Electrical testing is already a legislative requirement. The frequency is determined by the responsible person / owner of the installation based on the management of the installation. I know its not as clear cut as gas but that just means people like you and me need to educate the decision makers in our organisations so they understand.
I totally agree that a standard frequency should be sought for those who don’t manage their installations as well as they should but believe Value for Money can only ever be achieved in Electrical installations by managing them better.
There is so much more we can do that would be far more effective than a standard frequency. The AESM is a great platform to drive these new ways of working forward for all members to benefit.
