Interval for EICR on private O/H supply

[driverman]

Hi as title, Is there a set time for an EICR say on a Residential caravan site with OH supply. Normally 3 years, but as OH got me thinking. Thanks

If it is a permanent residency site then every three years, if a variable residency then every year, the OH supply should not make a difference.
The problems are more likely to occur where the power is being used.
