Fire Alarm Installation in London

A fire alarm only protects people if it is installed correctly, because poorly placed detectors or the wrong cable can stop it working. Therefore, our fire alarm installation service follows BS 5839 and BS 7671 on every job.

For example, we install interlinked smoke alarms in family homes, Grade A systems in HMOs and addressable systems in offices, shops and warehouses. In addition, every system is tested and certified before handover.

The service

What our fire alarm installation includes

We install complete systems, whether we designed them or you already have a design. Also, we keep disruption to a minimum.

Detectors and sounders

First, we fit smoke, heat and multi-sensor detectors, together with sounders and beacons.

Control panels

Next, we install conventional or addressable panels, so every zone is clearly shown.

Manual call points

Then, we also fit call points on escape routes and, for example, at final exits.

Fire-resistant cabling

In addition, we use fire-resistant cable and metal fixings, because cables must stay up in a fire.

Domestic interlinked alarms

For homes, we also fit mains-powered, interlinked alarms with battery backup.

Testing and certificates

Finally, we test every device and issue an installation certificate.

The standards

Fire alarm installation to BS 5839

For non-domestic buildings, we install to BS 5839-1:2025. In particular, cables must be fire-resistant and supported by non-combustible fixings, so they do not collapse in a fire.

For homes, we install to BS 5839-6. Therefore, a typical house gets a Grade D1 or D2 system, while larger HMOs often need a Grade A system with a panel.

Grade D1For example, mains alarms with a sealed battery
Grade APanel systems, for example in larger HMOs
AddressableAlso, systems that show the exact device in alarm
System types

Which fire alarm installation do you need?

In short, the right system depends on the building. For example:

Homes and flats

For example, interlinked smoke and heat alarms, because every alarm sounds when one detects a fire.

HMOs and blocks

Also, Grade A panel systems for larger HMOs and communal areas.

Commercial systems

In addition, conventional or addressable systems for offices, shops and warehouses.

When you need it

When do you need a new fire alarm?

In short, book a survey when:

  • For instance, your fire risk assessment recommends a new system
  • Your existing system is old or, for example, keeps false alarming
  • You are converting a property into flats or, for example, an HMO
  • You are renovating or, alternatively, extending or rewiring
  • Your insurer or local authority has asked for improvements

Also, the GOV.UK guide to workplace fire safety and the London Fire Brigade guidance explain your duties.

FAQ

Fire alarm installation FAQs

How long does a fire alarm installation take?

In short, it depends on the building. For example, a house often takes one day, while a commercial system can take longer.

Can you install a system designed by someone else?

Yes, because we install to the design and to BS 5839. However, we will point out anything that does not look right.

Do I need a mains-powered system in a rental?

In most rented homes and HMOs, yes, because the risk is higher. For example, BS 5839-6 usually calls for mains-powered, interlinked alarms.

Can you work outside business hours?

Yes, and in addition, we can work evenings or weekends to avoid disrupting your business.

Will I get a certificate?

Yes, because every fire alarm installation is tested and certified before handover.

Can you upgrade my old system?

Yes, for example, we can often reuse cable routes and replace an old panel and detectors.
