Has anybody heard of the following publication ? : EICR Codebreakers - A guide to coding observations for EICR’s, published by NAPIT. (£16 on a well known commerce site)
I have found several of my recent EICR’s done by different electricians have been referring to this publication to help them choose a C1,C2 or C3 code where there was an element of choice. If you have multiple requirements for EICR compliance it may be worth a look. (together with the Best practice guide No 4 issue 7)
At the end of the day its all about keeping our tenants safe and ensuring we prevent them from living in a death trap property or a fire risk waiting to happen. My example - I looked at buying a house split into 2 flats around 2016, between my viewing the property for 1st and then the second time the plastic Consumer unit burst into flames, spread black sticky and toxic smoke throughout the place and caught the nylon carpet alight below it. A quick thinking neighbour put it all out and found the tenant had been in the shower, Electric, pulling 37 to 47 Amps, at the time. I saw the aftermath. A lucky escape. Exactly the reason we now have metal consumer units since 2015. The CU was in the entrance staircase to the 1st floor flat, above the front door - no escape. Grenfell has further pushed the regulations to tighten.
Electricians do us a good service by highlighting any dangerous elements in our properties installations to avoid the sort of problems above but the subsequent EICR report has to be viewed as a possible future job sheet for said sparky for all the right reasons - minimising danger and risk.
