Fire alarm installation

Fire Alarm System Installation for London and Luton Properties

A fire alarm system must be designed around how a building is actually used. It’s not just about fitting detectors — it’s about choosing the correct alarm category, placing devices properly, and making sure the system meets current fire safety law.

We provide fire alarm installation services for commercial and domestic properties across London and Luton, delivering systems that are practical, compliant, and suitable for inspection by local authorities and insurers.

Fire Alarm Installation and Legal Requirements

Fire alarm systems in England are required under the Regulatory Reform (Fire Safety) Order 2005, which places a duty on the Responsible Person to provide appropriate fire detection and warning.
The Fire Safety Act 2021, brought fully into effect in 2022, reinforced fire safety responsibilities for multi-occupied residential buildings. Local councils in London and Luton now expect fire alarm systems to match the level of risk identified in the Fire Risk Assessment, rather than relying on generic installations.
Our installations are designed to reflect:

  • Fire Risk Assessment findings
  • LACORS housing fire safety guidance
  • Local authority enforcement expectations

Fire Alarm Categories Explained Simply

We design and install fire alarm systems in line with BS 5839 guidance, selecting the correct category for the building.

Category M

Manual systems using call points. Common in lower-risk commercial buildings.

Category L – Life Protection

Designed to protect occupants:

  • L1 – Detection throughout the building
  • L2 – Escape routes and higher-risk areas
  • L3 – Escape routes
  • L4 / L5 – Limited or specific risk coverage

Category P – Property Protection

Focused on early detection to limit fire damage:

P1 – Detection throughout

P2 – Detection in defined risk areas

Domestic Fire Alarm Grades

For homes and smaller residential buildings, systems are installed to BS 5839-6, including:

  • Grade D – Mains-powered alarms with battery backup
  • Grade A – Panel-based systems for larger or higher-risk residential premises

System grade is selected based on occupancy, layout, and fire risk.

We provide fire alarm installation across:

London

All boroughs
(EC, WC, N, NW, E, SE, SW, W, UB, TW, CR, BR, RM, IG)

Luton

Luton and surrounding areas
(LU1–LU7)

Every installation follows a clear process:

  • Review of the building and its use
  • System design to the correct BS category or grade
  • Professional installation by competent engineers
  • Testing, commissioning, and handover
  • Clear advice on testing, servicing, and certification

This ensures the system works properly and meets compliance expectations.

In the UK, fire alarm systems in residential and non-residential buildings are classified into different grades based on their design, components, and level of protection. These grades are defined in BS 5839-6, the British Standard for fire detection and fire alarm systems in domestic premises.

Choosing the right grade of fire alarm is essential for both safety and legal compliance — especially in HMOs (Houses in Multiple Occupation), rented properties, and premises with sleeping accommodation.

Grade A High Level Fire Protection

Grade A systems are designed for high-risk buildings such as:

  • HMOs with 3 or more stories
  • Sheltered housing
  • Residential care homes
  • Complex or large properties

Key Features of Grade A:

  • Control panel with backup power
  • Smoke and heat detectors wired to the panel
  • Manual call points (break glass units)
  • Alarm sounders in required areas
  • Requires professional installation and regular testing

Grade A provides a similar level of protection as commercial fire alarm systems and is designed to ensure early warning, full coverage, and central control.

Grade D – Standard Domestic Protection

Grade D systems are commonly used in standard domestic properties, such as:

  • Single-family homes
  • Small HMOs (1 or 2 stories)
  • Smaller rented flats

Key Features of Grade D:

  • Mains-powered smoke and heat alarms with built-in backup batteries
  • Alarms are interlinked (either wired or wirelessly)
  • No central control panel required
  • Simpler and more affordable than Grade A

Grade D alarms are ideal for everyday homes, offering sufficient early warning in case of fire, especially at night.
