is this a bad business practice for an electrical company?

a little background here, our home is a newly refurbished home in 2017 and it passed all the electrical inspection when we buy the home. Recently we've got a new contractor to do an EICR for us. Then here are the issues, they came and did the inspection, after 2 weeks, they only sent us a second quote and didn’t give us any report nor mentioning any coding (c1,c2,c3) nor anything unsatisfactory. When I ask for the EICR report, they told me that the certificate will be given after completing the work on the second quote and which needs to be carried out within 28 days otherwise we could be fined a lot of money from the council…… THAT'S FRIGHTENING!


But from what I known, I don’t think the work on the list is mandatory and some of them not even electrical related (see the attached invoice)… At this point, I don’t know what was going wrong as it does not mention anything that is unsatisfactory and I certainly not sure the total £672 is correct.


Discussion:

- Is this a bad business practice? 

- Are the work listed are mandatory before giving the EICR?

- What should I do next?
