Authorised Airtricity sales people have prominent identification (ID) badges and will be very happy to show them. The ID badge has a free phone number which you can call to verify the identity of the agent. Alternatively, or if still unsure contact us immediately on 0845 601 9093. In all cases, we'd advise you never to open the door or allow a stranger into your house unless you're happy to do so and you're sure they are who they say they are.
