Got a call from a woman saying she was from a free loft insulation survey. It felt very suspicious, like one of those automated scam calls. Pretty sure it was AI generated.

Got a call on my London landline (which is on the TPS) at 5.54pm on 1st of April 2026. After a pause, a woman said she was my local energy advisor. When I told her I’m not a homeowner, she just hung up straight away.

I tried ringing a phone number I’m not currently using and ended up just leaving a silent voicemail.

Got a silent call, no one on the other end. Then the form wants even more details - what else am I suppose to say?

Got a call from someone called 'Jan' claiming to be from some Local Energy Advisors or something. Kept dodging when I asked what company she was with. Then, without much warning, the line got cut off on me. The number was one of these: 02035044805, or maybe it had spaces like 020 3504 4805, not sure. Sounded like a scam to me.

Got a call from someone named Jan claiming to be from an energy advice company. Kept asking who she was representing but she wouldn’t give me a clear answer. After a few questions, she just hung up on me. The number she called from was 020 3504 4805, though it showed up in a few different formats. Feels like a total scam to me.

Looks like a scam to me. We answered the call but there was no one there.

Got a call but just went to voicemail with no message left. Checked this site and it showed Core Telecom Limited, so I looked them up and it seems like it might be a spam call. From what I found, they supply phone numbers for businesses that want to ring other companies for enquiries or whatever.
