By logging in you will also gain access to our best burglar alarms guide, which gives customer scores to seven burglar alarm brands, including ADT, Yale, Veritas and Scantronic alarms, as well as local independents.
We've rated two sorts of burglar alarms. The first are monitored by the company and you pay an annual or monthly fee for this service. The company will then call you if the burglar alarm goes off or alert the police.
The second type are bells-only or those that auto-dial you if there's a break-in. These don't come with a contract and can often be bought from DIY shops.
