Smoke and Carbon Monoxide Policy

Protecting Lives Through Early Detection All Services 4U is committed to protecting residents from the dangers of fire and carbon monoxide poisoning. Smoke alarms and carbon monoxide alarms are critical life-safety devices that provide early warning and save lives. This policy sets out our procedures for the installation, testing, maintenance, and replacement of smoke and carbon monoxide alarms in compliance with current legislation. This policy applies to all smoke and carbon monoxide alarm work undertaken by All Services 4U on behalf of our clients.

Requirement Details
Smoke alarms At least one smoke alarm on each storey with habitable rooms
Carbon monoxide alarms In any room with a fixed combustion appliance (excluding gas cookers)
Working condition Alarms must be in working order at the start of each tenancy
Repair/replace Landlords must repair or replace alarms once notified of a fault

Regulatory Reform (Fire Safety) Order 2005

The RRO applies to common parts of residential buildings and requires:

  • Suitable fire detection appropriate to the risk
  • Maintenance in efficient working order
  • Testing at appropriate intervals
  • Documentation of testing and maintenance

Building Regulations Approved Document B

Specifies smoke alarm requirements for new builds and material alterations:

Building Type Requirement
New dwellings Grade D1 LD3 system minimum (interlinked mains-powered with battery backup)
Material alterations May trigger upgrade to mains-powered interlinked system
Loft conversions LD2 system required (additional coverage of escape routes)

BS 5839 Fire Detection and Fire Alarm Systems

Part Coverage

BS 5839-6 Domestic premises — Code of Practice

Other Relevant Legislation

Legislation Relevance
Housing Act 2004 HHSRS includes fire as a hazard
Gas Safety (Installation and Use) Regulations 1998 CO detection linked to gas appliances
Building Safety Act 2022 Enhanced requirements for higher-risk buildings
Homes (Fitness for Human Habitation) Act 2018 Alarms contribute to fitness for habitation

Scope

This policy covers:

  • All residential properties where we provide maintenance services
  • Social housing, private rented sector, and leasehold properties
  • Smoke alarms (ionisation, optical, heat, multi-sensor)
  • Carbon monoxide alarms
  • Combined smoke and CO alarms
  • Domestic and communal detection systems
  • Installation, testing, maintenance, and replacement

Smoke Alarm Requirements

Minimum Legal Requirement (Rented Properties)

At least one smoke alarm on each storey that contains a habitable room.

Habitable rooms include:

  • Living rooms
  • Bedrooms
  • Kitchens (where used as living space)
  • Studies
  • Dining rooms

Non-habitable rooms (don’t count):

  • Bathrooms
  • Toilets
  • Hallways (but alarms often best placed here)
  • Landings
  • Utility rooms

Best Practice Positioning (BS 5839-6)

Location Recommendation
Hallways On each level, at top and bottom of stairs
Landings Central position on escape route
Living rooms Centre of ceiling, away from corners
Bedrooms Centre of ceiling
Kitchen Heat alarm preferred, or optical alarm >3m from cooking

Where NOT to Install

Location Reason
Within 300mm of walls/corners Dead air space
Within 300mm of lights/decorations Airflow obstruction
Near air vents/fans Airflow may prevent smoke reaching alarm
Bathrooms/shower rooms Steam causes false alarms
Kitchens (ionisation alarms) Cooking fumes cause false alarms
Garages Vehicle fumes cause false alarms
Very dusty areas Dust affects sensors
Near heating appliances Heat affects sensors
On sloped ceilings (peak) Dead air at apex

Alarm Types

Type Technology Best For Avoid
Ionisation Detects small particles (fast-flaming fires) Bedrooms, living rooms Kitchens, dusty areas
Optical (Photoelectric) Detects larger particles (smouldering fires) Hallways, landings, near kitchens N/A
Heat Detects temperature rise Kitchens, garages Sole protection (slow response)
Multi-sensor Combined optical and heat Any location More expensive

Power Supply Categories (BS 5839-6)

Grade Power Supply Typical Application
Grade A Fire alarm system to BS 5839-1 HMOs, sheltered housing
Grade B Mains-powered system with standby supply Higher-risk domestic
Grade C Mains-powered with no standby Basic new build spec
Grade D1 Mains-powered with battery backup Standard new build (10+ years)
Grade D2 Mains-powered without battery backup Older new builds
Grade E Primary battery (10-year lithium) Existing properties
Grade F Replaceable battery Minimum standard (existing)

Coverage Categories (BS 5839-6)

Category Coverage Typical Application
LD1 All areas including highest risk rooms Enhanced protection
LD2 Escape routes + high-risk rooms (kitchen, living room) Loft conversions
LD3 Escape routes only (hallways, landings) Minimum standard

Interlinking

Why interlink?

  • When one alarm activates, all alarms sound
  • Ensures residents are alerted wherever they are
  • Essential for multi-storey properties
  • Required for new builds and loft conversions

Interlinking methods:

  • Hardwired (cable between alarms)
  • Radio frequency (wireless)
  • Hybrid (hardwired base units with RF link)

Resident Advice Card

Your Smoke and CO Alarms

✓ Test smoke alarms weekly — press and hold the test button ✓ Test CO alarms monthly — press and hold the test button ✓ If the alarm chirps, the battery may be low — report it ✓ If the alarm doesn’t sound when tested — report it immediately ✓ Never remove batteries or disconnect alarms ✓ Never cover or paint alarms

If Your Smoke Alarm Sounds:

  1. Alert everyone in the property
  2. Get out and stay out
  3. Call 999
  4. Do not re-enter until fire service says it’s safe

If Your CO Alarm Sounds:

  1. Stop using all fuel-burning appliances
  2. Open windows and doors to ventilate
  3. Get everyone outside into fresh air
  4. Call the Gas Emergency Line: 0800 111 999
  5. Do not re-enter until advised safe
  6. Seek medical attention if anyone feels unwell

Carbon Monoxide Safety

The Danger of CO

Carbon monoxide (CO) is:

  • Colourless, odourless, tasteless — you cannot detect it without an alarm
  • Produced by incomplete combustion of fuels (gas, oil, wood, coal)
  • Potentially fatal — causes around 30 deaths per year in the UK
  • A cause of long-term health effects even at low levels

Symptoms of CO Poisoning

Severity Symptoms
Mild Headache, dizziness, nausea, tiredness
Moderate Confusion, drowsiness, fast heart rate
Severe Loss of consciousness, seizures, death

Key indicator: Symptoms improve when away from the property.

Sources of CO

Source Risk
Gas boilers Blocked flue, poor combustion
Gas fires Faulty appliance, blocked flue
Gas water heaters Blocked flue, poor ventilation
Oil boilers Faulty appliance, blocked flue
Solid fuel fires Blocked chimney, poor ventilation
Wood burners Blocked flue, closed vents
Portable heaters Any fuel-burning portable heater
BBQs/generators Brought indoors (never do this)
Vehicle exhaust Attached garage, running engine

CO Response Procedure

If CO alarm sounds:

  1. Stop — Turn off all fuel-burning appliances if safe to do so
  2. Ventilate — Open all windows and doors
  3. Evacuate — Get everyone outside into fresh air
  4. Call — Gas Emergency Line 0800 111 999 (for gas) or 999 (if unwell)
  5. Do not re-enter — Until appliances have been checked by Gas Safe engineer
  6. Medical attention — If anyone has symptoms, attend A&E and inform them of possible CO exposure

Our Response to CO Incidents

Scenario Action
CO alarm activation reported Emergency response, Gas Safe engineer attend within 24 hours
CO alarm faulty Replace within 24 hours if combustion appliance present
