There is no straightforward answer to this question as it depends on the size and complexity of your organisation, what systems and processes are already in place and what resources are available.  

However, in URM’s experience it typically takes between 6 and 9 months for a small, low complexity organisation to fully implement ISO 27001.  

With larger, more complex environments, 9 to 18 months is closer to the norm for fully establishing an ISMS. This naturally assumes that the appropriate resources are made available to achieve the desired outcomes.

We have just received the CE+ certificate and notification that we have passed; we wanted to thank our assessor for all his help with this. It is greatly appreciated. I know that our team is very grateful as they were expecting the process to be difficult. Instead of being difficult, URM’s assessor made it a smooth process and we have all learned a lot
