It depends, Barb. Let's assume that his disease progresses as expected and he wants to remain at home rather than go into a hospice. The palliative care team (probably from your local hospice) will put a package in place and hand responsibility for his care to the GP and district nurses. If he dies in the night and you don't have a night sitter at the time, you phone the out of hours GP number. Once there has been a home visit to confirm death, you call the undertaker. If he died suddenly before he gets to that stage, you ring 999 and they will send an ambulance and probably the police. If he has died, they then tell you to call an undertaker and arrange to have the body moved. If it is classed as a sudden and unexpected death, the ambulance would take him to the hospital mortuary first and then tell you when the undertaker is allowed to collect him.
