FAQs
Why should I choose hard-wired smoke detectors instead of battery-only units?
Hard-wired detectors are permanently connected to your property’s electrical circuit, so they are always powered and cannot accidentally be disabled by a dead or removed battery. In the event of a power outage they automatically switch to a built-in back-up battery, giving you the best of both worlds. Because each unit in our Cosby installations is also interlinked, when one detector senses smoke every alarm in the building sounds, providing earlier warning and extra evacuation time.
How many smoke detectors do I legally need in Cosby and where should they be located?
Leicestershire Fire & Rescue Service recommends (and UK Building Regulations Part B requires for most new or significantly altered homes) that a mains-powered, interlinked detector is fitted on every storey, with additional units in high-risk rooms such as living rooms, bedrooms and any space containing a solid-fuel-burning appliance. For commercial premises in Cosby, BS 5839-1 category rules apply and we can design a scheme that meets your exact risk assessment. Our surveyors will visit free of charge and map out the optimum locations to stay compliant and fully protected.
Can you install modern smoke detection in older Cosby properties without major disruption?
Yes. We use low-profile 230 V detectors with wireless or radio-frequency interlink modules, so the alarms communicate without the need for new interlink cabling. We only need a nearby lighting circuit or fused spur for each unit, keeping chasing and re-decorating to an absolute minimum. Where wiring is unavoidable, we employ surface mini-trunking that can be painted to blend in. Listed-building guidance is also followed so the character of your property is preserved.
What ongoing maintenance do hard-wired smoke detectors require?
We recommend pressing the test button on every alarm once a month and vacuuming the detector vents gently twice a year to prevent dust build-up. Backup batteries should be replaced every 3–5 years (or sooner if the low-battery beep sounds). In accordance with manufacturer guidance and BS 5839, detectors should be replaced entirely after 10 years because the sensing chamber degrades over time. Our Cosby service plans include annual inspection, cleaning, battery replacement and a written compliance certificate.
Can your smoke detectors integrate with other safety or smart-home systems?
Absolutely. The electrical detectors we supply in Cosby are available with relay bases or radio-modules that can trigger third-party systems such as security alarms, auto-diallers, smart speakers and home-automation hubs (e.g., Alexa, Google Home, SmartThings). For commercial sites we can connect the detectors to panel-based fire alarm systems that provide zone indication, remote monitoring, and automatic fire brigade signalling, helping you meet BS 5839-1 and insurance requirements.
What does a typical installation cost and what warranty do you offer?
For an average three-bedroom house in Cosby, supply and installation of three hard-wired, interlinked smoke detectors with battery back-up starts at about £275 + VAT, including certification. Larger homes or commercial premises are priced after a free site survey. All detectors come with a 5-year manufacturer’s warranty, and our workmanship is guaranteed for 12 months. Optional maintenance contracts start from £45 per year, covering annual inspection, testing and battery replacement so you remain fully compliant.
