When was the last time you checked your smoke alarms — not just the battery, but the expiry date?
A lot of people don’t realise that smoke detectors have a lifespan, usually around 10 years. After that, the sensor inside becomes less reliable, even if the test button still works. That means you could be living with a false sense of security without knowing it.
As a domestic electrician working in homes across Hove, Brighton, Shoreham and beyond, I’ve seen plenty of outdated alarms during jobs — many well past their replacement date. It’s an easy thing to forget, but it’s also one of the most important bits of kit in your home.
🔎 How to check if your smoke alarm is out of date:
- Look for a sticker on the side or back — it should say either a manufacturing or expiry date.
- If it’s older than 10 years, it’s time to replace it.
- Not sure? Take a quick photo and I can advise.
✅ What I recommend:
- Test your smoke and heat alarms once a month using the test button.
- Replace all alarms every 10 years – or sooner if there’s any damage or beeping issues.
- Make sure they’re installed in the right locations — and interconnected if required.
I supply and fit reliable, British Standard-approved alarms for homeowners and landlords — often as part of rewires, inspections, or safety upgrades. It’s a small job that makes a big difference to your peace of mind.
