You are right on the record keeping especially if there is a chance of standing in front of the judge.
We have the problem here that a ward says There was a problem with a piece of equipment while it was on a patient. They raise an incident report and send it off to risk. Now they get around to telling us we test it and find it good/bad but there is no link to the incident. The powers that be have been told and have done sod all about it.
As for the training records we maintain them as education was tasked and has so far lost everyones record in the trust. Lucky for our backups. (certs in a folder). They are now asking everyone if they have done their health and safety, so far it looks like everyones up to date

I dont agree with the VRCT in that the name gives it away (Voluntary). How are you going to defend yourself in court if you dont employ someone not in the voluntary register. If your driving licence was voluntary would you pay for one?
Keep your records up to date as there is no support when the proverbial hits the fan. That includes all the emails highlighting the problem.
