What you can expect from Spy Alarms

For a security system to be absolutely reliable there can be no blind spots or loopholes. We don’t believe that can be achieved from off-the-peg solutions. Instead, we provide a whole security solution, which begins with a FREE site survey by a home security expert. We will then design a system specifically for your needs and budget.

Do you have pets? Does your home have specific areas of vulnerability, such as a first floor flat roof or a concealed rear entrance? How does it meet the latest fire safety regulations?

We take all such factors into account when recommending the best system for your home, as well as considering the integration of different systems; for example, a smoke alarm installed in tandem with an intruder alarm. We also offer advice and listen to your requirements with regard to system monitoring and hi-tech features such as Smart Home apps.

A typical install takes no longer than one day and our engineers take great care to leave your property looking immaculate. We know the more tailored and complete a service we’re able to provide, the more secure and confident our customers feel.

Talk to us
I would like to take this opportunity of thanking you for the alarm system you fitted for us. I just felt the service was outstanding, from the promptness of the first visit to assess and discuss our needs and giving us a very reasonable quotation. Also the efficient and professional way your engineers carried out the work and left our house spotless – I would not have even known they had even been there! Thanks once again and I will be recommending Spy Alarms to people in the future.
