Smoke alarms save lives - that's a fact. But with ionisation, optical, heat, and combined alarms on the market, choosing the right one can feel overwhelming. And with regulations changing, it's important to get it right. Here's a simple guide for Thanet homeowners.
The Why: What's Actually Going On
Ionisation alarms detect fast-flaming fires (e.g. paper, grease) quickly but can false-alarm from cooking. Optical (photoelectric) alarms are better at detecting smouldering fires (e.g. upholstery, wiring) and are less prone to cooking false alarms. For most homes, optical in living areas and heat detectors in kitchens are recommended. From 2026, building regulations favour interlinked alarms (usually RF or wired) so that when one goes off, they all do. Landlords must comply with the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022.
Roy's Pro Tip
Fit optical alarms in hallways and landings. Use heat detectors in kitchens - not smoke alarms - to avoid false triggers from toasters and frying. Interlink them so the whole house is alerted.
Safety Warning
Never remove or disable a smoke alarm because of false alarms. Relocate it or fit a heat detector instead. Test alarms monthly. Replace units over 10 years old.
