Can’t thank James enough for his expertise and help with our CCTV system. We had an issue with our system after our Wi-Fi went down, and James came out the very same day I contacted him to get everything resolved. He was also at the end of the phone to answer any questions I had after he’d left, which was incredibly reassuring. James is incredibly friendly, professional and knowledgeable, and nothing was too much trouble. I would highly recommend both James and the company to anyone needing help with their CCTV system. Excellent service from start to finish and will definitely be using them again if I was to ever have anymore issues. Thankyou again.

Exceptional Service I highly recommend Sanders Secure. James fitted our new alarm system and it was an exceptional and professional service from start to finish. Even when James came upon a problem our end, he stayed until the job was done and nothing was too much trouble for him. I particularly love the simplicity of the system and the App means I can turn the alarm on and off via my mobile - great for those who forget to set their alarm before leaving the house! Thank you so much! ⭐⭐⭐⭐⭐

My alarm system was in desperate need of a service as it hadn’t been done in several years. The people who used to service it had retired but kindly recommended James from Sanders Secure. I am so glad they did! He was so lovely, from first contact on the phone to the service itself. He didn’t try to upsell me anything, even given the age of my system. I wouldn’t hesitate to recommend Sanders Secure.

From start to finish, James was professional, knowledgeable and incredibly helpful. He fitted our new alarm system, CCTV, fire panel and smoke detectors to an excellent standard, and we couldn't be happier with the work. Everything was explained clearly, the installation was neat and professional, and James took the time to make sure everything was working perfectly before he left (Even sacrificing his own hand, by testing out the shock proof door system, giving staff members a laugh)We now have complete peace of mind knowing our security and fire protection systems are in safe hands and all up to standard. We would highly recommend James/Sanders Secure to anyone looking for friendly, reliable, professional and trustworthy company.

We had our annual intruder alarm service completed yesterday by James, and the whole experience was excellent. From the initial phone call to the service appointment, he was knowledgeable, efficient, and communicated clearly throughout. A very professional service—thank you, James.

I'm so grateful to James at Sanders Secure for paying me a visit so promptly to deal with my house alarm and to give me a detailed invoice!  It's good to know you are also based in such close proximity to my own property.  How could I have missed you in the past? I appreciated the care you also took  of my property - many callers don't even consider taking off  their shoes.  Many Thanks, Sincerely, Jean Summers

We were having problems with our security alarm which was installed 20 years ago, was unfortunately made worse by the internal cable being accidentally cut in the loft.  After reading really good reviews on the website we contacted Sanders Secure and booked a service call for an engineer to come to the house and repair the alarm. James Sanders off Sanders Secure was really friendly and very helpful, recognising the issues and repairing our security alarm system to working order. Having been informed previously by a BT telephone engineer and confirmed by James, that the line connection for our security alarm would soon become obsolete as everything was going digital we decided to purchase a new digital security system from Sanders Secure and book another date for the installation. On Friday 19 June 2026 James the engineer returned to remove the old security alarm system and install the new digital security alarm system.  Keypad, External Bell and Power Unit. Absolutely thrilled with the new Sanders Secure security system, easy to activate the system, many features, functions that enables us to activate the security system externally / holiday as well as internally and with extra security functions available should we want to add other areas to our system in the future. On completion of the installation James guided my wife and I through the download of the app, providing the required details for access to the system, patiently talking us through operating the digital alarm system and answering any questions we may have. Excellent service from Sanders Secure throughout and especially from James. Would highly recommend Sanders Secure to anyone needing a security alarm or wanting to upgrade their security system. Many thanks to James and Sanders Secure.
