I do EICRs occasionally but charge proper time for it. 4-5 hours av 3 bed or all day plus for larger properties + write up time. There will always be someone cheaper and yes you are competing with organisations/firms who cut corners for a quick buck. I explain to customers that I am thorough and get recommended as such. If they want a cheap report , I walk away. A cheap report can be more costly to the customer in the long run.(sell that one to them) The general public, et all, do not have a clue what is involved, while big companies advertise cheap electrical insurance cover and so called testing.
Don't be put off by the negative reality of it all and give it a go. You never know, you might just turn the tide.
In the meantime, I need to book my van in for an MOT at "BlowMyExhaust & CostyerLots Ltd" for only £3 ....hope it passes ok.
