Hi Cormac,
I am sure you're aware that UK isn't in EASA anymore. Therefore, depending on where you can move to will depend on where you can work.
Malta is quite flexible but I don't have any info WRT exams and schools. Austrocontrol - bloody expensive either way.
If you have any Irish connections, I'd definitely explore that.
When the UK was still in EASA land, I could SOLI my lic to a Dutch one.
There is "hope" that some common sense will prevail but with Grant Schapps the Transport Minister in the UK, there's not really much chance.
