Electrical Smoke Alarms / Fire Alarms: Mains-wired smoke and heat alarms are connected to the home's electrical supply with a battery backup, and interlinked so that when one alarm sounds, they all sound. Cardiff Electrician installs interlinked smoke, heat and carbon monoxide alarms for homeowners and landlords across South Wales, wired and tested to BS 7671.
A battery smoke alarm on the landing will not wake someone asleep in a back bedroom with the door shut if a fire starts in the kitchen. Interlinked alarms solve that. When one detects smoke or heat, every alarm in the property sounds, giving everyone the earliest possible warning to get out.
Jorge recommends where alarms should go, with smoke alarms in hallways and landings and heat alarms in kitchens, then wires them to the mains with battery backup. Welsh rented homes need mains-wired interlinked smoke alarms on every storey, so many of our alarm installs are for landlords across Cardiff.

- You let a property in Wales and need alarms on every storey
- Alarms are past their replacement date or keep chirping
- You are rewiring, extending or converting a loft
- Your kitchen has a smoke alarm that goes off when you cook
- You run an HMO or building with shared areas
What's included
Smoke and heat alarm layout
We position smoke alarms in hallways and on landings and heat alarms in kitchens, where smoke alarms would give false alarms, following current guidance for domestic fire detection.
Mains wiring with backup
Alarms are wired to a suitable mains circuit with built-in battery backup, so they keep working during a power cut and do not rely on someone remembering to change batteries.
Interlinking
Every alarm is interlinked, by wiring or a wireless link, so that when one sounds they all sound throughout the property, giving everyone the earliest possible warning.
Testing and certificate
We test each alarm and the interlink, show you how to test and silence them and issue the relevant BS 7671 certificate for the electrical work.

Electrical Smoke Alarms / Fire Alarms FAQs
What alarms do Welsh rented homes need?
Welsh rented homes need mains-wired interlinked smoke alarms on every storey. Depending on the property, heat alarms in kitchens and carbon monoxide alarms near fuel-burning appliances may also be needed. We install alarms that meet these requirements and provide a certificate for the electrical work.
What is the difference between a smoke and heat alarm?
A smoke alarm detects smoke particles and is best for hallways, landings and living areas. A heat alarm detects a rapid rise in temperature and suits kitchens, where cooking fumes would set off a smoke alarm. Most homes need a mix of the two, interlinked together.
Do mains alarms still have batteries?
Yes. Mains-wired alarms have a built-in backup battery, often a sealed long-life type, so they keep working during a power cut. The mains supply means they do not depend on the battery day to day. Alarms have a replacement date printed on them, usually around ten years.
Can wireless interlinked alarms be used?
Yes. Many mains-wired alarms use a wireless radio link between units, which saves running interconnecting cables between floors. Each alarm still has its own mains supply. It is a good option in finished homes where you want to avoid lifting floors or chasing walls.
What affects the cost of installing smoke alarms?
The number of floors and alarms, whether the alarms are hardwired or wirelessly interlinked, access through lofts and floors and whether carbon monoxide or heat alarms are also needed. Fitting alarms during a rewire, when floors are already up, is often the most efficient time.

I had a number of small electrical jobs for Jorge to do. He completed everything quickly, professionally and to a high standard. Jorge was very polite and helpful and clearly takes pride in his work. I would 100% call him if I need more electrical work doing.
I have been a private landlord 25 years and can count the reviews I've left on one hand. I've known Jorge several years. He is a trusted professional, timely and charges competitive rates.
We initially asked Jorge to help us after being let down by another electrician, and he was only too happy to help make some bad work safe... Jorge always explains what is going on and helps us understand more about how electrics work. He is thorough, leaves no mess behind and very reliable.
