'Might be worth noting that because this sort of thing isn't an NHS function, provision varies between the different nations of the UK.'

... & even between different Health Authorities. When my late wife had difficulties caused by her Parkinsons disease, the local [Cambs] *District Nursing* service were wonderful, two of them coming round to assess her needs, then sending a man round within 48 hours to fit a bath-shower stool [we already had handles as they came with our bath, otherwise they assured us they would have been provided also], handles for in/out of bed, &c.; they also carefully checked that we had such necessities as a dimpled rubber shower-mat.   After she died, a single phone call brought another man to come & take them all out again.

So it seems that Lizzie is unfortunate in that Cornwall is not so well furnished with such services. What experiences have those under other health authorities had?
