How long does it take to get ISO certified?

For any single management system including ISO 9001, ISO 14001, ISO 27001, ISO 45001, a typical time frame for implementation is 3-6 months.

Implementation time frames (i.e. building your management system prior to the audit) are as follows:

ISO 9001 – 3 to 6 months
ISO 14001 – 3 to 6 months
ISO 27001 – 3 to 6 months
ISO 45001 – 3 to 6 months
ISO 9001 + ISO 14001 – 4 to 8 months
ISO 9001 + ISO 27001 – 4 to 8 months
ISO 9001 + ISO 14001 + ISO 45001 – 5 to 10 months
ISO 9001 + ISO 14001 + ISO 27001 – 5 to 10 months

This can vary depending on how effective you are at implementing the management system's requirements and the number of certifications being acquired. 

We have completed implementations in shorter time frames however from our experience this means internally you must prioritise the ISO implementation with a central member of staff.

In addition to the timeframes above, you should allow 1-3 months for the certification process (i.e. stage 1 and stage 2 audits) and around 2 further weeks to receive your certificate.

It's beneficial to have the advice of a consultant when doing this but you can do it alone if you have the time and resource needed to learn the standard and its requirements.
