Hello Dyer
Not sure exactly what you need to do, as I believe it does vary depending on your experience level. I suggest that you have a word with the FTO that I trained at; Flightpass, down at Exeter, in the South West of the UK.
They had a guy converting his FAA IR when I was on course last year, so I know that they do them. I did my JAR MEP/IR with them and I was very pleased with the training and facilities etc.
01392 444740 is their number.
Good luck.
