An HMO conversion typically requires LD2 grade D mains-wired interlinked smoke detection, FD30s fire doors with intumescent strips and smoke seals on every habitable room, fire compartmentation between floors, and emergency lighting on escape routes. None of that is extravagant; all of it costs.

Our HMO take-offs include a clear fire safety section so the cost is visible from the start rather than emerging mid-build.

For Plymouth properties the local fire authority will typically be involved at sign-off, so the spec needs to be defensible from the design stage.
