Initial contact was simple and responsive, the sales person arrived at the agreed time and made some helpful suggestions but no hard sell. The installer did a great job and it took just one day.

We were really impressed with Spy Alarms. The service was efficient, the team especially Gary were friendly and knowledgeable, and everything was handled with professionalism from start to finish. The inspection was smooth, the system works perfectly, and the staff made the whole process easy and stress‑free. A reliable company that clearly takes pride in its work — highly recommended.

Very poor service

I recently became a customer of Spy when my existing security company sold their business to them. At my recent request Spy sent an 'engineer' to service my alarm system; he spent 2.5 hours performing the service, which usually took 30 minutes with my old supplier, almost all of the time on his mobile to the office asking how to do it, and I still have problems with the system connecting via the internet. My opinion of Spy from this first encounter is rock bottom, and unless I can get them to respond to my 3 emails I intend to seek an alternative alarm security company!

Update 19/10/2026 - Dear Roger, thank you for taking the time to speak with me and for giving me the opportunity to put things right for you. It was a pleasure assisting you, and I am pleased I have been able to arrange for your annual service to be revisited this week. As discussed, I have sent you an email with the proposed appointment date and look forward to your confirmation. In the meantime, please remember you have my direct contact details should you have any questions or concerns. I will be more than happy to assist you.

Dear Roger, Thank you for taking the time to share your feedback, although it was disappointing to read. I am very sorry to learn that your experience with us has not met the standards you expected, particularly regarding communication and the recent service visit. I completely understand how frustrating this must have been, especially as a new customer. Having reviewed your account, I can see that my colleague has explained why an alternative engineer attended instead of your usual engineer on this occasion. However, I am particularly concerned by your comments regarding unanswered emails, as this is not the level of service we strive to provide. I would welcome the opportunity to investigate this further and understand what has happened. I would also like to arrange for your usual engineer to revisit your property to investigate the ongoing issue with your alarms internet connection and ensure everything is functioning as it should. I would like to reassure you that our engineers are never working in isolation. They have direct access to our office based technical support team, who are former engineers themselves. If an engineer requires additional assistance or advice relating to a system while on site, they can speak directly with our technical team to ensure they have the support needed to achieve the best possible outcome for our customers. I appreciate that this has not been the positive introduction to Spy Alarms that either of us would have hoped for. I would very much like the opportunity to put things right and rebuild your confidence in us. I have called and left you a voicemail this morning and have also followed up by email. If you could kindly get in touch, or let me know a convenient time for me to return your call, I would be happy to personally oversee your case and work towards a resolution.
Thank you for your time and I look forward to hearing from you.
Kindest Regards

Dear Customer, Thank you for your feedback. We are sorry the cloud connection included with your system upgrade did not work as it should and that it took several visits to get to the bottom of the issue. We understand how disappointing that must have been. We are really pleased to hear that your system is now working reliably without any dropouts. Thank you for your patience while we worked through the problem and for giving us the opportunity to get it resolved.

Slow attention and repair

It took 3 calls and one failed engineers call and 4 days to get a defective battery changed and yes we have a maintenance contract.

Reply from Spy Alarms

Dear Neil, thank you for bringing this matter to our attention. I am sorry to hear that your experience fell short of the standards we aim to deliver. I completely understand your frustration at having to make three calls, experience an unsuccessful engineer visit, and then wait four days for a battery replacement to be completed. Thank you also for your time on the phone today. I am grateful for your honest feedback and the opportunity to discuss your experience in more detail. As discussed, I will be looking into what happened and sharing my findings with the relevant manager to ensure they are fully aware of your experience. It is important that we learn from where we went wrong so that we can continue improving the service we provide to our customers. I have also followed up with an email, and please feel free to reach out to me directly if I can be of any further assistance. Thank you again for bringing this to my attention and for taking the time to speak with me this morning.

Dear Keith, Thank you for taking the time to speak with me this morning. I really do appreciate it. I was keen to personally apologise for your experience with the last minute cancellations to your service appointments. While there are occasions when engineers may be taken ill on the day or experience unavoidable delays on previous jobs, we should be doing everything we can to accommodate customers who have already been rescheduled, and I am sorry that this was not your experience.
I am pleased to hear that, once the visit went ahead, the technician was helpful and completed the work to a good standard. I have added a note to your account to make our scheduling team aware of your experience so that this can be taken into consideration moving forward. I have also followed up with an email following our conversation today. Thank you again for your time and feedback. Should I be able to assist you with anything in the future, please do not hesitate to reach out.

Dear Keith, Thank you for taking the time to speak with me today. It was lovely speaking with you. As discussed, I hope the recommendation regarding your spare fob resolves the issue for you. If not, please feel free to get in touch with me directly using the contact details in my email, and I will be more than happy to help arrange a new one for you. In the meantime, if there is anything else I can assist with, please do not hesitate to reach out.

The engineer was great

The engineer was great, very helpful & professional. Head Office accounts kept billing me for replacement batteries when they are free under my contract. Hence only 4 stars

Dear Richard, Thank you for taking the time to leave us a review. I am pleased to hear that our engineer was very helpful, professional, and provided a great service experience.
I am sorry, however, to hear about the confusion regarding the replacement battery charges. I can see that our Service Department has confirmed that battery replacements are included within your contract. To help prevent this from happening again, I have added this as an active entitlement on your account, which will ensure our system recognises that batteries are covered and does not automatically generate an invoice following a battery change. Whilst I am pleased our engineer left such a positive impression, I appreciate your feedback regarding the battery issue and understand why this affected your overall rating.

The engineer was prompt. But ill informed.

The engineer was prompt, polite and very pleasant. But he said that he was not familiar with the installation of the equipment he had come to fit.
However he persevered and succeeded.
Upon testing it, the monitoring service was triggered as it had not been understood that the alarm is monitored.

Dear JK, Thank you for taking the time to share your feedback. We are pleased to hear that our engineer was prompt, polite, and pleasant throughout the visit. We do, however, appreciate your comments regarding his familiarity with the equipment and the confusion around the monitoring aspect of your system. While we are glad he persevered and successfully completed the installation, we understand that this should have been a smoother experience from the outset. We also apologise for the monitoring service being triggered during testing due to the misunderstanding. Your feedback is valuable and will be shared with the relevant team to help us improve both our preparation and communication in similar situations. Thank you again for your patience and understanding, and for recognising the engineer's determination to get the job completed successfully.
