FAQs
Quick answers to common questions about security systems.
How much do security systems cost to install?
Basic alarm systems start around £1,500 for small properties, whilst integrated systems with CCTV and access control range from £5,000 to £30,000+. Final cost depends on site size and required features.
What security system technology do you work with?
We install and maintain systems using technology from Verkada, Texecom, Avigilon, Paxton, Hikvision and most other major security brands. We can also take over existing systems regardless of who installed them.
Does Chris Lewis offer ongoing system maintenance?
Yes. We maintain security systems with proactive servicing that prevents faults. Our false alarm rate is 6x lower than industry average, meaning fewer callouts.
Is installation covered by a warranty?
Yes. We offer up to 10-year warranties on new installations. This covers equipment failures and workmanship – not damage or misuse.
Can Chris Lewis maintain and repair systems that they did not install?
Yes. We take over systems from other installers and work with all major manufacturers. We fix 90%+ of problems on the first visit.
Are your systems insurance compliant?
Yes. We install to NSI Gold standards, which meets most insurance requirements. We’ll confirm your insurer’s specific requirements before installation.
Can I combine CCTV, alarms, and access control?
Yes. Integrated systems mean one login, one app, and complete visibility. Your alarm can trigger CCTV recording, or access control can disable alarms automatically.
How long does installation take?
Basic alarm installations take 1-2 days. Integrated systems with CCTV and access control take 3-5 days depending on site complexity. We’ll give exact timings after the survey.

We’re based about 24 miles away in Oxford. Henley is part of our immediate local area, so our engineers work here daily and can respond quickly to any security system needs.
