The phraseology should have been exactly in line with CAP413 although bear in mind there is a small military specific bit at the back. I can't access it easily at the moment but you should only receive a 'check gear', approaching and passing Decision Height/Altitude calls. Having said that, if you received the latter you were probably being monitored on the PAR. Don't think that you should get an 'over touchdown' call on an ILS though. The controller was almost certainly waiting for you to report ready to switch to tower so that they didn't interupt/distract you on the landing run. In terms of replies, when you're asked 'check gear acknowledge' a simple 'gear down' with your callsign. You don't need to acknowledge the DH calls, they're just advisory. Once you're on the ground and under control, just advise that you're switching to tower and APP will send you on your way.
