Hello TC,
No 109s flying regular emergency services in the UK. There will/may be occasional charter EMS no doubt.
Dyfed-Powys Police [they suffered a crash recenty] have yet to make a decision on what to replace their own 109 with so it is a mite too early to write the type off.
The 109/119 [Koala] remain popular in the world emergency services arena of course - mainly EMS.
