Insurance requirement for 3phase competence for a single phase building

I've just taken over the running of a community building which is single phase and is no more complex than a large 4-bedroomed bungalow in terms of space, load and number of socket outlets. The electrical test electrician currently conducting the test is qualified for single phase only. The new insurance company specifies the tester must be qualified for 3-phase. While they have a right to do this, is it reasonable and based upon a real need? Can I contest it and on what technical basis?

  • Just on a slightly different note, Council here will only accept Emergency Lighting Periodic Inspection and Test Certificates from NICEIC or equivalent. I don’t think the scheme providers assess competence in the area of emergency lighting unless defined approval.

    In the OP, I reckon the insurance company don’t want a domestic spark doing the 3phase inspection. 
    Competence is being scrutinised in every area of our industry, perhaps rightly so. However, competence for a particular task is often an elusive consideration.
