Existing Alarm?

Alarm system
takeovers

Already have an alarm - inherited, installed by someone else, or simply unmaintained? We'll take it on, service it, and look after it going forward.

Why people switch to us

Inherited an alarm?
We'll inherit it too.

When you move into a property, buy a business, or your existing alarm company folds - you're left with a system that no one is actively looking after. That's where we come in.

We take over alarm systems of any age, any brand and any grade. We'll service it, re-code it, update the documentation and, where appropriate, connect it to 24/7 ARC monitoring. No need to rip everything out and start again.

Any brand accepted
Texecom, Pyronix, Honeywell, Bosch, Risco, Scantronic, Yale, Aritech, Ajax - if it's an alarm system, we can take it on.
Full service & certification
Every sensor tested. Every siren checked. Batteries replaced where needed. You receive a compliance certificate that keeps your insurer happy.
Re-coding & access control
We change all access codes, update user PINs and re-programme the system under our NSI number so your alarm's documentation is clean and current.
Monitoring connection
If the system supports it, we can add 24/7 ARC monitoring. You get a police URN, professional operators and insurance-recognised cover.
What we take over

Systems, brands and
situations we handle

We've taken over alarms in every situation - from neglected domestic systems to commercial panels that haven't been serviced in years.

01
Domestic Alarms
Moving into a house with an existing alarm? We'll take it over, re-code it and bring it back up to standard. No need to pay for a completely new installation.
Grade 2 Domestic Any brand
02
Commercial Systems
Taken over a business with an existing alarm contract? We'll inherit the system, update the documentation under our NSI number and provide a new service schedule.
Grade 2 & 3 Commercial NSI registered
03
Outdated Panels
Older panels can often be re-certified and brought up to current standards without full replacement. We'll advise honestly - replace only what actually needs replacing.
Panel upgrades Cost-effective Honest advice
04
Adding Monitoring
Have an existing bell-only system you'd like to connect to 24/7 ARC monitoring? We'll assess compatibility and add a communicator where possible.
ARC connection Police URN Insurance approved
Brands we work with

Familiar with every
major manufacturer

We carry equipment and have trained engineers for all major alarm brands. If we're not familiar with your specific panel, we'll be honest and say so - but in 20+ years, that rarely happens.

Texecom & Pyronix
Two of the UK's most popular commercial alarm brands. We're fully trained on the full range including Veritas, Premier and Enforcer panels across all firmware versions.
Ajax & Smart Systems
Modern wireless systems including Ajax, the market-leading wireless platform. Full re-programming and cloud account transfer available.
Honeywell, Bosch & Others
We regularly take over systems by Honeywell, Bosch, Risco, Scantronic, Aritech, Yale and others. Old or new, domestic or commercial.
The takeover process

Simple, clean
transition

A system takeover usually takes a single visit. Here's what to expect.

1
Initial assessment
We visit the property, identify the system, check its current condition and advise on what's needed - service, upgrade or replacement.
2
Service visit
Full system test. Every sensor, detector and siren checked. Panel logs reviewed. Batteries replaced. Any faults identified and quoted for.
3
Re-coding
All access codes changed. User PINs updated. System re-registered under our NSI number with current documentation.
4
Monitoring (optional)
If required, we fit a communicator and connect the system to our NSI-approved ARC. Police URN applied for. Keyholders set up.
5
Annual contract
We set up an annual service schedule. You get a direct line to the same engineer - not a call centre - for any queries.

We\'ve earned these - not with incentives, but by actually looking after people.

Used Barking Dog when we moved into our house over a decade ago. They\'ve been great - annual service, and if we have any issues they\'re straight onto it.

These guys came all the way to West Sussex to install my system. They visit every year and log on remotely every six months. Thoroughly professional, personal service.
