I have recently read that although sprinklers are not mandatory for res care homes in England and Wales, certain design freedoms in res care have, since 2007, been accepted under the guidance that supports the relevant building regulations: an example is that bedroom doors need not be automatically self closing.
However in Scotland since the tragedy at Rosepark, the Scottish Building Regulations stipulated for the first time,
that all new build res care homes need to be protected by an automatic fire suppression system, and all bedroom doors in such places also need to be automatically self closing in action.
The last I ever heard about the Rosepark enquiry was that the PF had appealed the decision re the charges being dropped against the owners, and it was likely that an appeal would be held at some stage in the future, and that possibly, in the long term, once criminal proceedings are completed, there might well be an inquiry.
