Are mains linked smoke detectors mandatory on domestic rentals

As above.  Are mains linked detectors mandatory or are battery operated acceptable. 

Thanks   Gary

  • I think it's got more confusing as technology changes - battery-only used to mean a PP3 that would go flat after a year and could be removed by tenants on a whim and mains only ones could be defeated by a power cut (or switching off an MCB). But now we have the option of mains + backup battery (or capacitor) or even battery ones that where the battery is good for the lifetime of the detector (10+ years) and sealed in so it can't be removed - so all the pros and cons can dance about a bit.
