Choosing the Right Burglar Alarm System
Bells-Only
The most straightforward option - when triggered, the alarm sounds a loud external siren to deter intruders and alert neighbours. No monitoring contract required. Ideal for lower-risk properties or as a visible deterrent.
Best for:
Lower-risk residential properties
Those who don't want a monthly monitoring fee
Visible deterrence on a budget
Speech Dialler
When triggered, the alarm automatically calls a list of nominated contacts (family members, neighbours, or a keyholder) to alert them of an activation. No professional monitoring centre involved.
Best for:
Homeowners wanting self-managed alerts
Holiday homes and second properties
Properties where keyholders are nearby
Professionally Monitored
When triggered, the alarm contacts a 24/7 professional monitoring centre who will attempt to reach you, dispatch a keyholder, or alert the police if necessary. The highest level of protection available.
Best for:
Higher-risk properties
Businesses and commercial premises
Those wanting maximum peace of mind

Is Your Burglar Alarm PSTN-Ready?
BT is switching off the UK's analogue phone network in January 2027. If your existing burglar alarm uses a phone line to contact a monitoring centre, it will stop working when the switch happens, often without any visible warning on the alarm panel itself.
Three quick checks:
Your alarm was installed more than five years ago
Your monitoring contract references a phone line or BT line
You haven't been contacted by your current provider about an upgrade

Burglar Alarm FAQs
-
Yes — research consistently shows that visible alarm systems act as a strong deterrent. Most opportunistic burglars will avoid a property with a visible external bell box or CCTV in favour of an easier target. A professionally installed SSAIB-accredited system also qualifies for insurance discounts with most UK insurers.
-
In many cases, yes. Most UK home insurers recognise SSAIB-accredited alarm systems and offer a premium reduction for properties that have one installed. The exact saving varies by insurer and policy — check your policy documents or contact your insurer directly.
-
A smart alarm system connects to your home broadband or mobile network, allowing you to arm and disarm remotely via a smartphone app, receive instant push notifications when the alarm triggers, and view a live activity log. GMSE installs smart alarm systems as standard where app control is required.
-
Yes — in most cases we can upgrade or expand an existing alarm system rather than replacing it entirely. We can add additional sensors, upgrade the communicator to 4G or IP, or integrate app control into an existing panel. Book a free survey and we'll assess what's possible.
-
Yes — we offer alarm systems linked to a 24/7 professional monitoring centre. In the event of an activation, the monitoring centre will attempt to contact you and, if necessary, dispatch a keyholder or alert the police. Monitoring is available as an optional addition to any new installation.
