Hello,
If it helps, my grandfather died at Westminster House in 1949. So, I've been down this road & asked all the same question you're asking now. I found the following info:
Westminster House was originally the Kirkdale Industrial Schools for children from Liverpool Workhouse. It was later converted into an old people's home. It closed in March 1968. The newspaper of the time listed it as "the largest old people's home in the country" It was run by Liverpool Health Committee.
Although Walton Hospital had a padded room in G Ward it was never used, certainly not after 1910, because lunatics (as they were called then) were transferred to Mill Road Hospital. By 1930 Mill Road closed that section and all mental patients sent to Smithdown Road. Belmont Road took female patients with senile dementia and Westminster House took the male patients with dementia. So Westminster House was one of the very early homes for the aged with dementia & probably also generally elderly people who didn't have dementia, but had nobody to look after them & couldn't cope alone. God bless them it sounded awful.
My grandfather's DC said the same: "No fixed abode" This confused me, as when I got the Westminster House records from LRO (£20) it gave NOK as his daughter & he lived with his daughter before he was admitted to WH in 1944. The records showed that over the 5 years until he died at WH, he was admitted & discharged about 4 times, staying with his daughter for anything from a few weeks to about 18 months. So he did have a home to go to.
I now know that this term of: "No fixed abode" was put on a person's DC when that person was a permanent resident of an institution. The informant who registered the death "The Occupier" on the DC, would be a member of staff at WH. Usually there was a person who did this job of registering deaths, it's the same at all hospitals.
The place of my grandfather's death was not given as Westminster House it actually said: Place of death: 241, Westminster Road, which I found was actually Westminster House.
They don't make it easy for us researchers do they!
Hope this Helps
