If there is a UK need for such Civ SAR support why doesn't the respective Gov't Dept pay for it
I would suggest HM Coastguard would be a suitable candidate. But it is underfinanced and relies on a lot of volunteers as does the RNLI.
Why is it this country expects essential services to be run as charity cases?
Oh of course the money gets spent on all the non essential welfare services for those that will not try to look after themselves, or those that decide to come here to be cared for by the State.
( And before I start a riot , I am not including those that are in real need of support)
