In reply to 'wee brian ' you will see I said individual flat 's' , as in 'the overall building' is a house in multiple occupation if you wish to discuss this with agencies that enforce the housing act you may find it applies to the overall 'building' .
I think if you do some research into this area, you will find there have been deaths in the last 4 weeks.
As to the 'level of risk', the move to provide 'sheltered housing ' on the cheap, as lead to the removal of wardens and 'when they can afford it' to replace them with technology eg. detection linked to a remote call centre. The centres may be many miles away ( does it remind you of any other 'call centre' cost reductions), the systems installed may not be comprehensive or maintained and tested.
The reduction in the profits of private residential care homes leading to their closure and change of use to apartments, and the reduction in the number local authority residential care homes as led to occupants of sheltered housing being too vulnerable for that type of residence, couple this with the reduction in 'pastoral care' ie wardens etc, I think this is an area that will see a rise in the number of casualties ove the next few years. So in my opinion this is not a low risk area, possibly a low profit area those in the industry ?
