It seems that the Assembly government in Wales is to make hospital car parking free by 2011; though if one looks at the small print some hospital car parks seem to be run by private sector companies on long leases and as such presumably will continue to charge. Elsewhere in the UK Scotland seems set to cap charges at £3 per day. England seems disinclined to follow suit.
I am unsure but I think the here in Northern Ireland the Royal car parking is run by a private company. The Belfast City and Ulster Hospital Dundonald both charge for parking (I think they are in house but I am happy to be corrected). I think the others do not charge. Clearly charging for car parking does raise money which could be spent on hospital services. However, the British Medical Association and Patients Association both oppose it. So will our Health Minister make a similar decision to the Welsh? I suspect it would be popular.
