Why do Brynmill houses usually need Grade A systems?
Brynmill sits between Singleton Park campus and the seafront and is overwhelmingly three-storey terraced student housing, often with a converted attic bedroom and a basement kitchen. Three storeys with five or more occupants in two or more households puts the property firmly in Grade A LD2 territory under BS 5839-6: a control panel, mains-wired detection in every escape route and sleeping room, and heat detection where cooking happens. A Grade D interlinked system is rarely enough for that layout.
