Trusted by Leading Residential Architects Across Oxfordshire and Beyond

I walk around my home now with a real sense of pride.
Chris Lewis understood what I wanted to achieve. The team listened very closely to what I wanted to do and then advised me on the best options. That for me was the buying decision because I had great confidence from the outset that the sales director took on board what I wanted and then fed back to me his own idea, without trying the hard sell.

Frequently Asked Questions
How much does a comprehensive security system cost?
Investment varies significantly based on property size, protection requirements, and system complexity. Costs include security assessment, equipment, installation, commissioning, and NSI certification, with optional professional monitoring. We provide transparent quotations following detailed property surveys.
Can security systems be installed in listed or heritage properties?
Yes. We’ve delivered comprehensive security in Grade I and Grade II listed properties using conservation-approved techniques—wireless systems, discreet cameras, underground gate motors. We handle planning applications and conservation officer consultation whilst meeting insurance requirements.
Will security equipment be visible and obvious?
Visibility depends on your security strategy. Discreet installation is possible — small cameras in building-matching colours, wireless sensors, concealed positioning. However, some visible deterrent value exists. We balance protection effectiveness with aesthetic sensitivity during consultations.
Do different security systems work together?
Yes — integration is fundamental. CCTV activates when alarms trigger, gates coordinate with access control, lighting responds to movement. “Leaving Home” scenes arm alarms, activate recording, and close gates—providing coordinated defence rather than isolated systems.
What ongoing maintenance do security systems require?
Annual maintenance is essential for reliability . Insurance mandates servicing, gates need safety testing, wireless connections require testing. We provide proactive contracts with guaranteed response times, remote diagnostics, and compliance documentation.
Can you takeover security systems installed by other companies?
Yes. We regularly takeover systems from previous installers—including comprehensive assessment, configuration documentation, and NSI certification restoration. We service all major platforms with no penalty for choosing us as your ongoing provider.
How does professional monitoring work?
When systems trigger, signals reach NSI Gold monitoring centres. Operators verify alerts—calling keyholders, reviewing CCTV—then escalate genuine intrusions to police. Monitoring operates 24/7, protecting property whether you’re asleep, travelling, or unable to respond.
