This guide looks at several carbon monoxide detectors, each offering a different approach to home safety.

Disclaimer
Before buying, check whether free support is available locally. Some fire and rescue services, gas networks and energy support schemes offer home safety visits for older or vulnerable people, and these may include advice, checks or fitting alarms. Availability varies depending on location and eligibility, so it is worth checking with your parent’s local fire service, gas network or Priority Services Register before purchasing.
1. FireAngel FA3322 Digital Carbon Monoxide Detector
The FireAngel FA3322 is a digital carbon monoxide alarm with a display, temperature and humidity monitoring, and a long-life sealed battery. It may suit an elderly parent who would benefit from a visible screen, especially if a carer wants to check readings during visits.

3. Firechief Carbon Monoxide Detector
The Firechief Carbon Monoxide Detector is a battery-powered alarm with visual and audio alerts, an LCD display and a 5-year battery included. It may be a practical choice for a parent’s home where a straightforward, portable alarm is preferred.
The visual and audible warning features may offer added reassurance, although carers should still make sure the alarm is tested regularly and placed correctly.

✔️ LCD display – Provides a visual indication as well as an audible alarm
✔️ Visual and audio alerts – Useful where extra warning signals are helpful

4. Aico Detector, White, EI3018
The Aico Detector, White, EI3018 is a mains-powered carbon monoxide alarm designed for more permanent installation. This is less of a quick standalone purchase and more of a fitted safety option. It may be useful where a parent’s home already has, or needs, a more integrated alarm system.
Pros:
✔️ Mains-powered – Designed for long-term installed protection
✔️ Back-up power – Helps maintain protection during a mains power issue

A thoughtfully chosen carbon monoxide alarm can make your parent’s home safer and give you extra reassurance. It should be tested regularly, replaced at the end of its life, and used alongside regular servicing of boilers, fires and other fuel-burning appliances.
Before purchasing, it is worth checking whether your parent may be eligible for free support through their local fire and rescue service, gas network, energy provider or Priority Services Register. In some areas, this may include a home safety visit, advice or fitted alarms.
