Electrical installation testing periods

[Hightower]

I believed until recently that the IEE recommended that electrical installations should be checked on a 5 yearly basis.

Today I came across a sign by an electrician using a 'National Inspection Council for Electrical Installation Contracting' sign that the retest period was 10 years.

Can anyone clarify?

Commercial property 5 years / Domestic (your own house ) 10 Years , however if Housing Trust / Council might put through at 5 years as a let /tenant property.

Thank you for that, most appreciated - are you able to provide a link to the recommendations wherever that may be?  IEE or others?

cheers

I believe there are variations to this as well, though its not my field. Certainly outdoor installations eg caravan sites should be tested annually, and some higher risk industrial premises work to 3 years?

Similar applies to premises that have been zoned in accordance with DSEAR Regs.

Can anyone put any more meat on the bones and correct as necessary?

All set out in the relevant IEE guidance note.

If Colin will tell us which one you could try http://www.theiet.org/publishing/wiring-regulations/updates/

Recommended initial frequencies of inspection of electrical installations are published in Guidance Note 3.

They range from domestic properties at 10years/change of occupancy to construction sites at 3 months.

Generally it is EAWR that requires systems to be maintained as far as is reasonably practicable to prevent danger - so a risk assessment call for the designer I guess

Hi Owen66

I used tw's link and then went to guidance note 3 - gotta say, i was expecting something a little more defined

Is it just me or is there something i'm missing?

The attached link may help a little- see the table down the document

Sorry Hightower, it was useless unless you have the guidance note but at that stage I was trying to establish which guidance note dealt with testing and Owen66 cleared up that point.
