2 monthsSo just got a call from 02034810820, someone claiming to be Jo about loft insulation but kicked off with something about mould this time. I just hung up straight away and let them run up the charges. Happened around 3.40pm on 6th May 2026.Jo2 monthsGot a call from an unknown number, nothing but silence at first. Then some voice asked if I owned the place. I just ended the call straight away.2 monthsThe phone rang on my landline, but when I answered, there was nothing but silence on the other end.2 monthsI got a call but nobody spoke or picked up when I answered. So strange!2 monthsHad a call from someone claiming to be from an energy firm, said they could cut my gas costs - problem is, I don’t even have gas! Tried asking where they found my number and she just ended the call. Strange.2 monthsAnswered the phone but no one spoke. BT marked it as a potential spam call. The line got cut off with no interaction, so I've gone ahead and blocked the number.BT2 monthsSome bloke rang me saying he was from an energy company, but I reckon it might’ve been a dodgy scam.2 monthsSomeone rang saying they were an energy advisor from around here. She asked if I owned my place, and when I said yes, she wanted to know when I last checked the insulation in my loft. I told her I don’t have a loft because I live in a flat, and reminded her I’ve told her this before. She just ended the call after that.2 monthsGot a call from an unknown number, felt like it could be a scam or something dodgy. Didn't pick up.2 monthsI got a call from someone saying, 'Hi, this is Jo, an energy consultant for your region. Are you the property owner?' I replied 'No' and then the line went dead. The caller had the same name, similar tone and was pushing the same energy spiel like I've seen in other scam calls from Manchester and Greenock. Definitely looked like another VoIP scam.JoManchesterGreenock2 monthsI picked up my landline and said hello, but all I heard was silence before they just hung up.2 monthsI picked up, but there was nobody there on the other side.2 monthsGot a call from some energy advisor named Janet again. Told her to quit calling me and she just ended the call. Blocked the number straight away.Janet2 monthsGot a call from an 0203 number the other day. I answered but there was silence on the other end. Told them it's pretty cheeky to ring up and not say anything, then they just hung up on me. I've gone ahead and blocked that number now. These 0203 calls keep coming in nonstop, it's getting ridiculous.Submit Your Own Report (020 3481 0820)
