If you’re searching for a trusted alarm installation company, the real question is simple: can you verify the installer’s track record and standards, not just the sales pitch?
Third Eye Installation Systems is based in Whetstone and supports homes and businesses across North London, including Barnet. You can see our reviews, our accreditations, and what customers say about the experience.
Trusted Alarm Installation Company Reviews That You Can Verify
When people say “trusted”, they usually mean two things:
- The alarm system installation is done properly (no cutting corners, no mess, no guesswork)

On the Which? Trusted Traders review summary, Third Eye Installation Systems Ltd shows:
- 4.8 average rating
- 334 reviews
- 100% of customers say they’d recommend
That matters because it’s an independent platform where customers leave feedback about punctuality, communication, workmanship, and value.

FAQs
1. Do I need a monitored alarm?
Not always. Many homes are well served by an insurer-friendly intruder alarm plus good entry-point coverage and clear external deterrence. Monitoring can make sense for higher-risk properties or certain commercial sites.
2. Can you work with an existing alarm?
Often, yes. A takeover can be a cost-effective way to improve reliability and usability without starting from scratch.
