Alarm Response

In the event of a fire or burglar alarm activation, the dedicated alarm response team will take immediate action. One of our Key Guards will be despatched by motorbike to arrive at your home in the quickest possible time, and unlike many other security companies, our Key Guards can actually enter your property. All of our Key Guards are trusted, security-vetted professionals, with decades of combined expertise, and are trained to be discreet and sensitive to your home. Banham Key Guards are there to respond not only to alarm activations but also to take action in the event of floods, gas leaks and electrical problems. Above all, our unique alarm response service is designed to provide you with the peace of mind that your home and loved ones are protected 24/7, every single day of the year.
