Can you replace just the RCD, instead of whole consumer unit?

My apartment failed it's EICR due to the electrician not being able to trip the RCD in the required time.  I am told that the RCD cannot be replaced and a new metal consumer unit must be installed at a quote of £1180.  The apartment was built in 2003 and seems overly wasteful to ditch the whole unit, however I am not an electrician so would welcome some guidance please before I commit to this remedial action.


This is the RCD currently fitted:
5760S | MK 63 A RCD Switch, Trip Sensitivity 30mA | RS Components (rs-online.com)


It appears it worked within spec for above 30mA, but failed for below, if that helps with whether the whole consumer unit must be replaced.  See report.

    What a waste of time that report is. Out of 13 circuits there are only 10 actual test results recorded on the sheet. I would definitely be asking for my money back as he tested nothing, and didn't spend any time looking for circuits, despite the board being quite well labelled up. Typical example of how the EICR has been used for job creation, he had already decided to replace the board before he even got out of the van
