A survey commissioned by the BCI Partnership found that regionally, employees in the capital were the most informed when it comes to business continuity.
A poll of 2,000 workers across the UK found, however, that less than 50 per cent have been told what they should do if their workplace becomes unreachable.
Reasons for being unable to get to work include fires and floods, as well as, in the case of London in particular, terrorist threats.
It also found that just 30 per cent of employees believed their company would survive if they were unable to access their commercial property within six months.
According to nearly 20 per cent, their employers were likely to loose their business within a month if they could not access their offices.
Business continuity was thrown into the forefront for many businesses after the 7/7 bombings on the London Underground when it was clear many had no processes in place for such an event.
