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.

the after sale service is hilarious

Great company for Sales and installation with competitive quotes. Once you have done the installation however, its a different story. they mark up 300% on things like batteries for smoke detectors. they billed us a call out charge and 1 hrs labour to change 6 batteries in 2 smoke detectors - total bill to come and change 6 batteries £371.00. They then happily chalked off the labour charge when I complained. They then proceeded to send me a quote of £931 + VAT to change batteries in 16 smoke detectors in the building as a recommendation, charging each battery at 14+VAT which is available on line for 3.88+VAT, they also added 3 hrs labour to change the batteries on the smoke detectors. Ill update you as the saga continues.

Dear Vaibhav, thank you for taking the time to share your feedback. We are pleased to hear that you were satisfied with our sales process, installation service, and competitive pricing.
I am however, disappointed to learn of your concerns regarding the quoted and invoiced maintenance work. We take transparency in our pricing very seriously and would never intentionally overcharge our customers. Our quotations and service charges reflect not only the cost of materials, but also factors such as engineer time, travel, administration, compliance requirements, and the level of service provided. Following your concerns regarding the initial invoice, we reviewed the charges and agreed to remove the labour element as a gesture of goodwill. We appreciate that there may still be a difference of opinion regarding the pricing of replacement batteries and associated maintenance work, and we would welcome the opportunity to discuss this with you directly to ensure all costs and recommendations are fully explained.
I have already reached out to you directly and requested a convenient time to call so that we can discuss your concerns in detail, answer any questions you may have, and work towards a satisfactory resolution.
Thank you for your time & I look forward to hearing from you.

After a few mishaps initially

After a few mishaps initially, either a communication problem with a particular engineer or an engineer not having enough time to call on an appointed time, the Customer Service Team ie Norman and Lionel, worked so hard to rectify my experience and problem with my alarm. Daniel the engineer was excellent as he was so professional and so good in explaining everything to us.

We feel that the above mentioned deserves praise to sort out things when they go wrong.

An awful company...

An awful company ! When they installed a new alarm, they advised us to purchase what we subsequently found were unnecessary add-ons, as recommended by a very pushy and somewhat inappropriate salesman (we should have spotted a rat them!). They subsequently installed an incorrect sensor, put another in an outbuilding out of wireless range which needed further visits to rectify - which they delayed and, in the meantime, exposed us to the potential theft of several thousand pounds - and cancelled maintenance visits on the day! We have since had a burglar alarm installed at our daughter’s home by Verisure, who have provided both a far superior service and product, as opposed to Spy Alarms which installed a flaky system with frequent, annoying spurious panel alerts, despite their (virtually non-existent!) service. Read the small print of their Service contract carefully - it states that the duration of the maintenance contract is “…for a fixed term of two years continuing thereafter from year to year unless terminated by either party…” However, following yet another cancelled service visit, when we tried to get rid of Spy Alarms as you have to do so “ …giving to the other not less than three months’ notice in writing either prior to the first or any subsequent anniversary, of the Completion Date”, despite their serial failures to fulfil their obligations they then sent us a most unpleasant e-mail threatening to initiate a county court claim against us. Whilst some people may be satisfied with a so-so burglar alarm and unreliable installation and maintenance, for those of you looking for something better to protect your home please look at alternative installers before considering this company …

Dear WB, Thank you for taking the time to leave such detailed feedback. I am very sorry to read about your experience and appreciate you highlighting the concerns you have raised regarding the sales process, installation, service visits, maintenance support, and communication surrounding your contract.
I understand your frustration, particularly regarding the issues you describe with the sensor installation, the delays in rectifying faults, cancelled maintenance appointments, and the results this had on your confidence in the security of your property. I also appreciate your comments about the alarm alerts and your comparison with the experience you have since received elsewhere.
Unfortunately, I am unable to identify or allocate your account from your review username, so I cannot look into the specific circumstances surrounding your installation, service history, or the correspondence you have referenced. I would very much like the opportunity to review the matter thoroughly and understand what happened. Please could you kindly contact me directly at b.debeer@spyalarms.co.uk with your account details, and I will personally look into the points you have raised, including the installation concerns, service visit cancellations, and contract cancellation terms. I really appreciate your feedback, and I look forward discussing your experience further and work towards a resolution that works for you.

Had a call back from a technician who was very helpful.
Ivo was his name.
He guided me through getting the parameters changed and back connecting to my router again.
The only downside with Spy Alarms is the outsourcing of the call centre to South Africa.
I waited ten minutes on hold to the worst music ever.
Who chooses call centre music?
Is it to get you to hang up 😀
All good once you get to a technician though.
Thanks Ivo

Dear John Brooks, Thank you for taking the time to leave us a 4 star review. I am so pleased to hear that Ivo was able to assist you and guide you through updating the parameters and reconnecting to your router. I will be sure to pass your kind comments on to him. I also appreciate your feedback regarding your time on hold. While we are a customer service team rather than a call centre, I understand how important the overall customer experience is. I will take your comments on board, and I will discuss the hold music with our Technical Officer to ensure we are choosing something a little more customer friendly in future.
Thank you again for your feedback and for recognising the support you received from Ivo.

Terrible Appointment Scheduling

Spy alarms has cancelled appointments on the day of/the day before the prearranged appointment four times in a row. Bearing in mind I have to re-arrange meetings so that I can let them in, I am thoroughly dissatisfied with their service. They only need to visit twice a year and they can’t even do that. I will be changing to a different alarm provider.

Reply from Spy Alarms

Dear Anna Boden, Thank you for bringing this matter to our attention. I would like to sincerely apologise for the frustration and inconvenience caused by the repeated appointment cancellations. I completely understand how disruptive it is to rearrange meetings and your schedule to accommodate our visits.
I have called and spoken with your tenant this morning and offered my most sincere apologies for the inconvenience caused. I have also proposed a solution to have this matter rectified promptly and will be able to provide the return appointment date very shortly. In addition, I have sent you a detailed email outlining the solution and the steps I will be taking to resolve this issue for you.
To ensure everything has been addressed to your satisfaction, I will add a diary note to personally follow up after the visit and confirm that you are happy with the outcome.
We value your business and I really do not want to lose you as our customer. Please do let me know in your email response if there is anything further that I can assist you with. I really appreciate the opportunity to put this right and restore your confidence in our service here at Spy Alarms.
I look forward to hearing from you.
