I agree with Roy. There should be a grace period, perhaps 14 days, to get meters reprogrammed. It's ridiculous that men should be deemed to be operating illegally for charging the old rate shortly after a rate change.
There are problems with Applus+. There were no appointments available anywhere in the country when I rang last Monday. When they rang me back on Tuesday they could only offer me centres on the southside of Dublin. When SGS had the contract appointments were readily available nationwide back when they had 20,000 more drivers to deal with. I know other drivers who, like me, have been given appointments miles away from their nearest test centre and who, like me, have no intention of driving that distance so will reschedule within 48 hours of their appointments and will continue to do so until they are presented with a reasonable option.
