You didn't say what type your're on, but Cockpit4U (division of LH flight training) in Berlin does recurrents for some ME pilots for precisely this reason - I did my own B777 renewal there, with another ME pilot who goes every year to keep his EASA license valid. Don't have to do a full type rating at all, just a 2 hour sim check. Can also do a LST to put just the rating on, if you want. Better do that soon though, while the UK is still EASA. And yes, your rating will then transfer over to an IAA license but you better get on that soon!
Not cheap, but the Germans are absolutely top-notch at taking care of all the regulatory paperwork nonsense. Worth every penny IMO.
And Berlin is a fun weekend, as well!
