Why Fire Alarms and Smoke Alarms Are Not the Same as an EICR

What an EICR Covers

An EICR — Electrical Installation Condition Report — tests and inspects the fixed electrical installation in a property. This includes the consumer unit, the wiring circuits, the earthing and bonding, socket outlets, light fittings, and any hardwired equipment connected to the installation.

The EICR is conducted under BS7671 — the IET Wiring Regulations — and records the condition of the installation against the current requirements of that standard. Its primary concern is the safety of the electrical installation: whether it is at risk of causing electric shock, fire from electrical faults, or harm from inadequate protective device response.

What the EICR Does Not Cover

Fire detection and alarm systems — whether a simple set of interlinked smoke detectors or a full panel-based fire alarm system — are separate from the fixed electrical installation. An EICR inspector will note whether mains-powered smoke detectors are present and whether they appear to be connected, but they will not test the system, verify its coverage, or certify that it meets fire safety requirements.

The fire detection and alarm system in a property is governed by BS5839 — a separate standard with different inspection and servicing requirements. An EICR inspector is not typically qualified to certify a fire alarm system against BS5839, and the EICR does not attempt to do so.

BS5839: The Standard for Fire Detection and Alarms

BS5839 is the British standard for fire detection and alarm systems. Part 1 covers commercial and industrial systems; Part 6 covers domestic and residential systems.

For domestic properties, BS5839-6 defines the grades and categories of system required for different property types. The grade describes the type of components used (from Grade A, a full panel-based system, down to Grade F, battery-only individual detectors). The category describes the coverage of the system.

For most private rented houses, a Grade D system — mains-powered, interlinked detectors with battery backup — is the standard that meets the requirements. For HMOs and larger residential properties, more comprehensive systems may be required.

The Smoke and Carbon Monoxide Alarm Regulations

These requirements are separate from the EICR obligation. A landlord can have a fully Satisfactory EICR and still be non-compliant with the smoke alarm regulations — and vice versa.

• At least one smoke alarm on every storey of the property that is used as living accommodation
• A carbon monoxide alarm in any room with a fixed combustion appliance (excluding gas cookers)
• A heat alarm in kitchens where cooking takes place (as smoke alarms in kitchens are prone to false alarms)
• All alarms must be in working order at the start of each new tenancy

HMOs: Where the Requirements Are More Detailed

For HMOs, the requirements around fire detection are typically set out in the HMO licence conditions issued by the local council. These conditions will specify the grade and category of system required, the coverage, and in some cases the servicing and inspection frequency.

HMO councils take fire detection requirements seriously. A property that has a valid EICR but does not have adequate fire detection — or does not have a serviced system with documentation — can fail an HMO licence inspection on that basis alone.

What Landlords Should Ensure

The practical takeaway is that electrical safety compliance and fire safety compliance are both required, and both have their own documentation. For a privately rented house, you need a valid EICR and evidence that smoke alarms and carbon monoxide alarms are correctly installed and working. For an HMO, you additionally need documentation of the fire alarm system type, its installation, and its servicing history.

If you are unclear about which fire detection requirements apply to your specific property, your local housing authority or a fire safety consultant can advise. For the electrical side, your EICR inspector can clarify what falls within and outside the scope of the inspection.
