As rudestuff says, you can cross credit your MPA IR for the renewal of a SE IR in accordance with FCL Annex 1 Appendix 8. You must have held a single pilot IR previously (this excludes MPL holders). You can fly the procedures with an FI/IRI if you don't hold a rating allowing flight under IFR, eg. an IMC/IR(R).
When you've met the requirements, find an IRE or CRE/IRR to complete the renewal paperwork and post to the NAA for issue.
Provided that within the preceding 12 months the applicants have flown at least three IFR departures and approaches exercising PBN privileges, including at least one RNP APCH approach on an SP class or type of aeroplane in SP operations.
