Was at my preferred CVRT test Centre in Wicklow town this morning with Daisy.
Cannot recommend the place highly enough
Whilst there I saw this notice.
For €50 + VAT they'll do a Voluntary CVRT test, ie a test without the Certificate so you know the current state of your MH. Can be done at anytime before the CVRT expiry.
It would be great as a pre test so any issues won't show up as advisories of fails and also for peace of mind when selling. Not every test centre does this but check in advance and tell them it's a Voluntary Test.
