Automated call, fake/AI voice, claims to be 'local energy advisor', "Are you the homeowner?" Doesn't use a name, call is disconnected when the script doesn't work with the responses it's getting (such as "Who do you want to talk to?, or what is your company registration number?"
Reported caller:
Local Energy Adivsor (wouldn't believe that for a second)

I did not recognise the number so did not answer. Since no message was left it is clear this was most likely to be a fraudulent call

Local energy advisor- they have a list of all our DDI numbers and are calling them one after another. They need to be stopped!

They said they were from “Insulation Advisory Line” and said our house was showing as not fully compliant for loft insulation. They wanted to do a free survey. They wanted to know my age, as that would determine what grants I could have. I asked if they had a number I could call them back on as I didn’t normally answer questions from cold callers but they said there wasn’t. I ended the call and did 1471 to get their number. There is no such company listed on Google.
