Roughly how much is it for a new alarm to be installed. currently I have a door sensor with chime thing, plus 3 sensors & keypad. looking to replace it as its bit outdated and temperamental now days. But no idea where to start looking if to go to a large company or private one. Im in the nottingham area but without a rough idea of costs I dont want to post as a job as i may have to wait and save more cash. thanks
