I have indeed discovered Deeside Flight Simulators and I have booked an MCCI course with them next year.
Having dredged through the regulations my current take (I’m not a legal expert so do your own research if this affects you) is:
When you have been issued with your MCCI certificate you are restricted to the device you did the course on.
If you want instruct on different device for the SAME TYPE (eg A320), you can undergo standardisation by the ATO with the new device, it is an internal matter. No variation is required and no fee is payable to the CAA. That ATO does not have to be MCCI course approved.
If you want instruct on a different device for a DIFFERENT TYPE (egg add 737 privileges to an MCCI with 320 privileges) then the practical training element of the MCCI course must be carried out on the new device, a variation is required, the forms must be filed with the CAA and a fee paid. That ATO has to be MCCI course approved as the have to sign the MCCI course completion forms.
So my current plan is to get the MCCI certificate (on a 320) and be standardised by an ATO with a 320 FSTD locally. The reason for this is that the ATO I have in mind don’t plan to get MCCI course approval, otherwise I would have done it with them.
Thanks folks for your input.
