We have had a house alarm installed for many years and in very good working order. It was installed and maintained by a sole trader who has provided a good service. In the last couple of years however he has gone away for 6 months and been unable to respond to anything other than emergency calls. We looked around for a reputable company to take over the maintenance and monitoring of our system. After writing off many of the national players for various reasons we came across AAI.

The reviews looked good. We found someone who had an AAI installation and they were very complimentary. A short phone call led to a site visit by Andy. He exuded knowledge, professionalism and friendliness. He produced a very detailed specification and competitive quote. The engineers were punctual, polite and friendly. The job was completed on time according to schedule and thus far we have been very impressed with AAI and everyone we have thus far come into contact with. Hopefully this will be the start of a very good long-term partnership.

Great personal service from Andy and his whole team. Knowledgeable, friendly, responsive. Guided us through the process of fitting a intruder alarm replacement and a new fire alarm. Would definitely recommend them.

We have worked with AAI security for many years. They helped install our security and access control systems. Are very helpful and responsive and provide excellent service if the alarm is set off accidentally. They are also helping us with our relocation and in particular Richard has been so helpful flexible and understanding. We recommend this company highly and thank them for their assistance. Maddie

Fantastic service from a friendly and reliable company. I wholeheartedly recommend them to all my friends and best of all, they are a local family owned company. Why go with the anonymous big brands who are more expensive, less friendly and offer an inferior product?

Seriously good company. Excellent service, Very professional which is what you want from a security company. Had our house alarmed with them after a major renovation. Any issues were addressed quickly and efficiently and their office guys are always polite and great to deal with. Our office uses another local company for its security and i can tell you for a fact that AAI are infinity better then them and they quoted the same so win win.

Used them to fit alarm system in my house. They are a very professional company. The installer was very careful not to make a mess and they fitted it very quickly and it's all working fine.

AAI Security are my preferred choice in this field. From their Engineers right up to their Management Teams they are always pleasant and ready to help. They offer an excellent service to our Company. We have worked closely with them for many many years and they now include our Portable Fire Equipment in their service to us, much to my relief as our previous 'well known' supplier was extremely poor and terrible value for money. I would have no problem recommending AAI to anyone looking for a Service supplier. Help is always just one phone call away.

AAI Security replaced an ageing alarm that we had in place from another supplier. From the initial consultation, it was very clear that they were extremely knowledgeable and were the right choice for us. The courtesy, knowledge, professionalism and level of contact demonstrated across the business really impressed us and removed a lot of the headache I anticipated to get the alarm installed. The monitoring station who monitor the alarm are also really helpful and have been excellent when we needed to get in touch with them.

Comparing AAI to our previous supplier, they are better in every way and (somehow) we're saving money too! We'd highly recommend AAI to anyone looking for an alarm system.

Great service. The fitter was very thoughtful and kept the area very clean whole installing the alarm. Great system. And great alarm.

We have been satisfied with each aspect we have moved over to them. Anyone we have recommended them to, has been happy with the results
