I recently had an intruder alarm fitted and I couldn't be happier with the service. The quote was very competitive, and everything was explained clearly from the start. Joe, the alarm fitter, did an excellent job he installed the system quickly and efficiently with no issues at all. Highly recommended for anyone looking for a reliable and hassle-free alarm installation.

Croxley Alarms recently installed a wireless alarm system in our property. I was impressed with the quality of the initial survey and the installation. The two minor issues we had on the first day were resolved in a prompt and friendly manner. Since then our alarm system has worked perfectly.
