Trading Standards are warning people to be wary of unsolicited phone calls and visits from companies offering home security equipment and services. If you are considering purchasing such a device or service then get three quotes from reputable businesses you trust and make your decision on who to use in your own time. Get recommendations from friends or via www.buywithconfidence.gov.uk. If you are concerned someone is at risk, always call the police. If you are concerned rogue traders are operating in your area, always report it. If someone knocks on your door and you are not sure, don’t open the door.
