FAQs
Why should I hire a qualified electrician to install my smoke detectors rather than doing it myself?
A competent electrician ensures that each alarm is wired to the correct circuit, fitted in the optimal position and tested to British Standards (BS 5839-6 for domestic premises and BS 7671 for electrical safety). Professional installation eliminates common DIY mistakes such as overloading lighting circuits, using the wrong type of detector in kitchens or bathrooms, and failing to interlink the alarms. You also receive an Electrical Installation Certificate or Minor Works Certificate for your records, which can be essential for insurance and when selling or renting your property.
What types of smoke detectors do you recommend for homes in Guild and why?
Current best practice is to use mains-powered optical (photoelectric) smoke alarms in circulation areas such as hallways and landings, heat alarms in kitchens and garages, and, where appropriate, multisensor alarms that combine optical and heat technology for living rooms or areas with mixed fire risks. All should include a tamper-proof lithium back-up battery so the alarm remains active during a power cut. Choosing detectors certified to BS EN 14604 (smoke) or BS 5446-2 (heat) ensures compliance with UK standards and provides predictable response times.
How many smoke detectors do I need, and where should they be located?
In a typical two-storey house, Part B of the Building Regulations and BS 5839-6 call for at least one smoke alarm on each storey and one heat alarm in the kitchen. Each smoke alarm must be within 7.5 m of any habitable room door, and at least one smoke alarm should be located on the escape route (e.g., hall or landing) on every floor. Additional alarms should be added to high-risk rooms such as living rooms with fireplaces, workshops, or utility rooms containing tumble dryers. For larger or HMO properties, a more comprehensive Grade A or Grade D1 system with interlinked detectors in every bedroom is normally required.
Do UK regulations require my smoke alarms to be interlinked, and how is that achieved?
Yes. All new-build homes and most major refurbishments must have interlinked alarms so that, when one detector activates, every alarm sounds simultaneously. Scotland’s 2022 legislation extends this requirement to all dwellings, and many insurers across England and Wales now expect the same. Interlinking can be done by a dedicated three-core cable during first-fix wiring, or retrospectively via radio-frequency (RF) bases that communicate wirelessly. Our electricians can advise on the best method for your property and ensure you remain fully compliant.
How often should smoke detectors be tested, cleaned, and replaced?
• Test every week by pressing the test button until the alarm sounds. • Vacuum or wipe the vents every three months to remove dust and cobwebs that can impair sensitivity. • For alarms with removable batteries, replace the battery annually (we recommend sealed lithium units to avoid this task). • Replace the entire alarm after 10 years (or by the manufacturer’s expiry date printed on the unit). Sensors deteriorate over time, so even apparently ‘working’ alarms can respond too slowly if they are older than a decade.
Can you upgrade my existing battery-only alarms to hard-wired or interlinked alarms without major disruption?
Yes. In many Guild properties we take power from a nearby lighting circuit, install new mains-powered alarms with a sealed back-up battery, and run surface mini-trunking or use a radio-frequency link to avoid chasing walls. This approach is quick, tidy and usually completed in a single visit. Our engineers patch-test circuits, install the alarms, verify interlinking, and issue the required electrical certificate. If you prefer a fully concealed installation, we can accommodate that during planned refurbishment works or redecoration.
