I've used Third Eye on numerous occasions over the last 10 years or so - either to service or replace existing house alarm systems in my own home and also a rental property. Always found this company to be efficient, helpful and professional - I'd happily recommend.

ThirdEyeIS were excellent! Alex arrived on time, discussed the installation options, are carried out the installation very professionally. The cctv had to be installed in very awkward positions and this was done really well. I have no hesitation in recommending them.

Third Eye Installations was not the first company I used to update my CCTV and alarms systems, which was a big mistake as the Company that did the work were a right shamble. I found Third Eye through the Which Trusted Trader website. I explained that my CCTV system was not functioning in the way I needed it to. Oliver in the office was confident that he could help me. Vijay the Engineer turned up a couple of days later and was friendly and knowledgeable.

He thoroughly inspected both the alarm and CCTV systems. Two of the cameras had been incorrectly installed which over time would have allowed water ingress causing the cameras to fail. Desktop software was configured to provide a constant live view. My home is now secure with both CCTV and alarm systems working the way I need them to. I have peace of mind with a one year maintenance contract and knowing that I am dealing with a NACOSS registered Company.

First class. Third Eye quoted quickly and installed my replacement system exactly to time and highly efficiently. Their office always responded promptly and helpfully and the installers clearly knew exactly what they were doing and were to time, clean, tidy and courteous. Links to central monitoring station and police were quickly completed and hassle free. I have no hesitation in recommending Oliver Formby and Third Eye Installations as representing good value for money and providing a first class and efficient service.

Inal did a very professional job (as Third Eye always do) and intelligently and logically worked through and resolved a complex router issue. I would highly recommend Third Eye, we have been a customer for over 4 years and issues are always resolved promptly and professionally.

Alex attended to service the CCTV cameras, he was exceptionally professional and pleasant he attended on time, ensured all cameras focused on access points and he cleaned all cameras. I will recommend Third Eye should you be interested. Alex thank you for all your effort this afternoon.

Outstanding service from qualified men installing perfect systems for me to use easily. I would definitely recommend this shop to another person as they know what they are doing and will equip you with the appropriate tech that works best for you.

Third Eye installed the cameras and alarm system at our shop almost three years ago. The kit is great quality and the service has always been swift and professional. Oliver is always on hand with ad-hoc queries and always happy to assist. Service:Security cameras

We used third eye to fit a alarm system at our house approx 4years ago, communication from initial enquiry to quote to install was great, very happy with the install, professional fitter with a full demonstration. Had it serviced yearly and only ever needed batteries changed so I'm very impressed with the quality. I remember we had cheaper quotes but this is my family home, price played a part of course but wasn't the defining factor. I continue to use them and would fully recommend.

Third Eye were polite, patient and helpful in answering my questions about an unsatisfactory alarm installation by another company. Our new system was installed quickly and cleanly by Lewis, their very helpful young engineer who explained the function of everything very clearly, making sure we understood how it all works - and it does. I'm happy to recommend Third Eye having had bad experiences with two other companies.
