Why You Should Use an Accredited Intruder Alarm Company

When installing or maintaining an intruder alarm system, one of the most important decisions you’ll make is who installs it.

Using an accredited intruder alarm company isn’t just about ticking a box — it directly affects:

• how reliable your system is

• whether police response is available

• insurance acceptance

• long-term performance and maintenance

• compliance with recognised standards

In short: accreditation protects you, not the installer.

An accredited intruder alarm company is independently assessed to ensure they:

• follow recognised British Standards

• install systems correctly and consistently

• use approved equipment

• keep engineers trained and vetted

• maintain proper documentation and processes

In the UK, intruder alarm installers are typically accredited by recognised bodies such as SSAIB or NSI.

These organisations regularly audit installers — meaning standards aren’t optional.

Intruder alarms rely on correct design and installation. Accreditation ensures:

• correct detector placement

• correct zone configuration

• compliant control panel setup

• correct signalling and monitoring paths

Poor installation is one of the biggest causes of false alarms and system failure.

If you require police response, your alarm system must usually:

• be installed by an accredited company

• be monitored by an approved Alarm Receiving Centre (ARC)

• comply with relevant British Standards

Without accreditation, police response may not be available.

Many insurers require intruder alarms to be:

• installed by an accredited company

• maintained under contract

• compliant with recognised standards

Using a non-accredited installer can result in:

• refused claims

• reduced payouts

• policy conditions not being met

Accredited companies work to standards such as:

• BS EN 50131 (Intruder & hold-up alarms)

• PD 6662 (UK implementation)

These standards cover:

• system grading (Grade 1–4)

• detector types

• signalling methods

• tamper protection

• maintenance requirements

An accredited installer will design your system to the correct grade for your risk level — not guess.

Accreditation doesn’t stop at installation.

Accredited intruder alarm companies must:

• carry out regular maintenance

• keep accurate service records

• ensure systems remain compliant over time

This helps prevent:

• false alarms

• signal failures

• battery issues

• non-compliance after upgrades

Not necessarily.

While very cheap installations may exist, they often:

• cut corners

• use lower-grade equipment

• lack proper signalling

• fail insurance or police requirements

An accredited installation focuses on long-term reliability, not short-term cost.

Before choosing an installer, you should:

• ask which accreditation body they belong to

• check the accreditation number

• verify it on the accreditor’s website

• confirm the accreditation covers intruder alarms, not just CCTV

A genuine accredited company will never hesitate to provide proof.

An intruder alarm is only as good as the company that designs, installs, and maintains it.

Choosing an accredited intruder alarm company means:

• higher reliability

• recognised compliance

• access to monitoring and police response

• peace of mind that standards are being met

It’s one of the simplest ways to avoid problems later.
