If I was selling a place and a potential buyer wanted an EICR done on their instruction and payment I would only consent on the condition that I had a copy of the report at the time it was done. I certainly expect anything that anything dangerous was reported to me ASAP in order to rectify and any other issues could then be factored into the price negotiation. I’d take exception to a last second ambush in order to get a price reduction. Easy to say, I know, as it depends on the amount of reduction being asked and how much the sale is needed, other parties in chain etc. Moral of story, get your own EICR done early days to save any surprises.
