locked out of the European single market, which some critics say could be devastating for the British economy.
