"Excellent service from Mark and Oliver. New alarms and cameras fitted swiftly and efficiently. Prompt and courteous service from start to finish. Would highly recommend."
"I contacted Third Eye having received a recommendation of their service. Oliver quickly attended to talk me through the options and provided me with a quote which we adjusted as I wanted a few extras. Within three days I had the uber-professional Alex round who fitted our new system. He took his time to talk us through how it works and the additional services TEIS provide. He was polite, courteous and respectful of our property and time. Having spoken to other companies and had a useless ADT alarm previously, I wouldn't hesitate to recommend TEIS."

Approached Third Eye to do the maintenance and monitoring of our previously installed Intruder alarm including lone worker. Oliver and the team were friendly efficient and confirmed the prices for what was involved /covered. Worked through our system and competently checked and tested to ensure the installation was compliant. Great communication both pre and post works. They are also quick with our ever changing keyholder instructions and process them quickly and efficiently.
Very impressed with the standard and care with which Third Eye went about installing our intruder alarm system. Alex was very fastidious on checking where we wanted the sensors put and explained everything very clearly and patiently afterwards. Would recommend.
Helpful, friendly, knowledgeable, and competitively priced. Third Eye were great, someone had tried to break-in and we wanted to sort an alarm quickly they came within a few days and did the survey. No hard sell. We ended up wanting a few extra shocks and PIRs than on the survey. They spent time going through the options and even offered to come back and fix one of the shocks on the bathroom window as the window was damaged and needed replacing, for no extra charge. Simple to operate great product.
Polite, clean and efficient service from the engineer.
Excellent, swift service on Bank Holiday. Very reliable company with trusted workforce.
Service carried with their usual efficiency. Came on time
Great experience dealing with Third eye from initial consultation through to final installation. Always receiving a quick reply to our questions and the engineer did a great job on the day. Polite, knowledgeable and took the time to talk us through everything. Had a question in the evening, rang the out of hours number and also received a great service. Thoroughly recommend!
We are a local community rugby Club (Barnet Elizabethans RFC). We have had issues with vandalism and break ins and needed to enhance security. Third Eye had great reviews and were recommended. I approached Third Eye with a brief of what we were trying to achieve and a budget that we had to spend. The Third Eye team arranged a visit the following day to complete a needs assessment survey and promptly followed up with the pricing that was within the budget. Third Eye took the time and really listened to what we needed and matched every part of it. We now have our system installed and workin
Amazing service, engineers super helpful and the office are very efficient. Highly recommend
I had been looking for a new alarm for a while and with some research came Oli @ Third Eye. I made contact and he talked me through all options and made me feel reassured of the options I was going for. The team came round to do the install and it was the most efficient install . Very tidy, minimal distribution and a great demo at the end to show us what to do ! 100% recommend Third Eye if your looking to keep your family home safe.
Super amazed with the work that said I carried out at my commercial unit. I cannot recommend these guys high enough!! Outstanding service unbelievable value for money and will certainly be recommending to all friends and family!!..
We have been using Third Eye on all of our works including access control and CCTV for many years now, and will continue to do so as their service is second to none! They are extremely attentive and we would never hesitate to recommend them to any of our clients.
Had my annual visit, and as always, prompt and effective. They were very COVID aware and made sure I stayed within my comfort levels while making sure that the job got done.
Very efficient as always, the alarm has rarely given us problems and has thwarted at least one attempted burgalry. Veyr happy to have it and Third Eye to maintain it.
Very reliable and friendly customer service. Always on time and complete a fantastic job quickly. Highly recommended.
Excellent service from Third Eye as expected. Open and honest from start to finish of the job, the upgraded alarm works fantastically and we feel much safer in our home as a result. The engineer arrived on time and worked effectively to get the job completed. Would definitely recommend to all!
