One example, ....
Those are really examples of what I was suggesting, since they say things along the lines of "A Corgi or Gas Safe service certificate or NICEIC electrical certificate will be required on all gas and electrical equipment within your existing home prior to exchange of contracts to certify it’s safe and in a full working condition".And another,
In other words, the contract is not merely asking for "an EICR", but actually a fairly 'clean' one (i.e. the seller is required to have undertaken any necessary remedial work). Hopefully, that just means "no unaddressed C1s or C2s" but I suppose it's not impossible that they might also expect C3s to have been 'addressed'.
