To be clear on the above points... First you (in theory) can't, from the viewpoint of the scheme go around doing EICR without their assessing your competency and stating that as a specific competency above and beyond DI. Now I know, before you all go off half cocked, that you can do EICR til you're blue in the face and there is no legal reason why not! Don't forget though, you have to have PI insurance. Having said that most schemes will grade your membership according to their criteria and perceived view of your skills on an evidential basis. If you have a schemes "badge" you are competent for EICR it will stand you better in the public's eyes as against just going out on your own because you believe you can do it, which admittedly you may just be so skilled! The point I am making is that Landlords will be looking at NAPIT rather than so much STROMA for lists of sparks who are accredited to do this. The legislation does state the electrician offering the service must be competent/experienced and this is going to be a thing for us to show. The industry has jockeyed us (herded?) into joining into this. And why not, it is good for business and for me a £120 is a drop in the ocean compared to the work I envisage arising from the investment. As to is this an add-on yes it is. However it seems 2021 is the crunch year where we will be having to go NAPIT or hit the highway, and pay their prices (ouch!) no more STROMA price structure. So why not use this to our advantage?
