Send Clowns - not quite my friend ref JAR-FCL 1.016 'the authority may be guided as to the credits to be granted on the basis of a recommendation from an appropriate FTO'. It's up to each individual authority to grant credits as they see fit.
James - providing you have over 100 hours multi the MEP consists of a quick licencing proficiency check which should be completed within the required training (during the 170A for example).
I did the flying with Tayflite in Perth (Scotland). Couldn't have asked for a better bunch of people. Nicely maintained PA34-200T's at reasonable rates. FNPT II sim onsite. Accommodation and a bar at the airport. Examiner on the field. The owner (Les) is a great guy and has some pretty practical views on flying. My instructor (thanks Richard!!) had flown in Africa, US and the UK so was very helpful in pointing out the differences in the UK procedures (which is really the only problem you should have during the process).
Hope this helps.
