Fire and Carbon Monoxide alarm compliance: Supporting UK electricians from design to handover

Compliance

1 July 2026

Last Updated: 22 July 2026

For professional electricians, a compliant domestic fire and CO alarm installation begins long before the first device is fitted.

System design, installation, commissioning, documentation and resident guidance must work together to support safety and regulatory compliance.

FireAngel helps electrical contractors, specifiers and housing professionals manage this process through its design service, professional training and connected alarm technology.

Start with a compliant design

FireAngel is the first UK manufacturer to offer a fully insured design and specification service certified to BS 5839-6 and BAFE DS301.*

Available free of charge, the service provides the documentation needed to support a compliant installation, including:

  • System design drawings
  • Wiring schematics
  • Design certification
  • A detailed system overview

This documentation can simplify client approvals, give installation and commissioning teams clear instructions, and provide an auditable record from design through to handover.

It can be especially valuable for complex projects, including HMOs, social housing developments and larger domestic properties.

Build competence and demonstrate compliance

Standards, legislation and best practice continue to evolve. Electricians working with domestic fire and CO alarm systems must keep their knowledge current and demonstrate professional competence.

FireAngel training is designed for installers, electrical contractors and housing professionals. Courses cover BS 5839-6, domestic alarm system design, installation and commissioning best practice, carbon monoxide protection and the Building Safety Act 2022.

The training helps professionals make informed decisions, reduce the risk of non-compliant work and demonstrate accountability to clients, residents and duty holders.

Compliance beyond installation

A compliant system must remain safe and effective after handover.

FireAngel Grade D1 fire alarms include a home occupier information QR code label for the consumer unit. It gives residents access to guidance on alarm testing, maintenance and fire safety, including advice that children may not always wake to traditional alarm tones.

The label also identifies the circuit supplying the alarm system, helping prevent accidental isolation of the mains supply.

By keeping product and safety information accessible throughout the installation’s life, the label supports the recommendations of BS 5839-6 and encourages correct ongoing system management.
