Some companies may decide that one specific Standard meets their requirements, both internal and external. Others may determine that there are advantages to gaining more than one Standard. We have many clients who have established the advantages to them of being certified to both ISO 9001:2015 – Quality - and ISO 14001:2015 – Environmental. Some go further and achieve certification to ISO 45001:2018 – Health & Safety too. In addition, there might be cost benefits as some Standards have some overlapping requirements.
