Victims are strongly advised to avoid engagement, report the calls to the Information Commissioner’s Office and Action Fraud, and contact their MP to press for regulatory action against such fraudulent practices.

I’m totally fed up with these scam calls! I keep blocking them but then another one pops up from almost the same number. This has been going on for ages now. Sometimes I pick up, mostly I don’t. Loads of silent calls too. When I do answer and ask questions, they accuse me of wasting their time. It’s really annoying. Wish there was a way to put a stop to this never-ending bother.

BEWARE OF SCAMS! If you get scammed, report it straight away. Look up ‘action fraud’ on Google, then head to the ‘police.uk’ site. Find the section for ‘reporting phishing attempts’ and carefully read all the info there. After that, enter the details of the scam right into the police system, making sure to add any links or website info. This is really the best way to help the police track how big this problem is.

Called today at about 1.15pm by a Christine from ESE about solar panels. I looked them up online and phoned back using the number from their official site, 08000472985, and it was the same Christine. Since they’re on the TPS list, they really shouldnt be ringing me. I’ve just filed a complaint with the ICO. If you get a call from these lot, do the same - if enough people complain, the company might get fined.

This afternoon at approximately 1:15, I received a call from Christine at ESE regarding solar panel installations. I did a bit of Googling and decided to return the call using the number listed on their official site, which is 08000472985, and to my surprise, it was the same Christine who picked up again. Considering I'm registered with the Telephone Preference Service, they really shouldn’t have reached out. I've taken the liberty of submitting a complaint on the ICO's website. If anyone else happens to receive a similar call, I highly recommend taking action as well; if enough complaints are lodged, the company might just face a fine.

Earlier this afternoon at around a quarter past one, I received a call from a lady named Christine representing ESE regarding solar panels. After a bit of online sleuthing, I decided to ring back the number listed on their website, which was 08000472985, and lo and behold, it was the same Christine on the line again. Given that I'm registered with the Telephone Preference Service, they ought not to have contacted me in the first place. I've gone ahead and lodged a complaint with the ICO website. I highly recommend you do the same if you happen to get a call from them; if enough of us raise our voices, they could find themselves facing a hefty fine.

Today, I received a rather dubious call from a company claiming to be "ESE (Electrical Safety Engineering)", allegedly located in Warrington. They informed me that, based on some so-called "licence solar data", my equipment had expired its warranty and was in urgent need of replacement. They insisted that they were calling from a call centre named "BL Group" in Surrey, supposedly representing ESE. When I requested their contact information, they provided the number 0800 054 2986, which, as expected, turned out to be non-functional. Strangely, I couldn't uncover any records of a company named BL Group residing in Surrey. A quick investigation using the 1471 service revealed the calling number: 02037577340. You can find some information regarding ESE and their questionable practices at this link - https://www.solarpowerportal.co.uk/news/solar_installer_reprimanded_by_council_after_hiccups_led_to_potentially_mis.

Got a call from a number I didn’t recognise, but no message was left before they hung up as soon as my voicemail started. Totally screams scam to me.

This company keeps ringing me at least 4 or 5 times daily, leaving blank voicemails. I finally had enough and blocked the number - what a relief! It’s such a pain having to clear those pointless messages all the time. I even texted them to tell them to stop, so fingers crossed they actually do. Proper annoying and persistent pest, just won’t quit.

So glad I put this number on my block list. They kept ringing me over and over, and my voicemail got loads of weird silent calls and noise from an office or something. Honestly, felt pretty harassed. Definitely best to just block it.

Somebody called claiming to be from BTS and tried to pitch solar panel insurance. Definitely sounded like a scam to me.

I must have missed the call because I didn’t hear the phone at all and they didn’t leave a voicemail. After seeing the comments, I reckon I dodged a bullet!

Got a call and no one spoke, couldn’t tell what it was about. After reading through other comments, it seems like just another scam attempt.

Got a call once, no one answered but I could hear like office noises in the backround. Bit strange and kinda creepy, felt like one of them silent calls you hear about.

I keep receiving calls from these numpties! They just won't take the hint! It's incredibly frustrating! I've started letting it ring through to the voicemail, but they never bother to leave a message! If you're behind this number, do me a favour and just buzz off! Cheers! 😂

They've called me like 3 times within half an hour! I never answered, and to make it worse, they never bother to leave a voicemail. The background was full of weird call centre sounds and some muffled talking. Such a pain! Total nuisance!

Got a call from 02037577340 but they just dropped the call as soon as it went to voicemail. After checking the reviews, seems like this London number is just a total nuisance. Honestly, can’t understand why anyone bothers answering to these cold calls.

Got a random ring about a solar panel warranty supposedly but I've never owned any panels. Quite a dodgy call if you ask me.

Got a call from 02037577340, and it turned out to be those solar panel con artists again. Beware if you get a ring from this number!
