If it's more than a year since you did the course the minimum retraining requirement will be an APC (i.e. back to CATC for a week); if it's more than five years you'll almost certainly have to do the rating course again.
The former is causing us all sorts of problems with folks who do their radar validation first. We can do a radar APC locally, TWR can only be done at the college (some of the bigger units may be able to do it in-house if they have ADC simulators).
I suspect that SRG will not allow controllers to hold validations at two units any more either - I know a couple of London guys who used to do Wycombe Air Park on the side are no longer able to!
