What moves the price
- Type of alarm — a mains-powered alarm costs more to fit than a battery one, because it needs wiring to a nearby circuit.
- Number of alarms — each extra alarm adds to the parts, though fitting several in one visit takes little extra time.
- Location of the property — a rural home far from the electrician adds travel to what is otherwise a small carbon monoxide alarm job.
- Interlinked alarms — linking carbon monoxide alarms so they all sound together costs more than fitting standalone units.
Services for the maintenance and repair of the dwelling prices in Ireland are up 23% over five years (CSO Consumer Price Index, Services for the maintenance and repair of the dwelling, to 2025 December).

How to pay less
- Battery-powered carbon monoxide alarms cost less to fit than mains-wired ones, and can be put up without any wiring.
- Having every carbon monoxide alarm in the home fitted in one visit costs less than separate call-outs for each room.
- You can ask whoever services your boiler or stove to fit the alarm during that visit, saving a separate call-out.
- Testing the alarm yourself with its test button, and changing batteries yourself, avoids paying for a maintenance visit.
- Choosing an alarm with a sealed long-life battery saves buying replacement batteries and booking battery replacement visits.
Before you book

- Information about any existing gas appliances or heating systems.
- A clear understanding of your home's layout to assist in placement.
- Any previous alarm records or service history, if available.
