If you are receiving voluntary help do not share financial details like credit/debit card numbers or personal information.
If someone you don’t know calls at your home, always ask for ID and always ensure you are comfortable sharing details like your phone number or address. Only provide information on a need to know basis and if you have seen ID. Do not feel pressured into providing information. If you have doubts about those who are approaching you, and are concerned, it is advised that you don’t engage, and report serious suspicious behaviour to the police.
Remember that genuine volunteers have been instructed not to enter your home.
