## Smoke & fire alarms price questions

### How much does smoke & fire alarms cost in Swadlincote?

Re-energize Electrical charges £140 — the rate we quote from, confirmed on survey, not a lead-generation estimate.

### Where should smoke alarms be installed in my home?

At Re-energize Electrical, we recommend placing smoke alarms in circulation spaces on every floor, including hallways and landings. Kitchens should have dedicated heat alarms rather than optical smoke alarms to avoid false alarms from cooking.

### Do smoke alarms have to be wired together?

Yes. Current standards require interconnected alarms, meaning that if a unit on the ground floor detects smoke, all alarms throughout the property sound at the same time to alert occupants.

### How often should mains smoke alarms be replaced?

Mains smoke alarm units have a typical operating life of ten years from manufacture. The entire alarm head should be replaced once this date passes, even if the test button continues to beep.

### What happens if there is a power cut?

Each mains-powered alarm includes a rechargeable or sealed lithium battery back-up. The alarms continue to monitor your property and sound an alert even during a mains power failure.
