Customer Testimonials

Family Run Values, Big Company Performance


Here at Sonic Alarm Systems we pride ourselves on our excellent levels of customer service.
From commercial and educational through to local authority and residential we ensure that the work is completed with as little disruption as possible.


"From the initial telephone query following a fault with our existing system, to the engineer who came to replace parts, your organisation is completely professional. You make it completely clear what charges are likely to be incurred; appointments are on time and the engineers are always extremely courteous and clean up after they have finished.

Having both lectured in Business Management for the last 20 years, we have many examples of poor customer service. It is therefore both heartening and delightful to have personal experience of the opposite.

Thank you for setting such high standards - they are appreciated."



"I had to write to you to thank you and your company for the efficient manner in which you installed our intruder alarm over the weekend.

Not only did everything happen as stated, it is always a joy to be with your workforce who are so polite, willing and helpful.

I have no doubt that we will continue to have a long and profitable relationship with Sonic."



"... I would like to thank Peter and Adam for coming to my rescue on 5th October when my house alarm took on a life of its own and when others were unable to attend.

They were both so attentive and I cannot fault the excellent service they delivered. I now feel even more secure having taken out a years contract with Sonic Alarm Systems."



"A quick note to express my thanks to yourself and the team of engineers that have worked in my school the half term.

The process from start to finish was professional & efficient.

The engineers were polite, approachable, health & safety conscious & above all completed all tasks to a standard. It really felt as if they were trying to do the best job they could.

My governors & I believe we have had value for money from a company that cares about its customers needs.

Keep up the good work."



"... I feel that it is quite unusual these days to receive such a good service and I wanted to let you know how pleased I was and that I was and that I will be more than happy to re-use and recommend your company to others in the future."



On behalf of the staff, parents and governors of X Primary School I would like to thank you for installing our C.C.T.V. system.

The work was carried out by Sonic Alarm Systems and Mr. John Regan led the team of professionals to install the system I was very impressed by the professional way in which Mr. Regan and his team carried out the work.

I am absolutely delighted with the security protection this now gives the school and also having the added bonus of supervising the children's play as a means of eradicating bullying in the playground."



"Both my wife and I are delighted with it and I want to thank you for doing the installation yourself and for the very professional way you went about it. I shall certainly recommend you to all my friends!"



"Just a note of thanks. Sonic Alarms, were the most reasonable quote that I received. Not only that the service that I got was 2nd to none, the lads that fitted my alarm were clean, tidy, very polite and made me feel very confident with my new alarm system."



"In addition, I feel obliged to comment that I was extremely impressed by the speed and efficiency shown by you and your colleagues, and also by the very reasonable price that was charged for the work."



"... Many thanks for very good service and excellent job."



"... Thank you for your efficient work, I will have no worries recommending you."



"... They worked extremely hard over the weekend to complete the installation of the security system and left the school exceptionally clean. I hadn't expected the system to be installed for months."
