If you own a HMO in Cardiff and need emergency callouts, the right spec is usually not the most expensive one. On this stock the sensible answer is RCBO-per-circuit CU so one tenant fault doesn't kill the house — matched to the wiring generation, not a lift-and-shift from a new-build brochure.
That is the standard we quote to. Fixed price, honest survey, BS 5839-6 Grade D interlinked alarms, and paperwork the licensing officer won't question.
