Was an automated thing, knew my first name. Asked me if I was me, when saying yes it accepted it, then kept looping around asking me if I was still there. No idea if it was a scam or not. When calling it back, it said it was Compare Insurance.

Energy - insulation. Very loud, 'your energy' 'understand you're home owner' - fast, spiel from script. Talked straight over me as if I hadn't spoken. When my other line rang at same time with same guy on it, same script, realised this is an AI person. Didn't stay on call for long enough to find out what he was doing, but it was very high pressured selling, and as very loud, suspect aimed at the elderly. Avoid.

Pretending to be roofing insulation installers trying to con you , pre recorded message with gaps in that they think you will reply. Doesn't matter what you say . Report them .

Spam call, automated (AI?) voice claiming to be "James" a "local energy advisor". I am not in the 01206 area code, so this definitely is not "local". Also, this "James" has called numerous times, from other numbers.
-
Called four times in the past two working days. I ignored all of them.

Constantly requesting a cancellation amount of money to close an account we have supposed to have opened.
