What is smoke alarm installation?

Smoke alarm installation involves fitting battery-operated or hard-wired detectors throughout your home to provide early warning of fire.

An installer will determine the ideal locations within your property, fit the units, test connectivity, and advise on maintenance schedules.

• For landlords, having working smoke detectors on each storey is a legal requirement under UK fire safety regulations
• For homeowners, fitting smoke alarms is one of the simplest and most effective ways to protect your family and property

Types of smoke alarms

Different smoke detectors suit different homes:

• Ionisation alarms – Detect fast-flaming fires (e.g., paper or wood)
• Optical alarms – Better for slow-smouldering fires (e.g., upholstery)
• Heat alarms – Ideal for kitchens and garages where smoke isn’t always a fire risk
• Interlinked systems – Connect multiple alarms for maximum coverage and response

A checked smoke alarm installer can guide you on the best combination for your property layout and fire risk profile.

How much does smoke alarm installation cost?

The cost of installing a smoke alarm depends on the number of alarms, the type of system, and the complexity of wiring.

Typical UK costs average around:

• Battery-powered smoke alarms: £50 each
• Mains-wired smoke alarm systems: £200 per alarm
• App-enabled fire alarm system: £250 each
• Grade A fire alarm system: £2,500

Where to install smoke alarms

Smoke rises, so alarms are best mounted on ceilings, ideally in the centre of each room and at least 30cm from walls or light fittings.

UK Fire & Rescue Services recommend at least one alarm per floor, but larger properties often need several — especially near bedrooms, hallways, and kitchens.

Smoke alarm maintenance and replacement

Smoke alarms need minimal maintenance but must be tested regularly.

• Test every month by pressing the test button
• Replace batteries yearly, or sooner if the unit chirps
• Clean every six months using a vacuum brush to remove dust
• Replace the alarm every 10 years, as sensors degrade over time

If your alarm frequently beeps or chirps, it may need new batteries, cleaning, or replacement due to age or electrical issues.
