as someone who used to have renal failure and may yet have to return to a kidney machine i am making enquries about this. my understanding is that if it is not exempt it is a farce cos costs nhs over a £1k to install the costly plumbing for a mains water supply to run a machine means it cannot be a "bedroom"- more like a second bathroom. it cannot be spare cos every other day the patient has to be connected up to it for at least 5 hours each session so it can never be used by anyone to use as a bedroom social landlords may well allow the machine's installation as tenant has some security of tenure. private landlords would be very unlikey to allow- tenant has usually only 6 months security of tenure- this is what the government expects the tenant to do- move to private sector. DDA claim?.
