Intruder Alarm Installation - Protect Your Business
Our intruder alarms operate reliably in the background, protecting your site when you’re not there. Monitoring continuously, they alert the right people when required, without false activations. That’s why we average just one false alarm every six years, compared with an industry average of one per year.

Our Intruder Alarm Benefits
Smart protection that delivers real security without the hassle. We assess your site, understand your operations, and install exactly what you need.
Minimal False Alarms
False alarms waste time, money, and credibility. Our systems average one false alarm every six years because we install them properly. We use quality equipment, position sensors carefully and adjust sensitivity correctly.
Automatic Police Callout
Burglars can be in and out in under 10 minutes. Every second after your alarm triggers could mean thousands of pounds lost. For high-risk sites, we arrange direct police response – no delays, just fast action when needed.
Rapid Remote Troubleshooting
Many problems can be fixed without a visit. Our remote diagnostics let us check your system from our control room and often sort things without sending an engineer. That means less disruption and expense for you.
Cost-Effective Alarm Monitoring
24/7 monitoring doesn’t have to break the bank. Our packages give you professional monitoring at sensible prices. No hidden fees, no surprise charges – just straightforward protection that fits your budget.

Maintenance
I have never had any problem dealing with Chris Lewis since my alarm was installed in 2015. The recent maintenance visit was helpful as engineer Donald Aiken explained what he was doing and gave useful reminders on use of the kit.
Robert Dyson
The engineer, Jamie, fitted new equipment for us and carried out our regular service/maintenance visit as well. He was very systematic and accurate in everything he did, and was charmingly courteous to us.
Sarah Porter
Excellent service from start to finish. Reliable and honest from the outset with exactly the results I’d hoped for. I would highly recommend them.

FAQs
Quick answers to common questions about commercial intruder alarm systems and installation.
What types of intruder alarm systems do you install?
We install everything from simple bells-only to sophisticated multi-zone setups with remote monitoring. Wired or wireless, conventional or smart – we recommend what fits your needs and budget.
How long has Chris Lewis been installing burglar alarm systems?
What makes your burglar alarm systems advanced?
Modern features that add value without complexity. Remote app control, smart home integration, video verification, and intelligent analytics that reduce false alarms. But “advanced” doesn’t mean complicated – everything stays simple to use.
Are your alarm installation services accredited?
Yes. We hold NSI Gold accreditation – the highest standard in the industry. This means police response eligibility, insurance approval, and guaranteed quality. Every install meets British Standards and insurance requirements.
Which manufacturers do you partner with for alarm systems?
We work with proven brands like Texecom and Verkada. We choose manufacturers based on reliability, not margins. These systems last longer, need fewer repairs, and have better support when you need parts.
Why should I install an intruder alarm system in my business?
Three reasons: protection, deterrence, and compliance. Alarms protect your assets, deter criminals and meet insurance requirements. Most commercial policies demand professionally installed, maintained alarms. Without them, claims can be rejected.
Can you design an intruder alarm system to fit my business needs?
Absolutely. Every system is designed specifically for your premises. We assess your layout, understand your operations, and create protection that works around your business. No generic packages – just tailored security.
How can I monitor my commercial intruder alarm system?
Multiple options: app control on your phone, keyfob operation on-site, or full professional monitoring from our control room. Choose what works for your business. Most clients combine app access with professional monitoring for complete coverage.
Do your commercial alarm systems meet regulatory standards?
Yes. All our installations meet BS EN 50131 and PD 6662 standards. We’re NSI Gold accredited and follow all industry guidelines. Every system we install is designed to give you the best chance of passing a insurance or compliance inspection.
Do you provide maintenance for commercial intruder alarm systems?
Yes. Regular maintenance keeps systems reliable and compliant. We offer various service packages from annual inspections to comprehensive cover with guaranteed response times. All maintenance is logged in an online portal for compliance proof.
Can I upgrade my existing intruder alarm system?
Usually, yes. We assess your current system and identify upgrade options. Sometimes adding smart features or better sensors is enough. Sometimes a new panel modernises everything. We’ll explain what’s possible and what makes sense for you.
