We have barrel bolts on every door in the house (including the cupboards under the stairs), they are an absolute neccessity for us.
Recently I had social services coming to the house as I had requested an assessment for some respite. I was a bit nervous about the bolts, as I had heard people in the past, talk about them being a social services 'red flag'.
However, they showed no concern about them, infact they recommended 'star locks' and asked if I would like to talk with a colleague of theirs that dealt with safety and adaptations.
As others, all windows need to be locked at all times with keys removed and all external doors have alarms on them that sound when opened, it is lucky that we can lock the windows slightly open (a cm or so).
