Looking for Smoke Alarm Installation in Exeter?
Working smoke alarms save lives. The statistics from fire services across England consistently show that the risk of dying in a house fire is significantly higher in properties without working detection. Yet a substantial number of homes — including many in Exeter's large stock of older properties — have either no alarms, outdated battery units with flat batteries, or alarms positioned in ways that provide inadequate coverage.
A properly designed and installed mains-wired, interconnected smoke alarm system is a meaningful upgrade from a standard battery alarm. Mains-wired alarms cannot go flat during normal operation — they are always powered, with a battery backup that activates only during a power cut. Interconnection ensures that every alarm in the property sounds the moment any single unit detects smoke, giving occupants on every floor the maximum possible escape time.
We install smoke, heat, and CO alarm systems to BS 5839-6 — the British Standard code of practice for domestic fire detection — across Exeter and Devon. Systems are designed for the specific property layout, with the right type of detector in each location and all units correctly interconnected. All installation work is carried out by NICEIC-registered electricians and includes a full test of every unit on completion.
For landlords, we provide written installation documentation confirming the alarm types installed, their positions, and the test carried out — the evidence you need for your tenancy file to demonstrate compliance with the Smoke and Carbon Monoxide Alarm Regulations 2022.
Alarm Installation Services We Cover
Every type of domestic fire and CO detection installation across Exeter and Devon — from a single alarm to a full interconnected HMO system.
Mains-wired smoke alarm installation
Single or multiple mains-wired optical or ionisation smoke alarms, connected via spur from lighting circuit. Battery backup included. Available with or without interconnection to additional alarms.
Mains-wired heat alarm installation
Rate-of-rise heat detectors for kitchens and other cooking areas where smoke alarms would cause repeated false alarms. Interconnectable with the rest of the alarm system.
CO alarm installation
Carbon monoxide alarms for any room with a fixed combustion appliance — gas boiler, gas fire, solid fuel stove, open fire. Mains or battery units depending on location and access.
Interconnected alarm systems
Complete interconnected systems with all alarms linked — wired interconnection via cable run between units, or radio-frequency wireless interconnection for properties where cabling is difficult.
LD1 and LD2 system installations
LD1 provides detectors throughout all rooms and circulation areas. LD2 covers circulation areas plus high-risk rooms. We advise on the right category for your property and install accordingly.
HMO alarm systems
Houses in Multiple Occupation have enhanced fire detection requirements under HMO licensing conditions. We assess HMO requirements and install or upgrade systems to meet licensing standards.
BS 5839-6 compliant installations
Every system is designed and installed to BS 5839-6. Alarm types, positions, and interconnection follow the code's recommendations for domestic premises.
Battery backup systems
All mains-wired alarms include integral battery backup, ensuring continued protection during a power cut. We also supply and install standalone battery units where mains access is not practical.
Who We Help
Homeowners
Many homes have battery alarms installed during a previous refurbishment or by a previous owner that have never been serviced or replaced. Alarms older than ten years should be replaced regardless of whether they pass a test — the sensor technology inside degrades over time. We survey existing detection, advise on what is needed, and install a modern mains-wired interconnected system designed for your property layout.
Landlords
Compliance with the Smoke and Carbon Monoxide Alarm Regulations is a legal obligation for private landlords in England — and the consequences of non-compliance extend beyond a fine to civil liability if a tenant is harmed by fire. We work with Exeter landlords and letting agents to install compliant systems before tenancy start dates, provide written installation confirmation for the tenancy file, and advise on HMO-specific requirements.
Businesses and HMOs
HMO landlords face more stringent fire detection requirements under their HMO licence conditions, typically specifying a Grade D LD1 or better system with detectors in every room used as accommodation. We assess HMO properties against licensing conditions, advise on the required system, and install to meet the specific conditions of your licence. Written confirmation of the system installed is provided for your licence records.

Why NICEIC Registration Matters for Alarm Installation
Mains-wired smoke alarm installation involves connecting to the fixed electrical installation of the property — work regulated under Part P of the Building Regulations and requiring a competent electrician. NICEIC-registered engineers have been independently assessed for the technical knowledge and practical competence to carry out this connection work safely, including the correct cable type, fusing, and terminal integrity required for a reliable installation.
For landlords, the quality of installation matters beyond simple compliance. An alarm system installed by an unqualified person may not interconnect reliably, may be connected to the wrong circuit, or may be positioned in ways that provide false coverage. A NICEIC-registered electrician installs to current best practice and provides written documentation that stands up to scrutiny if the system is ever questioned.
Every engineer we book for alarm installation is NICEIC-registered. We verify registration before confirming any booking. You can verify any electrician yourself against the NICEIC register at niceic.com.
