Hi Taffy.
The good news is that your JAA Licence is already deemed to be an EASA licence. You only need to visit your local ATO/RTF,(Flying School) and renew your SEP Class Rating. Your old Licence will then be valid again.
Once you have done that, straightaway apply for your Licence to be re-issued as an lifetime EASA PPL. The Flying School will have done lots of these and will help you with the forms.
