Under BS 5839 Part 6, smoke detectors should be installed in every circulation area — hallways and landings — on each storey of a dwelling, and in living rooms and bedrooms for higher-grade installations. Heat detectors (rather than smoke detectors) should be installed in kitchens to avoid cooking-related nuisance activations. For HMOs in Tower Hamlets, Newham, and Hackney, detectors are typically required in every habitable room. We advise on the correct positions for your specific property layout during the assessment.

Smoke detectors detect airborne smoke particles and are the primary detection device in most living areas, hallways, and bedrooms. Heat detectors respond to a rise in ambient temperature (either to a fixed point, such as 58°C, or a rapid rate of rise) — they are slower to activate than smoke detectors but are appropriate for kitchens, garages, and boiler rooms where smoke from normal use would cause nuisance alarms.

For new build homes in England, Building Regulations Part B requires interlinked smoke alarms. For existing rental properties in East London, BS 5839 Part 6 recommends interlinked alarms and the Smoke and Carbon Monoxide Alarm Regulations 2022 require working smoke alarms on every floor. HMO licensing conditions in Tower Hamlets, Newham, and Hackney typically require interlinked systems. Interlinked alarms significantly exceed the minimum standard and are our strong recommendation for all East London properties.

Battery-only alarms meet the minimum legal requirement for rental properties — provided they are working and tested. However, they do not interlink, do not provide central alarm notification, and rely on battery condition. We recommend upgrading to mains-wired interlinked alarms for significantly better protection. The cost of upgrading a 3-bedroom East London property is typically less than £400.

Mains-wired interlinked smoke alarm installation for a 3-bedroom East London property (covering hallway, landing, and kitchen heat detector) typically costs £280–£500 depending on cable run distances and the number of devices. We provide fixed written quotes after the assessment. Same-day installation available across all East London postcodes.

Mains-wired alarms should be tested monthly using the test button, and the external surface cleaned gently to prevent dust accumulation affecting sensor sensitivity. Detectors should be replaced after 10 years from the date of manufacture (printed on the unit). We advise on replacement schedules and carry out annual inspection and testing for East London landlord clients.

Yes — all East London councils including Tower Hamlets, Newham, Hackney, Waltham Forest, Redbridge, and Barking & Dagenham require working smoke alarms as a condition of HMO licensing. The specific grade and coverage required varies by council and HMO size. We carry out HMO-specific smoke alarm assessments and installations that meet the licensing conditions of all East London councils.
